    As you know the green car from the tow lot that we got has been lifted 1.7 in or 40 mm so we fitted the new 215 65 15 tyres. While I was at it I had already ordered some of the cheap $24 supposedly made by Pacific tire sensors they arrived installed them in the wheels they look just like the factory except they don't have the green label and they don't have the little door on the back of them for the battery these are just open like a lot of the later models are. Installed all four of them . Logged them in tpms light off. The bigger tires raise the car up about another inch looks like I have about 6 in clearance under the car now easy to get in and out of that's for sure we'll see what happens to the gas mileage The tire seemingly are running me about 3 mi over the speed limit not too bad.

    Is this based on GPS, because my OEM 195/65r15, the speedometer was showing 2+mph faster than actual distance traveled - according to both my Garmin and Samsung Phone using google maps.

    Straight, flat highway or county road runs with unobstructed satellite signals will yield the best results. When you take turns or drive up and down rolling hills, it'll effect accuracy of distance travel and miles traveled, so that effects the GPS speedometer.

    Man I'm just trying to get an idea of how basically far I'm off there's a few places around here with radar set up that I go through so far it looks like I'm ahead 3 miles an hour That's average of all the nonsense and different speeds and that's just so far I'm not going to look into this but a little bit and then I'm done with that doesn't really matter I just don't want to be 7 to 10 off and if I am I want to know which way but so far everything seems pretty normal and nothing's really interesting other than the MDF is telling me that I can't get past 36 mi to the gallon so far but yet on this first tank of gas I'm approaching 250 270 on a half a tank which is about normal for what I do with this car it'll be 410 or 4:20 and I'll be down to one pip and the light might begin to flash and then I'll get to put about 9.4 gallons in the car typical for the three or four that I'm usually driving generation twos
