Should I change gears or not?

The 295 and 225 are basically the same and the 275 are taller 26.6"/26.4"/28" there effect on rear gear .90/.91/.86 x 3.23 = 2.91/2.94/2.78 looks close enough to me. But here's with 3.55, .90/.91/.86 x 3.55 = 3.20/3.23/3.05. So your overall ratio is 2.94 now with the 3.230and 225 the 275 and 3.23 be 2.78 and 3.55 be 3.05 you could go with 3.55 if you choose they be closer but slightly deeper.

Edit* had a mistake fixed now
