front tire sizing........?

[buster024]

i've got 20x11x9's in the rear, and I need opinions on front tire/rim sizing. I'm riding stock now. Should I jump to the 22's or 21's?
I ride mostly trails and backyard tabletop tracks.
Thanks!

stock tires r 22s. if u r running 20s out back then the best bet is to stay stock up front.

I have 20's front and back, i noticed a bit of difference while riding, the front sort of sits lower.

does it still ride the same with 20's in the front
