I've recently bought an aircraft with the above tyres fitted to Matco split-rim wheels.
The tyres are marked TT, (tube type) but do not have inner tubes.

Anyone out there have knowledge as to whether this is standard practice? Only came to light when I landed with a bit of crosswind drift on tarmac and lost pressure in one tyre overnight. To my knowledge the aircraft had never been landed on tarmac before.

I've been told that the tyre pressure should be about 12psi. Don't know if that's right or wrong. Aircraft is a Just Aircraft Escapade.

We have these on a Zenair CH701 no tubes mostly landed on tarmac other than more ware than grass no problem not sure what pressure we use but it is lowish will ask my colleague .

Thanks for that. I was concerned about the TT tyre on a tubeless wheel. Have ordered two new ones. Coming from BIGTYRES.. Same tyres from a well known Aviation supplier are almost twice the price.

Edit. Despatch Note from Redstone Tyres of Arundel lists the tyres at £38.40 plus VAT.
One third of the "Aviation" price.

I used to use the same tyres on my Escapade (since sold). Despite the use of sealant, I was never able to prevent leakage from between the split-rims for long. I used to run at 9psi, and never had any issue with them rolling-off the bead and deflating, even when tubeless; but I eventually fitted tubes due to the rim leakage.

I have these on a tailwheel Eurofox and yes lose some pressure - I have a nice neat and light hand pump with pressure gauge (and flexible built-in short hose) in toolkit on board now https://www.amazon.co.uk/dp/B08DVCNK4T/ ... 81_TE_item - I also run them at 15 psi which reduces roll resistance a bit

Does anyone have a UK source for tubes for these, for use on Matco split-rim wheels?

I tried to get tubes when I replaced my Turf-Glides. No luck. The originals had been fitted tubeless so went ahead and did the same. Not been a problem.
I do however take care to avoid any side loading when landing on tarmac due to the low pressure I run on. 12 psi. Grass is good. Tubeless appears to be a common method of fitting these tyres.
