Hey Em! Panaracer makes a 2.3 in their Fire XC Pro. Some of my friends run them up front.but I think they are mainly for traction in loose dry conditions. There can be a real clearance issue if you get mud in the treads!

Hey I have been able to ride a bit w/o my back hurting too bad, so I guess I'm getting better. It's been almost a year since my car accident! I should be good for spring riding.
