Advice on demo machine

I picked up the mower today during the monsoons we've been having down here in Louisiana. Got it washed up and put away in its' new home. Can't wait to take a few spins around the yard on it but looks like I'll have to wait until the ark hits land...

Is it possible/adviseable to put wider tires on this thing? I know that if I can and do, I'll need to get wheel spacers or offset rims.

Your thoughts?

You can and should if mowing angles. Just make sure you purchase tires that are flat not rounded. Picture for understanding. Wider rims are necessary to keep the most contact with the ground.
