19s speedo problem??

[teegee]

im about to put 19s on my E36 with 235/35/19 tyres and was wondering for such big wheels for E36s does the speedo on the car change and will i need to adjust it? thanks!

those are taller than the stock diameter of 24.7 inches(627 mm) whereas yours are 25.5 inches or 647mm i believe. It will just raise your gearing and make your actual speed faster than your speedo i think.
