    Front and rear tire sizing

    Noob question here...


    I've seen some people ride with a wider rear than front, and vice-versa. What are the advantages of running with a wider rear and the other way around?

    Traction, and better cornering.
    I've done the 2.35 rear and 2.5 front. It was OK, but I ended up liking the 2.5 f/r better.
    I guess I like the cushion of a 2.5 tire.

    wider the tire, the more grip is available.
    skinnier tire provides low rolling resistance.

    you want grip in front, and low rolling resistance rear. never really want it the other way around.

    .
    skinner also helps going from one edge to the other quicker in corners

    This season at N* i ran full 2.3 DH bead Specialized Clutch. I believe they are 40a/42a compound. I really liked them and plan to get more next season. but some of the people who rode the same thing or 2.3 chunders said that they wish they had bigger tires at least for the front especially in a place like mamoth.

    you do get more pinch flats in back ,so a wider tire in back would protect the rim a bit more.

    a thinner tire will get less pinch flats than a fat one in the rear, but ya you'll ding your rim more. Also, smaller rear tire drops your ride height and slackens the bike a bit
