Project IS-F: Getting New Shoes with Nitto Tires
Project IS-F is a real daily driver, driven every day by a little old Asian lady back and forth to work. On weekends the car also hauls the family along, fast. The car gets a lot of miles on it and day in and out wear and tear.
Our project car previously sported a set of Nitto NT05 ultra high performance dry weather tires in 275/35-19 for the rear of the car and 245/40-19 for the front. We kept the same front to rear stagger in width but ran a taller tire in the front to keep the front of the car from being too low so Asian ladies wouldn't smash the air dam on everything.
The NT05's had a lot of dry grip, a decent ride, were fairly quiet on the road and actually were not that bad in the rare California rain storm. What they did do was wear out fast. Our tires were pretty well worn out after only 17,000 miles. Although this seems fast, our OEM Michelin Pilot Sports wore to the cords in just 15,000 miles.
It seems like the IS-F has a big appetite for tires even when aligned properly with a mild street setting. It is a heavy car with a lot of torque and power with a multi link suspension that employs an aggressive camber curve.
It was time for a new set of tires and we decided to to try another tire from Nitto's product line up, the Invo. The Invo is still considered to be an Ultra High performance tire, just one that is less biased toward dry grip and optimized for more all around grip and a little longer tire life. Considering that our IS-F is used a a true daily driver in all weather conditions, we felt that this might be a better choice in a practical sense.
