On the way to the tire shop I pulled out the ABS fuse and laid some rubber down during an obnoxiously loud all wheel drift. The ABS/ESP warning lights came on but as soon as I put the fuse back and restarted, they all went away.

can you guess which tires are mine?

hummmm.... might be nice with a 3" suspension lift

http://www.dubreggae.com/SRT/2234.jpg

the rotors have a tiny little bit of scoring, but they're quiet and smooth so I'm not worried about it.

went to lunch, came back an hour later

.....

now that's what I'm talking bout!

I noticed the acceleration is a bit off due to the much larger diameter, but the trade off is that I have a much smoother ride, and maybe even better handling thanks to the softer rubber compund and extra width.

I didn't even bother shaving down the bolts on the front suspension uprights, they had a good 1/4" of clearance. Also I'm happy to report so far there's no rubbing issues at all. The only problem I could imagine is during full compression of the front suspension, maybe the tire could contact the fender liner, but to me that would be a minor issue.

Now I gotta start working on my next mod... :)

Sweet tires!

Is pulling the ABS fuse basically the same as the GSM ESP switch I've been hearing about? From what I've read it sounds like it. Which fuse is the ABS?

idealrides
03-30-2006, 07:19 PM
Thanks guys, I like them too!

I pulled the fuse under the hood labeled "ABS PUMP". Also there's another fuse labeled something like ABS RELAY but I left that one in place. I don't know how this differs from the GSM mod, but it was clear to me that there was little or no traction control without this fuse. I must admit having a switch like the GSM mod would be nice so that you can do everything from the driver's seat.

Looks Great !

Please fill us in on any handling / launch / speedometer / ride quality differences as you spend a little more time with the change.

Try the GSM ESP mod, it is way more convenient (and more expensive) than pulling a fuse.

Again, looks great!

Ideal, new tires look good! Do you have any pics of before and after the tire change? It's tough to imagine the comparative difference in the wheel well clearance and the look of "more tire, less open space". When you get a chance give us input on how it handles in the rain, compared to the old tires.

Those are the excact tires (different size obviously) I put on my 300C SRT8 to replace the f1s. I had the same experience..smoother ride, better on wet pavement. No noticable difference on hard corners or acceleration.

these are the only pictures i have that show the fender gap. I haven't driven them in the rain yet, but so far the biggest difference is the smoother ride and more satisfying appearance. It seems like these size tires are what it should have come with. I don't remember the exact price but the total including install and a polish and wax job was just over a grand.

well it could be my imagination but it seems slightly less jarring when you floor it. I'm not surprised or disappointed because the diameter is something like 5% greater than stock and they're probably heavier, but I didn't weigh them. I've done this to a lot of cars/trucks/bikes I've owned, all with similar results. (although I usually wait for the old tires to wear down, in this case I couldn't wait.) It not only produces a more comfortable ride, but it gives some legitimate incentive to make power upgrades. :D

You increased tire size so performance will suffer, he is correct.

Are the Toyo's run flats? Are the all seasons (they dont look it)? They look awesome. This will probably be my next purchase. Thanks in advance.

07-17-2006, 10:34 AM
No they're not runflats, but I didn't want runflats because their sidewall is so thick that it makes the ride more harsh, plus runflats are heavier. I just checked and they do have the mud+snow rating, and are V rated to 149mph.

Not at all. I live on a small Caribbean island so I'm never too far from a helping hand. A couple years ago the last time I got a flat tire, it was 1 in the morning, I called one of my assistants he came in 10 minutes with a spare car. I drove off in but he waited with my car until a tow truck came. Next morning by the time I got to work the tire was fixed and my car was in my parking spot, washed, detailed. For a moment I felt like a kingpin. :)

I've been on Toyo Proxes for the last 5 years. They are outstanding tires, and handle great in wet conditions, and pretty fair in snow too. I'm also a no spare guy.... been doing that for years too. My only thing is that getting ready for a road trip takes about 5 minutes longer, because I will look online to find out where tire repair joints along my route, are located at. I also always keep my AAA up to date.

nino, yes there are significantly smoother/more comfortable over rough roads. Not amazingly dramatically different, but I did notice the difference and the stock tires were too uncomfortable for the roads here. On old friend of mine recently started a speed shop and he's a Toyo dealer so I got them from him for around $1000 installed. His website is www.illegal-business.com (http://www.illegal-business.com)

What is the widest tire we can fit on stock rims?

bobholthaus
12-16-2006, 09:14 AM
Gentlemen- I currently am trading in my Touareg for a GC SRT8. I have Hankook Ventus RH06 tires on my Touareg and I've loved them. Great ride, great handling, low noise, very high tread ware. I had the Toyo Proxes before the Hankook's and they wore very quickly. Just my two cents, and they may not handle as good, but the Hankook's come in the same size as on this post and you can get them fairly cheaply from discounttiredirect.com ($160 for rear, $150 for front, shipped) and with a 420 treadware rating, they should last a lot longer. Great look though, that's for sure. Thanks for the post. Please keep us updated on any rub problems! Oh, and they're load rated XL for the weight, but I'm not sure about the speed rating for the fronts... I think it's a W and I'm not sure how fast that is. Although I dream of topping out at 161, it probably won't happen too often.

i've got the same tire on my silverado and love them. mine are about as wide...but a little bit shorter 295/50/15. got some on order for my TBSS as well. just dont forget about the 149mph rating...i hear these jeeps are capable of WELL above that. the SS is pretty much limited to 150-155, so i'm not that worried about 5/6 mph.

