When I got new tires when my sxt was with stock wheels I put on the widest tires I could and they looked awesome and never had any problems either. I had the 195/55s. Now I have 16s and 205/50s.

 

You guys must have missed the part where I said changing the width of the tire but keeping the DIAMETER of the wheel the same. Deviations from STOCK WIDTH with the SAME DIAMETER. Also Darth I didn't say just because your tires are wide that your vehicle WILL hydroplane. There are a variety of factors that affect the tires ability to dissipate water.

My sxt has never hydroplaned ever and I was running with wider tires when my wheels were stock and still riding with wider tires so not everyone hydroplanes having wider tires.

 

Mustang GT's came with 17" wheels, and I have 17" wheels on the car? The width is different, yes.

I know you didn't say it will hydroplane, but you said it will have a stronger tendency. I've not experienced a tendency at all.

 

Look, try and think of it this way.

If there is a person wearing high heel shoes and a person wearing no shoes at all and they weigh they exact weight which one will exert a higher pressure on the ground?

Objects with higher surface are will be more tend to be more buoyant.

It might not be enough to feel a difference but it is a true statement.

Tires have "tread marks" in them to evacuate water from underneath them, unlike a solid...whatever?

Either way, now that this has gotten WAY off-topic, going to a 195 from a 185 is not going to be any different in any way, whether it's MPG, speedo reading or "hydroplaning tendencies."
