Tyre review for Michelin Pilot Sport 4 S 255/30R19 91Y XL
I've fitted my BMW E89 Z4 3.0 (manual) with Michelin Pilot Sport 4S tyres and they're awesome. Out of all my comparisons, I've noticed the biggest difference in feel, traction, handling, comfort, and road noise in comparison to the standard BMW Bridgestone Potenza tyres, especially while driving on the 19'' lightweight alloys. This costs more than the Bridgestones and other non-runflat options, but you can tell how much more performance Michelins have over the rest. You won't regret this upgrade.
