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 tires 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

Footnote

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

Why is this important? Tire 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 tire test external condition changes are calculated into the overall results, but it is not possible to calculate this between tire tests performed on different days or at different locations.

As a result you will see other tests on Tire 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 tire comparison, Tire Reviews doesn't.
