Has anybody put 235 85 16 tires on. Why or why not.

Do a search...there is a LOT of controversy regarding the possibility of rubbing and blowing out a tire and the possibility of using spacers.

Line haul and hotshot duty.... They work real good for me.

Best mileage i can get out of tires are in that size. ToyoM-55 or Michelin LTX-AT

Never had a blowout, casing separation , and the tires run nice and cool.

Put them on what? A dually or SRW?

Srw
