    2.5 vs 2.7 tire sizes

    I have ridden several 2.5 tires ad I like the maxxis minions the best but my question is what size is best?

    i have a 2.7 up front and a 2.5 in the back. i bought the bike used and thats how it came set up. I rode my dads bike (2.5 front and rear) at northstar one time and wasn't as comfortable turning on it, but im not sure its due to tire size... but it could.

    If you're riding downhill (I doubt you'd be riding XC with those tires), 2.7 does make a big difference. I ride the same as moosey with 2.7 in front and 2.5 in back, and I swear those 2.7 minions have a gravitational attraction to the trail. But that's only if you value grip more than RR. They do roll slow but I don't pedal much so I don't mind. Find out what you feel most comfortable with!

    it is awesome to roll the 2.7's and get a lot of grip.,....I LOVE THE 2.7 michelins....but I am now rolling the 2.4 Big Betty. I have shaved 3 pounds...think about that and also the bike accelerates faster....start trying to use smaller tires and lean the bike more

    wow you can feel the gravitational pull. actually i sometimes ride a 2.7 in the rear and a 2.5 up front. i get to run low pressure and have better grip both in braking and cornering. i cant feel the gravitational pull. depends on corse. but i never ride a larger front than rear. imho i dont think you ever need to run a 2.7 front unless wet. there is no gain to run such a large front under dry condtions, its in your head. but you will see a difference doing it the other way around.

    i remember when people ran 3' nokian tires up front with there zzyzx or hanebrink forks that made no sense. have you ever tried running it the other way around. just give it a try

    try riding half day with a 2.7 rear and then switch to a 2.5 and see if you feel a difference in the braking power, grip and impact on hits. then try the same for the front another day, you wont feel squat. i dont care that thats been the way for years but with the way corse are built today, this is the future. no doubt its got a slower roll but not by much, you gain more in late braking and faster cornering. most of your weight is in the rear rolling through a burm in fact you front hardly touches the ground. other than off camber or big boulders. please enlighten me to why you run a larger front in today types of corses except for the fact that its old school thinking.

    As to which tire size is best? It really comes down to terrain and personal preference...

    Also, the older maxis casings run small (minions, highrollers etc), so their 2.7 is like most peoples 2.5's.

    Basically narrow tires can dig deeper into loose/muddy material to find traction on the bottom, wide tires tend to float over soft/loose material due to lower contact pressure.

    A narrow tire digging deep, has to displace a lot of material = more rolling resistance in loose terrain.
    wide foot print tire floats over the top, so while it has more friction deforming the tire, this is far out weighed by not having to displace loose material.

    Narrow tires that sink into loose material also tend to rail road, ie that in a rut feeling, where as a wide tire with float doesn't do that.

    On hard pack a narrow tire has lower rolling resistance.

    So yeah, preference... I prefer a wider tire, running RQ 2.4 front and back, not the ridiculous 3.0 gazas from back in the day, they have a place, and its on bikes that ride in snow lol.

    from what i have heard and seen the minions tend to run small but that doesnt worry me so much. I think i will go with the 2.5 does anyone have compound suggestions im thinking a single ply exo 60a in the rear and a stickier dual ply exo 42a in the front?

    60a is the harder compound and does last longer. I have never ridden the 42a, but I'm assuming because its a softer rubber its grippier but doesn't last as long. I know that maxxis does make a 3C tire where the center of the tire is a 60a to give it longer life, and the edges are softer rubbers to give it grip. I've had one for a while and I like it, but its all about what floats your boat.

    I rode a DHR 2.5 super-tacky for about six weeks last fall, 1-2 days on the weekend only. It was new at the start and shot at the end. Didn't mind as I got it on sale for <20 bones. Worked great, just not a tire for someone looking for a reasonable amount of mileage.

    Well, let me go get my reading glasses and some fiber but here is my reasoning...
    If you are going hard into a turn (non-bermed) I'd rather have my rear tire break loose first. If the front breaks loose before the rear you go DOWN.

    well maybe you need to practice more. please dont tell me that you think the .2" wider rear difference is gonna make your front wheel scrub or better yet not allow your back to break loose when you need it to. i'm not trying to be mean, it's just that you dont know what your talking about, especially cause you havent even tried it.

    oh god another one. your the guy who crosses the street as soon as someone takes a step forward. please let me know whats wrong with it, really. its like the guy who makes remarks about bikes they havent tried.

    dirt bikes have wider rears, i know its to help accelerate but doesnt cause the front to was and allows for late braking, same with street bikes the rear is wider and it doesnt offset the cornering. your braking is used hardest in the rear although most of the braking power is up front. you go through more rear tires than you do fronts.

    I measured mine. from edge to edge of opposing knobies, it was 2.4x", so true to size. It definately looks bigger, but that's because the casings for Schwalbe's are HUGE.

    Obviously you've never participated in your own test. it makes a difference

    I run a 1.50 street tire on the front and a Surly Endomorph 3.7 on the rear cause I like the chopper look.
