Hello thebestgang.
The capacity in your Expedition is 19.4 US quarts.
Depending on your location, a 50/50 mix of coolant and water should be used.
In northern climates such as here in Canada I use a 60/40 mix.
I hope your repair goes well. Thank you for using FixYa.

SOURCE: What tires can fit a 1999 ford expedition xlt
I believe it will fit. If you go to DiscountTires.com you can use their site for alternate tire sizes. Especially handy is the feature which shows you the Speedometer error for different size tires. The site will also show you recommended and popular substitute tire and wheel sizes.
The 1999 model had a 265/65/17 as an alternative. You may want to ask the Tire store you intend to use if they can reconfigure your Speedo to be accurate. Some of the Fords can be done electrically without changing Speedo gears.
I did something similar by going from a "60" series to a "65" series in the same width. On my Grand Marquis, I gained 5% mileage improvement, but have to watch Speedo until I get it reconfigured. I hope this helps to answer your questions.
