Today's research data after reading many, many threads on replacement tires. Topics include diameter deltas wrt T-case issues. I'm in the market after my GY wear issue... I thought I'd share what I collected today.
Avoid side wear issues...BE SURE TO SET ALIGNMENT CAMBER DOWN TO -0.125 to -0.25 range (per jim383)
STOCK RIM SIZE = Front 9.0, Rear 10.0 (some tires below are outside of this spec)
Question: anybody have issues with rubbing on wider sizes on OE suspension, if so, what model?
Question: any reason to be concerned with buying tires outside of manufacture's rim width specs?
I learned that not all brands are available in OE and/or larger sizes.
Enjoy...
