Thread: Tyres scalloping (cupping) Causes?

It may be worth consulting Toyo.

Still think its worth borrowing a set of tyres from a mate to do an elimination test. can't hurt and you get to drink beer while swapping the tyres over. As for tyre wear. I am an advocate for BFG. one set i had were fubar in less than 50,000 kms of not so harsh driving. All other BFGs i've clocked +70,000 kms and most of that was beating on them most weekends in low range and the sandstone around sydney. sometimes you get Friday before a long weekend QC

Thanks MLD. i thought about the tyres themselves being the problem but it would seem odd for all 5 tyres to be affected. I can understand a random tyre but 5? I take your point though about MTs or aggressive tread tyres being prone to scalloping. I hadn't thought about that because MTs are outside my orbit - I've never taken any notice of them. Regarding your suggestion of a tyre swapperoo, even if I had access to another set, with family responsibilities I don't really have the time. If the mechanic doesn't come up with any smoking guns next Tuesday i will get in touch with Toyo. The only possible cause I'm eliminating is wheel alignment because all the tyres seem evenly worn across the tread. Appreciate your interest. Cheers.
