Never had a flat in my 6 years of driving but I know as soon as I ditch the spare I'll get one.

Do things like prestone tire jack work? I wanna ditch the spare but I want to have something just in case.

Sorry If I posted this in the wrong forum

The tire stuff works if the hole is small enough for it to seal.

Fiber based sealers work best for larger diameter holes, but also can clog the valve easier if the valve can be left in when they are put in.

If you are considering ditching the spare, maybe the tires that you can run flat are in order. That way you are never left stranded over a tire.

Dont use tirefix or fix a flat or any of that nonesense. Its mucho bad for your tires and youll get the third degree from the place that plus your tire case it crystalizes or if its the foamy stuff itll turn into aplyable peice of cemet on the tire hole. Runflats or carry the spare.

I got to see that crap in a tire, Please don't put that in there. It makes it 3x as hard to get that tire off the rim.

It can also unbalance a tire temporarily, and it puts weight far from the center on rotating, unsprung mass.

When I first got my mtn bike i ran it, but since then i'm on regular tubes.
