    you could probably fit them but you may need to trim some more because youll probably rub at full flex

    The irocs work very well. I dont have the radials but Im sure they will do well also. I have the 39.5s on my 1ton with a 6 inch suspension lift and under full flex I would hit fender for sure if they werent trimmed.Oh, and from what Ive seen they dont like the highway very much.

    i have had many different tire brands from dunflop to bfg to goodyear mtr and now i have procomp xtr and in my opinion the best tire is the good year mtr....i would like to know more about how the irocs ride on the street becasue my blazer is my daily driver and i know they have to ride better that the piece of crap tires i have on there now...they cause my truck to have a death wabble....and i have spent alot of money replaceing parts on my front end thinking it was something else

    What brand of crap is on there now? I hadn't thought of the tires being part of DW.

    i have a set of the 37x13.50x15 procomp xrt i think it has to do with the side walls on the tires and the air pressure i used
