are there rare? only ever seen 14 and 15" ats cups but never seen 13's

and arethey worth any money?

any help would be great

Rare? Fairly. I tried to find some 13's in 5.5 or 6in wide but could only find 7s for ages. Gave up when i found another wheel.

But there's a reason they're rare - another word is unpopular. It's just not a desirable size, so you may have to hold out for those rare people who want them..

sure there were some on ebay recently. sold for £30!
