Plug in your tire size specs below and it'll tell you what you can expect. You can have your truck's tire size updated in it's computer (with a 'good' scan tool or the dealer), so the odometer will read correctly. You can do it yourself with AlfaOBD software (do a search on this forum).
Tire size comparison the easy way. Use our tire size comparison calculator to compare diameter, width, sidewall, circumference and revolutions per mile.

Thank you. I have the Diablo so I should be able to correct the speedo.
One other issue I thought of;
Will different size front vs rear tires cause any errors in the computer?
I'm debating running wider rear vs narrower fronts and trying to match diameter is difficult.
Yes truck is 2WD. I'm basically wondering if speed sensors are just side to side or if they are also front to back, possibly affecting ABS, or anti-spin.
That calculator says that the tires are a 6.5% (Wild one was corrrect!) difference, so at a speedo reading of 60mph, my actual speed will be 56. I can correct that, and I was more concerned about RPM, but it shouldn't be much of an issue.
Thanks again.
