correcting the speedo after changing wheel/tire sizes

Hey everyone,

I wanted to see what everyone else did to correct the speedo after changing the wheels/tires on their m. I switched up to a 19 inch setup and according to what i found after cruising speeds around 65 I should be about 4 mph off or so.

Wasnt sure if there was a different way other than getting a tune or something along those lines

Thanks!

Hi there, 19 inches are the normal setup with our cars.
When I had my 22's this was a whole different story though.
My car spit an CEL and referred to a malfunction regarding my speedsensor.
I really never did anything else, then getting my code erased by the dealership till the day, I sold them and got myself 19" OEMs.

my car came with 219m's so they were an 18 inch setup :/

It's not really a big deal to me but i figured if there was an easy option to correct it then I might as well do it

Mine came with the PP so I had upfront the 19 inches and my winter DD's are the 18 inches that came along with your car.
I never really feel the need for a speedo calibration when swapping my wheels for summer or vice versa.
Aint getting it, sorry...

Sometimes I wish I could see what the people that worry about stuff like this look like lol..
Seriously, its not that serious, who cares if your speedometer is off by 0.3 mls per hr? It would be illegal to have aftermarket wheels if it mattered that much.

I'm sorry that I like to be meticulous about it, the original post said 4 mph. Is it a big deal no, but like i said if there's an easy option to fixing it then I'm all ears.

Thank you for your input

Sadly i have not heard of any fixes. This bothers me slightly too as i often times go with a larger than OEM sizing tire/wheel for summer and then a smaller size for winter. The difference is negligible, but would be nice if there is a quick fix/calibration.

Hopefully someone knows ;D cheers.

4MPH off? What width and profile tire are you running currently vs. your old setup?

stock 219m so 265/40/18? and I switched over to a 285/35/19. This was from a calculator online, but the gps in my radar was reading about the same off as well.

Who knows, not a big deal

easy fix would be to drop down to a 285/30/19 to get you nearer to that OEM height and mitigating some of that speedometer inaccuracy. Other than that, I don't think there's any other way to fix it.

All M3 speedometers read fast. E46M3 had the same thing.

I too wish there was an easy way to correct this as with my slightly smaller rear tire diameter setup (275/35/18's out back and 265/35/18's up front), the miles are piling on the odometer faster than they should. I use the speed feature on Waze when I'm on a road trip to keep my speeds where I want them vs. what the speedometer reads, but it's an extra hassle that I'd also like to fix.
