Test Results

Independent comparison tire tests are the best source of data to get tire information from, and the good news is there have been twelve tests which compare both tires directly!

Out of these twelve tests:

  • Goodyear Eagle F1 Asymmetric 5 finished ahead of the Michelin Pilot Sport 4 in five of the tests
  • Michelin Pilot Sport 4 finished ahead of the Goodyear Eagle F1 Asymmetric 5 in six of the tests
  • The Goodyear Eagle F1 Asymmetric 5 and Michelin Pilot Sport 4 drew in one of the tests

While it might look like the Michelin Pilot Sport 4 is better than the Goodyear Eagle F1 Asymmetric 5 purely based on the higher number of test wins, tires are very complicated objects which means where one tire is better than the other can be more important in real world use.

Let's look at how the two tires compare across multiple tire test categories.

First opinions on new Pilot Sport 4

I have today (11/01/16) received some of the first available Pilot Sport 4's in the UK. They are to replace my worn out Goodyear Eagle ASY 2's on the rear of my GAD Tuned C250 Cdi.

I will review again in a few weeks when I have had chance to thoroughly try the tire out, however my initial observations are as follows:

Aesthetic appeal: They look good and sit well on the rims, a pleasant development over the PS3, both in tread pattern and sidewall appearance, without being 'over the top'.

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.
