Good grip on dry, but wet grip is not so good. Very inexpensive and last long. A bit noisy when worn.

These tires were the cheapest options for the Z4 with the staggered (225/255 front/rear) size and the dealer where the vehicle was purchased from put them on in 2010 ($90 front, $110 rear). For regular day to day driving they are a decent tire although they are noisy. However, once the smallest amount of rain hits the pavement they are outright DANGEROUS. The slightest throttle input on intersections from a stop gets the back-end out atleast 10-15cm before you can realize and correct. Although they are supposed to be an all season tire, there is no way these tires would take even the smallest amount of snow in southern Ontario. The Z4 is parked in the winter so I have not had a chance to test them out in the snow. It is safe to say that I would not be getting them again, especially since there are many options that are only slightly more expensive. You get what you pay for.

Had a sey of these after needing 4 tires. Replacements for my Bridgestone Potenza's were £260 per tire. The AS1's were £93.
Although the bridgestones were a better tire, they were not £160+ better and I would definately but these again.

budget price but better than most premium tire brands excellent rim protectors

The worst tires we had today, not advise. They are good for the variety of measures and accessible only by price
