i prefer to stay in same size as OEM 215/50 R17, few of my friends are running 18" with 225/45 R18 and 235/45 R18. i was running 215/50 R17 n since last year m on 225/45 R17 due to my turbo civic has been tuned n need better grip. Btw all tires i get from Zafcom as well.
if you want to get more comfort due to bad road in Khi then you can try 215/55 R17
PS: MC5 is old pattern design now, i would suggest MC6 but those are not available in the mkt.
Toyo Proxes CF2 got good ratings.
