spare tire question

[Plucki]

I have a model 3 performance with the standard 20" rim/tires. I also have 18" rims/tires for winter driving. Can I use the 18" rims/tires as a spare tire on a long road trip? If so how long can i drive with mismatch rim sizes?

I dont know if the factory 18s fit... I have never looked into that. I know that factory 19s work, as I have had those used by roadside assistance when I had a flat tire (and I have a model 3 performance with factory 20s).

Tow companies that tesla contracts with, that carry spare tires for model 3, only carry the 19s and use those as a loaner tire no matter what size tire you have. If you have 18s, 19s, or factory 20s, the spare tire the tow trucks use is the factory 19s. I was worried about a tire with a difference size being on there, and tesla roadside told me it was fine. They were even willing to send me that in an email, when I requested it.

Someone else will need to let you know if factory 18s fit. though.

Thanks. I think you answered my question about driving with different rim sizes. The 18s I have are not the factory 18s, they are after market 18s made for the performance model 3.

Presumably the closer in size the overall dimension, and the closer in weight, the less likely to be an issue.

I built a full sized spare for this reason.
