Tire rack has a very nice selection, maybe start there? and with 18's your tire size should be P225/50R18. What's nice about that size is you will have a lot more selection for all-season tires than the OEM 19s.Hey guys, does anyone know if there are 18 inch wheels similar to stock 19 inch wheels that that I could use. I would not want them to look too mody. Thank you.
