need some opinions

right now i am running 18s with 14/40 gearing. i only ride trails and have the mods in my sig. i have 21s laying around and was wondering if i should run the 21s with my gearing for my type of riding. or leave it be

I ran 20's all the time and just went to I think 22's, I really haven't noticed a difference except ground clearance I too have 14/40. I do like the better ground clearance.

you will have more topend with 21's than with the 18's. personally i think 20's would be good with that setup.

21" tires offer more ground clearance therefore are the better trail choice. The acceleration loss is something you won't notice on the trails. On a road, it probably gives you like 5mph more in top speed from 18" tires, but you won't get to that speed on trails.
