Quick background:
I had Tesla’s factory installed tires for the 21s from date of purchase. After about 13k miles, they were ran down to about 20% life before swapping them.
Quick fallow up:
I decided to purchase the cheapest possible tires I could find which were the Nankang’s for $562 tax and shipping included with a 40k mile warranty. (what were you thinking?! Got it) to see how something at a lesser price point would compare.
As of today, I’ve driven 31k miles on my car and in which 18k of those miles are on those “cheap” tires.
I just pulled a picture that was taken at 2000 miles and a picture I just took as of today. The first pic is at 2k miles, 2nd pic is at 18k miles. As you can see, there is plenty of tread remaining even after 18k I would say around 70% if I were to guess based on the “penny test” to me, that’s impressive and may actually live up to Nankangs claim for them to include a 40k mile warranty.
If comparing to Tesla’s included high dollar Continentals far as life goes.. incomparable. I’m a heavy and harsh driver and those Continentals showed just that after 13k. To the point it was completely unsafe to drive on. The Nankangs on the other hand, 18k and roughly 70% is great especially for a Tesla and my driving style.
Read back at my original post Those “cheap tires” review for a more detail review. I still stand by my first review and still believe these perform more like a all season vs a performance tire that these are market as.
Lastly, as far as stopping distance goes. I don’t have the right tools or Environment To properly test that category like most. But, based on real world driving, stopping on a dime has never been an issue and doesn’t feel any less/worst then any other car I own. So after 7 months, 18k later, and ~70% life remaining, would still recommend these and buy again. The price point, performance (all season) life expectancy, and warranty is a lot of value for under $600 all in.