I noticed that Toyo also makes the Proxes S/T's in a 285/50R20 and a 255/50R20. For those of us that want the tire confined within the wheel wells, wouldn't this be an OK way to go. Same width as stock but a little more profile for the better ride. Of course you'd have a tiny bit more rake in the back, but there should be plenty of room for the tire. Might even look good cool at the track. :D

bobholthaus
12-22-2006, 03:04 PM
Laddcruzer- whoa man... are you familiar with aspect ratio's and "plus 1" sizing? The way a tire reads, 285/40-20, means 285 mm tread width, 40 aspect ratio, which means the sidewall of the tire is literally .40 or 40% of the width of the tire tread, in mm, in this case 285x.40=114 mm. The last number is the diameter of the wheel. On front, stock is 255x.45=114.75 so the sidewalls on the front and back are only .75 millimeters apart, making the overall dimater of the front and back wheels almost exactly the same. I've been told that for AWD cars with ABS and traction control, the tire diameter matching is essential or the car thinks your spinning a tire or something and can cause havoc. In this dudes Toyo example, if you do the math, 295x.45=132.75 and 265x.50=132.50 so his sidwalls are only .25 mm apart, but are approx 18 mm taller (132-114). So, his diameter increased all around, but by the same amount. In your example to keep the width the same, 285x.50=142.50 mm and 255x.50=127.5 you'd have the two sidewalls off by 15 mm, which on an 86 Trans Am (with glasspacks, no less), the rake would be fine but on an AWD vehicle I don't think it would work (or it may not be good for the transfer case). So, you could go 285/45 and 255/50 and be off by .75 mm and still be fine. (Or 285/50 and 255/55 would probably work too). Do you understand? If not, please go to tirerack.com because I think that they have a good explanation of this. Hope this helps.

And back to my original post about the Toyo's vs. the Hankook Ventus, I've had them both and the Hankook, for noise and wear and weather performance, wins hands down all day long. But, the Toyo's, for dry grip, are likely a little grippier because their treadware rating is lower so they are naturally a softer rubber which equals more grip (and less wear).

bobholthaus,
I certainly appreciate the time and education regarding tire specs and ratios. My idea sounded like a good idea at the time. I will modify my thinking and thank you for your imput. I did find that in researching your suggestions that might work using the stock width,(285/255) that there isn't those combinations available for the fronts at this time. At least that I can find. 255/50 and 255/55 just aren't made yet. I even checked the Hankook's. So we are stuck, it seems, if we want to remain in the stock width, with the stock run-flats. Or of course going to the 295/265's. Or a 22 inch wheel. Any other direction or suggestions from you would be welcome.

No problems or flats yet, actually I'm so happy with them that I bought spares and mounted them to extra front and rear SRT wheels, just in case anything happens. I guess I'm an "ounce of prevention" kind of guy. I still feel they're one of the best mods especially if you live in an area with crappy roads.

What stock tyres do you run in the US ?

My UK model came with Pirelli Scorpion Zero P245/45 R20 Run flats on both front and rear.

I must admit my first comment when I saw them (especially on the rear) was "are you sure their the correct size".

I've just had a look on the UK Toyo web site ( http://www.toyo.co.uk ) but I cannot see the 265/50 size.

What's the idea of having different sizes on the back and front ? (Just cosmetic ?)

I got the Yokohama Parada Spec-X 255/45-20 and 295/45-20 and the car immediately started to misbehave. It simply would not drive properly due to front axle binding. My dealer told me that I could not put any other tire but the original OEM's as replacement. I personally think this is absurd.

So now I have four brand new tires that are worthless to me.

This does not make sense.... Anyone have any ideas?

This is a neat little tool that will help you with +1 sizing. It won't answer fitment questions, but it will help you understand what width/aspect ratios keep you closest to the original diameters, as well as what effect you're going to have on your speedometer and performance. It doesn't address fitment issues, but more posts like this from the OP seem to answer that.

And I agree, filling up more of the well really looks nice.

Please read my post above. You're running two different diameters on an AWD car so one end of the car is spinning faster than the other. If you have different tire widths front and rear, as on the GC, you can't have the same aspect ratio front and rear. One has to be different to compensate for diameter. In a nutshell, when you mutiple the width (ex. "285") by the aspect ratio (ex. "45") the resulting answer has to be as close to one another as possible (front and rear). Two of your tires are fine... you just need to buy two more that make the equation work. Your dealer doesnt know what they're talking about.

