Fr710's arent really listed on TireRack......The Serenity reviews are kind of "Varied", individuals here seem to be knowledgeable........I have to get my CVT flushed on Saturday ($300.00), so the tires might wait for if the Firestones are OK, they are worth it! Wife has the final say

Well, if you have to, you can wait about 40 days until the next round of tire sales.

at 30m miles I was being advised to replace. Now at 35m it is a must. Any solid recommendations out there for replacements?

Hi, i see you are still obsessed with the T rating and 44lbs max pressure. The only thing Ford specifies is either 215/65/17 or 225/60/18. There are no specs for speed rating or max pressure. Since the max speed of the Freestyle is a governed 110, any tire with at least an S rating is fine. I, and several others, are now using a 225/65/17 with excellent results. The 215/65/17 is a little too small for the size and weight of the vehicle. The Serenities are very quiet, but much heavier leading to more unsprung weight.

Wouldn't the 225 size be bigger in diameter and cause your speedometer to be inaccurate? 28" diameter vs 28.5" diameter?

Wrong. We automotive engineers know that a tire with a recommended placard operating pressure of 34 psi on the Freestyle is not compatible with a 35 psi max sidewall replacement tire. Thats only a 1 psi margin. Its obvious. Thats why Ford engineers put 44 psi max sidewall pressure tires OEM on the vehicle. That was no accident its 44 psi.
 
"Since the max speed of the Freestyle is a governed 110, any tire with at least an S rating is fine."
 
As I've said before, the critical parameter is lateral stiffness, something a TR tire (OEM style) has more than an SR tire. Max speed is not the important factor, although a TR tire would be more tolerant of low pressure / high temp conditions before blowing out, a greater safety margin. Safety margin and ruggedness is important to some people; possibly not you, bruneau. Greater lateral stiffness allows better "L" obstacle avoidance maneuvers compatible with the suspension dynamics and CG position on the Freestyle, a problem seen in some SUVs in the past and corrected in more modern cars like the Freestyle, if you stick to the Ford specs of a TR tire. (See Toyota 4Runner as a bad L-maneuver vehicle, for one example.)

Yes. It corrected my speedo cal, actually.

So your speedometer was inaccurate until you put the 225's on?
How did you know?

You can check your speedo cal in two ways (then average results): First, time yourself between interstate highway mile markers, and, secondly, compare your speed to the display-radar set up in some neighborhoods. In my case, they agreed pretty well.
