I agree with you 100% (except I find bridgestones shit TBH)
but the Ku31's are a very good tyre. Only downside I had with mine (215 35 18) was the road noise which was way above what any tyre should have. Otherwise grip levels in all weather conditions was very nice.
Having said that though i have driven cars with the lower graded kuhmos and found them to be rubbish.
