I have 30x10.5x15 tires on my Jeep Wrangler TJ 2004. I need new tires,have a deal on 31x11x15. Will they fit without at a lift?
Yes they will fit but you may have a little trouble with them rubbing now and then.
You can fit 31s in there, but if you offroad you will stuff the tires in the wheelwells. If you want to go bigger, consider getting a $200 Budget Boost, which will give you a little more suspension clearance. The 31s will then clear easily, and you may be able to put 32s under there (but again you'll stuff them when you offroad). Also keep in mind the strength of your axle and the size of your engine. If you have a 2.5L engine, the bigger tires will cost you in power and highway speed.
two different tire sizes all together, you might have a hell of a time trying to get the tire which is a little bigger on a rim meant for a 10.5, but there have been times that i've seen people use those size tires on stock size wheels. full turns yeah it'll do it, might rub a little on the fenders, wide tires of that nature are great for snow, most if not all off road style tires work great in snowyou might as well to be on a safe side run the standard ones you got on there and buy sizes of that type.
