Unless your stock tires were larger than 33", you've got it backwards. Use the link below to go check the ratios yourself. http://www.1010tires.com/TireSizeCal...?action=submit
If your stock tires were 26575/16 and you went to 305 70/16, then your off by 3.57%, so when your actually travelling at 60 mph, the speedo will read 57.8. The odometer should be impacted the same.

BigBoy's GPS is right on, I measured my stock rear tire 265/70R/17 at 40 psi and it reads to be 30 and a about a half inch diameter. The 10 % difference calculates right out using the ratio and proportion solution above with a 30 inch stock tire. So keep an eye on your speedo and reduce it by 10 % to avoid speeding tickets. Plus reducing by 10 % is easy to remember and you can figure that one in your head.
