Being honest, I have always struggled to get accurate tyre pressure readings. Presently I have two gauges - a very old pop out one, and a newish Ring digital type. Neither fit onto my V-strom 650 valves well - the rims don't have much distance from the wheel centre, and the discs/chain ring gets in the way. I have bought angled valves but even with these it is a struggle and I lose so much air in the process of taking the readings that by the time I do get one it is too low and I have to start the process again. Any comments!
