Widest Tire on an 8" wheel/rim?

KingairPilot · 09-14-2009, 05:04 AM

Howdy everyone,

Ok, so I was wondering if anyone out there puts the 35/12.50/17 on a stock 8"wide wheel...???...??? The website says you need an 8.5" wide wheel for the tire, is that bullpucky? What is everyone doing?

I have 2006 2500 wheels on my longbed 2003 quadcab 4x4, with a 2.5 leveling kit, and now want to put the 35" tires on it. The rub is that my wheels are only 8" wide... I want a true 35" tire, but do not want "d" rated tires (8 ply)....

What to do, what to do!

i bought 35x12.50x17 saturday and went to CJs to get them put on. They told me it wouldnt fit on my rims (7.5" wide). i went to my buddy's shop and got him to try putting one on. they fit like a charm. id say youll be fine

Folks run 33s and 35s all the time on 8" rims. Tire pressure may be more critical with the 8" rim than a 9" for even wear. The rolling resistance will be a bit more along with increased tire wear and a bit less fuel economy with a under width rim.
This could have something to do with some tires lasting longer for some folks and others running the same tire having much less tread life.
