This is a nominal estimate but,
225 x .60 / 25.4 x 2 +15 = 25.63 inches tall
235 x .60 / 25.4 x 2 + 15 = 26.10 inches tall
275 x .50 / 25.4 x 2 + 15 = 25.83 inches tall.
295 x .50 / 25.4 x 2 + 15 = 26.61 inches tall
225 x .55 / 25.4 x 2 + 16 = 25.75 inches tall
245 x .45 / 25.4 x 2 +17 = 25.68 inches tall
See how it works, so your looking at a tire that probably can be around 27 inches without a problem. Interestingly most 275/40R17's and 245/45R17's measure in the manufacturers data sheets as specing out the same. Again though using the math gives you a nominal measurement, not the actual tire dia.
