claypole1360 6 Posted November 24, 2013 So i have a choice. On my standard XS rims you should fit 165 70 13s, i like the look of the reviews of the Kumho Solus kh17, but is there any benefit from going to 175 65 13. It equates to Half a mile an hour difference at 70 so that isn't an issue but will it improve the grip or ruin the handling? Calvin. Share this post Link to post Share on other sites
