The 19" Pirellis on my 2004 XK8 convertible have had the biscuit and need replacing .Expensive ,ride nice, BUT they don't seem to wear well. Currently 245/40's/19" front and 255/40's/19" rear.
With my other vehicles I get very good mileage by rotating the tires at regular intervals. I would like to replace the tires with 255/40's/19" all round. Has anybody used 255/40 /19" on the front ,and if so has it .........
effected the ride ?
