I've been buying tires from A.I.M. on Dennison in Markham for 25 years. Phil or Max, the owners know their tires inside out and have never steered me wrong.
Recently I bought new Continentals for the Jag on their assurance. I am very happy with them. It turns out F-types are extremely finicky as to what tires work best for them, and they were able to give me the right ones. They also had the best price of 5 shops I checked
