Anybody ever have a flat in their Hellcat yet, and have to use the factory inflator kit? Just wondering how well they work and how reliable they may be. I am old school and still did not like the fact that I'm driving around with no actual spare tire. I have heard they may work for a very small puncture, but anything too large and you are SOL. Also, if you had no cell reception to call for help, with the SOS button in the mirror work? I had heard that runs off of GPS. Thanks!

So, I can tell you that the inflator kit works just like a normal can of fix-o-flat for the most part. It's designed primarily to get you off the road and at least somewhere safe (within 20-30 miles max). After that, I really don't recommend testing it beyond that. Some may feel otherwise, but I just don't recommend it with these cars... a 150 hp Honda....different story.

As for the SOS button, it does run off GPS and really should be able to get signal out to anywhere short of being in a tunnel or under some kind of parking structure (even then it may still get out).

The only suggestion I would recommend is consider buying a spare rim/used rim and putting a tire on it just in case to leave in your garage.

Buy a plug kit to it might save you if the hole is to big,

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.

Thanks so much for all the responses. Question; if I were to get an actual regular spare tire, would it have to be identical to the factory tires and wheels that are on it currently? Car is bone stock.

This one has been talked about a bunch on this forum.
Modern Spare

If you have the 6 piston brembos on front and get a flat there, you'll either have to use a spacer (available with kit above) or take a wheel from the rear and put the spare on the rear.

Or you could just do what I'm planning: getting wider wheels in the back and using one of the stock ones as a spare when I'm on a long-ish trip.

Thanks. Great info!

The size depends upon how far/fast you want to go. If you want to be able it drive normal, just get an extra wheel and normal tire. People almost GIVE the stock size Pirelli All Seasons away.

My 2018 Hellcat's driver side rear tire picked up a nail or something. Got a low tire warning light at a stop light. Called up the tire pressure display and sure enough the driver side rear tire was low.

Long story short as soon as the light changed I made for a parking lot and picked a space that would allow the flat bed tow truck operating plenty of room to pick up the car if it came to that.

Got out the tire kit. Followed instructions and in about 15 minutes the tire was holding air and inflated to around 40psi. I wanted "extra" air in case the goop didn't stop the leak.

But it apparently did for I made it -- admittedly just 4+ miles away -- to the nearest dealer with the tire holding pressure all the way. Once at the dealer I had both rear tires replaced. This because the tires had too many miles, too much tread wear difference.

While waiting for the car I went to the parts counter and bought a replacement canister of tire sealant.
