River Wheel Co – “Shadow” Glide 115 x 30 (Black on Black)Wider Decks require more Ground Clearance to sustain an optimal Carve Angle so we created a wheel with a Diameter (D) of 115mm, a Width (W) of 30mm and a Profile Radius (R) of 24mm; specifically designed and recommended for Deck Widths of 5. 5 and above. With our 115mm Diameter, you will automatically gain 2 3. 5 on your Carve Angle* compared to a traditional 110mm Diameter Wheel and with our Flatter R24mm Profile you can expect a more consistent wear
