We do offer the 15x6 Lionshead Lynx trailer wheel with a 6 on 5-1/2 inch bolt pattern in gunmetal gray as part # LH37FR. This is as close to what you're looking for that we offer, as the wheel with all gunmetal wheel isn't available from our distributor.
The wheel is also available in a silver aluminum finish as part # LHSL311. view full answer...
