The tires on there now are 29.3" tall and thats right about what the 22" setup will be at also (225/75 R16 and 265/35 R22 ) Hopefully that doesnt hurt me too much. I gotta get the RPMs down on the highway.
Lol, this truck is too nice underneath (and 2wd) to be driving around here in the salt and snow....itll be a 3 season truck only. Ill keep my f250 for winter duty.
