I currently have 26 act stock tires. I really want the 27 inch bighorns. I do not want to add a lift because I don’t want to increase my Center of gravity on hills too much. I heard the bighorns run big and can be actually larger than 27in.

Should i just get the 26 inch bighorns or do you think i can fit 27s without a clearance issue and effecting its performance on inclines? I dont ride mud and mostly ride hard pack trails and rocky hilly terrain.
