canadianVRss Posted January 29, 2013 Report Share Posted January 29, 2013 Ive been selling rims an tires for 10 years. And on an AWD you will kill your tranfer case, front or rear diff, and hubs. It'll take some time but something will go! I run 275/55/20 and was gonna go 265/55/20 do to a miss order and my wholesaler told me it will hurt and even kill one of the 4! Wait a minute... He told you that if you change all 4 tires to 265/55/20s That it'll F something up with your drivetrain? Ahh haha..... Haha... Hahahahaha Quote Link to comment Share on other sites More sharing options...
ssfast Posted January 29, 2013 Report Share Posted January 29, 2013 It's all about rolling radius! If the tires are out by 1/8th of an inch it can start causing problems to more its out the bigger the problem! Dosent seem like much but it is!

If you truly believe this then you better go outside and check the psi in your tires and make sure they're EXACTLY the same or else your going to be off diameter. You could be off a hell of a lot more than 1/8 of a inch with a semi low pressured tire. Don't sweat the small stuff. Use common sense and everything will work out. There IS a tolerance, we aren't driving around with a tube of nitroglycerin under our trucks waiting to explode if our tires are off 1/10" Quote Link to comment Share on other sites More sharing options...
JC03SS Posted January 29, 2013 Report Share Posted January 29, 2013 I'm pretty sure as long as all 4 tires are the same size being what ever they are 235 or 305 it's fine but not a 19" rim in the front with a 235 and a 20" in the rear with a 295. On an Awd. Rwd it don't matter. Quote Link to comment Share on other sites More sharing options...

They are more sensitive than most think. If you blow out one tire you shouldn't just replace that one due to the difference in overall circumference and Rollin radius! All four should be changed!

That I agree with you on. A tire can wear down quite a bit. But if I was going to change my tires and wanted a little more traction I wouldn't hesitate to go with NEW 305/50/20r (32.01" over all diameter) in the back and NEW 275/55/20r (31.91" over all diameter) in the front. Like I said, 1/10 of a inch could be as much as a slightly under inflated tire. Quote Link to comment Share on other sites More sharing options...
1BAD2K Posted January 30, 2013 Report Share Posted January 30, 2013 Pull the front shaft! Problem solved! True! If you ruin the tcase by pulling the front driveshaft, you wont have to worry about ruining it with different tire heights LOL Quote Link to comment Share on other sites More sharing options...

ThatTallCanadian Posted January 30, 2013 Report Share Posted January 30, 2013 Actually I have a question about this now. Obviously you want rolling diameter as close add possible all around. But what about weights? Would a wider and thus Heavier wheel in the rear throw off the balance at all and create drive trunk problems? Since the wider wheels will be throwing more resistance at the system than the front, and take marginally more power to turn? Quote Link to comment Share on other sites More sharing options...
rdavid0412 Posted January 31, 2013 Report Share Posted January 31, 2013 WOW!!!!!!! How about someone tell me why LAMBO's are AWD and have different width tires? Honestly man you CAN run different width tires as long as the overall height is the same. It won't cause any damage. Their is even about a 2-3% tolerance for differance in gears . You could get away with a 4:11 ration in the rear and run a 4:10 in the front. Will it cause long term issues? Possibly. As with any modification we do to our trucks. I think its a cool Idea and I know it will work. Quote Link to comment Share on other sites More sharing options...
powell Posted January 31, 2013 Report Share Posted January 31, 2013 I'm pretty sure the subey guys run wider wheels in the rear with big dishes. Like said above its all about rolling diameters. Weight, width, color whatever... Doesn't matter as long as its close. 32.01 and 31.91 I wouldn't worry it's only .3% different. Quote Link to comment Share on other sites More sharing options...

canadianVRss Posted January 31, 2013 Report Share Posted January 31, 2013 Now if you wanted to push the "weight" argument that the rear tires would be heavier than the fronts therefore taking more jam to spin, I could kind of see that, but that seems shotty at best.
