I have a 05 Supercrew FX4 with a 2in leveling kit and the 18in stock aluminum rims that I really like...right now I have 285-65-18. How bigger tire can I go WITHOUT rubbing or any problems.

I have a 295/65R18 on my 06 FX4 with level and i dont rub, its roughly a 33" tire

I've seen guys run 35 12.50 18 with a 2" with little or no rub

I'd go with the 305x65x18 BFG TA/KO 34x12

With a 2.5 level kit I can absolutley tell you a 35 inch tire rubs, I have 34.3 and get a little rub when going in to or out of driveways... I tried 35 inch test fit and they rubbed when the steering wheel was cranked... New tires I dont want to wear off rubbing against my new truck... I did a 295X70R18 nitto tire no rub, unless going in to and out of driveways while turning... Then I get a little rub not bad but sucks with new tires I can hear the dollars rubbing away... So I am careful not to go fast when going over bumps fast while turning...
