Why do people use really wide tyres on thier GT40s,when the basic laws of pysics tells us
1. The force of friction is directly proportional to the applied load. (Amontons 1st Law)
2. The force of friction is independent of the apparent area of contact. (Amontons 2nd Law)
Amontons' Laws of Friction Guillaume Amontons - Wikipedia, the free encyclopedia
If you choose a tyre that is too narrow then it will overheat, so you need to choose a tyre that is sufficiently wide enough so it doesnt overheat, but is there any advantage in having a tyre that is wider
Tim Kay, and Ron Earp whos races his Lola. have used 225 to 245/50/15 front, and 275/50/15 rears. The rears are approximatly 15% wider
Tom has used 225/50/15 front, and 345/50/15 rear. the rears are approximatly 50% wider
Would Toms tyres, give better lap times,assuming the tyres have the same co-efficiant of friction, or are the really wide tyres just for looks
Im also geussing the reason wider tyres are used on the rear,is because they are the drive wheels, and that creates more heat so a wider tyre is needed....
Im just trying to understand it...any comments would be greatly appreciated
