The stock size is about 33", give or take for each different manufacturer. I think the rear tires will work fine, but you'd probably need to trip some fender liner in the front.

 

Op, check the 35" tire you want to buy in the specs and see if it truly measures to a 35" size. Most tires do not live up to the sidewall measurements. In most cases they are 1"-2" smaller than advertised. TireRack might have the info, or the manufacturer should.

My last Jeep Wrangler TJ came with stock Mixed Matched tires from the dealer and I didn't catch it until I pulled into Discount Tire. The rep pointed it out that I had matching fronts in a different size than the rears. I knew I was buying tires lol. I did not like the way it rode, so we looked at a few sets. I went with the General Grabbers and in a 31" size. It was a huge improvement over my who knows what I had on the Jeep when I bought it... Met up with some friends and a few days later and one was looking over the tires and he said did you put a tape measure to the tire to see the real size? I said No. He pulls out the tape measure and it was a 29"tire not a 31" which the tire side wall indicated.
