RyanV Posted July 18, 2011 Share Couldn't wait to get my hands on the Conti X-King Racesport 2.2's. These tyres are claimed to be tubeless ready and at 480g, I just had to get me some. 4 tyres, two different wheelsets and two weeks later I still couldn't get the tyres to hold air (3 and then 4 cups of Stans per tyre). Put the tyres in a bath and guess what...these things leak air like a sieve through their sidewalls and carcass. So a big thumbs down to Conti and their tubeless ready claim. Real pity as these could be a great tyre if they sort things out! Big up to Evans Cycles for replacing the tyres with the UST versions...back to the tried and tested stead! Took a while to get a response from them, but no quarrels regarding replacements. Link to comment Share on other sites More sharing options...
Big J-WP Posted July 19, 2011 Share Did you scrub the inside of the tyres with Meths likes they show on there website. Worked perfect for us. Link to comment Share on other sites More sharing options...
lock Posted July 19, 2011 Share I also have two sets but haven't tried them as I'm concerned about their durability. Any issues yet WP? Link to comment Share on other sites More sharing options...
gummibear Posted July 19, 2011 Share I am using the Protection 2.2 and i have had no problems with sealing.I cleaned my rim and tyre,lubed with some dish washing liquid,added sealant and inflated. Been running them for about 3 months now and i cant see anymore wear compared to my Mountain Kings that are same age. I do have to pump them one a week as they do lose a little air but not much.
