am i going to have issues running that setup? i blew a front right tire and cant buy new tires for a bit. I found some used pirelli's to put on front but they are 235 and my currents are 245. let me know, im going to put these on at lunch.

Thanks for info.

Yes, your t-case will hate you. There is a height difference on those sizes. Don't risk it and use the same tire size on all 4.

also, i thought the 235 is the width of the tire not the heighth? isnt the 45 the heighth? which is staying the same, i thought it to be just a slightly thinner tire in the front.

235 is the width... 45 the height which = a % of the tire's width. The numbers work together to provide the overall diameter.

The 235's are 25.3" and the 245's 25.7" which can be enough to cause issues. The minimal performance/visual difference between them isn't worth the potential mechanical issues.

thank you for a clear response. although its worth noting, i am not going for visual effect or performance gain, i am simply trying to get off my damn donut lol until i can buy a new set and the tire shop near me has two 235 45 that i could put on front. i wanted to see if i could pull it off, no aggressive driving, just 10 mile commute to work for a couple of weeks.

you can spend a couple hundred on tires or a few thousand for a t-case

it doens't take much difference to fry the t-case

you could probably get away by over inflating the front but it is recommended to have the front and rears the same sizes.

This is pretty handy in a situation like this....keep the heights about the same.
