I have another thread seeking input on a set of wheels for my xs coupe, see:
https://www.myg37.com/forums/wheels-...eel-specs.html

A separate question - for those who have switched from a square to a staggered setup, what handling changes have you noticed? I believe that going with a wider tire in the rear, the grip in wet may suffer but dry handling will improve? Any thoughts?

Thanks!

 

I don't see how a wider tire would hinder the wet grip unless you went with a more performance oriented tire instead of an all season. More tire on the ground almost always means more grip.

 

That was my thought as well. There seems to be some debate though which surprised me - see:
Are wider tires more susceptible to hydroplaning? - Straight Dope Message Board

I know with snow tires you want narrower which makes sense to me. I always thought you would want wider in the rain though.

Thanks

 

Interesting points of view to say the least.. From what I got out of all of that is wider is still better, as long as the tread has plenty of area for the water to run through.

 

The understeer will be more noticeable than the changes in grip.
If you have adjustable sways, knock the front up a notch and you'll be fine.

 

Also wider tires are more prone to tramlining, especially going wider in front, so if you drive on a lot of grooved roads it's something to keep in mind.
