About the 255/40R20 size
Tesla Model Y 20 in Induction size, W/Y rated XL. Foam-lined EV tires (Pilot Sport EV, iON evo AS, ElectricDrive GT) cut noise and protect range; OE is Goodyear Eagle Touring.
The numbers mean: 255 mm section width, sidewall height 40 % of that width, and a 20-inch rim. Overall diameter works out to about 28 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

What is the best 255/40R20 tire?
For most drivers our mid-range pick, the Hankook iON evo AS, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Michelin Pilot Sport EV is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 255/40R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
