Dry surface tire grip is mostly dependent on the rubber compound i.e. harder: less grip, longer life, softer: more grip, less life. Wet weather tire performance is dependent on the rubber compound and the water dispersion grooves in the tires. I'm not sure if the tire brand has an impact on given performance of a particular type of tire. Reviews can be subjective. Data such as G-loadings, road surface temperatures, road surface deposits, surface texture, tire pressures, tire temperatures, rubber compound, tire profile, water dispersion grooves, tires sizes, vehicle weight, steering geometry, vehicle downforce, suspension settings etc. My main question would be is there data available on the rubber chemical composition of each tire and a detailed breakdown of the tire's internal structure?
