OrionStang Posted May 6, 2011 Report Share Posted May 6, 2011 (edited) Ok, i'm getting new Motegi Racing rims 18x8 in front, 18x9 in back. I don't know how to size up the tires. Would 245/45 in front and 285/40 in back be ok? Will the sidewalls look the same height? To figure out the height in mm, do I divide the width by the ratio? Help please.

Azagtoth502 Posted May 6, 2011 Report Share Posted May 6, 2011 (edited) Well......mm divided by 25.44 gives you inches.

OrionStang Posted May 6, 2011 Author Report Share Posted May 6, 2011 Thanks, I figured it out. Front side wall woill be 110.25 mm tall, rear will be 114. So not a noticeable difference. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
