Vittoria Corsa Pro with Tire Liner Insert installation - clincher to tubeless conversion 1 of 3 

Thanks for this, George. Air Liner road saved my skin last week in a downhill fast sharp, leaning-over right turn (@about 20 MPH) with a front wheel sidewall puncture/blowout right at the apex. I was able to control the turn and the stop, the wheel was protected, I didn't crash and I rode 10 miles home flat (sidewall wouldn't hold bacon strip). One thing the insert did was slow the air outflow from the puncture by, I think, partially obstructing it physically. Also, it prevented tire roll-off which was a very big deal! I use hooked bead carbon wheels. I wouldn't trust hookless in a situation like this. Another thing: you had trouble with sealant leaking around the bead after initial installation. I think that your not hearing the pop-pop-pop on first inflation was indication of not setting the bead fully. Sometimes it takes a bit more air pressure to get this to happen. I may be wrong about this, but I've never had a successful tubeless tire mounting without that sound.

We gave up trying to install the Air liners with 28mm GP5000. It took two of us to install the Air liners with 30mm GP5000. I have also used Orangeseal sealant too.

The sealant nozzle is threaded on the inside which always you to screw the bottle onto the valve for a sealed connection and no mess. Threaded on the outside as well if you use a syringe set up install sealant.

Gonna be interesting to see how the sealant is going to hold up when you plug the hole. Continental GP5000 didn’t pan out for you. If the plug doesn’t work like the GP5000, it’s gonna need messy to put the tube in . And you have to carry the messy liner home. Look forward to see your review down the road.

At 11:20 to :50 you’ll find it easier to finish the tire install at the valve. This gives the tire the absolute most clearance since otherwise it is restricting the tire from the rim valley. Tire in the rim valley all the way around to the valve area.

Thank you for testing these out George!! I've been eyeing them for over a year since I first saw them. I do have to say, I feel like we're really starting to go in a circle: - we wanted to remove the tube to decrease weight and tire pressure - to make sure the tire doesn't blow off and leak too much, we made the tolerances on the hooks/beads much tighter - the tire becomes slightly more expensive than clinchers due to higher manufacturing cost for the tolerances - we added back sealant to prevent flats (and adding sealant can be an adventure in itself) - we're adding a liner in case our sealant fails - we still carry a tube in case of flats All this because tubes were that much of an issue to begin with? I'm on my 2nd set of tubeless and I may be going back to latex clinchers on my next round of tires out of pure simplicity.

Good video, thanks!!

Great video! I can't believe you made that look so easy. Don't forget your dynaplug. I think you're gonna be surprised how well they work. I got them on my commuter and on my tri bike.

I'm anti-liner except for the most chunky, technical MTB riding. They add a level of complexity which is completely unnecessary and are way too expensive, I still don't understand how the sealant flows freely to a puncture with that liner inside the tire. And what are you going to do if you're on a ride with a puncture that won't seal where you have to install a tube?

I'd been running the new Corsa Pro G2.0 without liners for a few months but had way too many punctures. A couple self sealed, a couple i was able to plug but a couple were big gashes or sidewall that I could not plug. In those cases was quick to put in a tube but on the heavily potholed roads I ride in NJ and sometimes into NYC these tires while having great ride quality were just too fragile. I've since switched to GP5000 AS and have ridden a few centuries with them and so far so good. I'd been runniing the clincher GP5000 previous with good luck. Anyways just adding my experience and hope you have good luck with the corsa pros.

I recently got these same tires, I was surprised how easy they went on, way easier than GP5k. They ride very smooth (32s) and got my first puncture on the 2nd ride. I agree with everything youve said about them. Now I need to get a replacement carbon wheel after I smashed it on the 3rd ride hahaha

So I have thoughts on Air Liner Road and how they get along with certain tires. I was initially convinced Air Liners were great... With Continental GP5K S TRs, they went on without much hassle once I got the technique down. Getting them off was easy too...with a little bit of elbow grease, the bead pops off the bead shelf on each of my wheelsets. The first inconvenience is that it makes pouring sealant directly into the tire almost impossible. The foam takes up too much volume so the sealant pools above the foam and tends to spill out of the tire. Injecting the sealant through the valve works okay with certain valves and certain sealants...I found Orange Seal + Fillmore valves to just barely work. When I mounted Corsa Pros with Air Liners...again no issue with mounting. Recently however, I tried to remove the tire and it simply would not pop out from the bead seat. When the tire is worn out, I'm fairly certain I will have to cut it off. I also did not have much luck with the Vittoria Universal sealant. It's sticky and messy compared to Orange Seal and I found it ineffective at sealing two punctures. I had to use 3 DynaPlugs which would occasionally reopen and bubble up. I found that small cuts in the tread would end up weeping a little bit of water or glycol from the sealant, which was strange. Swapping out the Vittoria stuff for Orange Seal fixed both those issues and also improved overnight pressure loss. Overall I felt that the liners made the tires feel a little more firm at the same pressures from a reduction in air volume. If I keep using the liners, I will not be using them with Corsa Pros anymore. The Corsa Pro tires by themselves are okay I guess. They inflate to a nice aero shape and have tons of grip, almost too much grip as the tread + tread pattern picks up sand/pebbles and flings them at my DT / ST. Puncture resistance seems lower than GP5K S TR, but there is no question they have better grip when railing corners on technical descents.

Hi,,im confused..title says clincher to tubeless..so the rim is hooked{clincher} ? and you put on a tubeless tire with no bead? or the sealant converts a normal setup to tubeless? thanks George!!

Have these installed on my wife’s bike 32 tires. No issue installing, but when I tried to take tire off due to a slow leak and there is no way I can get the beads up and over the rim. The insert keeps pushing the bead back in the hooks. Tried the clips but still not helping. Interested in your experience with removal.
