I’m guessing I got lucky but want to share this. Was ATVing with wife and friends in the Black River Falls trails in Wisconsin. Great trails by the way. More than enough mud-holes to go around after about 5" of rain or so. Trails were closed then reopened. After riding through more than my fair share of waterholes I started avoiding a few. I hit a stump hidden from view with my right front tire. Darn near popped off the machine and thought I cracked my back. Went on about 15 miles and entered a road route. Machine seemed to pull to the right. Kinda forgot about the stump. Thought it was just the road. Another 20 miles back on the trails and we were back on the blacktop of our hotel. It was then I noticed the tire was loose from the rim. No air in it. Thinking back, it probably pooped loose at the stump. I could see absolutely no sign of damage to the rim or the tire. It had no air in it, yet it rode fine. I had hit speeds up to about 40mph and never noticed a problem. Went to a gas station for air (one block away) it took air right away but did not seal at 4.5 lbs. I could see a gap lager than the others from tire to rim. 20 minutes later it was airless again. Friends with, advised to add air up to 35lbs. to get a seal. It seemed to make a good seal again. Let air out to recommended pressure again. Road another 30 miles with it and it held fine.

I figured there must be sand, mud and water inside the tire so the next morning I took it to a nearby ATV shop who removed the tire for inspection of it as well as the rim. The darn thing was dry and clean inside. No rim damage at all. No tire damage found. Just didn’t make sense.

I figure I road at least 35 miles with no air in the tire and never noticed a change in the ride except for the slight pull to the right on the 1-2 mile strip of pavement. Anyone else ever have this happen. Are the tires designed to do this. Or did I have an unknown heavenly passenger riding with me. Maybe a bit of both?

Thanks to all those who responded when I knew not, what tire to buy. I love these tires. Wisconsin winter, ice, snow and summer!
