It's cheaper to buy non-RFT and a tire in a bag kit.
RFT are toast if you drive more than a couple of miles or so with them flat.
To save the tire, you need to not drive on it.
Also if you are stuck on a long trip, you will wait 3 days while they source the RFT that nobody stocks.
The safest thing is a spare.
