Thats why I went for xtra load and a higher speed rating. The car will do more miles on the road than track so it won't ever reach the limit where you would notice any difference in flex. Besides the flex will be less than the hankooks they are replacing and with slightly more rubber on the road I get better stopping power..
Its swings and roundabouts really. One size isn't going to make that much difference unless your name is Mark Webber
N.b.. Not dissing Hankooks, I love em, just wanted to try these 595's
*Update* Prodrive recommend and fit 225's as standard to their 7.5j rims, if its good enough for them, then its enough for me... Nuff said
