I would just air them up to 35 ft lbs front and rear like the OEM tires and see how that works out for you. If you want you can do the chalk test to make sure the entire tread width of the tire is contacting the pavement. This way you would know if you need more air in them or if you have to much. But for that size and brand tire you will be fine with just filling them to 35 ft lbs and calling it a day. Im running 265/70R17 Goodyear Wrangler MT/R's with Kevlar at 35 ft lbs with no problems. This is my second set and the first ones wore perfect, besides the little alignment issue I had.
