aftermarket 16 in rims also bfg tire size?

ok so i was planning on getting new tires and rims for the taco. went to 4 wheel parts store today and got a qoute. there is only 2 problems. 1st i wanted to get bfg AT 265 75 16 D rating. everywhere i look i can only find them in the E rating. 4 wheel parts has them in the D rating. my question is are these discontinued in the D rating?? the 2nd problem is i was thinking about getting black american racing atx mojave teflon rims 16 in diameter. at 4 wheel parts the said i would have to go to a 17 in rims or else the brake calipers will rub? is this true?? thanks

 

No they won't rub. Only the 15" wheels will rub

:edit: As for the BFG being discontinued, i'm not sure. Try looking online at http://www.tirerack.com and http://www.Tire.com
