M9540 gear ratio

[AllDodge]

Anyone know what the gear ratio is for the M9540DHC24 SN 86399 ?

The tire sizing is not matching up so trying to verify other possible issues. Have read the M7040 has a 1.438 ratio, but if I use that with my tires this would mean real trouble.
Rear 18.4-30 Front 12.4-24

Don't know gear ratio but 18.4X30s are compatible with 12.4X24s ()R1s).

I am assuming the same even though the manual shows

For the M8540 and M9540
Front 12.4-24 or 360/70R24
Rear 18.4-30 steel, 16.9-34 cast iron, 480/70R34 (this tire is 18.4-30 and has 187 inch circumference)

I have cast wheels and manual list 16.9-34

I'm sure things are ok, but would like to verify everything so nothing is left out

Figured it out its 1.3529

My M9960 (replacement for 9540) has 12.4X24 fronts and 18.4X30 rears on cast centers. So did the 9540HDC24 that I looked at but did not buy.

I believe that you are confusing standard tires with available tires. Either size is available.

Not confusing the issue just reading the manual. As for all free op manuals, there are things missing. After figuring out what the drive ratio is, I was able to clarify that the wheels on the tractor are of correct size and they have no impact on current issues
