I had 2 new tyres fitted recently and on balancing you could see one of the wheels was badly buckled. Took it to these guys and they explained the procedure of removing the tyre and heating up the wheel so they can reshape. They also mentioned the possibility of the wheel cracking, apparently it happens 1 in 10 but they repair that with welding if it does occur. Mine was done while I waited and didn’t crack
