Hi,i've got a is200. when i bought it, it came with dunlop sp9000 215/45/zr17 tyres...ive had to change the tyres twice due to nail/screw being in two different tyres within 5 months. i was starting to think if these were not as good as the bridgestones or michelins. has anyone else got another brand tyre in theirs apart from the dunlops, or changed from dunlops to something else and thought they were better? let me know. thanks
