Colors: Black, Sliver, Chrome Bolt Circle: 4.50", 4.75", 5.00" Wheel Size: 15" X 8" New tooling for 2006 has enabled the most widely used 15x8 wheel in IMCA and WISSOTA racing history to become even more popular. All center discs are formed out of HSLA steel for superb strength and durability. Now the 52 Series wheel has more accurate bead seats and lower run-out than ever before. The bead hump still has a knife edge on it to grip the tire and lock it on the rim. No other approved wheel will keep your tire on the rim better than ours. These wheels are designed to be both strong and energy absorbent, saving you money in the long run. NOTE: Available stickered as IMCA or WISSOTA. This item has a special shipping fee of $7.99ea and all orders will be charged a $10.99 handling fee. For more information see our shipping page.
