A guy that could not hook his NA Hon-duh gave me these tires with only four passes on them. I had to get a set of rims to allow clearance for these puppies. They are 22x9.5x13 M & H drag slicks. When off of the rims they measured out to a 11.5 inch side wall, 10.75 inch when mounted on 7 inch wide rims...that are 4 inches of backspace (MINUS 35mm offset!) The tires are 4.5 lbs heavier than the Hoosier 20.5x7x13s eash side and they slowed the car by only .10......I'll save them for cold days when my very old Hoosiers no longer hook....at least they make my car LOOK fast! The Hon-duh went to 26 inch slicks on 15 inch rims and went from low 11s to mid 9s!
