A gentleman at the Gilmer County airport was kind enough to loan me one of his new tubes when I had a flat tire and the tube needed to be replaced. I ordered this tube as a replacement that same afternoon. Aircraft was able to deliver the tube the next day. Thanks Aircraft Spruce and UPS for the quick delivery!

Valve stem was not treaded or milled correctly. Unable to detect until the tube was unpacked. The need to use the tube over leaving the aircraft AOG it held air . You can’t just replace a tire on a aircraft without a new tube in my opinion the work required to just replace one without the other is not a good safe practice.

Excellent service they do a great job and they also send me without any charge a new tube

Arrived on time as described

Installed easily and was nicely coated with talcum.

Seriously overpriced, but can’t roll with a flat tire. Had to pay it. Product is OK. What can you say about an inner tube?

Aero Classic makes a standard tube and a leakguard tube. I have seen quite a few problems with their standard tubes but I have never seen one with the leakguard tube. I just looked at my quick books program and in the last 10 years I have installed 24 of the 6.00-6 leakguard inner tubes and 8 of the 5.00-5 tubes. I have never had an inner tube failure on a clients airplane. My advice is to make sure you are buying a Leakguard inner tube and avoid their standard tubes.

Saw the low rating, thought Id add my 2 cents. We have run these (6.00-6) for many years in 3 Cessna 185 amphibs and have had fantastic service from them. We take them out of service when the tire is worn out, probably 600 hours or so, and have only seen one failure at a valve stem. I certainly understand the frustration of others poor experience but ours has been great. I recommend these to all the folks we deal with.

These tubes rock. I put them on my Comp Air 6 and I havent had to add any air in a year. Most other tubes you have to top off about every three months. As it says in the instructions, recheck pressure the next day after initial installation because the air trapped between the tire and tube will bleed off. After that they just dont leak. Well worth the slight extra cost over standard tubes.

Not much I can really say, its an inner tube. It fit without issue, was well packaged and I hope it will give me at least 7 years of service like the last one. The construction seems to be much thicker than my old one so that should help.

The threads on the tube valve stem were poor quality, notified Aircraft spruce about this issue.

I replaced my old tubes when I replaced my tire back at annual (about 100 hours ago). Ive found these tube to need and AIR refill about the same as my old tubes - once a month I have to add about 5-10lbs. (Cessna 182RG, calls for 68PSI) I keep my plane in a hanger in central Florida. I was hoping to be able to go longer without refill based on some of the other reviews I read. But the quality of the tubes themselves was excellent.

William B Verified Purchase

LEAKGUARD INNER TUBE 15/600-6

David K Verified Purchase

LEAKGUARD INNER TUBE 280/250-4

4 stars because I have bought and replaced several of these inner tubes...I recently got one that leaked out over the course of a few days after instillation but before any flight was done...disappointing but not completely unheard of.

Purchased these retread tires for a 182 RG. The Cessna manual specifically warns against using retreads due to potential fouling in the gear wells. The owner and a well know managed maintenance company still wanted to try them. Both tires rubbed on the gear well lips and about 1/4 inch had to be trimmed to make adequate clearance. On fixed gear planes the value of retreads is good and they provide long service life, however be sure to check for adequate clearance when using them on retractable gear airplanes.

I run an MRO and have used these tubes for years without problems until this month. I too experienced the pinhole in the side wall. I think that low air pressure could contribute to this problem along with not using enough talc when installing. We have literally installed 100s of these over the years and have only seen a few failures.

Don’t know. Haven’t been able to use them because they haven’t shipped the tires they go in. Nor have they told me when they expect to

Craig S Verified Purchase

LEAKGUARD INNER TUBE 600-6 70* BENT STEM

The TR-67 valve stem on this tube does not have a straight 90 degree bend like the old one with the same part number had. It has a radius bend before the straight part that come through the grommet in the wheel. This extra bend causes the stem to put stress on the grommet which, I suspect, will cause it to wear prematurely. I attempted to contact product support regarding this and left several messages, but no one ever returned my calls.

Good tube but way overpriced!!

LEAKGUARD INNER TUBE 500X5 TR-67

We have the worst luck with all leak guard 500-5 tubes. They get pin holes on the side of the tube . Always replacing tubes, never bought so many tubes. VERY UNRELIABLE!!! This is a topic at the IA meetings.