This does not make sense.... Anyone have any ideas? The problem isn't that you changed tires, or even that you changed sizes. The problem is you did not choose front & rear tires of the same diameter. Your Yokohama setup's front tire is 1.4" shorter than the rear tires which is a strict NO-NO with the GC's 4WD system & is causing the binding of the drivetrain. The Parada's are available in 265/50/20 size which is what you need for the front's to match the diameter of the 295/45/20's on the rear. If you could trade the 255/45's for 265/50's you'd be in business.
I considered the Yokohama Parada's but went with the Toyo Proxes ST's, as this thread's starter did, in 295/45/20 & 265/50/20 and love this setup.

I am ABSOLUTELY befuddled that a tire shop would be stupid / greedy / oblivious enough to sell you those sizes. Anyone with ANY knowledge should have told you that on this awd vehicle your OD (overall diameter) must be identical (or nearly so) in te front and rear.

1. He could have ordered the tires over the 'net without ever speaking to anyone.
2. It's an owners responsibilty to determine which aftermarket products, sizes, etc. are compatible with his vehicle.
3. Even if he visited a tire store, the SRT8 is a limited production vehicle that few tire dealers have seen & may not be in their software to assist them in tire selection. This does not excuse any tire store however & if he sought fitment advice prior to buying the tires the retailer should absolutely be held responsible for resolving the issue.

So here is my point in a nutshell.

If a poster posts something that could possibly make him look uninformed / uneducated (on a specific matter), I find it's more beneficial to the life of the board as a whole, to divert the blame in the situation (if at all possible) to someone other than the poster. A happy poster comes back and helps this board become populated and in turn, a better place for us to hang our hats. If a poster is made to feel foolish, they typically don't come back. I'm NOT saying your intent was to make a poster feel foolish, but how much easier is it to get the point (the point was: find a new dealer-- the one you're using is stupid, and gave you HORRIBLE misinformation) across without pointing out any fault of the poster. The poster has learned their lesson to do more DD without ever pointing the finger at them-- even if it should be.

If they failed to provide this, which I am sure we can all agree is the case, they should offer to fix their mistake without hesitation. Best of luck to you getting your "situation" resolved!IF "mehvarz" went into a tire retailer and purchased these tires you are correct, they should resolve the issue. If the tires were ordered from an internet dealer & he simply went by & had them installed it's a different deal. Yes, a top notch tire shop might have caught it but most would have simply had whoever was free for a few minutes install the customer provided tires.

I know this is an older post but I am curious as to why some of you went to the 295-45 and 265-50 Proxes as opposed to the 295-40-20 and 255-45-20's which would seem to be a better match to stock and how you feel about them now that you have had them on for awhile? I have also been watching to see if Toyo is going to make their Proxes 4 up to a 285-40-20.( their largest now for our rears is a 275) The Proxes 4 is an ultra high performance all season that, after having a set on one of my cars, is incredible in the rain and also does extremely well in the snow.

Hey!!!

You have to go back in the postings & read about the overall diameters of the F & R tires needing to match or be very close in size do to our AWD system. Many of us have switched to 275/40 fronts & 315/35 rears. This tire combo is 28.7" diameter for bothwhich is good because they match, where our stock setups are 29.0" for both. Which basically means with the new set up when your speedo reads 60mph you are actually going 59.4mph.

Here's a site I use to determine what tire sizes will meet any stock setup. Once you plug in the stock size & the tire you think you want it will give you every reading you need to make a final decision.

Thanks MoparNut; It becomes a head scratch because Goodyear's site shows our 285's to have a O.D. of 29.0 inches and our 255's with a O.D. of 29.1 inches. That is why I was looking at the 295 Proxes which Toyo has at a O.D. 29.2 and their 255's at 29.1. Both set-ups have a .1 differential. And the sizing sites charts do not always match manufacturers' stated dimensions. Grrrrrrrrrrr.

Thank-you sentipede; I will again repeat, if you go to the manufacturer's site you will see that the factory O.D. is as I stated-Goodyear RSA-EMT--255-45-20--29.1 inches and Goodyear RSA-EMT-- 285-40-20 --29.0 inches. Ditto with the Toyo Proxes S/T in sizes I stated. You just recomfirmed that stated O.D.'s on tire charting sites differ from the O.D.'s in the manufacturers' site.

The manufacturer's stated size is always more accurate than the size determined by a calculator.

Tires of the same specified size, especially from different manufacturers, usually have a slightly different actual size.

Idealrides, any rubbing issues yet with this set-up?
You need to clean out your pm box. ;)

I'm running 275/50 and 305/45 without any problems.
The fronts have a slightly larger diameter, but well within allowable tolerance.
