I moved up from 31" tires to 33" tires and my truck shifted at 41mph into overdrive but then when i go the bigger tires it shifts at 46mph now. I changed the tire size to 2654mm if i'm remembering correctly to put in what the new tire size is. Is it normal for it to shift later?

Larger tires MAY hurt your gas mileage, since your engine actually has to work harder just to maintain a set speed. And, your acceleration will suffer too, since the larger tires reduce the effective gearing. But, you gain ground clearance and you probably like the look better, so that's what really matters. - Jack |

as long as you have the right tire size and gear ratio your speedometer on the gryphon will read accurate, the mechanical dash speedo will almost always be slightly high but the odometer will be correct.
