4wd tire size
If I have a tire go bad and have to get a new one, will I need to replace both on the same axel. Can I use and rotate two different milage tires to the front or rear end with out any problems, or will this cause problems with the differentials?
Re: 4wd tire size
The long answer. Tire rotation is essential! The numbers are slightly different between manufacturers, but essentially, with the AWD/full time 4wd nature of these vehicles, in order to get a "new tire" if one blows, they need to be within 2/32" of each other in tread depth on the same axle or 4/32" on different axles (front to back) or you will need to replace more than just the one tire. It can and will cause damage to your diff's and trans-axles if you don't.
When this sucks if if your tires are more than half worn, and you have to replace one from say a blow out. New tires are 10/32 or 12/32 new. Half worn tires will be 4-6/32....which is more than 2/32 difference between the tires on the same axle. So you have to replace both on the same axle. Well, those new tires are now more than 4/32 difference from the other axle...now you need to replace those as well. If you don't, you risk damaging your trans axles which costs alot more. See what I mean? It's really a crappy deal.
THis is the same issue that alot of newer cars with AWD are having that people don't realize. Sometimes, if you get a flat, you need to fess up for a full set of new tires rather than just getting one. I worked at a Sears Auto Shop for almost 4 years and had some pretty ticked off customers when I told them that.
I hope this answered your question!
