Hello,Can they be used with stock 15" wheels? Most custom caliper covers state they require 16" or larger diameter wheels.
Thank you for reaching out to us.
Per the manufacturer these can be fitted with the all stock wheels.
We installed them on our smart car with the 17" Lorinser Wheels, so cannot speak to first hand experience with installing them with the 15" wheel.
What we can do is if you would like to order a set to try them out, and if for some reason they don't work we will be happy to take them back. Just be cautious when fitting the wheel to not damage the covers so they can be returned.
As always if there is anything else we can do, please don't hesitate to give one of our Team Members a call at 512-982-9393 or 562-981-6800 and they will be happy to help.
