Default The Comfy Ride Thread (225/50/17)

Hey all,

So i've ran 19s and 18s on my ISx50 on NYC roads, and while they ride great when there were no imperfections, once the potholes roll around it just gets unbearable. I've downgraded back to the OEM 17s and now am even thinking about getting a thicker sidewall.

Has anyone ever run 225/50/17 (diameter of 25.9) on a LOWERED ISx50? I'm currently lowered on tein s-techs, with about 26" ground to fender. Trying to figure out if 225/50/17 will fit w/o any rubbing. Stock size is 225/45/17 (diameter of 25.0 inches)

Is your car AWD? Are you planning on the same size tire front and rear?

I ran 225/50R17 snow tires last winter on my stock height car. No rubbing whatsoever. Compared to a stock 18" front tire this is .77" bigger diameter, or ~3/8" bigger radius. Not a huge difference and I think, given that the width is the same, and you are on stock wheels it should work without any issue.

Yeah, car is AWD and going to run a square setup.

hopefully .77 will not result in some rubbing. I might use spacers to make the wheels more flushed too just for that OEM+ look. Did you find a change in ride quality with the bigger side profile?

Yes I did see a change in ride quality, but that would be like comparing apples to... llamas. When I bought the car last summer it was on OEM 18" wheels with stock sized staggered, mismatched, (Achilles on the front and Pirellis on the back), worn out, summer tires. Moving from those to square 17" snow tires was quite a change.

If you haven't considered it, you also need to look at the comfort of the tires you are using. Basically the higher performance tire you get the worse it will ride.

Thanks for the response. I went from 19's on achilles, to 18's on hankooks, and now 17s on mismatched tires. Ride quality is a HUGE improvement over the 19s but equal to the 18s. Granted its not going to ever be great cause its lowered, but at least some additional pothole protection would be great. Thanks again for the help
