Hi all, 1st post here. I bought a 2018 3 Hatch GT and wanted Nokian WR G4 all weather tires, the dealer installed 225/45 18s as that is the closest size to the oem 215/45 18.
Normal from of traffic NH to Boston, CT, LI etc 70-80 plus at times. The speedo is now 2 mph slower then I am actually traveling and that will lead to a ticket, especially at this speeds.
And I live in a small rural town that has town 30 mph wide speed limit 1-2 mph error may not sound like much, but it is enough to get pulled over. In other towns its a ticket.
I cannot find anyone who sell a speedometer calibrator to simply adjust the tire height to correct the error for the 2018.
I have used Hypertech to do this on my 1998 Blazer for 20years ( I bought it new). The Hypertech Speedometer calibrator does not work on a 2018 Mazda
They sell a performance programmer, but it does not have a feature to adjust for tire height. And I do not need extra HP or Torque and have to run premium fuel.
What seems odd is that they add extra power but not the option to adjust for tires to handle it.
Any know of a company that sells a speedometer calibrator the works with the 2018 Mazdas?
I used the free app "Speedometer" on my Iphone to check before and after the tires were installed to see the difference.
Also Mazda does not offer any calibration through the dealers.
Thanks Wayne
