I'm running 265/70/17 and was originally on 265/75/16, never had running and I don't think my speedometer is significantly off.

ok so to be safe and have a correct speedo I should stick to 255/70R16 then?

With the sizes you mentioned, with the bigger tires, when your speedometer is showing 70mph, you'd actually be traveling 74mph

yea ill stick with 255/70R16 then speedo is still correct with this size

[dsr611]

If you want the larger tires, you can have the speedometer calibrated for the different size tires

I went from your size to a 255/70R16 with no change. There will be no issues with that size. 265/70R16 is also an option
