Is anyone else running "ST" radial tires on your Advanced Design trucks? I have the original suspension and engine, don't drive over 45 MPH and no fast cornering. I've been told these shouldn't be run on "passenger cars" as they aren't DOT approved. They must be better than the original bias ply that came on the vehicle originally. If it's a real safety concern, I'll buy the 215 85R 15 radial ...just don't know where to buy them. For reference, this is what I bought: Rims and hub caps from Jim Carter Trucks Rims: MST150 steel 15x5 6 lug 5.5 bolt pattern Chrome Hub Caps: MST159 Tires from Tires-easy.com ST205/90R -15 Radial Thanks!
