will they fit?

I just bought a 92 Explorer XLT and want to get larger tires and a lift kit, but would like to get the tires first. I am looking at getting Goodyear Wrangler AT/S', 33x12.5 on a 15 inch rim. For one thing, will these fit on my factory rims, as i would like to keep them? I was told the 31x10.5 would, how about 32x11.5?. Second would the 33x12.5's fit without a lift, how about the 31x10.5's, 32x11.5's?

Hi, well the biggest that i have ever heard can fit under a stock exp is 31/9.50 with stock rims(stock rims are 7.5" wide) if you would like to go as big as 33/12.50 like i have on my 91 sport you will need a 3" body lift and $160 for knew generic black,white,or chrome steel wheels. and a small amount of fender trimming is needed along with the inner fender on the inside of the front fender. so i hope that answers your Q's good luck.
