I have had these on the rear of my XFR for a few months now, it has the optional "R-S" size of 295/30/20. They get a hard life on a heavy >500bhp RWD car with quite relaxed electronics, and these are by far the best tyres I have used on the rear of an XFR - various models of which have been my daily driver for 6.5 years now (about 90k miles covered in that time). Traction is superb in wet and dry conditions, and resistance to aquaplaning has been good as well. It is slightly concerning they come with

I was very surprised by the comfort of the new tyres. My previous tyres were the fk510 and they were hard as hell, felt every crack in the road. The handling in dry and wet conditions are very good, and the cars feels sporty and good in rhe tight curves. Hope they will last as long as fk510 (around 35k km)

Footnote

This page has been developed using tyre industry testing best practices. This means we are only comparing tests which have had both tyres in the same test.

Why is this important? Tyre testing is heavily affected by things like surface grip levels and surface temperature, which means you can only compare values from the same day. During a tyre test external condition changes are calculated into the overall results, but it is not possible to calculate this between tyre tests performed on different days or at different locations.

As a result you will see other tests on Tyre Reviews which feature both the %s and %s, but as they weren't conducted on the same day, the results are not comparable.

Lots of other websites do this sort of tyre comparison, Tyre Reviews doesn't.
