The 2007 Jaguar XK will use the Dunlop SP Sport Maxx ultra-high performance tire.
Size 255/35R20 will be used on the front and size 285/30R20 will be used on the rear, say Goodyear Tire & Rubber Co. officials.
Benjamin Willot, director, original equipment sales and marketing for Dunlop in Europe, says Goodyear and Dunlop worked together for more than two years to fine-tune the tires for "fluent handling, responsiveness and road holding."
