They will do nothing to the speedo if he uses the correct size tire: 245/30-21 or 255/30-21
Front and 295/25-21 Rear.

The stock 7 series tires are: 245/35-21 and 285/30-21 which are about 4% larger than OEM 6er tires. Not a huge deal but your speedo will be off showing 4% slower than actual speed.

You will need 10mm front and 15mm rear spacers. 20mm will probably be OK with a more aggressive "pushed out" look.
