Britt1, did you try using the tirefit system in your trunk? You don't have a spare, but the tirefit system will inflate your tire and seal most small punctures. Its essentially Fix-a-flat, for wheels with TPM. Manual says fixaflat will damage the monitor, so they give you your own air pump and tirefit system.

Havent used it yet, but I would also think you could use the pump to just add air to your tires, so you don't need to stop at a gas station, just pull over and plug it into your cig. lighter
