Fitted on my BMW X5 with staggered 20 inch rims. First impression was horror. But......due to idiot fitters putting 52psi in , and not balanced correctly. Upon putting pressure correct, and getting rebalanced at a proper tyre fitters, I don't know any difference from my previous Bridgestone Duellers. Or continentals. No problem whatsoever. Not Star rated for BMW X5 but no probs with transfer box ,so must be consistent on diameter. Look good , cheap, and as my X5 chews rears on inner tread making contis etc uneconomical , I think these harder compound half the price will last a lot longer. Most reviewers would know the difference if these were fitted without their knowing. There aren't many awful budget brands nowadays. Some are even the previous compound and tread / mould of big brands with different make on the mould
