About 25.68" tall.
0.45 x 245 = sidewall = 110.25cm
> Where 245 = tread width (footprint), and 0.45 equals the percentage of tread width, that is the sidewall.
110.25mm x 2 (for upper and lower sidwalls) = 220.50mm.
Convert to inches (of bowls)... 220.50mm / 25.4mm per inch = 8.68 inches.
Total height = 17 inches (rim) + 8.68 inches = 25.68 inches.
