From the three different tire numbers you sent me, it looks like you have a 26.1" spare tire.

You can also do the math to find out what spare tire size cover you need. Take the first number and multiply by 0.0394 (205 x 0.0394 = 8.077). Then multiply the result by 0.75 (8.865 x 0.75 = 6.058).
Next, multiply by 2 (6.058 x 2 = 12.12). And last, add the wheel diameter, in this case 14 (12.12 + 14 = 26.12). That 26.12 is the tire diameter/height, give or take a fraction of an inch.

I linked our selection of 27" spare tire covers. You can get them in different designs like camo # 290-8757 or black # CAM45258.
