Re: Tire Valves

I'd just go with the rubber ones to be honest. The metal ones use an O ring and a nut which is more likely to give grief

Re: Tire Valves

Just stop by any tyre place and get regular ones. Only bought a pair yesterday and yer man didn't even want money for them. Gave him a few yoyos anyway.

Re: Tire Valves

You should replace your valves every time you replace your tyres.

Re: Tire Valves

+1 for keeping the rubber ones instead of the metal. Unless you go for the metals with the 90 degree bends, those are handy but still... replace them when you do the tyres.

Re: Tire Valves

That's a bridgeport 90 degree valve which is ok fitment in that pic as theres a flat section cast in the wheel. Not all have that, the base is flat with a rubber o ring keeping you inflated so fitting same to a wheel without that cast bit is hit and miss.

It's shocking the number of tyre fitters who don't do it though. I dunno whether it's because the customers are too tight to pay for them or what, but it makes no sense whatsoever to not change them with your tyres. It's only a few extra quid.

Re: Tire Valves

local suzuki dealer always puts in new valves for free on a set of tyres fitted, and in the city I think its like 5cuid to get them replaced when getting new tyres so its a small price and well worth it.

Re: Tire Valves

might be s stupid question but why would you change them at every tyre change ?
some sportbike riders go through 5 or more sets of tyres over the year and it shoulnd't be
that necessary I would think

Why not do it? You're there already and it costs cents to replace them. Those rubber things go through the same heat cycles as the tyre itself so if you manage to toast 5 tyres per year, you're definitely twisting that wrist and wouldn't make any sense to risk it for a tyre valve.

It's doing an oil change and not change the filter everytime... people in cages do that quite often. Sure, the filter might be able to hold a few more kms but for crying out loud, just change it!!

That's not a stupid question. My Suzuki service manual says:

"VALVE
Inspect the valve after the tire is removed from the rim. Replace
the valve with a new one if the seal A rubber is peeling or has
damage.
NOTE:
If the external appearance of the valve shows no abnormal con-
dition, removing of the valve is not necessary.
If the seal has abnormal deformation, replace the valve with a
new one.
"

My Bandit does low mileage, so the tyres usually last about two years.
I always replace the valves when fitting new tyres to this bike. The rubber stems
still look as good as new after two years.

The ZZR gets new tyres every year. I fit new valves with every second set.
