DIY: Spare tire setup (WK1)

Finally finished up this project. Since I'm not running runflats and I don't trust fix-a-flat or an air pump for major flats, I decided to setup my own spare tire kit for peace of mind.
Parts needed:
18x4 Chrysler Pacifica compact spare ($45 ebay)
Hub & wheel centric spacer so the rim clears the brakes ($65 http://www.motorsport-tech.com/)
Extra set of lug nuts ($8 Pep Boys)
Jeep jack kit ($40 ebay)
Misc nuts & bolts ($5-$10 Home Depot)
Wheel cover ($20 Pep Boys)

While I was sound deadening behind the panels I noticed this bracket on the driver side rear fender. It was in the perfect position for the center hub on the compact spare. If I recall correctly, this was a 6" bolt with washers and a lock nut.



The hard part was drilling through the side panel at just the right spot. I didn't get it perfect but it's hidden by the washer and the wheel... Note: I was told by another member here that I could have installed the bolt, then taped a laser pointer to the opposite side of the car pointing at the end of the bolt, then remove that and reinstall the plastic side panel and the laser dot will give a perfect drilling position.



As you can see, the bolt aligns to the center of the wheel hub. The wheel must be on the floor of the jeep, if you put it on top of the false floor, it will be too tall. I picked up a wing nut, a large washer and a strip of steel plate with a hole drilled into it to secure the wheel.



I used a sawzall to cut a relief in the false floor for the tire to go through, and a little clearance on the end of the removable tray. I probably could have done this much nicer, looks like I over cut it a couple inches, but it turned out ok.



Here's the adapter I had built by www.motorsport-tech.com It's hub centric and wheel centric, which is the safest you can possibly be when running a spacer... It is 1.25" thick. The extra lugs I picked up at Pep Boys for around $8. To store this, I just bolt it to the wheel and finger tighten the lugs, so it's completely out of the way.




Need a little air in the tire, it had 32psi rather than the recommended 60psi. Otherwise it drove fine and there is plenty of clearance everywhere.



Buy the spare tire cover of your choice. No pics of the jack kit, but it's a standard Jeep GC jack kit from a junkyard and it mounts right into the spot behind the passenger side rear seat.
