I was wondering if i needed my spare tire to be the exact same size as my other tires since I have a limited slip. I think that I am ok, but i wanna make sure.

 

As long as it is not to far off you will be fine. I have 235 spare and 265 tires.

 

^^235 and 265 only refer to the tread width in millemeters...nothing to do with height. It's diameter that matters.



Does not need to be the exact diameter. It's a limited slip, not a full on locker, so it'll compensate for it. But I do suggest having the same diameter spare.....or....have a smaller spare and should you need a spare for the rear, take a front tire and put it back there, and put the spare up front.

 

It's a good idea to, especially on the back or it will mess up your rearend/gears etc.

 

It will be best for the differential to have the rear tires the same diameter. it will "work", however the constant slipping will heat/wear the clutches pretty quickly.

 

But wont i have the same problem in the front?

 

No if you haven't done any work to the front of your truck the diff is open..

It should affect it too much.. I wouldn't run the tire for long up front it would eventually give you uneven tread wear..

If you have larger tires its a good Idea to have a same size spare tire.. Its just a matter of where to put it.... In my case I'll be building a tire carrier off the bumper before I head up the haul road for Caribu hunting this fall.. They say take two spares on that road.. So I'll have the stock and a full size...

 

Unless you've put a locker up there, you wont have that problem...from the factory, our front axles are open. Doesn't matter if the OD's are different up front...and I dont think it really matters if the OD's are different for the rear if it's limited slip. If it's lockedinthe back or thefront, completely different story.

 

True.. its open when its not in 4x4, my bad

 

It does man, it's like you are constantly turning and the clutches are slipping. Now it wont be a OMG it's going to grenade like a locker...however, if you go, i'd say more than a mile, the life of your clutches will lessened dramatically. They just aren't made to do that.
