I currently have the 235/45/18 Bridgestone Turanza El 400's in an H rating----ugh.
I really want something quieter, smoother, and safer that will maximize MPG's as well. I drive pretty easy as well, especially since I am hauling my 1 year old son around.
From what I could find on Tire rack, The tires I have weigh 24 lbs and tread width is 8.1". I could not find overall diameter specs but similar Bridgestones are either 26.3" or 26.5"
All of the 225/50/18 seem to have an overall diameter of 26.9" Is this little bit going to affect my speedometer? Is this little bit really going make a difference in ride and Gas mileage? Even worth the hassle of changing sizes? I would like the idea of filling up the wheel well a little with a taller tire but is .6 inches really going to be noticeable? The 225/50/18 seems to be a little more expensive as well.
The tire's I am debating between are the same ones everyone else seems to be debating between - Pirelli P7, Conti Pure Contact, and Michelin MXM4.
Conti Pure- 235/45/18 - V rated - 24 lbs, 26.3" diameter and 9" tread width
Pirelli P7 - 235/45/18 - H rated- 25 lbs, 26.5" diameter and 8.4" tread width
Michelin MXM4- 235/45/18 - V rated - 26 lbs, 26.3" diameter and 9.2" tread width.
Michelin Defender - 225/50/18 - T rated - 24 lbs, 26.9" diameter and 9.2" tread width.
Michelin MXM4- 225/50/18 - W rated - 25 lbs, 26.9" diameter and 7.8" tread width.
The Pirelli P7 is intriguing me the most because of the H rating. That should mean a little better ride than the V because the sidewall is not as stiff correct?
I have also read that the more tire to the ground, the worse the MPG's. Most of the replacement options I am looking at have a wider tread than what i have. Is it so minimal that it will not even matter?
I have read probably too many reviews here, tire rack, and other places and just cannot decide. The good news is any of the replacements I am looking at will be much better than what I have based on the information I have read.
I keep going back to the Michelins based on the tire rack review in the link below because it seems to be the best riding and quietest of the 3. But this review also used the V rated Pirelli and not the H rated version?

Decisions, Decisions, Decisions. As you can see I am over thinking this but whatever I buy, I am going to have to live with for at 50k miles.
Thanks in advance for all replies and suggestions.
