I have 40mm maxxis velocita tyres on wtb i19 rims. Two layers of tessa tape. These have held air and been fine. Topped up with Orange Seal Endurance often.
I’m getting intermittent air leaks. The rear will lose air pretty quickly (maybe 5psi and hour) above 20 psi.
What to tinker with first? Valves?
When fitting the valves it’s not easy to know how hard to force the rubber bung in. I presume they will split if forced too much?
It's always the bloody valves. Inflate to the max pressure, then tighten by hand. If it's still leaking maybe a small ride will do it, otherwise start again and be very careful doing the valve holes to avoid slits.

Any insight welcome.
