So i just blew out a tire and went to a salvage yard to get a new tire and wheel because i obliterated the wheel along with the tire. Anyways my three other tires are p235/70R15 and i found a p215/70R15 in really great condition. I picked it up regardless because it was so cheap but I'm just curious if i use that tire with the rest of them will it have any adverse affects on wear/mileage/safety/etc? Kinda in a bind so any help would be greatly appreciated.

 

if you put it on ..make sure its on the front and dont use your 4x4 becuse it can ruin your rear end (if its in the back) or if its in the front and use your 4x4 can effect the transfer-case as well

think of it like this....at 60 mph..your 215 is spinning faster then a 235 but....you rearend (or Tcase) cant compensate for that much of a difference in wheel speed
as long as your 215 is in front and not in 4x4...youll be fine other then having a decent lean in your ride ..id use that as a temp...i wouldnt say good enough and leave it otherwise that 215 is goina wear faster then the rest becuse theres more weight on it and the inside of the other side tire might wear alittle more too...but as a short term fix..youll be ok
