    We are changing out tires on tractors from low profile to 11R22.5. They are 07 volvo with an eaton 10 speed and D12 engine. Anyone know what value to put in for the pulses per mile to make the speedo correct? Thanks

    I believe 497 is the number you are looking for

    Actually I set it up in VCADS. with Ratio of 3.58, 16 tooth output wheel, 501 RPM of tire(497 was very close it just varies a little from one tire manufacture to another thanks though)...the number needed to install was 28697 pulses per mile.
