You would not put a pair of wing tips on a sprinter.
All the components in your expensive sports car are there to make your tires work.
Want a quicker lap time? The biggest bang for the buck is improving your tires.
Why risk thousands of dollars in body shop bills trying to get another hundred miles out of worn tires?
When the longitudinal grooves that channel water begin to disappear, it is time to replace the tires.
The wear bars indicate an absolute minimum tread depth for wear, but tires should be replaced before they reach this point.
On some sports cars, the rear tires may wear at double the rate of front tires.
Previous passenger car owners may expect thirty or forty thousand miles of wear. Sports cars are incapable of those figures unless their performance is severely compromised.
Your right foot on the accelerator is related to the amount of tire wear you can expect.
The sticky cup tires may last 4,000 miles if you’re not too aggressive.
The newer Cup tires will last longer but are still limited on mileage. They still suck in the rain.
Negative camber (the top of the tire tilted in); the inside edge will wear quicker especially when driving straight.
Check the whole tire not just what you can see from a quick glance at the outside of the tire.
Temperatures under 45 degrees Fahrenheit will pretty much render performance tires ineffective.
As the rubber gets colder, it gets harder and less sticky.
Winter tires are horrible in warm weather performance situations.
All-weather tires are neither fish nor fowl. As a rule, they are not particularly good in either extreme. They are adequate for both.
Michelin and Bridgestone make performance all weather tires that both perform and wear well, making great commuter tires (lasting longer than performance tires).
The “N” designation means that Porsche has tested and approved this tire for use with your Porsche.
Porsche has tested and approved “N” rated tires for all around results: dry handling, wet handling, stopping distance wet and dry, noise, wear, unsprung weight, and feel. Choose wisely if deviating from “N” rated tires.
Never mix tires; go with the same model and generation as on your Porsche.
Generation can be determined by the number after the “N”. N0, N1, N2…
Be within 30% of treadwear when replacing less than a set of 4. If your tires are 50% worn, you should replace the set rather than have 3 tires at 50% and one at 100%. Use may be considered. Commuting may be an exception, but in any type of performance application, tread should be more consistent.
Never let performance go past 6 years of stamped production date. The date will be week/year… 34/19 means produced in the 33rd week of 2019.
Never let Cup tires (higher performance) go beyond 4 years. Think of a basketball player, older rubber on shoes will get harder and start to slip.
New tires are much cheaper than a trip to the body shop.
