Trailblazer rim question

I have a question about the front rim size on a polaris trailblazer 330. I know that the rim size is 10×5 and is a 4/156 bolt pattern but what s the rim offset? I cant find this information anywhere. Also if anyone could tell me the rim offset for the back too as i am looking to buy aluminum rims for it. The tires i am looking at for the front are itp mudlights in 23×8-10 which is an inch wider do you think this will be a problem? Thanks in advance!
