Expensive, but always had good success with these tubes.

Michelin Airstop Tube 8.50-10 Str

Did not use them. They were ordered on the basis of an erroneous FAQ, which is now fixed. ACS took them back for full refund and pre-paid shipping too!. The only thing better would be to have a Michelin Airstop tube in 8.50x6.

Michelin Airstop Tube 8.50-10 Str

Installed a Michelin Airstop tube on the left main during annual of Dec 2020 on my Grumman Tiger, this has held air very well, so well that I went ahead and just bought a new tube for the right main. The tubes are worth the money. Highly recommended.

I’ve had 5 flat nose tires in 5 years. Some of the times quality of the tube was the suspect. Thought I’d try this tube and see if the extra cost is worth it.

Unlike the recently purchased Dresser Leakguard tube that would not maintain air pressure, the Michelin Airstop tube has performed flawlessly. It is worth spending a little extra to own a better tube on your airplane.

Best tube you can buy, been using them for many years. These tubes hold air extremely well, requiring inflation monthly compared to daily with lesser quality tubes. Five stars.

quickly received and installed the next day. First time in so long I haven’t had to service the tire before flying. Packaged well the excellent instructions

Great service

New tube arrived on the day projected. I installed it the following day with good results. Happy customer.

Order process easy as usual. Product arrived sooner than expected.

I used pump air almost every week. Switched to Michelin Airstop tubes and now I barely need to add air maybe once a month.

Feels like a quality tube. I can’t imagine spending 30 bucks less for a lower quality tube considering what we put these things through.

Good product and reputation. Stays reliable through life of tire.

Unless you like to add air to your tires every few weeks get Michelin Air Stop tubes. The Gold Standard for aircraft tubes.

Great tubes. Installed easily.

Aircraft tubes tend to leak, so I bought the more expensive Michelin tube and have had good success.

Came already powdered up...excellent quality.

Tube delivered very quickly. Easy to install

Ive always used Michelin tubes and have never been disappointed. I dont think it pays to skimp in this area.

Good service, good product

Decent price for small quantities like we need as a non-profit school. Always a pleasure talking with your sales people, they are always helpful and professional.

Excellent tires and tubes, have been using Michelin for many years on my plane with the best service. No having to check and air up every month!

A quality tube, easy to install and does not leak.

Great quality and were pre talced. Fit and finish were spot on and I am happy. Time will tell if they do not leak down.

Easy install. This is a nose wheel with a hub cap. These tubes retain air pressure very well so it will reduce the hassle of adding air as often.

Had three flat tires on my right tire with less expensive tubes and not one flat on the left tire that had this brand and type of tube.

It was flat when I received it, but it turned out to be round and held air once installed inside the tire and mounted on the wheel. It was the most fun I’ve ever had changing an inner tube, including the time I was floating down the river and swapped tubes with one my buddies right in the middle of a set of rapids. Good times. I bought two. Can’t wait for next time.

Excellent quality, complete with everything needed .

Good quality, used prior with great results. 90 degree valves stem aligned perfectly with my 182 Cleveland nose wheel hub hole.

Nice quality tubes and had used them before. Valve stems aligned with my 182 Cleveland wheel hub holes perfectly.

I have been using these tubes for about five years since we had a rash of flats using Goodyear tubes. They work fantastic and are worth their weight in gold. Highly recommend.

The airstops do what they say. Pressure stays up for months. My old non-airstops seemed like every couple weeks they were down a couple psi.

I wish new tubes would include a bag of talcum powder for the installation and long term durability.

Unfortunately, one of these 3 tubes had a defective valve stem and only half of it could be removed. I sent it back but I did not have time for another week of downtime waiting for replacement so I was forced to re-use the existing tube. Would have expected better quality control on such a pricey tube.

My issue was tat my previous new tube was leaking about 15 lbs in a month. I pulled the tube and found absolutely no leaks both under water and with soap, either in the rubber or valve stem after 30 minutes. I am to assume that the rubber of this tire made in Mexico uses substandard materials that weep air pressure over an abbreviated amount of time I was told that this new tube is far different. I installed one about a week ago and it seems to be holding pressure. I will not know for certain for at least three more weeks. I am not happy that there is a tube for my nose wheel which suffers from the same problem. I have suggestions from fellow pilots/builders on what to try. Gus Gustavson GlaStar

Bought three new Airstop tubes in mid November. Two tubes were fine the third came with a valve that was broken in two pieces and could not be removed from the stem for installation. I sent the tube back and was told it would need to be inspected by Michelin before credit would be given for the return. I was told it could take a month 6 weeks later still waiting. I didnt buy the tube from Michelin - I bought it from AS and expected better service. Bad enough - I could not complete the job that day. Instead, I got a new job... spend weeks tracking a refund :(

Less than 2 years old and is leaking at seam. (visibly splitting) The tube it replaced cost 1/3 as much...and lasted 3 times as long.

Very disappointed. Slow leak developed in about 18 months where two seams (the spiral seam and the diameter seam) cross. No puncture -- no visible hole -- but bubbles when pressurized under water. But a fast enough leak that the tire goes flat tire overnight. Maybe they had a bad week in the factory (W 43 2017) on P/N 092-308-0. Clearly a manufacturing defect and totally unacceptable for a $100 tube.
