When you need to use QiangBao® Tire Sealant?

Our tire sealant best be used for

  • Areas has bad road condition where punctures happens very often.
  • Areas max speed under 120km/h (if with two front tire filled), 80km/h (If with four tires filled).
  • Vehicles drive off-road most of the time, like trucks, agricultural & construction vehicles equipped with tubeless tire.
  • People always drive safe and concern safe drive more than comfortability (imbalance occur at high speed).
  1. It’s just ok to have two front tires filled, because puncture happens to front tires in the most cases.

Why tubeless best repair with tire sealant?

Cold patch require everything be done perfectly, or the patch would leak, and after a period of water and speeding rotation of tire, the patch could peal off.

Hot patch actually is the best way to repair a tire puncture, but it demands high performance of machine and technical, the tire would be deadly burned and deformed when temperature is not controlled precisely.

Mushroom plug & self-vulcanizing string strips enlarge puncture when applying. After lubricating oil dries, plug & string became aged, harden, or get loose when hit by objects, leading to air leak again. When you have three plug in one puncture, the tire is dead.

While with tire sealant, it does not enlarge the puncture size, last longer than cold patch, do not need to heat the tire under risk and burn out or deformation. You just need to install tire sealant, as long as you have it in your tire, it will seal almost every puncture you got on the tread area permanently for repeated times. You do not have to walk your motor to repair shop and spend extra time to have a traditional repair that might leak very soon. So why not use tire sealant? It worth it only to have 3 punctures sealed with one-time installation.

What is Cold Patch & Hot Patch?

The cold patch required buffing the inside of the tire and applying a cement. Then the correct sized patch was placed over the injury and a special tool was used to” stitch” the pacth to the tire. I don’t mean stitching in the sense it was sewn on, but that this special tool was rolled over the patch until it was sealed against the tire.

Cos: The drawback to this method was if you didn’t do everything perfectly, the patch would leak, and after a period of time of water-wade and speeding rotation of tire, the patch could peal off.

Hot patching involved essentially the same procedure except the patch was heated and melted to the inside of the tire. There was a special heating clamp that went on the tire to do this. If usually took about 15 minutes to heat the patch to the tire. The advantage of this method was that the tire and patch become one piece.

Cos: Actually this is the best way to repair a tire puncture, but it demands high performance of machine and technics, the tire could be deadly burned and deformed when temperature is not cintrolled precisely.
