I have firestone mud terrains on my truck bought them used about a year ago. The one tire was worn funny cause of his alignment and now us pretty bald. I had it on the front for a year but now that snows coming I moved it to the back so I would have two good steer tires but now have one bald and one good tire on the back. Will this hurt my rear end at all and what if I replace the bald tire with a cheap all terrain of the same size can I run two different type tires on the back
One bald tire won't hurt anything other then being able to go somewhere. As far as running 2 different brands of tire as long as they are the same size you will not have any pulling. If you run 2 different size tires your truck will pull towards the smaller tire. It is not as bad on the rear as the front but it can still pull the truck.
That's true. If one tire is taller than the other, the axles (right and left) will be turning at slightly different speeds as you drive. If your truck does not have a limited slip unit in it (some didn't) then it won't matter as long as the height difference isn't huge. If it does, and it probably does, you'll be wearing the unit out a little every time you drive.
well the difference were speaking of in diameter is one tire has about 3/8in of tread while the other had 1/4in on one side and slopes to bald on the outside because as i said the guy i bought them from had bad alignment. so is this really going to hurt the rear. do the axles not spin at different speeds every turn you make?
yes, they turn at different speeds every turn you make... and you usually take tight turns at slow speeds and then go straight for a while and everything cools down...
if you're constantly turning at different speeds, it accelerates wear
The small difference in height you describe will not hurt anything. We were just wanting to make sure you didn't have actual different height tires on the two sides of the rear.
you should be fine, yes they turn at different speeds when you turn. Best policy is to replace tires in pairs, both fronts or both rears, or better all 4
even having 1 bald and one good tire is going to cause some excessive wear of a limited slip carrier.
Its not the end of the world, but i wouldnt be driving around forever like that, rebuild kits for D80s run ~$500
If its an open carrier, giver chit. It does cause some wear of the cross pin from the spiders slowly roatating all the time. but just a single peg leg burnout does a million times more wear LOL
Well I put a set of 4 265/75/16 mud tires on the rear and kept two good 215/85/16's on the front. It worked out OK until I spotted a slow leak out in the boonies and I switched out one of the rears to the front (truck never came with a spare). With the smaller tire on the outside when the truck went into a rut the outer rears had traction and the inners were suspended. I didn't have any real troubles besides the rear of the truck wanted to pull sideways. On the highway the inner took up most of the load and it tracked straight. And I only put the slow leaking 215 on the rear to keep the rear "balanced" if that makes any sense. Otherwise I heard (hearsay) that it would've been better to pull both outers and run on inners as it wouldn't stress out springs/hardware on a long drive (can't remember where I heard that from though :confused013
well i think i'm buying one new tire tonight it's just to get me through the winter i'm not even sure if im going to keep the truck much longer. i will have the two different tires on the front and the mt's on the back
