Ok, Wisconsin, so BIG fan of Winter Only tires. Current choice was a rec from my Canadian Friends, the Nokian R3s and R3 SUV.
I ALWAYS try to go as narrow as possible while keeping overall diameter the same as stock.
My X has 265 20s front and 275 20s rear. Way too wide for best snow performance. Tesla doesn't sell the X winter package in 19s anymore, but it is still an option on the tough screen, so the car would know I went non-staggered.
Want to minimize range loss, and a 19 narrower tire is also better, but not expecting the world, any bit helps.
I found a set of 2020 S 19" Tempest rims, the ones with the aero cover. They are 8.5" wide, where stock is X 9 and 9.5. 35mm offset matches the 20s. S and X used same brakes so should fit. (Looking at the Tempest over the S Slipstream that cosmetically matches what is on the X now, because the Tempests are 8.5" wide with a 35mm offset where the S slipstreams are 8" with 40mm offset. So the Tempest will match the location in the wheel well nicely.)
As narrow as can go on that rim is a 245. At 55 aspect ratio, diameter comes in right in the middle of the stock 265s and 275s, so good to go. Load on the Hakkas is 107XL, stock is 108XL and 110XL, but looking at the ratings, and curb weight, each tire has 253 lbs safety factor over stock (rears, fronts even better)
Only concern, and I know people will tell me not to do it, is the S rim has an unpublished load capacity. IF I were to load the X to max, I MAY be over the wieght of the rim. (S curb 4886, X curb 5630. Of per tire = 186 LBS. About 10% of assumed rim load). I have a hard time believing a stock rim doesn't have a 10% safety factor. Some after market P.O.S. from who knows where, maybe. Plus, I don't ever see putting that much in the X.
The stock rims are NOT light at close to 30-35 LBS. Aftermarket that are rated are as low as 23LBS, so the extra mass should make the stock rim strong.
Just wish we knew the official ratings on the S rims.
