Will i damage my t-case?

I have an 88 YJ with a set of tires that are pretty bald. I have a set of Dunlop Rover A/T 235/75/15 for the back that are about 50% thread and a set of Scorpion Radial A/T 205/75/15 with about 80% thread for the front. If I run a set of tires in the front with different thread and slightly narrower than the back can i damage the t-case or front diff?

No you should be fine, the only time you run a risk is when you run 2 different size tires on 1 axle than you run a very high risk of grenading your diff.

If you have tires front and rear that are different diameter they will obviously rotate at different speeds. But, unless they are wildly different and / or you engage 4WD on dry pavement it should be ok for a while.

Having different sizes on the same axle would make no difference; the whole purpose of a differential is to allow left and right tires to turn at differing speeds.

This is a good education

Call me old fashion but "Never run different size tires on a 4X4" was what I was taught. just my 2 cents. Look on craigslist for some that match.

Warning: This poster has infinite knowledge of useless information and redneck tendencies. Use info at your own discretion. :wave:

Those two tire sizes mentioned are just a width difference as far as I know which will not make a difference to your Tcase. You would have more of a problem if say you wanted 33's up front and 35's in the rear.

Few things:
  • Would not affect anything in 2wd anyway
  • When you're in 4wd there should be some give/slip (not dry pavement surface) anyway so that helps
  • THey're the same height, so it should be fine

Those tires are not the same diameter. The 235/75-15 converts to 28.9 inches and the 205/75-15 is 27.1 inches. You will be fine in 2WD but do not run it in 4WD in any place where there is much traction. You will put a lot of stress on your transfer case.

tire diameter is what would determine this. if they are say 31" on every tire, than you will be fine. i used to run 2 different tire patterns on my XJ when i didnt have the money, same size.. never had a problem
