Good video on tubeless tires

I am seriously considering going tubeless this season.

Unlike tube tires I would hesitate to exceed recommended pressure. What tires are you thinking about and what is the max recommended pressure?

Keep us updated.

Saw the video and am very intrigued.
Do you need a special rim or will any rim work?

Did you watch the video, especially the place where the tube tire blew out from heat and the tubeless stayed on, the blowout was caused by heat/pressure. I will go with the Schwalbe Ones. I am going to call HED, Schwalbe and maybe Stan's, today. I believe the max pressure is 130. I currently run 117/120 and will probably run 110/115.

Stans no tubes makes a conversion that seals a standard rim. There are special rims that are sealed and have a different rim bead shape to help keep the tire sealed. I have HED3 wheels that have an Aluminum rim bonded to a carbon fibre wheel that does not have conventional spokes. All I have to add is a new valve stem.

The tubeless tire weighs more than a folding tire (tubeless, 305 g / folding tire, 205 g). But there is no tube. If the weight of a standard tube is deducted, the weight of the tubeless is, in principle, identical.
+ liquid sealant? Sometimes mfrs "forget" to include that.

Also, liquid sealant might be a bother for those people travelling, where deflating tires to fit the wheels in S&S cases, could prove to be very messy. Do standard tube patches work on the inside tubeless casing?

I received two Schwalbe One tubeless tires today, they are the 700 X 23 which is what I use on the front wheel of both bikes.

I installed one of the tires on a new HED 3 front wheel. In order to prepare the wheel for the tubeless tire I applied a liberal coat of high quality nail polish to the exposed aluminum surface and then applied a layer of electricians tape in order to protect the rim from the corrosive effects of the tire sealant.

The tire was very tight and I had to use a plastic tire lever to get it on the last few inches. I followed the instruction for installation that I found on the Schwalbe website but applied a light coating of Stan's sealant to the edges of the rim as advised by the LBS. There was air leakage around the valve stem initially but a little bit of tightening took care of that. The tire took air perfectly after I fixed the stem leakage and it is currently holding air. The tire looks good.

The total weight of the wheel is 176 grams heavier than an identical HED3 wheel that has a Schwalbe Ultremo ZX installed on it, same size 700 X 23. Some of the weight difference is in the tire, the tubeless weighed 316 grams on my scale, the valve stem at 9 grams and 60 grams of tire sealant. Significant weight gain, time will tell if this is the what I will stay with. The testimonies that I have read and the marketing hype says that it will be an improvement. We are heading for Tulsa on Monday and hope to get several miles on the bikes and the new wheel/tire while we are there.

It took right at 30 minutes to get the tire on, sealant installed, inflated and sealed. Getting the valve stem seated took a bit of time. The rim is 19 mm which made the stem a tight fit, on a wider rim it should be easier to install.
