Flat tires

[HotelRed]

I have a couple of 90cc mini quads for the grandkids.
Many of the tires go flat after a few hours. It is a pain to keep having to air them up.
Anybody have this kind of problem with the 145/70-6 tubless tires?
I am considering putting tubes in them.

I had that problem with a riding lawnmower, go to walmart or any autoparts store and pick up some tire sealer, not fix-a-flat, this stuff is like a green goo, I can't remember the name of it, but it comes in a plastic bottle and you squirt it in the tire through the valve stem.

Harbor Freight and Tool sells the goo by the gallon. I'm using in in both my quads and have had not had to fill a tire for 6 months now and I run in the cactus riddled Mojave Desert.

the goo i use is called slime it will be great for a kids quad. I you really hard core use tubes with slime the you can rum lower tire pressure for better traction :wink:

I use Slime in my Wheel barrel.

other wise the 2-3 times a year when I get it out to use it the tire is flat.
keeps me from have to use the compressor as much.
