If you have TPMS (tire pressure monitering system) or your car/truck tells you that your tire is low, only plug, NEVER put Fix-a-flat or Slime in it. the sensor is trashed if you do, and federal law says that the shop that discovers this has to replace the sensor. they range from $50-$150.

Cheap gummy plugs/kit from wal-mart
works as a temp plug, i.e. get you off the trail or home, until you get to a shop. they can and do last for the life of the tire, but they are prone to leaking. a shop will actually take the tire off, and plug the hole, then put patch over the plugged hole. as to the actual kit, i think the pistol grip are easy to use. (be careful, they are plastic) pliers are good for pulling out the nail, but side cutters are better. you can get a grip with less. (blade side down)then rasp out the hole, feed the gummy through the needle, insert 1/2 into tire, twist and pull the needle out. should have two ends sticking out the outside.

fix-a-flat

doesn't

basically latex and compressed air. supposed to clog and fill hole, mostly just sloshes around. dries into a sticky gummy layer. after 6 months-year in your car it will set up in the can. only advantage is that has the compressed air in a small space (can, smaller than a compressor)


Slime (the chunky green stuff)

works like a champ on low pressure tires (lawnmowers, atv, golfcats, so on)

cars, sucks!

supposed to clog and fill hole, works with under 20psi tires. cars are too heavy, and go too fast (heats up, expands,)


a compressor is a really good idea for your car kit. besides filling up a flat, you will not have to fork over your quarters to fill your tires when you check them every month (hint)

to find flats, the best way is to take off the tire and dunk in water. considering that has not been a posibility when i had flats, diluted soapy water does wonders. (soap makes bubbles to see leak) I have Dawn in my truck for that and to wash! it works.

as to sidewall repairs, at a shop it means a new tire. but the gummies work pretty good for at least slowing the leak. once you put the thing in leave it alone. dont mess with it, pull, twist or what have you. if the tire is in decent shape, you will get to where you need to. put your spare on asap.

if you are off-road, there is a big possibility that the bead will come off the rim. this can be reset in the bush. it is either dangerous or really REEAALLLLYYY messy. ether, squirted into the tire and lit (yes fire) will set the bead or blow the tire up, depending on the amount. or ratchet a strap around the middle of the tire, pushing the bead towards the rim, then you can fill the gap with a tremendous amount of grease (thicker the better) and air it up. when the bead sets there will be a explosion of grease. i guess better greasy than bear-food.

if you want to see the ether trick, it happens at most local tracks at least once a weekend, unless its been banned.

btw I work at a shop, on tires!
