Dry surface tyre grip is mostly dependent on the rubber compound i.e. harder: less grip, longer life, softer: more grip, less life. Wet weather tyre performance is dependent on the rubber compound and the water dispersion grooves in the tyres. I'm not sure if the tyre brand has an impact on given performance of a particular type of tyre. Reviews can be subjective. Data such as G-loadings, road surface temperatures, road surface deposits, surface texture, tyre pressures, tyre temperatures, rubber compound, tyre profile, water dispersion grooves, tyres 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 tyre and a detailed breakdown of the tyre's internal structure?
