Work it out, new tyre divided by old tyre multiply by current diff ratio. So if going fron 31 to 37 with 4.11, 37/31*4.11 = 4.9, closest to that is 4.88.. Going to 37 from 33, 37/33*4.11 = 4.6, closest is 4.56. Simple?

so i did alittle research and a bit of ringing around and was told that i cant get 4.88 ratios for the rear of a 100series. and that the way to do it was to put an 80series hemisphere into it. now i thought that 100s rear axles were larger than 80s. in my mind i cant figure out how this is supposed to work. can anyone shed some light.
