There is much more to these than 10 mm of additional width. You also need to consider weight and rotational mass, as well as the compostion of the tire.

Contact patch size is more a function of the weight placed on the tire and the air pressure in the tire. The shape of the contact patch changes and that's what is significant when it comes to snow and water. Some empirical data I've seen indicates that contact patch size is slightly bigger with wider tires but the increase is not significant.

but also more weight/drag, which a 2.8 or 3.0 don't need really. Bottom line, I'd tend not to do it again.

in any event, as long as all 4 change, it works very well. Better than stock IMO. Your gearing will be about 1.2% higher, and your speedo will read correspondingly lower. Big whoop. The tire swill have a higher load rating, which makes them more resistant to wheel damage on potholes. They may stick better but that's probably negligible.

Section height ( sidewall height) is defined as a % of width. So if you change width, you change height, unless you then LOWER the section % - say from 55 to 50. But then its too SMALL.
Read up on DOT specifications, from sizing to load rating to quality grades, etc.
Then you can do the math easily with high school math.

In a -1 ( 16") configuration but oversized, as you are contemplating, from a "stock" size of 235/50-16 to what I bought: 245/50-16.
