Which option would be the most economical in the long run (requiring less maintenance, replacement, lower tire cost, etc)?
(A) Keep the 21", and get Michelin Pilot Sport AS4 (I save the cost of changing wheels & buying TPMS sensors)
(B) Change to 19" for the benefits of square setup, more tire options, and more protection from potholes (BTW, what are the pros of 20" over 19"?)
Also, would winter tires be necessary for California ski resorts, which I visit 4 months a year?
Not sure having both summer tires and winter tires and changing them every year is worth the price/hassle.
I also don't have a garage so can't store tires.
