So I want to know about tire width.

I see a few fat tires out there now that look interesting and I`m just wondering about what is the advantage/disadvantage of wider tires.

And will I feel a big difference going from a 1.95 to a 2.35?

the smaller the tires the less rolling resistance and the faster they should roll. anything over 1.95 is really big. You will notice a big difference, I went from a GLH to a Dirthpath on the front of my bike and it felt like a chopper. The only advantage to bigger tires really are if you're either bigger, or you do huge drops and you want more cushion. Otherwise stick with 1.85 or 1.95 if you want a relatively fast rolling, harder tire.

that answer is completly different to my opinion, i didnt notice much difference going from a 1.95 to a 2.25 and it doesnt seem overly big. anything over 2.2 and you notice a little difference but not too much. i prefer fatter tires myself

The major difference is how it changes the steering angle.

2.25", surely.

big front small back, nuff said.

Sorry about that! Yeah 2.25 Maxxis Holly Roller or the IRC equivalent are what I`m seeing around the most.

I live in a metric world so I get confused trying to talk in Inches

Can anyone tell me more about what goes on there?

Will a fatter tire make the turning circle proportionatly bigger? OR perhaps smaller?

It dosent even change.

Actually it does change. By running a 1.85 back and a 2.25 in front you actually change the rake of the headtube because you push up the front of the bike by a quarter inch. This means that tricks like nose wheelies, hang fives, and other nose tricks will be harder. With a 1.95 in back its not QUITE as noticable, but it does make a difference. I can't stand huge tires, but that's probably because I ride my road bike a lot.

Thanks for answering for me. I'm glad someone else here "gets" geometry.

I Get that it changes. But if you buy a bike with a big front tire and get used to that right away it dosent even matter.

that isn't true though, you might not notice but it will effect the bikes geometry and how it handles. you just have to be more paticular about bike feel, i guess.
