I wanted to share my initial impressions and first 1,000 miles on an oversized set of 235/60R18 tires on the Model Y.
Ride quality has been overall improved. It’s not Mercedes S-class level of plush or quiet, but it’s much more compliant and muted than before. There’s a clear “pang” sound at highway speeds on big bumps—similar to an overinflated basketball being thrown down. Other than this sound, everything else is more quiet. I’m very happy with the ride. The extra 0.6” ride height is noticeable when getting in and out, but it’s neither a pro or a con.
Handling is as normal as it ever was for me. I do not drive aggressively since I have Tesla insurance, and I avoid hard turns, braking. I do, however, mash on the accelerator completely and frequently which feels unchanged. It has thunderstormed only once, and the tires have not lost traction once.
Looks are subjective, but these tires definitely look goofy. The aftermarket aero covers conceal the 18” rims well enough.
Efficiency. My TeslaMate efficiency has gone down by 1.3% overall, but the tires are 4% bigger (meaning miles are under-reported by the same amount), so instead of losing any efficiency, I’ve gained 2.7%~.
Speedometer is 1.5% lower than actual. When I set cruise control at 75, GPS shows 76-77. The tires are 4% larger in diameter compared to stock, so that tells me the speedometer in a stock setup is underreporting by ~3%.
I’d do it again 100%!
