20' SSR SP3 arrived. Need help with tire size plz
 

So after 4 long months of waiting, my SSR wheels arrived to the US. I'm picking them up tomorrow and still can't decide my tire size.
My specs are 20x10 +21 front and 20x11 +11 rear.
I think my front wheel fitment will be more aggressive than my rear. So to avoid rubbing I could stretch a 255/30/20 on the front (barely stretched).
For the rear I think I could get a meaty tire and not rub but I think it will look weird if the front tire is kinda stretched and the rear isnt.
What tire size will give me a similar stretch look on a 11 inch wide wheel?

What tire size do u guys recommend for my specs? Never had anything wider than a 9in wheel.
Thx for your time!
