I'm on Tire Rack's site looking at the Revo AT2 and the Hankook RF10, and i notice two different prices for the same size for each tire. they both show up when i search for suitable replacements for my '00 LX. the difference is that the cheaper one is a P265/75R16, while the more expensive one is the LT265/75R16. i assume the LT is a heavier-duty tire. so is the 100 considered a P, an LT, or will either work?
