What is a tire Siper used for?
Product Description. Sipe tires quickly and effortlessly while maintaining precise control. Siping can greatly improve traction by allowing the tire to reach and maintain optimum temperature. A locking lever and blade clamping screw secures up to 13 blades in the head assembly.
How deep can you groove a tire?
Angled grooves will result in a combination of increased side bite as well as increased forward bite. Unlike siping in which you should go no deeper than 1/2 the depth of the tread block, grooving can and generally is the full depth of the tread block.
Is Siping good for tires?
Tire siping improves traction and braking, makes for a smoother ride, and prolongs tire life. Siping won’t reduce tire performance in any way. The tire tread retains its toughness due to the patented spiral cutting process. This leaves uncut areas known as tie bars intact, keeping your tread strong.
How can you tell if a tire has been retreaded?
Look for differences in texture and density between the tires’ sidewalls and their tread. Retreads may have faint distinctions. Check whether the treads are darker, for example, or slightly rougher to the touch. These differences are rarely significant, but they do appear.
