Are Continental Supersonics ok tubeless.I have a set of hope hoops with stans 355 rims but want to run these as they are super light and fast but will they be ok.I weigh 12 stone and pretty much only ride light xc and commuting to work.
I've got a Mountain King, Speed King and Race King - all in the Supersonic versions and all converted to ghetto tubeless with Noflats. All fit easy and seat fine - even with a track pump. Apart from the Mountain King they hold air surprisingly well - but do need a few psi added once a week.
My mountain King though has sidewalls like a tea bag! It goes from 30 psi to flat in 2 days. So I've pretty much given up on tubeless for it.
Otherwise I've had no problems with them - I'm 12 stone. No burps, splits or punctures. I've done around 800 miles off road with a Speed on the front and Race on the rear. Oh - the black chilli is fab!
Id hesitate to use them (except possibly the Race) on the road for commuting : the tread will slow you down and they do growl and they do wear and arent cheap.
They're very inconsistent, sometimes you'll get very lucky and they'll go straight up, othertimes they'll weap sealant for days, or just be too baggy to fit the rim.
I've set up about 10 pairs over the years and all have worked eventually bar 1 Speed King which was just too loose to ever seal.
Nowhere near as easy as Schwalbe though, and the older Explorer and Twisters were easier to do than the newer Speed King/MK/RK carcass.
If you've got the tyres you've nowt to lose, but I'd replace with some Rocket Rons or something in the long run, lighter than a Speed King with far more grip, or a Racing Ralph which is more like an MK but tougher.
Sorry just to confirm they will be speedking supersonics.
They are usually a pian in the arse to get sealed. Took me about an hour to do it with a compressor.
But just keep trying, I eventually left compressor on, found where the air was coming and ad pulled the tyre onto the rim, it eventually takes hold and hey presto.
As long as you go out for a couple of decent rides with them, they stay sealed. go dowan a few psi weekly but not alot.
I found tho, they need a bit more than the advised fluid as i think alot of is used sealing the very thin sidewalls. Ive been runnong mine all season and had no problems (touch wood)!
