Speedometer Question

[theslawdawg]

Hello Everyone,

Here is my question for the day. It appears my speedometer is way off. I normally don't drive 85 down the highway and get passed by every vehicle. At first, I thought it was the small tires that were on it when I first purchased the vehicle. However, after replacing my tires to a reasonable size (275/60/15) I noticed the speed is still way off. At low speeds, say 35 mph, it is accurate. Just not at the higher speeds (past 55mph). Can someone please tell me how to correct or calibrate? Thanks in advance.
