Good rubber for the track, wear-resistant. Operation on Opel Antara. I read a lot of reviews, including negative ones. But over 70,000 runs, wear is about 50%. I like. Maybe in other sizes rubber so Sibe. But in my size 225/70 R 16 103 h is great. I did not experience any problems or discomfort. Sidewall with index 103 is normal. Took 7000 per wheel. In this size. A slightly smaller size with an index of 98 cost 5700. You can safely take it for the track. My production is China.
