Has anyone else been having this problem lately? We been setting the tire size to the customer supplied size and on 3 or 4 different occasions now it has been out by 5%. I dont have the trucks on hand so I couldnt confirm the actual size of the tire (I asked them to check, waiting to hear back).

One customer has his tire size set to 31.75" with a ppe yet we set it with the efilive calc and it was 31.7, so it all seems good, but yet they are saying it is now out by 5% and the tire size we supplied with that adjustment is 30.2". The rear differential is 3.73s and confirmed.

I find it just so odd that the PPE would be happy at that OD and efilive needs a different one. Not sure how that would even be possible, that said I have not confirmed this in person, only going off what I am being told.

Just curious if anyone else has seen this on their day to day work? Seems odd.
