Most EVs don’t include a spare tyre, but are instead supplied with a canister of sealant and an air compressor.
The videos below explain how to repair a punctured tyre using the sealant and compressor.
If you have a slow leak, caused by a screw or nail in the tyre, you may be able to use the compressor to re-inflate the tyre and have it repaired, without using the sealant. (A new sealant canister costs around $60, and use of the sealant may require the tyre being to be replaced.)
