Tire question

[Cavman]

Thanks to all for the quick, thoughtful and helpful responses.

Opted to order a Continental ContiComfort Kit from Tire Rack plus an extra cartridge.

According to them, I can use the pump and the sealant on a runflat (as well as a non-runflat tire) and the sealant can give me another 50-150 miles. Although I just went deeper into the product's specifics and it doesn't look like it is recommended for 315s. Oh well. If anyone has any experience with the product feel free to chime in.

Won't have room in the car for carrying an extra winter wheel/tire, although I had thought of that, but nixed the idea because I would actually need to bring a front and a rear tire to be totally covered. Then thought of putting them on the roof a la a Range Rover in Kenya, but my wife thought I was insane! Ha.

So will go with the Continental Comfort Kit and a few fingers crossed.

Thanks again for the replies.
