It was Phil Lee again! Apparently the service conditions of an
aeroplane tyre and an F1 car are dentical to a bicycle tyre in his
Why do you think that water will behave differently if squeezed from
under one piece of rubber than another?
Maybe you think you've discovered the neutrino of tyre technology!
Both F1 and airliner tyres have massive wear rates compared to bicyle
tyres. Their tread life is measured in minutes rather than thousands
of miles. It is not viable to use a 3-dimensional pattern on these
high wear rate tyres as it is on a bicyle racing tyre. I've not got
HDTV, so probably wont see, but I wouldn't be surprised if a tyre
company for F1 started using the fine tread pattern as used on a
bicycle racing tyre as part of the pattern. It might just prevent
drivers spinning off in the first lap of a wet start.
errr... Nearly all Aircraft and many F1 tires have a tread patterns
and have had for years. Grand Prix/F-1 tires used treads from the
inception of Grand Prix racing in the 1920's. Aircraft have used
treaded tires since before the 1950's, to my personal knowledge and
undoubtedly before that.
As for wear rate, a 170,000 lb. (max takeoff) reciep. aircraft might
change tires once a year, if flying regularly. I'm not sure whether
you would term changing tires once a year as "frequent".
Re starting in the wet. F1 Technical has this to say: "With all the
power a Formula One engine produce the car can never generate enough
traction (grip). To prevent wheel spin the teams use an electronic
system called traction control to regulate the engines power whenever
it detects the rear wheels spinning."
In other words, your treaded tires (they already use treaded rain
tires) won't make a penny's worth of difference to a car that can spin
its tires in 4th gear on dry pavement.
F1 dry tires have been slick since the early 1970s, except when the
regulations banned them.
