If Wanli performance tires look like they are a copy of some better known brand performance tires, are they just as good as long as they have the same speed rating? Are the speed ratings the product of official testing or are they assigned by the manufacturer?
Is there good rubber and bad rubber?
Are treadwear numbers the product of official testing or are they assigned by the manufacturer? Is the treadwear rating a reasonable performance indicator -- i.e., the lower the stickier or might some tires with treadwear ratings over, say, 300, be very sticky?
