F1 tire blistering. The thinner rubber will be used at all races this year. The contact patch is wide and the cars are light. Of course the rubber formations of goodyear and bridgestone are entirely different. Pirelli explain the reasons behind tyre blistering and how this can effect the level of grip offered by the tyre. Actually f1 tires are dried and after they lost the liquid phase they disintegrate. When a tyre grains its like a bit of rubber gets ripped out and this then forms a ball but its still attached to the tyres and as they drive across the circuit i believe the effect is akin to what you see when someone is scooping ice cream out of a tub.
Blistering occurs when part of a tyre overheats causing rubber to soften and break apart in chunks and although it is not a new phenomenon in f1 it has been problematic at several races this season. I dont think youd see that same type of graining at nascar events. These issues mostly have to do with racing when tires are pushed to their limits when enduring enormous friction and pressure build up. Formula 1s official tyre supplier used special thinner tread rubber for last years spanish french and british rounds in response to the blistering several teams experienced during pre season testing. Im not a tyre person but ill do my best. The layers of the tire bend every revolution they rub against each other and this produces heat.
This heat moves outward and separate the rubber from the inner layers of the tire. Blistering was not a talking point. The teams had their first chance to test pirellis full tyre range for 2019 in last years post season test in abu dhabi. What do tire overheating graining and blistering have in common. What is blistering of a tire and why it happen.
