With regards to wheels, I don't really want to swap out new wheels and tires, especially since I'm still on the sbp. But maybe I'll look around for some tires I can mount on there. However, I don't know how wide my wheels are (I'm thinking 4.5-5.5") and a 225 might be too wide for them.
I'm not necessarily on a strict/tight budget. I would just like to upgrade that part once and not have to worry about it or feel like I should upgrade it again for a long while.
