Heard great things about the Yokie A539's... when I got my car there was one tyre nearly on the canvas, one new utterly unknown plastic looking (remould?) and two badly worn (toe-in) Toyo's.
Wanted to get run-flat 205/45R17 Dunlop SP9000's, but was advised that it's screw up the balance of the car on the 45 profile (not dropped the suspension yet) and it'd also put the speedo / odometer out.
Ended up going for 205/40ZR17 Toyo Proxes T1-S. Very happy, but wouldn't mind a slightly softer ride as the cab can be pretty jolty somwtimes... might have to look at the 45 profiles again once I drop it (the SP9000 or A539's).
