Should I change valve stems when installing my new tires?

When I used rubber valve stems I would inspect them and change if warranted. Same difference with the angled valve stems, I inspect the rubber gasket and change the stems if needed. So far I have had the same angled valve stems for several tire changes and rubber gasket is still in good shape.

I had an issue with a valve stem replacement when getting a new rear tyre fitted. They fitted a new valve stem that was slightly longer and I was not informed about the stem replacement, nor did I want it replaced. When I fitted the wheel back on the bike I could hear a faint ticking sound while riding, eventually discovered the new slightly longer stem was hitting the brake Caliper. Had to remove the wheel, take it back and have a correct stem fitted.

I agree with Duc2V4 and FJ12Ryder, have never had an issue with valve stems on my cars or bikes, simply replacing valves stems just on spec is overkill IMO. It's a personal choice!

Cheers.

Yep!

 

 

These (or ones like that one) will stay on. It is the "vertical rubber ones" that are replaced each time. This as per my "tyre guy" who is a one of the larger retailer of mc tyres

Yes, because it is the rubber stem that degrades over time, not the o-ring seal.  If your valve stem isn't made of rubber, there's no problem that needs periodic "solving".

Every time I change tires...If I have traditional stems (like stock) I push it over sideways.  If I see cracking or dry rot, I replace them.  If I'm on my game, Ill order angled stems and put those on...those, if they are Italian, have a buna-n o-ring (doubt they are viton) which should last a long time. If you buy them from China, lord knows what kind of o-rings they are or how long they will last. Those O-rings are replaceable as well.

 

If you buy OEM stock o-rings, youll be buying a known quality product, well spec'ed.  the angled ones from Curvey Girl are Italian, quality products.

Same here. Love them.

 Me, too.

 

Don't think I paid that much for them, but they were a couple of dollars more than rubber. The minor increase in cost over regular valve stems is worth it. Especially checking pressure on the front tire.  They're plenty light, too. I didn't even need weights on my last balance.

I bought genuine Ariete stems on Ebay for $17 IIRC.

That seems like a great price. I think I paid ~ $25. And I keep a spare pair on hand.
