Tech crew said nothing at 3 different autocrosses that I ran with my
175/60R13's on wire wheels. Pretty sure the wheels are 4.5" wide. Been
running them on the street for 6 years now. No uneven tire wear. Just a
bitch to mount and dismount for flats. Love that lifetime Les Shwab flat
repair and balance!

> Sorry for not being specific. Direct Tire in Massachusetts, and the
national chains the Tire Rack, Discount Tires and NTB advise that a 145 or
155 tire should be used with a 4 inch wide wheel. Direct Tire warns not to
exceed a 165 on a 4 inch. 175s are fine on 5 inch rims, but they will
typically interfere with the body work which is also dangerous.

and 4 inch rims slice, deflate, disintegrate and roll over. I have also
seen accelerated, uneven wear across the tread. I do not believe the 3.5 is
allowed in road racing any longer, but I may be wrong. Based on my own
observations and the advice of the various retailers, I would not put a 175
on a 4 inch rim.
