The folks at QuadBoss sent us a gallon of their famous ATV tire sealant to check out. It came in a cardboard box and in the form of a one gallon white bottle with an attachable pump. You basically take off the cap and then insert and screw on the pump assembly. The directions are printed out right on the bottle. To give you an idea of what this is supposed to do, here are some bullet points:

•Seals up to 1/2” puncture in the tread and 1/4” puncture in the sidewall
•Stops bead leaks and pinhole leaks in rims
•Will not solidify or freeze (above -33°F)
•Will not rust steel, corrode aluminum wheels or clog valve core
•Environmentally benign and water washable
•Works for the life of the tire

Just perfect for our older stock Dunlop tires that tend to leak small amounts of air. Keep in mind, It’s almost mid January and we’re here in the Northeast where temperatures dip down to the single digits at night. So since it’s not supposed to solidify or freeze, we gave it a go.

Installation is not hard. You will need a tire valve core remover, a tire pressure gauge, and an air source to replace the air you need to take out. We’ve got our little screw on valve core remover that the auto guys use and a shop air compressor to fill us back up quickly. We started by taking out all our valve stems, so that all the air would come out of the tires. We made sure the valves were positioned on the top side so that when the tire collapses from no air, you can still have access to the inside of the tire through the valve, with a clear entry way. After that, you just pump in the amount of sealant that you need. QuadBoss gives you a chart right on the bottle which says:

Utility ATV Tires (8″-12″ rims) 32 oz per tire
Sport ATV Tires (9″ – 10″ rims) 16 oz per tire
Dirt Bike Tires 4-8 oz per tire

Every pump stroke injects 1 ounce of sealant, so in our case it was 32 pumps per tire. After we pumped in the sealant, we screwed back in the vale cores, and inflated the tires back to manufaturer’s specs. Took the quad for a rip to evenly disburse the sealant. Did not affect the feel of the quad and one would never know the sealant was added. It’s a preventative measure for your tires, but in our case, we always saw a bit of a drop in tire pressure after a week. So we added this just before last week’s snow storm and took it out this week…tire pressure is all good. Looks like we added some life to our older stock tires and will definately be using this in our new tires down the road. We’re going to be interested to see how much air pressure fluctuation we get in our ATV tires when spring arrives. We’ll just have to wait and see, and send in an update.
