I am nearing 35k miles on my MS with stock 19" Michelin tires from Dec 2013, and am now starting to consider change of tires. With no experience of ever buying and changing tires on a car before, I have some very basic questions. Which tires to buy? Summer? All Season? Quiet? Performance? There is already a lot of discussion about this on the forums, and I have been following most of them for a while. So this question is already close to "answered" for me, and I have more or less settled for Pirelli Cinturato P7 All Season Plus. But I would appreciate any additional inputs too. Where to buy from? Online? Aspects to consider other than price? Warranty? Also, how do they know how much the tire has been used to validate warranty? Any catch when a tire is on sale? How to install? Does the seller also install the tires? Do I bring the tires to a Tesla SC to install? How much does it cost? Any other considerations? What happens to my old tires? I didn't just want to go by what the internet says, suspecting some aspects might be different in case of Tesla.
