Now that I have 16" tires I am assuming I will have an issue if I have a flat and need to put on the 15" space saver spare. Will the vehicle see a difference in wheel? speed between the 15 and 16 inch wheel? Anyone else have advice on what to do? Is there a 16" space saver spare for the Escape?

What size is your old tires, vs. new? The wheel diameter does not make a difference. On the late models, the temp spare is actually 17". Figure out your tire diameters. If they are within 1/2" or so, the spare should be OK. As Squishy is hinting, if you have 4wd, it would be best to keep the diameters equal.

My Escape is 4WD but not AWD. Old tire size is 225/70R15, my current (new) tires are 235/75R16 which if I am correct calculates to a diameter or 29.87796 inches.
The spare is 135/90 17 which if I am correct calculates to a diameter of 26.56692 inches. That gives me a variance of 3.3 inches for a diameter and 1.65 inches variance for the radius. Can someone verify these figures for me? If these numbers are correct will this cause an issue? If so. any suggestions on a standard space saver spare that will fit and solve the issue
I also know my speedo is reading slower than it should the, OEM tires have a revolution per mile of 736, the new tires are 675 revolutions per mile. That gives me almost a 10% error. At 60MPH actual speed is 65.66MPH

The spare won't work, and you may not be able to get one that does depending on the year of your Escape. 2001-2004 Escapes will not be able to fit any 29.88" spare tire. You should be able to fit a full-size under a 2005+ Escape, and I would just get a used tire on steel wheels instead of trying to find a compact spare. If you have one of the earlier models, you can get a can of tire sealant and carry a 12-V compressor, or you can get a roadside assistance plan.

By the way, no Escape has ever had a 4WD system. They market it in such, but the Escape, like most small SUVs, has an AWD system much like you would find in a sedan. No transfer case, no low-range, no locked 4x4 (not even the early Control-Trac II systems, the switch is another "trick"), and no 2WD-only mode. Notable exceptions are the Jeep Liberty and Nissan X-Terra.
