Guys forgive me if this has been said on here before or a known thing however I got my son a 2013 Maxima and it was all stock and a buddy was selling some wheels for a really good deal. Long story short I went from stock 18s to aftermarket 20s.. after having them installed and driving off the speedometer doesn’t work and the key light stays on as well as the Brake light. Is this normal behavior? I asked one of the guys at the tire place and he said some cars you have to get the comp reflashed. Can someone shed some light here so I don’t go down the wrong path and waste some money
