So, I lost (well, the wind blew them away) two of my tire air valve caps. Are all tire valve caps a standard size? Or do I need to get specific ones for the Volvo 850? And, any suggestions of where to order them online? Thanks!

 

a tire valve cap is a tire valve cap. Any auto parts store will have them for like $2/ pack of 4. or you can get the fancy chrome ones for like $5 or so.

 

Cute...

 

if you want to lose them and repeat the process.
