Hello Jay,
I am thinking of getting the 21s on the right for my build. What is the difference between all season runflats and the performance runflats.
Thanks.
Anyone can answer your question.

All season run flats provide all season traction all year round. Good enough for snow and limited ice traction.

Performance run flats provide increased handling response and traction, particularly in wet and dry conditions. The compound becomes less compliant when temps drop below 40 degrees and are literally hockey pucks on ice in snow and ice conditions. You'll need a set of snow tires for the winter.

Your tire options will be extremely limited with 21"
