jlane_87 Posted November 8, 2009 Report Share Posted November 8, 2009 Tried a search on this topic and couldn't really find anything. I have 18k miles on 50k mile tires and don't want to replace all 4 because of 1 bad tire. Has anyone experienced any problems in replacing 2 tires on an AWD? Or only 1? Discount Tire will replace 1 if the tread wear is within 2/32nds of the other tires from what I hear. Anyone with experience in this?

Punisher Posted November 8, 2009 Report Share Posted November 8, 2009 You should be replacing all the tires to the same size otherwise you risk slowly smoking your viscous. But 2/32s is really not much and I'm sure they have had experience with AWD vehicles before so I would say go for it. Quote Link to comment Share on other sites More sharing options...
misterp Posted November 8, 2009 Report Share Posted November 8, 2009 I *think* the allowable size difference is more than that, I think you're fine if all tires are within 1/8" of the shortest tire on the truck; but that is my opinion, I don't have a shop manual spec to back that up. I will say this though, none of the AWD trucks have tire wear issues like you describe, where just one tire goes bald - they all wear very evenly even on my truck and my alignment scares every front-end guy that's had my truck on a rack. Find whatever problem is causing your excessive single tire wear and fix it. Mr. P. Quote Link to comment Share on other sites More sharing options...
05_gaSShog Posted November 8, 2009 Report Share Posted November 8, 2009 (edited) So I guess this means that replacing the 2 rears for a 305/50-20 from the stock size for about 2 weeks is a no go, too. Mr. P....I also PM'ed you about the question. Edited November 8, 2009 by 05_gaSShog (see edit history) Quote Link to comment Share on other sites More sharing options...

I should have clarified why I need to replace the tire- found a pretty good gash in the tread (can see a tiny bit of one wire of the belts when I pry it open). It still rolls fine- no vibration and stays closed unless I pry it open. But I know its a time bomb waiting to explode at the worst possible time. If I bought a new tire it would have a 14/32 tread depth. The rest of them on the truck are about 10/32 (using an inaccurate means of measurment). My thought was this is close enough to just replace a pair (for matching side to side) Quote Link to comment Share on other sites More sharing options...
