First off, I've read through pages on here describing tire sizes and such and understand it fairly well. With that out of the way here goes...

I'm in need of 4 tires as currently I'm running around with 4 different tires from 3 different companies (this is how I bought the car though so don't blame it on me).
What I've got:

LF: Michelin 225/60/R16
RF: Goodyear 225/60/R16
LR: Cooper 205/60/R16
RR: Goodyear 205/60/R16

Knowing that the stock tire size is 225/60/R16, I'm wondering if I should stick with that size OR if I should go with something different.
And before I forget to mention it I live up in Ohio so all-weather performance is a MUST.

So, I'm wondering if anyone could give me their opinion as to what size tire to get. I'd kinda like to get something a bit wider for more traction (even though it probably won't be much of a gain) and to make the car look a bit better, which is why I'm kinda looking towards something like 235/55's or 235/60's.

Also, I'm kinda looking in the $100-$120 price range. Over that is fine as long as it's what I'm looking for.

What do you guys think?
