18" wheel on model Y

of course it's safe; done properly.
however, you have to pay attention to clearances.
the wheels have to clear the brake calipers and have the proper offsets to the tires clear the suspension bits and don't stick out of the wheel wells.
the tires have to be the proper diameter so as to clear the steering knuckles in the front, and proper width to clear the suspension bits.
there's plenty of info here on these threads.
That would have to include any stick-on wheel weights.
On my 2010 Honda Fit, I had to buy new 17” wheels because the wheel weights on 16” that I had would not clear the upgraded brake calipers.
Sure, you can use clip-on weights… but alloy wheels and clip ons are usually a “no” for a couple of reasons, mostly aesthetics.

18" tires are technically bigger than 19". The outside diameter remains the same however the inside diameter is smaller resulting in a higher sidewall. There are more choices to be had in 18" sizes and in general they are also cheaper plus having more sidewall they give a slightly better ride compared to the 19s. No issues at all going from 19 to 18.
as example:
I have some off-road requirements that the 19" OEM tires on a MYLR would fail (or be higher suspect to marooning me).
I acquired some M3 18" Aero wheels and put BFG Trail-Terrain tires on them for my excursions.
Slightly taller than OEM and more sidewall. They actually ride smoother and sound no worse than OEM.
But for the general public, the pursuit of a smoother ride might be sufficient to explore a smaller wheel.
However, there are few 18" wheels that will clear the MYLR brake calipers and fewer still clearing the larger MYP calipers.
So it takes some insight and knowledge to achieve.
You guys don't have a dealer in Toronto, Ontario, Canada do you?1,000+ 18" Model Y Wheel and Tire Packages Sold. Fits all Model Y variant including Performance.
Thanks.
wheels won't make much difference, it's the tires, and even those aren't going to be hugely different.
Buy tires that make sense for your need and fit your budget.
no
unless you believe wheels have more influence than the car body
wheels contribute an extremely low percentage of overall drag.
2-3% differential between wheel types.
wheels however amount to a vanishingly small drag percentage compared to the overall body.
I'm afraid modern marketing doesn't distinguish such.
they're trying to convince you to buy their wheels rather than someone else's.
