We own a 2000 Mercedes-Benz SLK 2.3K that has just completed 32,000 miles on its original tyres. We need to replace two rear tyres and I have been searching for tyre reviews online. Most review sites cover issues such as grip in wet or dry conditions, cornering and comfort, but nowhere can I find mention of durability. Given that driving style will affect this, surely there are two issues that are not covered: the depth of the tread of the new tyre and the composition of the tyre itself. Why are these two aspects not reviewed?
