I have changed my ContiSportContact 5Ps with these. Quite happy so far. The car feels like more responsive and quiter. I have preferred these over SportContact6s purely because of the price advantage but it doesnt feel like a wrong choice so far. The rim protectors, which dont exist on 5Ps, are also nice. I have just painted my rims before installing these and these protectors have already save me from scratching the rims couple of times.

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.
