I currently have 18x8 wheels (30mm offset) with 245-45-18 tires on a 2004 Maxima and the ride is too rough (of course the Chicago streets dont help). By they way, they fill the wheel wells perfectly.

Im looking to get a smaller wheel with bigger sidewall and was considering late model g37 17x7.5 wheels (45mm offset) with 225-55-17 tires.

Is this too big of an offset ? Will I need spacers ?

Or can anyone recommend an ideal size for a soft ride while still somewhat filling the wheel well and not looking too "tucked into" the car.

Thank you

I can't comment on your proposed alternatives.

But - IMHO - there's nothing wrong with wheels or tire size you have now. Ride quality is more a function of tire construction and suspension design than wheel size.

If your only goal is to get a softer/smoother ride you only need tires designed to perform in that manner. Forget the "Ultra-High" performance selections and look for "Touring" or "Grand Touring" tires. Check out TireRack.com for a selection of these types of tires.

If your goal is to get a higher aspect ratio (55 vs 45) to lessen damage caused by potholes, then that's another issue that I'm not qualified to comment on.

A telephone call to Tirerack.com might be a good thing. They appear to have qualified staff that can consult with you on these issues.

Thanks for the input. Part of the reason Id also like to get a smaller wheel is because of these horrible Chicago roads/potholes. A good set of new 18" tires runs about $600, while a set of 17" take-offs goes for about $900 (rims and tires).

Going forward, I also figured Id keep the cost of tires down with a 17".