I have had to replace three of these tubes due to small pin holes in the sidewall. Not so leakguard

Immediately after installation an attempt to add air was unsuccessful. Neither an air fitting from compressor or from portable tank would add air, but instead only succeeded in letting all air out for a totally flat tire. Repeated efforts to add air failed so ended up removing fairing and tire for better access to valve. Took tire to another mechanic who had a fitting that would add air, but another would not. It seems the valve stem is too far recessed for most filler fittings to properly engage it. Very inconvenient at the least... hope never need to add air again, especially in a transient situation any attempt could turn into a flat tire.

Steve H Verified Purchase

LEAKGUARD INNER TUBE 500X5 TR-67

Had replaced nose tire and tube on our 182 and used a leakguard tube. Got a flat away from our home airport, pinhole in sidewall. Replaced it Oct of 18 with a new leakguard tube. 2-7-20 got another flat away from home airport and you guessed it, a pinhole leak with more looking like they were not far behind. Tire is good and tire talc was used both times. Looking at buying another brand tube and trying it out.

I have installed 2 of these tubes on the nose wheel of my Piper Warrior and both have developed pin holes on the side wall with no apparent puncture through the tire. The first only made it 30 days. The second made for 3 months. But had 2 large holes and was cracking along the same lines all on the middle of the side wall. Would not recommend.

I have installed a 3 of these tubes on my RV6 over the past 3 years. Every one of them has failed with a pinhole leak in the sidewall with no damage or penetration to the tires. I wont buy any more.

Last annual I replaced my original Leakguard tubes with new. 9 months later 1 tube developed a pin hole leak in the side causing deflation and damage to the wheel pant. Upon disassembly and inspection 3 more spots on the same side of the tube show potential pin holes developing, indicating possible manufacturing defect. The original tubes were made in Canada, the tube that failed was made in Mexico.

Had this 500x5 tube in my nose wheel for 17 months. Tube went flat for no reason. Found pin hole on side at mold seam. Shop told me they have had a large number of these tubes failing. Definitely seems like there may be a manufacturing defect in this product.

These WILL develop a pin holes after a very short time and leave you with a flat unexpectedly. I thought maybe it was a bad batch or something so I tried another order and same thing happened.

Both tires had defective valve stems.

I have used these for years, on my personal aircraft, my company aircraft and my clients aircraft. In the last three years I have had 6 failures in 6.00x6 LeakGuards due to either pin holes in the sidewalls or failed seams. The manufacturing process has changed and the quality control is not there, I will not buy another one or recommend them to customers. Aircraft Spruce Customer Service has not been particularly helpful in replacing the defective tubes or resolving the issues with them.

I only had my old one for less than fifteen hours when it developed a pin hole leak. The material appears to have broken down.

Never again. This is the second Aero Classics tube that has failed on my antique airplane that is flown often with meticulous attention paid to tire pressure, tire condition, wheel condition, etc. This failure was a pin hole opposite the valve stem. I own three vintage taildraggers that fly all the time - my daily driver flies 100+ hours per year. I cant risk a high value vintage airplane over a poorly made inner tube. Just ordered six Michelin Airstops from Aero Performance - all the Aero Classics junk is going in the trash where it belongs.

Did not last 4 months before it had pin hole leaks, pay me now or pay me later - get michelin.

Another pinhole failure report for Aero Classic Leak-Guard 6.00-6. It lasted 3.4 years (and 137h TT). No crease in the pinhole location. I contacted Desser via online chat but they would not acknowledge there is a quality issue. All they offered me was a $20 discount on a new one. Pathetic. Interestingly, my nose wheel had a Leak-Guard and failed the same way 4.7 years ago. I replaced it with a different brand. So Im changing both my mains for a different brand. PS. I never write reviews but decided this is a safety issue.

I replaced both tires and tubes on my Stinson three years ago and both have failed due to the same pin hole flaws in the sidewalls. I use 700x6 tubes and got two replacements from a friend and both failed with the same flaws in the sidewall. They were all stamped with the date: Feb 2013. I suggest you avoid this brand tubes.

A&P mechanic here. Over the last 2 years Ive had 4 of these tubes fail on my customers airplanes. All had small pinholes/cracks in the sidewall. Its as if these things become brittle. Ill never buy again and I have warned my customers to steer clear.

Just had 500-5 AeroClassic Tube go flat on the nosewheel of my Cardinal RG. Installed 2-2013 and 500 hrs ago & probably that many landings. Inspection revealed pin hole leak on side wall with several more developing along the sidewall. Held air well over the years but disappointing to see it fail like this.
