Black 10

My buddy is looking to add the 2006 FX4 20inch wheels on to his 05 XLT since he found a set mounted and balanced for cheap. He has stock 17's and the new wheels will be around .8 inches taller all around which I think should only throw off the speedo to a point where if he is really going 65 it will read 66.7 ish. Anyone see any problems with this or should I suggest he alsso get a tuner to properly calibrate. He is obviously looking to bolt right on for the cheap route.

Thanks Bob R
