Although you need to journey to the highest, the main target for all-mountain biking is on descents. You want tires that grip nicely while you take turns at velocity and tires that may face up to reasonable impacts (search for larger facet lugs).
For downhill driving, you’re getting a raise to the highest, so that you want a burly, tenacious set of tires for gravity-fueled enjoyable. You want tires that may deal with some abuse, stick landings and claw their approach round turns.

Aspect lugs: Usually larger, they supply further grip in corners.
Transition lugs: Positioned between the middle and facet lugs, they enhance grip as you lean right into a flip; the result’s a smoother transition from middle lugs to facet lugs.

Race tires typically use a single compound that provides superior grip. However these single compound tires are normally worn out after just a few rides.
One widespread design answer for nonracing tires is a dual-compound rubber. They’ve more durable rubber within the middle to assist the tire roll sooner and last more. On the perimeters of the tire, the realm of the tire most important for cornering, is a softer rubber to supply extra traction.
