if you go wider than the rim is intended for, you will lose cornering cuz its not good for the tire.... Kumho Ecsta is a great tire, Toyo Proxe is also good, i have Sumitomo Srixon4 on mine but my rims are 185-60-14 (keep it stock :-D) they are good see if they come in your size too (i got mine from tire rack i think or discount tire direct)
