NSR 5201 NRS Zero Grip Slick Tires – 17 x 8 mm (4 Tires per Package) Fits 16 mm or 17 mm Front Rims • Hard Rubber Compound Improve the handling and electrical reliability of your slot cars with NSR Zero Grip Slick tires , designed specifically for low-friction front wheel performance . These tires use a hard rubber compound that dramatically reduces rolling resistance compared to standard rubber front tires. By minimizing grip at the front of the car, the chassis stays settled in the slot and the rear tires can do the work of driving and cornering. Because the front tires glide instead of gripping, more consistent pressure is maintained on the guide and braids , which helps improve braid-to-rail electrical contact and reduce intermittent power loss , particularly through corners. Features Size: 17 x 8 mm Fits rims: 16 mm or 17 mm front wheels Compound: Hard rubber low-friction compound Quantity: 4 tires per package Application: Front tires for performance slot cars Performance Benefits Reduces front-end drag and rolling resistance Improves cornering balance and stability Helps maintain better braid-to-rail electrical contact Reduces front tire scrub in turns Allows rear tires to provide maximum traction A simple but highly effective tuning upgrade , NSR Zero Grip front tires are widely used in competitive 1/32 scale racing with NSR, Slot.it, Scaleauto, and many other performance chassis.
