In this article we will be looking at independent tire test data, and real world driver reviews of the Bridgestone Potenza Sport and the Pirelli P Zero PZ4 to find out which tire is best for your own driving.
The good news is that both the Bridgestone Potenza Sport and Pirelli P Zero PZ4 are Max Performance Summer tires designed to be fitted to Passenger Cars, which means comparing the two tires is relatively simple.
Both tires are hugely popular in the market place with drivers, and both have been featured in independent tire tests.
Independent comparison tire tests are the best source of data to get tire information from, and the good news is there have been nine tests which compare both tires directly!
Out of these nine tests:
While it might look like the Bridgestone Potenza Sport is better than the Pirelli P Zero PZ4 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.
Looking at data from eight tire tests, the Bridgestone Potenza Sport was better during four dry braking tests. On average the Bridgestone Potenza Sport stopped the vehicle in 0.21% less distance than the Pirelli P Zero PZ4.

Overall Winner: Bridgestone Potenza Sport
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.
