Don’t Get Caught Without These: My Review of the Grand Pitstop Mushroom Plugs

If you’re a rider like me, there is nothing that kills the vibe of a perfect Sunday cruise faster than the dreaded "hiss" of a punctured tire. I’ve been using the Grand Pitstop Tubeless Tire Repair Kit for a while now, but today I want to talk specifically about the unsung heroes of my toolkit: the Grand Pitstop Replacement Mushroom Plugs.

Most of us have used those sticky "bacon strips" in the past. While they work in a pinch, they can be a pain to insert and don't always provide a permanent seal. That’s where these mushroom plugs change the game.

Why Mushroom Plugs?

Unlike standard strips, the mushroom shape of these plugs acts as a physical rivet. When you use the Grand Pitstop gun tool to insert these, the "head" of the mushroom expands on the inside of the tire. This creates a seal that is held in place by the internal air pressure of the tire itself. It’s a much more secure and mechanical fix than just relying on glue and friction.

My Personal Experience

I recently had to use one of these on my rear motorcycle tire after picking up a nasty screw. Here is what I loved about these replacements:

  • Perfect Fit: These are the genuine replacements designed for the Grand Pitstop tool. They fit into the nozzle perfectly every time without jamming.
  • Pre-Lubricated: They come with a bit of silicon coating which makes the insertion process through the gun incredibly smooth.
  • Reliability: I’ve ridden over 500 miles on a plugged tire (just to test it out before swapping the tire), and the pressure didn't drop a single PSI.
  • Compact: I keep a handful of these in a small zip-lock bag in my under-seat storage. They take up virtually no space.

Pro-Tip for the Road

When you’re buying these replacements, make sure you keep them in a cool, dry place. You don't want the rubber to degrade over years of sitting in a hot saddlebag. I always refresh my supply every season just to be safe, especially given how affordable they are.

The Verdict

If you already own the Grand Pitstop puncture kit, buying these replacement plugs is a no-brainer. It is much cheaper than buying a whole new kit, and it ensures you are always prepared for the worst-case scenario on the road. Whether you're driving a car or riding a moto, these are the gold standard for roadside tubeless repair.
