“Lots of times their tire selections are more for the “looks”, right?”
Tread patterns have varying degrees of purpose….more forward bite, more side traction, noise reduction, stability within the tire structure etc. There is a whole world of things that define tires and tread design. Not to mention the compounds that are used on the “rubber” part, all the way down to wether or not they use a biased ply or radial….. and if radial wether its traditional steel belted or using a different cording. Ever wonder why 99% of motorcycle tires are directional? Not just cause it looks “cool” but it gives the engineers a better degree of traction control and stability. Easier to predict how something is going to react to abrasion and heat when going one direction the having to figure in both. Look at Bridgestone and Michellin…. both are offering a 3 compound 3 section tread on their tires. A harder compound in the middle for life of straight highway riding softer on the edges for maximum (for that tire) traction in turns. These are not just sales points (though good ones) these are actual facts of the product and need.
