In this article we will be looking at independent tire test data, and real world driver reviews of the Dunlop SportMaxx RT 2 and the Giti GitiSportS2 to find out which tire is best for your own driving.
There are a few basic differences between the two tires. The Dunlop SportMaxx RT 2 is an Max-Performance Summer tire designed to be fitted to Passenger-Cars, and the Giti GitiSportS2 is an Ultra-High-Performance Summer tire designed to be fitted to Passenger-Cars
Independent comparison tire tests are the best source of data to get tire information from, and the good news is there have been five tests which compare both tires directly!
Out of these five tests:
While it might look like the Dunlop SportMaxx RT 2 is better than the Giti GitiSportS2 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.

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.
