Well these sound like a good way to go, plus I can get a good deal on them. About 145 for P rating and about 185 for the LT.
I would think the LT would be somewhat harsher on the road- is that safe to say? Since I really don’t do much rocky 4wd excursions with my 4Runner, I’ll prolly go with the P rated tire.
They are firmer riding than the OEM Dunlops, but not horribly so. Just be aware that the P-rated tire has a slightly milder tread pattern, and shallower tread depth.
If I didn't need/want the extra durability of the LT tire for 4wd trails, I'd go with the P-rated version.
