I've seen really cheap tires with directional arrows pointing both ways. One way for front mounting and the opposite for rear. Usually you can tell by the tread patterns angleing out from the center in V-like patterns. Water dispersal and treadwear are affected. The latter by tread flex. What most people call cupping is wear associated with tread flex. Flex at the treads.
