Wider tires on a 01 Blazer....

Picked up an 01 a few weeks ago, and wanna go a little wider on the tires. The 235's are only 9.5 inches on tread width.
Any suggestions? Do I have to get 15x8 rims to go to a 10.50 on tires?

Also want to do a suspension lift. Any one else have one they'd recommend?
