If you're on the road and really need to go and get going, fix-a-flat, while not perfect, will get you where you need to go, no matter if it's 10, 100, or 500 miles. Meanwhile, here I am, I've driven for over 3 hours with a slowly leaking tire where I started the trip at 32 psi and ended at 20 because it had to be done (normal tires).Īnswer: Since you're in a situation without a spare (as is my mother, and this is what I tell her), yes, I believe that fix-a-flat is good enough for you (depending on your situation, this is somewhat personal preference) in lieu of getting runflats. To top if off, (at least the older models of runflats) would blow out at low pressures, so if you had a slow leak, you're completely toast. Also, when they do go flat, you generally need to replace them in pairs, in my experience. Given those three things, here's some issues I have with runflats: Runflats are only good for, what, 100 miles? And they also need to be replaced more frequently (treadlife is worse), on top of being the more expensive tire like you said. This actually isn't a huge deal, it just means a little more work at the tire shop, and you need to remember to bring it up (why I'm mentioning it).įinally, with fix-a-flat, you'll have to spend some time on the side of the road / at a gas station putting a band-aid in/on your tire. See this answer to a previous question - but essentially, after getting to a shop after using fix-a-flat, some work might need to be done in order to get the tire properly balanced, since the fix-a-flat "goo" can throw the tire out of balance until it is removed. Fix-a-flat isn't great for your tires, either.

With fix-a-flat, if you have a sudden loss of pressure, you'll have to limp your car to a gas station or carry a compressor around. Runflats are good because in case of a sudden loss of pressure, they'll get you to a tire shop. In the case of a large puncture / fast leak, you'll need to add air.Here's some issues I have with fix-a-flat:
