hello Centaurus

do you have any reference material to support the suggestion of increased liklihood of tyre failure with the higher Vr? Having done a fair bit of research into tyre dynamics at university I am not sure where that comes from. It isnt supported from anything I remeber from those days and would be interested to see the reasons for it. Marginally increased wear I could understand but if you remain within the stated performance envelope of the tyre I dont understand what is failing.

honest question, not fishing..
