Hey Guys,

I have a rear tire that "blew" the inside of the sidewalls. It doesn't look like an issue on the outside, but upon breaking down the tire, it is full of rubber crumbs and can see many spots where the plys are showing through.

The spare is 245/70/17 and the other tires are 285/70/17...is it ok to be driving around tire shopping with the spare on the rear, or is it likely to burn up the rear end?? Or should I swap it with a front tire and have the same size tires on the rear??

 

Keep it in the rear, if it was on the front you would feel it in the steering wheel.
Just go slow like the little donut spares. Not crawling, but don't race.

 

I would put it on the front...and drive directly to wherever you're having it fixed. 2 different sized tires are not good for a lsd.

 

yes... put it in the front... Do not have different size tires in the rear- and as said above it is not good for the LSD. The front is Open so it doesnt matter as much..

Id rather be pulling to one side instead of blowing a rear diff!

 

Definitely on the front, LSD or not.

 

Yep, never want the tires on the rear to be different

 

What you need to do is buy a new tire for the blown out one (or a set). Then have the tire store put the best used tire you have on the "spare" wheel. That way next time all your tires will be same size and if you need to use a spare, you won't have to worry where it goes. Good luck. I'd go to discount tire also.

 

Ok, I know this isn't the best idea...and will prolly look ridonkulous, but what if I were to put two 245 up front and two 285 in back (as long as I promise you guys I won't put it in 4wd) for a few weeks until I can afford the Nittos I want...

would that be like an aweful thing to do...the tire guy said being 4x4 they have the be the same, but I don't see how it would affect anything if 4wd is not engaged...I understand the tire height changes the gear ratio a bit, but some of you guys mentioned in my thread last year that I could put 4.56 in back and leave front 3.55 until finances become available, as long as I don't engage the 4wd...so I don't see why mismatched tires between front and back would be any different, as long as they match on the same axle...am I being retarded, or will the 245s be ok up front for a while?

 

You can run staggered sizes in the rear and the front just as long as the L an R is the right diameter (285x2 in the rear and 245x2 up front)

EDIT: Just noticed you are 4WD so take my post as a grain of salt.

 

Yeah, that was the idea, I just don't have the cash to get it done today...so I'm trying to find the best way to get by until I have the funding to do exactly as you said. Thanks for the reply though.

Any more input from anyone on staggering between the front and rear as long as 4wd is NOT engaged??
