In this article we will be looking at independent tyre test data, and real world driver reviews of the Bridgestone Potenza Sport and the Pirelli P Zero PZ4 to find out which tyre 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 tyres designed to be fitted to Passenger Cars, which means comparing the two tyres is relatively simple.
Both tyres are hugely popular in the market place with drivers, and both have been featured in independent tyre tests.
Independent comparison tyre tests are the best source of data to get tyre information from, and the good news is there have been nine tests which compare both tyres 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, tyres are very complicated objects which means where one tyre is better than the other can be more important in real world use.
Let's look at how the two tyres compare across multiple tyre test categories.
Looking at data from eight tyre 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 tyre industry testing best practices. This means we are only comparing tests which have had both tyres in the same test.
Why is this important? Tyre 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 tyre test external condition changes are calculated into the overall results, but it is not possible to calculate this between tyre tests performed on different days or at different locations.
As a result you will see other tests on Tyre 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 tyre comparison, Tyre Reviews doesn't.
