Yes, the F34 is equipped with a larger overall wheel diameter than the F30/F32.

If you're getting 20" wheels, a 30-series tire sounds too small - check the overall diameter yourself (as I don't know how wide the tire is).

Usually, they say to keep front & back wheel diameters within 1% of each other, and try to keep the wheels within 3% of factory specs.
