I disagree - to a certain point, more pressure= more grip. I'm talking 205/60 profiles on 14x7" rims, and the difference between 30psi and 34/36. What you say is probably true for higher pressures though - if the tyre surface becomes convex, perhaps less grip from reduced contact pathc but better when cornering? you are right but also consider that these pressures are COLD pressures and therefore when under normal driving conditions these pressures increase. therfore your 34/36 tyre will reach about 40 or so once warmed adnd heated from driving which could end up convexing the tyre and reducing the traction that you have. this is why you see all tyre pressure rates at COLD tyre temps. therefore to maintain your optimal 34/36 pressure you need to fill them to 30psi when cold so that they get to 34/36 when warmed up. this is why it is essential to test pressures. i even go to the extent to measure the pressure at cold and then measure it again after a small run around the local neighbourhood. the problem is that alot of people (more mainstream drivers) see that their tyres are flat and pump it to 30psi. and then the next morning the get up and the tyre is flat again. thats cause the air inside has cooled and the pressure has dropped. ITS ALL TRIAL AND ERROR, also for your style of driving those rates are gopod for you and not so good for others cheers [Report message to a moderator]
