The Michelin Pilot Sport All Season 4 is an ultra high performance tire developed on the track and proven on the street. It has an asymmetric tread pattern that ensures even heat and traction distribution for a long tread life while providing more outer shoulder lateral grip and maximum levels of silica to stick to the pavement. Full depth sipes improve the Pilot Sport All Season 4's traction in wet and snowy condition and helped it become the first ever all-season tire chosen by Chevrolet for the Corvette.
The 255/45R21 Michelin Pilot Sport All Season 4 has a diameter of 30", a width of 10", mounts on a 21" rim and has 692 revolutions per mile. It weighs 32 lbs, has a max load of 2094 lbs, a maximum air pressure of 50 psi, a tread depth of 9/32" and should be used on a rim width of 8-9.5".
