Trying to figure out if I need to order center caps with a 20” All Terrain wheel if I already have bought 21” center caps.

Anyone know for sure?

I think so. I picked up a set of 20” wheels with center caps and tpms a few weeks ago to replace my 21” wheels. I had already bought center caps for the 21s and the tire shop put those caps in the 20s when the installed the tires. The caps I bought with the 20s at still in the packaging and the ones from the 21s haven’t fallen out of the 20s…yet.

Do you feel any color difference is bugging you to the tune of $150? (They want $150 after tax for 4 20” center caps)

I know this is me being really cheap, but the whole conversion from 21” wheels to 20” is a hassle.

I never noticed the difference in colour, hard to tell but looks like the 21” caps are darker…slightly. When they are mounted it’s next to impossible to see the difference due to the rim being slightly concave and the cap being slightly convex.

Probably not worth the expense. Can always go find some mud then you’ll never notice the difference…

Thanks for the Amazon suggestions. I already have 21” center caps so I’m looking to reuse them.

They are the same. i recently bought four 20" AT wheels from Rivian and was surprised that there were no center wheel caps so i tried the ones i had bought for my 21" wheels with the aero covers. Reason for that anal move is that perhaps i'll leave those covers off the 21" except for when making long (200 miles +) trips. The Rivian cpas are nice but ridiculously expensive. There are other ones available at fraction of price.
