Hi all, I've always sort of thought that my speedo reads high, I have not verified with a gps or anything but I drove thru one of those "your speed is **" flashy thingy signs and it read 3-4 mph slow compared to what the car was saying, at highway (65mph posted) speeds, I have to drive at 75-80 to keep up with traffic and at an idicated 45, I know the car isn't going 45, just wondering if anyone has noticed this. Oh, it is a base N.

I've not noticed any inaccuracy but I suppose if they somehow used the same speedometer calibration the smaller tires on the base would read higher.

I switched to 18"'s for winter and it didn't throw off the speedo by the amount OP is discussing. Its common for the speedo on a car to read a little fast for liability reasons, but we are talking a couple of miles, not 35.

(the reasoning is simple, a car company can be sued if you get tickets or accidents because the speedo says 40 when you are are going 50, but they won't if the speedo says 50 when you are going 45)

I think he's just off 3-4 mph at an indicated 60, probably just the liability thing you mentioned.

The base has 225/40-18, not sure what size winters you are using but even still this should only change it by 1 mph or so at 60.

I'm going to verify it on a gps next time I drive it, I'll update the post asap.

Edit: Okay I took my GPS with me and it looks to be off a tad less than 3 mph, so not too bad, I guess everyone is just driving faster nowadays and the car makes you feel like you're driving slower than you actually are. I have a Jetta that registers low about the same amount.

My N with PP is actually one of my most accurate vehicles compared to GPS on my phone and radar detector.

The Uniden R3 and Waze/Gmaps read within 1mph of each other and usually match.

I find my Kia Sedona is about 2mph off while my wife's Corolla was 3-4mph off. Nerve racking to do an indicated 83mph to make GPS read 79mph.

I find the N is within 1mph most times and occasionally 2mph of GPS indications. I'm curious how the wife's new Mazda CX-5 reads.

I live in Huntsville al . Here if you drive 70 on the highway you get passed by just about everyone , occasionally i try to keep up with traffic and wind up at 80-85 . I have passed a couple of those "your speed is " signs and i am always a mile slower that what the sign says. I noticed when i bring up the digital speed indicator the speedo is always 1 mile faster then the digital.
