I'm assuming the wheels are 7 inches wide. Do you have any photos of the face? I'm trying to find the best tires for a rig that came with H-70/15's that had a very square edge. They were 9 inches wide so I'm looking at a 255/70/15. The last tires were Milestar which had a good edge, but they...
I'm looking at Milestar 255/70/15 tires (14 much the same) as they look a lot like Goodyear Polyglass tires. Looking for that square edge. Coopers do too, BF Goodrich don't
