what size tires

i just bought some 17's and i need to know if a 235/40 will work i can get three for free. my truck is bagged.

That is a fairly wide tire for a b series especially the fronts....I would say yes for the back if the offset is right, but the fronts...it might be tight.

thanks its a set of new silverados

I ran 225 - 50 - 15's on all 4 corners no problems

well i bought some 215/45 for the front and 235/45 for the rear.

i think your gonna have probs with em. I know the eskies have trouble tucking under 2wd metal with 215 45s on the rear. but 205 40s dont fit the wheel. not wide enough and look retarded being smaller then the width of the wheel.
