How 265/70R17 Tires Affect Speedometer and MPG

Installing 265/70R17 tires will usually make your speedometer read a little slow, because the tire’s larger 31.6-inch diameter changes the distance traveled per revolution. That tire diameter creates speedometer inaccuracies of about 3-4%, so when you see 65 mph, you’re actually moving near 68 mph; at 75 mph, you may be closer to 79 mph. You should recalibrate if you want exact readings.

The larger tire diameter also changes your final drive ratio. At highway speed, your engine turns fewer RPM, which can feel calmer but also reduces leverage off the line. Without re-gearing, you may notice sluggish acceleration and weaker low-end torque on grades or during quick starts. Expect a modest hit to fuel economy, usually 2-3 mpg, because the larger rotating mass demands more energy to spin and stop. If you value precision and control, factor these changes into your setup before you drive free and fast. Additionally, using low rolling resistance tires can help mitigate some of the fuel economy loss associated with larger tire sizes.
