What size tires did you use? I have 26's but the overall diameter is close to stock so no speedo adjustment was needed. It can be adjusted with a Predator tuner, of the dealer can do it to, but it's not the rim size, it's the tire size that is important.How do I adjust the speedometer on my 2011 Platinum to read correctly after going from the stock 22's to 26 inch rims? Thanks
If the overall diameter is bigger wont that equate to less milage?How off is your speedo?
Tirerack says 305/30/26 is the correct size, but with that size tire the speedo will be 3.4% off.
Tire Size Sidewall Radius Diameter Circumference Revs/Mile Difference
285/45-22 5.0in 16.0in 32.1in 100.8in 628 0.0%
305/30-26 3.6in 16.6in 33.2in 104.3in 607 3.4%
Your car will also have more miles on it then it really shows on the mileage gauge.
