245/35/19's are the same size as the trd. 245/35/19's will not scrub as they are 2.83mm smaller in diameter than 245/35/20's. i have these and have never scrubbed. i know lots of people on pedders that have these and never scrub. and the wheel/tire being outside the guard will become less when u lower it as it has independant front suspension, meaning the lower it goes the more camber is on them. this also means when u go over bumps the wheel goes up, the top of the wheel also goes in aswell therefor not hitting the guards. i really like the wheel tho!!!!! look even better when u lower it :D
