Weight Weenie Posted June 27, 2011 Posted June 27, 2011 Remove the valve core when inflating more air will go in faster that way. Covie- the racesport has a tubeless-ready bead, the Supersonic doesn't, so it's not the same. The Race-Sport should seat/inflate much easier
covie Posted June 27, 2011 Posted June 27, 2011 You can convert any wheel to tubeless!!UST - not worth the extra cash + they are heavier! Moolz your opening up a very debateable point here. Yes UST are heavier, and they are generally stronger, If one for instance did a Karoo type race with sharp edgy rocks then I would rather fit a pair of UST's than to try and fix 3cm cuts in thinner sidewalls. But agreed a lot of people do use normal sets and not UST's although you have to remember the following as well, the bead where the tyre sets into the rim is different on a UST tyre than a normal tyre and it locks tighter into the bead. Certain bike shops will make you sign an indemnity form if you choose to run normal tyres instead of UST, in a tubless setup, because under certain load and conditions normal tyres have been known to creep out of the bead and hence of the rim complelty causing some nasties. For instance one of the reasons i have a fair amount of confidence in the new continental Race Sport version, is two fold, once they made a slight strengthening of the sidewalls, (still not as tough as UST but better than normal) secondly they put a UST bead on the tyre to ensure it wont twist and creep. Conti now calls this a "Tubless Ready" tyre, other manucfactureres calls it a TNT "Tubes no Tubes" setup. So thats middle ground. Enough of a design factor to be better than normal tyres lighter than UST and in the middle as far as sidewall durability is concerned.

Enough of a design factor to be better than normal tyres lighter than UST and in the middle as far as sidewall durability is concerned. Definitely some fair points raised...and apologies if this goes off topic...When I initially set out to convert to tubeless - I was told that I will need tubeless tyres and rims (multiple bike shops and advice from this forum)I went as far as purchasing a UST Race King...what I should have done is tried the conversion before I bought...The brand new Race King is still in the garage and my entry level, non-UST rims and tyres are now tubeless...Almost 1000km later (regular trips to Teak (blue/black), Groenies, MTN Bike Park, Vori-bergs, USN's - without burping or sidewall damage...Maybe im just extremely lucky - but based on my luck, non-UST for me... Moto-Moto - what worked really well for my tubeless conversion was going to a filling station and inflating with their compressor. I followed the Stans YouTube videos step by step.Also bought a syringe to help fill up the tyre without having to open a section to fill in the liquid... Edited June 27, 2011 by Moolz
Dubber88 Posted June 27, 2011 Posted June 27, 2011 Found with the supersonic race king 2.2's 26": No flats on it's own doesn't do the job of sealing the micro tiny holes in the sidewall. Zero flats works great for that purpose ( any thin based sealant, stans prob better for this purpose ) Seating wasn't a problem , just struggled with the noflats to seal the sidewalls. All in all its a brilliant tire, but would recommend for lightish weight weenies, for possible low air pressures with no burp problems. Tire pressure is kept perfect after the sidewalls are sealed, just sometimes a bit of a hassle to get over that hill. On the Tubeless ready vs. UST / LUST debate. If i write off tires a tubeless tire wouldn't have helped. In my experience its half the price and they hold me the same period of time with the added weight benefit.
Moto-Moto Posted June 28, 2011 Author Posted June 28, 2011 Thanks for all the info. All done! Installed new rim tape and valves, lots of soap and water, sealant and one garage pump
