    Flat Tire Woes - Riding Mower

    My riding mower has tubless tires (I think most do). The front right broke the seal when the air was low and the driver was too close to the retaining wall.

    I got the tire to refill but it seems to go flat every few weeks.

    Should I seal the tire with a liquid sealer or get a new tire or put a tube in the tire?

    Thanks
    Thanks again,
    Mike

    Fix a flat or get a bottle of slime.

    I had a tire on a hand cart do that to me for a while. It had tubeless tires and the seal was broke from trying to move something with low pressure. I kept trying different things to get the tire to re-seat the seal (wrong terminology I'm sure). What finally worked was jacking the pressure on the working end of the air compressor to 100 psi and allowing the tire to fill up really fast. I heard a familiar pop and I knew the seal was seated again. Haven't had a problem in months, still holding air.

    Try spraying some silicone around the bead of the tire and over inflating it

    Bead sealer. Black tarry looking stuff. Rim has to be clean of rust and dirt as well. On most tires, there is a warning on the tire as to max pressure to seat the bead. Not a great idea to exceed that. Don't even try to plug little tires like that, they'll nearly always leak. Take them off the rim and put a boot inside. Slime or fix-a-flat will work, but you don't want to be the one that has to work with it when the tire needs changed. Nor does the guy at the tire shop. They will curse you. Been there done that, as a customer and as the guy doing the tire repair. YECHHH! Front (non-drive) tires are usually ok with tubes, but drive tires that small have so little pressure that they'll often shift on the rim and cut the valve off the tube. ATV/ATC's are the same.

    I put a plug in my front tire 3+ years ago and it seemed to work OK. I did put a small amout of slime in as well.

    I tried the slime 2 or 3 times. I had one tire that just kept going down. Then the other rear tire stopped holding air as well and the front two seemed to leak slowly over time as well.

    The whole thing was just too annoying for me. I had tubes put in all four tires and was done with it. Just want to be able to go out and crank up the mower and mow. My wife only works part time so half the time it's her doing the mowing and I didn't want her to have to worry about whether the tires were inflated or not.

    I have a friend who's uncle works for a car dealship as a mechanic. As of late lots of people have been wanting those really large, thin tires. They apparently are hard to get seated even with the proper rim and wheel sizes. His method for seating the tire on the rim is much more exciting/dangerous.

    He sprays WD-40 into the tire and drops a match in.
