The Michelin X Radials were option on the Jimmy as the OEM tires when the Jimmy was ordered. 235/70-15 and the OEM Tire size was 205/70-15. You may like the BF Goodrich TA (performance all seasonal) I my self is running 255/65-15 on my jimmy, yes the tire is wider but the hight stay's the same and you get more mileage out of the tire. Just have to be careful you don't go to fast in the rain or snow, they're prone to hydroplane. I have not had that problem or have gotten stuck in the snow, but i do most of my driving on the hyway. With your 205/70-15 your going to want to 245/60-15 or the 235/60-15 so your speedometer would not be affected. Good luck and surprised that the Kuhmo's did not work out for you. There the second best seller tires for the jimmy, but then again the price is good too. Just make sure what ever tire you get, your running them no less then 32PSI.
