Tires
Make sure you use a tire size calculator to make sure that you have the correct size once you go wider. And for the fear of potholes, please don't go superlowprofile.
Most of the online tire vendors have some sort of data about what size tire you choose and its recommended rim width its supposed to go on. The other thing is the bigger rim you get the lower profile you'll need to keep your speedometer somewhat accurate. There are calculators for that as well.
