OK, the 245 (mm) is the width of the tire, or 9.65". The outer diameter of the tire is twice the section height + the rim diameter, and is 18" + 2 *0.75 *245 mm, converting all to inches 32.5"
You actually need to be concerned with cubic feet. You have to know how high you can stack to determine the floor area. Also can they be "close stacked" or do you need room to get around and get to particular tires? I'm assuming:
*You can stack about 8' high, that is a stack of 10 tires
*You can "close stack". If you need access room, allow extra
So you would have 400 stacks of tires, 10 tires high (96.5" or 8' 0.5"). Although the tires are round, you have to consider the shape of a hexagon around them for close packing. So the area of the hexagon, given the inscribed diameter is 0.866*d^2, or 915 in^2 or 6.36 ft^2. You need 400 stacks, or 2544 ft^2 MINIMUM. Remember, this is close stacked. If you need room to get to particular tires, you need more, probably AT LEAST 3000 sq ft, maybe 3500.
Also, I don't know anything about tires. Is stacking 8 feet high realistic? But considering floor area and height, you need around 3000 sq ft x 8 ft = 24000 ft^3, and that is probably tight.
