Looking for more tire comparisons? Here are other direct comparisons involving these tires:
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.
