I feel like a broken record but here goes - please don't put inappropriately sized tires on your Model 3. We've had several documented cases of issues with the Traction Control/ABS/Stability systems due to undersized or oversized tires. The "safe" range is 26" to 26.8" (1.1% max difference from stock options).
If you feel like you need wider tires, step up to 265/30/20's. Of course, then you need wider wheels (9"+) which defeats the whole purpose of your goal regardless. The better option for stock 20" wheels is 245/35/20's.
The trick to curb protection is not hitting the curbs
P.S. If you would like to put rolling cement blocks onto your car and ruin your efficiency, buy "run-flats" (which is a misnomer in itself, and far more aggravation then it is worth IMHO).
