Just a small warning: "205/0QR14 D" on the
Sizes and Pricing page is not a tire size, so the people who assembled the information at the Tire Rack for this line of
tires did not know what what they were doing, or were not careful. The Tire Rack is apparently a reputable company, with lots of good information posted on their web site, but any information from them specific to this tire is suspect. All three sizes are similarly incorrect.
I was guessing the incorrect size might be intended to be something like 205/80R14 (with a "D" for load range), although a 205 mm wide 14" tire would more commonly be a 205/75R14. The "Q" happens to match the speed rating, so it might be 205/80QR14 D, using the old scheme of placing the speed rating before the radial designation. Check Tire Rack's
specs page for the same tire, and now the "0" is gone... so it looks like a blank on one page just became a zero on another. It's pretty bad when you have to guess the size of a tire you're considering buying.
For a more authoritative source of information, check out
Kumho Tires. As discussed in the
Casita forum topic, the 857 is a commercial-service tire, suitable for trailer use (as well as trucks and vans). The actual size of the 205-width tire is 205R14 - the aspect ratio is not specified, and is about 80 (from the dimensions), so the Tire Rack people
were perhaps trying for "205/80QR14"; from their own
description page it should have been 82 series, or 205/82QR14. There is no indication on the Kumho page of the Q speed rating, but the load capacity does match the 109 load index assigned by Tire Rack (they call it a 109/107Q, presumably meaning 107 at Q speeds, and 109 at some lower speed).
In the end, if you want a high-pressure, high-load tire in this size range, the Kumho looks fine... I just suggest going to the best source for reliable information.
