"Tires Size Suggestion for 2007 Lexus IS350"

White 2007 Lexus IS350 Left Side View

What size tires do I need for my 2007 Lexus IS250/350? It’s my first time replacing my Lexus tires. I know the rear tires are bigger than the front two which is the reason why they cannot be rotated, but I am unsure what size tires I need. I don’t understand the tire label on the side and what is the best brand I can get that looks like low profile tires. I know its going to cost a lot, does anyone have any experience changing your Lexus tires? If so please assist me.

Answer: One of my friends works at Lexus and he says 225/40r18 88y in the front and 255/40r18 93y in the back, and they are expensive. And please don’t put cheap tires on them because you will have a road noise problems. I highly suggest putting Dunlop SP Sport Max or some Bridgestone Turanza or Potenza.
