Tread pattern – Its affect on the over all grip of the car. Thread pattern – Its effect (...sorry not affect )on the over all grip of the car. As seen in F1 ,they use grooved ones on a dry day and wets in wet .
Accordingly its evident that the latter provides more surface area of contact and hence higher the grip . Why aren’t we experiencing similar properties on road ? Lack of grip is clearly evident when we attempting for 1st gear – 2nd Gear wheel spin . In my case I had tested (in a perfectly flat road with very less particles on the road in summer ,didn’t check the road temperature though ) a GIII potenza and I found out that worn out ones give better wheel spins and in fact they slide a lot more under hard braking again emphasizing the fact that they are not gripping properly . Shouldn’t this be the opposite ? I mean a worn out tyre pattern should be giving better grip right taking into account just surface area of contact theory ? I am not talking about rubber compound whether its soft or hard .
Just a deviation on the same topic . Which tyre do you feel is the most suitable for wet roads . A few days back I tried testing three of them in a water logged area of a road approach speed around 60 kmph. I tried on Brigestone S322 , GIII and Yokohama FES XXXX . The car shod with GIII was pulled to a side whereas the other two tyres kept a near straight line . Which tyre you have tried feels the best in wet ?
