Goldspeed A6 Rolled Lip Rim feature an advanced design allowing a decrease in total air volume. This allows less air change during tire temperature change. The A6 is constructed of a special treated 6061 air craft aluminum material. Designed with dual reinforced rolled lips for suburb strength/durability. The A6 wheel features a durable gloss black powder-coat finish & comes with a reinforced valve stem and cap! The A6 10x5 wheel has a multi bolt pattern 4/144 & 4/156 and it comes in two different offset 4+1 & 3+2. This is the same wheel used by 5X Atv AMA Pro Champion Chad Wienen.
