>vulanisation and retreading bald tires

There's a reason those are largely gone - retreaded tires have been the cause of many accidents and blowouts over the years...

it's gone for regular pedestrian vehicles mostly, but it's still fairly common in the U.S. to see retread shops near any semi-truck hub areas.

lots of retreads on tractors and trailers and buses. the only tires that are required to be virgin/non retread are the steerers on buses
