New tire tests conducted to a variety of tire performance acceptance criteria are the norm in the tire industry. Accelerating the tire aging process and then testing the tire in a meaningful way is not commonly done (or when it is done, the methods and results are not published). The important points are that while a roadwheel test puts a lot stresses and strains into the tire it (1) does not reproduce the full range of stresses and strains a tire is subjected to when operating on a vehicle over a variety of terrains and more importantly (2) does not chemically age the tire in a manner that is consistent with actual road-tirevehicle system operating conditions. Another problem with some of the tests proposed for long term roadwheel durability testing are that they test the tire in an overloaded, over-inflated condition, something which is rarely seen under real world actual road-tire-vehicle system operating conditions. It has to be recognized that mechanical stresses and strains ultimately drive tire failure, particularly if chemically aged. Thus it is necessary to combine controlled chemical aging with mechanical inputs through a meaningful indoor wheel test.
