After several months of delay, I decided to take the plunge and invest in a pair of Tubliss tires for the Yamaha WR250. The installation was easy and the video at the company web site has an excellent video tutorial on the procedure.
Like many successful inventions, the purpose is simple. Eliminate the need to use a motorcycle tire tubes.
Instead of trying to seal the rim to keep air in the tire, the inventor at Tubliss sealed the gap between the two tire beads with a special rubber inner liner or in laymen terms a simple rubber bicycle high-pressure tube. By putting a one-off bicycle tire in the center of the rim and inflating it, the gap at the bottom of the tire is sealed, making the tire an airtight chamber and eliminating the need for the dreaded motorcycle tubes. It turns the outer tire into the motocross equivalent of a bicycle’s tubular tire into sew-up tire often seen on high-end racing bicycles.
Once installed on both the front and back, I developed a slow leak on the rear high-pressure bladder. I checked the web site and the solution was simple...empty the tire pressure in both chambers and squirt soapy water around the tire bead to increase the sealing factor by eliminating friction between the metal and the tire carcass. Presto, the soapy water suggestion worked! If you don't have soapy water, Armor All works fine.
Then it came time for a bike shop to balance the tire. The Tubliss tire system comes with a beefy metal rim lock and the result is in order to balance the tire, you will use almost double the amount of balancing weights to offset the internal rim lock mass (see gold rim lock below).
After the balancing, it is recommended to use your favorite tire sealant to help increase the puncture resistance qualities of the tire. I prefer Ride On, so I poured via the valve stem the correct amount based on the tire sizes. Then it came time for the test ride....
The Tubliss tire system has disclaimers stating that it's technology is only for off-road riding. I don't know why this matters but I think the liability attorney for Tubliss suggested inserting this to reduce legal risk. Anyway, eager to ride the bike on side streets and eventually move into the high-speed mode, I was curious to see how handling would be impacted.
After spending a few hours on the various local routes including high-speed bursts up to 85 mph, the Tubliss tire system worked well. I did not detect any vibration or wobbling due to the extra balancing weights or the added tire sealant liquid. Eventually, a few days later I was afforded the chance to take a quick 800 mile weekend trip consisting of both on and off-road tracks. The Tubliss system again worked very well. I checked the pressure on several occasion and no leaks were detected. A word of caution about tire pressure...
The bicycle high-pressure tube portion has to be kept at 100-110 psi, so if you're running a small air-pressure pump off the bike's electrical current, most portable pumps may NOT be able to fill a bicycle tube to 100 psi, which might require a CO2 cartridge system or a high-pressure bike pump. I even encountered some gasoline stations air pump not having sufficient pressure to fill the high-pressure tube. I would suggest checking the ability of your portable pump to fill the inner chamber to it's capacity of 110 psi in the comfort of your garage instead of on a road trip!
Nevertheless, the Tubliss tire system delivered on it's promise. As a matter of fact, I can't imagine ever using tubes tires again! The other benefits is you can run the tire pressure very low and not have to worry about a pinch flat often associated with tubed tires. Additionally, should you get a puncture than cannot be repaired with a plug kit, you simply remove the tire and leave the Tubliss tire in place. It is so easy. So, I would give Tubliss tire system a five of five stars. It is an product worthy of it's claim.
