The CForce 1000 comes with 27", 6 ply tires.

Who plans to plus size and why?

I am very tempted, because I would like another 1" of clearance.  I ride rocky mountain roads and I will never hit the mud bogs.

I am concerned for two primary reasons.

#1. Taller, higher center of gravity vehicle and don't want more pucker factor on off-camber.
#2. Bigger tires that could create more stress and problems with the clutch.

Has anyone gone to 29's and if so, what is your experience.
