Modern tires are no longer constructed this way but the term ply still refers to a tire’s equivalent load rating. A taller sidewall makes for better traction results from airing down off road, and modern overland tires typically have a reinforced 2-ply or 3-ply equivalent strength to help improve performance and puncture resistance while aired down.Įarly tires were built with multiple layers (or plies) of cotton fabric that provided their strength and load-bearing ability. The sidewall is the side of the tire that does not make consistent contact with the terrain. slinging mud or water) as well as gravel ejection.
Tread Grooves assist with cleaning during rotation (e.g.
#BEST TIRES FOR A TIME OUT CAMPER PATCH#
Tread blocks are the raised sections of tread that make contact with the terrain and provide the traction patch or surface that your vehicle’s weight is distributed on.Įqually as important as the tread blocks are the grooves or valleys between them. This is why we do not recommend the aftermarket tire siping services offered by some tire retailers. Sipes are the small grooves in larger tread elements that provide increased traction in mud, snow, ice, and rain - typically the more sipes the better the traction (up to a point, over-siped tires have increased wear and on-road performance issues).
