Calling 19" Riders??

Keep in mind, upgrading to a larger wheel fitment also allows you greater tire choices in with respect to width. This can have a profound effect on handling.

Well, for the last 7 (colder) months, I've been driving on 17" Michelin Pilot Sport A/S Plus tires, and this week I switched to 19" Michelin Pilot Super Sport tires, and was really expecting a stiffer ride, but was pleasantly surprised to find that the ride was actually BETTER (not as jarring) on the 19s!

I can only attribute this to the construction of the all-season tires being firmer, and the summer tires being much softer.

The lesson here is if you are going to 19s, choose your tires very carefully. If you buy less sophisticated (cheaper) tires, yes, you might not be happy with the ride.

Many Carrera owners who track frequently are having the opposite experience.
They're downsizing to 18,19 from 20,21. Or at least they want to. But bigger brakes on the 991's are throwing a wrench in that. I think bigger tire requirements are just great for tire companies that upcharge millions of dollars for a mere extra inch of rubber. It's sorta like soda cans, hard to find in your local vending machine and gas station mart, it's all the bigger plastic bottles, so for an extra 2 cents of sugar water they can charge you double what ya used to pay.

I meant to say for street applications.
