Silver tire valve caps
Lost one of my valve tire caps the other days and I have been looking at Anodized Alloy Valve Caps. But I have read somewhere that vehicles with TPMS should not use metal tire caps, is this true. Also, where can on e find the silver colored, plastic tire caps that the Outlander uses. I have looked everywhere for them and all I find is aluminum or black plastic caps.

This is a service bulletin from Mazda about TPMS. (I know, not Mitus, but they both start with an M )
"Some aftermarket valve stem caps are made of brass or steel or have thread inserts that are made of brass. Examples of these types of aftermarket valve stem caps are shown. When brass and aluminum are together in such a
condition as this, galvanic corrosion occurs between the aluminum valve stem of the TPMS wheel unit and the brass threads of the valve stem cap. This corrosion can cause them to fuse together, becoming difficult to remove by hand. Then when more force is used to remove the valve stem cap, the aluminum valve stem of the TPMS wheel unit will break off and the TPMS wheel unit will be to be replaced.
This service tip is to aid in informing customers of the damage that may be caused to the TPMS wheel units by installing these types of valve step caps. When you encounter this concern, please advise the customer to use aluminum or plastic caps ONLY. Also, ensure that the caps they choose to install DO NOT have a brass thread insert."
Hope this helps

If you spray them with silver, try hitting with a clear coat. When I was young, my dad and I restored an old Case tractor. Rims were silver. The silver we put on was really bright. We hit it with a clear coat and it kinda dulled the finish down just a bit. With our rims, it may look a bit much to have bright shiney silver valve stem caps with dulled silver wheels.

I used the chrome caps and they corroded the threads. I went to black plastics and spray painted them silver
If you wanted to go with the metal caps, I'd use some kind of thread lubricant/anti-sieze such as for spark plugs to prevent a reaction..but I'd still go with plastic
