I purchased them from the dealer. I just googled them and i came back with this result.

I'm sure you can find it other places.

Look up some bicycle stores... you can find all sorts of valve caps that'll work fine and they'll be cheaper and much better than the crap you can get from dealers and auto shops.

Some people at a Honda Ridgeline forum have the same issue.

They mentioned a Victor product which I think is this one.

Found them at Checker but silver and online only.

Here is a simple chart for estimating the dissililar metal (galanic) corrosion for metals that another poster mentioned. Chrome and aluminum pretty close but brass (which I believe some caps are made of) and aluminum are a little further.

Based on earlier posters anti theft suggestion.

Pretty cool find there Clorox. I guess people are just as concerned with someone deflating your tire as they are wih simple cap theft. Great, now I have one more thing to worry about when I am at work.

I ordered a set of these from Spin-Caps this morning...

I'll post my review when they get here.

Our valves are aluminum not rubber like the others.

Yeah... I know.
There's a good chance these won't work, but I'm giving them a whirl anyway. (I'm hoping I can use the caps without the valve-stem sleeves.)
They'll be going on the summer wheels, if they fit.

that happened to me, with the good, and the ugly... so i decided to stick it to the man.
and jacked a set off my loaner car... since then (knock on wood) im good.

ya i HAD the nitro filled caps when i got my car from nashville, people in texas dont seem to understand that nitro filled tires are good,

Okay, my caps came today and I'm very happy with their apparent quality. I can't put them on my wheels yet, as these are for my summer setup which is still sitting in the basement, waiting for winter to **** the F off....

Sorry... lost myself for a minute.

I emailed the company and told them that I had TPMS valve stems. I was asking if I could use the caps without the stem sleeves.
Turns out, they sell "Chromies" which are the caps only... and they also sell "Chromies XLs" which are the stem covers and caps.
I ordered just the caps and here is what I received.
You get the four caps, either in chrome, or in the color of your choice. (I got the blue ones) They also give you two keys, which fit over the caps and a pin fits into the cap to tighten them up. The outer sleeves spin super easily, so these are not being stolen unless someone squishes them with a vise-grip to get them off.

Worth the $20 in my opinion.

Looks good.

Lifetime waranty too.

They recommend hitting them with a couple drops of WD-40 twice a year and other than that, they're good for life.

I just asked the dealer if they had some extra ones and got some. So far so good here too.

Move out the Hood!!!!

Oh, there's a helpful comment.

I don't live in "the hood" but I also don't have my caps being stolen.
I do know,however, that if you have nice caps, the chance of them being taken is much greater.

I'm far from a thug, but when I was a young kid, one of the things to do was to cruise around on our bikes looking for caps to swipe... so we could put them on our bikes.

I guess it's karma. My childhood innocence is coming back to haunt me.

If you had the stupid blue ones that oddly came on my G you would have no problem!
