Plenty of people have put 245/40/18 on but that makes the tire slightly taller. 265/35 would be the next closest height but it seems like it might be too wide from what others are saying
Did you actually go with the 245/40-18? And if you did, did you do another gps measurement reading? I’m thinking of putting on the same size on my Si when I put on the summer tire soon.
Super fast reply to a stale discussion. Thanks man! Made the right decision to get into the Si family, you people are great. Anyhow, I’m really thinking about going for the 245s. The gas mileage shouldn’t suffer much if at all. I’m averaging mid to high 30s in the city, so any drop should be small and easily absorbed. There’s just something anemic looking with the 235 stock tire, especially from behind, and think a bump to 245 could fix that. Then again, it could be the all season rubber giving them that small illusion, and summer rubber could look wider. 245s would also fill out the wheel well a smidge. I’m looking to change the tires over to summer after I get my first oil change, and sell the Goodyear a/s. It’ll take me at least 4 years to climb to 50000 miles at my rate before I need new tires, so changing them sooner rather than later makes most sense for me
Still the same 235/40s for me, so I can't say yet if a different size would help. But I still wince when crossing some bridge joints, and I also still notice that my winter set of 215/55s on 16" steelies is more plush-feeling.
Nice. I’m looking for more comfort and filling out the wheel well some more. For all season tires do you think that would be a good idea with the ratio you mentioned?
By "filling out the wheel well", you're talking about tire width, right? Because going with a larger-circumference tire will start to mess with your speedometer.
