I'd suspect more hard-tails have tubed tyres than don't, given they are usually of the custom type and have spoked wheels. Hell, it's not totally unheard of for people to run car tyres with a tube in on a hardtail. Big 4" avon safety mileage are probably the most common tyre fitted to a hardtail and they are tubeless fitment.
Fitting a tube in a tubeless tyre is fine. My MZ street moto had this as standard and it was TUV and type approved (for those specific, named, tubeless tyres, some of which were proper sportsbike tyres). I used to run them on my 350 powervalve too because the rims were in a shit state and wouldn't hold air properly.
The main issue with tubed tyres is if they are running at excessively low pressure and the tyre slips round on the rim, this can rip the valve off and cause an explosive deflation. Yes, trials guys use rim locks to prevent this but I'd worry about how this would affect balance at three figure speeds. That said, they run with barely any air in at all.
Another option would be to fit tubeless and slime them.
What sort of pressures are you running at anyway? Maybe you could up the profile and run a higher pressure so you get more sidewall flex to soak up the bumps?
I'll add that fitting rim locks takes the "easier to fit" thing and throws it out of the window. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

This sort of thing:

However you're talking about road bike tyres >5" and similarly wide rims.
AFAIK the main issue with tubed tyres is throwing lots of torque at them - what you'd expect a lot of for offroad stuff - and the wheel rim literally spinning within the tyre. If this is a hard tail road bike I don't suppose you're expecting to do burnouts with it ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |
