The MY PUP has a staggered wheel config, 255/35R21 front, and 275/35R21 rears. Looking at winter tire options and I decided to go with a set of four 19 inch x 8.5 wheels and 255/45R19 tires and no longer stagger.
According to tiresize.com the 19 inch config is an identical match to the PUP fronts - 28 inch diameter and 720 rev per mile - but when compared to the rears on the PUP the 19 inch config will be different - the rear on the PUP is 28.6 and 706 rev per mile. So now the question is what effect, if any, will this have on my sensed speed and distance.
If there is a change by changing to 19, I am looking at displayed 60 MPH is actually 58.7 MPH, so I will travel less than reported by the odometer. The MY has a wheel configuration option for 19/20/21 inch which I assume is only for range estimates, have not seen anything about speedometer changes.
My questions, for anybody who has already figured this out or know:
1) How is the speed measured on the MY, and will the 19 config on a PUP result in a change in reported speed and miles traveled?
2) If there is a change, do I submit a service request for a speedo re-cal and then again next spring when I switch back to the staggered config? Or do I just live with it? I might just sell the 21 Ubers and buy another set of wheels if this gets too complicated.
TIA...![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
