Hey everyone,
Ive googled this for a while and never came to a definite conclusion..
Is it legal to have 20" rims on a bf xr6? Id hate to have them and have an accident and not be covered by insurance.
Any help will be greatly appreciated

Yep, 19s are factory on the phoons so you can go up at least 2 inches in size? So 20s are a def yes

you can fit 20" on the BF but make sure you let your insurer know that you have gone to larger rims, as if you have an accident they might not cover you as the sizes are different.
