Generic name for place that sells rims. "dealership" is usually used when selling whole vehicles, not parts, so its unlikely to be used paired with rims. The domain name does not appear to ever have been registered before, meaning nobody ever needed it even though buying/selling rims has been around for decades.
Sadly I think this domain has very little value.
ps - You might want to familiarize yourself with the expired domains list. You are more likely to find a domain that will sell than doing a random hand reg.
