Straight up hes not gunna find a toyota p/u on 38"s - 40"s for under 3k, unless it is al lrusted out, and some ghetto ass POS on bald tires, and in the most ragged out condition with a blown motor. Toyotas Tend to hold there value, atleast around here. And you defiantly are not going to find one on 38"s to 40"s for the amoutn your(he/your mom) is wanting to spend, maybe he should get one on 33"s and gradually work his way up to 38"s - 40"s.....
And if he thinks im jealous he can kiss off cause im already on 38"s so i have nothign to be jealous about.
Husky, good luck with the search for the right vehicle for him...
PS: hurry up and supercharge your Explorer!!!
