I'm looking at Toyo -285/70R18 and 18x9 XD Monsters I have a 2.5 lk in front and 1.5 in back block and u bolts. would I have less rubbing with a 4.5 bs or a 5.5 or would the 5.5 be too close to control arms. Trying to keep trimming to a minimum the actual tire is 34.5 x 11.50. Any other suggestions would be great its a 2011 f150 4wd,xlt 373 gears factory 18x7.5
