I had a flat (screw in tire) at 800 miles. Luckily it was in my garage. I didn't use the factory tire kit, I'm sure Dodge wants a fortune to replace it once it's used. I just plugged it myself & bought a new tire. It was about a month before my run at the airstrip & I wasn't taking any chances on a repaired tire, professional or not.

It's not too bad. The thing operates as a reusable air compressor with the one-time use sealant canister. You can buy canister refills for $45.
