Swapping tires from PUP 21" Uberturbines to 20" Inductions

[iancluna]

Just picked up my Model Y a few weeks ago, and I wanted the 20" induction wheels instead of the Uberturbines so I bought a new set of Inductions from craigslist. I wanted to go square instead of the staggered setup, and also go smaller to avoid curb rash and get a smoother ride.

I brought the inductions to America's tires and wanted to get 255/40 20 (Michelin sport 4s tires) tires to swap with my uberturbines, but they recommended that I get 255 /45 R20 105Y XL BSW (Michelin Pilot Sport 4 SUV tires) because of load requirements...? I am not too familiar with tire sizes but is this a good way to go?

Any help would be much appreciated!

The standard size Pilot sport 4s are rated at 101Y / XL, which is a sufficient load rating for the Model Y.
