2 different tire size and fulltime 4wd=BAD??

[FreedomIsntFree]

I replaced the tires on the blazer with cheap used ones from discount tire. All they had were a pair of 265/70 and pair of 236/75. So I put the bigger ones in back. I know I can't run them in 4Lock but will it hurt drivng in 4HIGH? Just curious. I'm new to the whole fulltime 4 wheel thing.

we had 31's on the back of our jeep and stock tires on the front for a while. everytime we used 4 wheel drive, there was an awful popping noise, no telling what was binding up in the t-case...

I wouldn't run different tires unless they were very close. then I still probably wouldn't.

they are very close to the same diameter.
the 265/75r16s are 30.6" in diameter
the 235/75r16s are 29.9" in diameter

i wouldn't worry about it too much, my tires measure 33" in the rear and 32" in the front. i drive in 4hi quite a bit on the road. yours has an open diff in the tcase to allow the difference as mine doesn't.

with a 203 transfer case it is a big no no to run two different size tires it is just like running a different gears in the front and back. If you have to let it be like this for a while just take off your front drive shaft but do not drive around to much like this because you will eventually wear out your transfer case

I'm not going to be running it on the street. It's basically just in and out of the garage for the build up till I find some decent tires. I only got these because the tires that came on it were different sizes, old, and looked like they came stock in 74.

easy fix....pull the front shaft

Thanks for the help guys. My daily driver is a 98 Ram 4x4 and I didn't really know much about the full time 4x4 Blazer when I bought it. I just bought it because it was a Blazer.
