Anybody have Kumho MX's on a coupe w/ oem 18s
 

If so, what sizes are you running. I'm not interested in a 275 rear. I would like these tires as my stocks are starting to go. I STFA, but I just found a lot of arguing on if 275 will fit and no specifics on these tires w/ oems.

Based on this, they don't have anything that would match the stock 18's. Also keep in mind that the Khumos run a 1/10" lower tread depth. I'd like to see how they hold up to other tires if the other tires were shaved 1/10 of an inch first to match the tread depth. Their great out of the box performance may partially be attributed to this. Still a good bargain tire, but they don't have the OEM sizes. You'ld have to run slightly lower aspect ratios.

Thanks for the info. Unfortunately, I was hoping all of my research was wrong and they had a tire in OEM size. What tire size (if I did go w/ the MX's) would be a safe application without voiding tire warranty, messing w/ computer/speedo?

Looks like I may have to shop for only oem sizes. Back to the STFA for me to find a quiet, performance tire.
