woah thats kinda confusin for a 33 id be stickin with 18s personally.
fronts you'd be going 22 or 35 depding what look and how you want it to sit how much work to make it fit etc.
rears 9.5 +0? or 10.5+22 will need lot of work for 10.5s and lots of camber so without knowing your application im given you advice on what i would do.
for practicality (and not knowing what rim it is or desing) you could easily do an 8.5 or 9 front with a 9.5 rear but will be pretty conservative with the high offset options.
