Title: Tire valve stems
Post by: mrmike on February 26, 2025, 12:11:04 PM
I'm putting Michelin City Grip 2 tires on my People S 150 next month. Are there different tire valves available that make checking tire pressure available?.

The right-angled ones I find can be awkward.
The long ones flex too much for my comfort - and I worry about not having room for the air hose.
Therefore - I like the short ones.
But DO insist they install new ones!
....AND check the stem before you walk out! I did not find that the tire tech had torn the new valve stem badly and it leaked air if you just touched it - let alone try to put air in it!  (now I drive the wheel 30 miles to a Honda Power Seller)

Trouble was - I'd already installed the wheel on the scooter!
Paid the bill and even tipped the kid!

I use the right angle valve stems on my Triumph, but like Stig, I find a scooter wheel is too tight for them.  Use the stubby stems and buy either an adapter (flexible) or a suitably equipped pump.

in the past, I have always insisted on new stems, but now, with the tire pressure sensors on my AK550, and my new to me Nissan Frontier, what is the deal on routine replacement ?

that got me thinking...and doing a search turned up a lot of info. Yes, the valve stems are replaceable on TPMS units, along with a sealing o ring and apparently the TPMS sensors themselves need to be resealed after a certain number of years to prevent leaks. Tire installers now charge for TPMS 'reseal kits'..
