Is it still a speed rated tire?
Probably not. In general tires that state reproveable on the sidewall are regrooved long before they are completely bald. Semi-truck tires the new grooves are cut about 1/4" possibly a little more. car tires don't have a very think tread belt on them so maybe 1/8"Quote:
