Why tires will feather from folding over the tread blocks...even high way
tread. As they too have tread blocks or edges that fold over to feather while
braking that hard
gee-buz Ben... "feathering" of the tires is due to improper toe-in, and/or worn out bushings causing wheel alignment to shift as the vehicle moves down the road, nothing to do with braking.
What your showing and talking about is called "CUPPING" or "SCALLOPING", which is normal wear for hard acceleration and braking.
Too bad ole Ben has me blocked.... sad because there are so many here that believe everything he says, sure talks a good talk, but I gotta call BS when I see it... like how hes developing a programmable control system for "his" gas compressor... sorry Ben but those panels have been around for 30+ years!
