Thank you Topless!
Excellent point about the different tire compounds. I will make sure not mix-and-match tires.
I am planning to use the donated all season tires for winter (light) and regular street driving...and keep the Toyo Summer tires for autocross/DE uses only.
Just need to find two lightly used Michelin Pilot Sport A/S 205/50/17 or 225/45/17 for the fronts now
