My '06 Suzuki S40's back tire is flat.?

Same thing happened to me. They put a "mushroom plug" in my tire. They had to remove the tire and put it on from the inside. I wouldn't trust a standard plug for very long. 5000 miles later and my tire is still in good condition. I'm thinking that cost me around 50-60 bucks, don't remember the exact amount. I know it was cheaper than buying a new tire though.

However, if yours is a tubed tire why not just have them install a new tube? Got to be cheaper than buying a new tire. If you are paranoid about riding on a repaired tire then buy a new one. Peace of mind has got to be worth something extra.

As a few others have said, since your bike has tubes, it doesn't really mean anything that the tire has a hole in it. Now, if it's a big gash, that's a different story. I've patched tubes with good success, but new tubes aren't that expensive so I'd go with a new one.

As also said, never let anyone plug your tubeless tire with one of the gooey strings shoved in from the outside. They'll just make a small hole bigger. I've patched tubeless tires on the inside and they have been fine for the remainder of their tread life.

Your S40 has spoke wheels and tube type tires. You can patch the tube but for peace of mind I'd just buy a new tube and put it in instead. The rule of thumb is if your bike came with bias ply tires from the factory then it was designed to perform best on bias play tires. While you can put radials on it you gain nothing in safety since you're still dealing with a tube type tire. It's the spoke wheels got you locked into an inner tube.

I don't think tubed tyres are any more prone to punctures than non-tubed, because your wheels are spoked and they cannot (or at least can't easily) be made airtight under pressure, I don't think you have an alternative short of replacing the wheels with cast rims. Regularly check the pressure, a tyre with low pressure is more liable to puncture and although they could turn nasty I have never had a "deadly" blowout.

If the tire is tubeless, I never get them plugged, as the plugs never hold. I have them patched. Anyway a good tire repair place would never plug a tire! The cost is usually around $12 to $15 to repair a tire.

It doens't matter where you have a flat tire, if you wait long enough with that helpless look, the first guy will pull over and change it for you. They appear, even in the middle of nowhere when you put the charm on

that sucks yo take it back to get it fixed
