2.35 in front and 2.1 rear?

[johnandjerri]

Can someone explain to me the reason. I see alot of people doing it but I don't get it. Thanks.

Lighter back tire...

Bigger front for more control, smaller rear for better rolling resistance and pedaling.

I went up to 2.35 in front to improve traction. Then, since I had added weight, I went down to 2.1 in rear to compensate.

I am using a 2.5 in front and 2.35 in back, both Nevegal stick-E. My bike came with Specialized Resolution Pros, 2.35 F and R, and those tired SUCKED. I am a BIG fan of the Nevegals, but that's just me.

I like the 2.5 in front to help me with the skinny ruts/channels that would sometimes make me eat crap OTB. The weight doesn't bug me much at all.

You got it right "Bigger front for more control, smaller rear for better rolling resistance", I also find the smaller tire works well for going through rock gardens, let the rear tire do the tracking and manual the front tire.

Generally for an AM bike you want a larger tire in the front for traction, control, and taking hits. The rear tire is skinner to increase acceleration and speed. Depending on what you want to do with the bike XC, AM, DH will partially determine your size setup and type of tire.

Personal preference also plays a percentage in your decision. Every rider is different. Some like high slip angles and others don't. Some will give up traction for more speed. Keep in mind you can't have both high traction and speed. One has to give.

As Dino, Coleko, Lee, and many others have mentioned to me, experimenting with tires is the cheapest thing you can do to your bike. For example. I felt my Maxxis High Rollers were really heavy so I switched to XC based tires. WTB Mutanos in the front and IRC Mythos in the rear. What happened? It rolls pretty quickly, it's light weight, but traction sucks for me. I plan to swap my High Roller back on the front to regain control and experiment with a different rear tire such as the Maxxis Ignitor. Try it!

I'm a Cross Mountain rider....climbing up and decending fast (a hero in my own mind) on my Ellsworth Moment (6 inch bike). I run with a 2.3 front and 2.1 rear to give me lower rolling resistance climbing and much more control coming down.

Rear Tire is a cross country tire (Maxxis CrossMark) 2.1
Front Tire is a Specialized Enduro 2.3..this tire blows up front so don't get it.

I'll be purchasing an s-Works Eskar 2.3 front tire soon

Hope this info helps

During the winter, I am using a Maxxis Mobster 2.5 inch in the front and 2.35 in the back.

I run a 2.35 fr and 2.1 rr on all my bikes, regardless of which type/brand of tire I'm running. All the reasons already listed above are spot on.

Try it and I'm pretty sure you'll be happy and won't go back.

Not just too be different, on my SS I run 2.35 rear and 2.1 front. The 2.35 rear is so I don't spin out climbing steep hills.

I'm not sure that it's the exact dimensions (2.35 & 2.1) that are the selling point.

On my 26" bike I have a 2.2 Velociraptor up front & a 2.0 Serfas Gator in the rear. Same concept as many have already mentioned, with different dimensions. If I weren't so in love with the 2.0 Gator, I would not be opposed to a larger rear tire, either. Many riders claim that weight is their main factor in the size of the rear, provided that you get *enough* grip and braking control.

I currently run 2.1 Ignitors on both ends of my 29er, but am in the market for a bigger front (Why the hell does Serfas only make a 2.1 29er tire?? I love their tires; great tread, amazing wear & bullet-proof flat protection). As I mentioned before, I would not be opposed to bigger tires in the rear, there's simply not a lot of clearance on my Unit 2-9.

I'd say it's more about having the best traction available up front, which you get with a bigger tire. Your front tire is more apt to wash out from under you on fast corners, especially when braking is involved.

For the rear, you want good grip while pedaling & good braking. In this sense, the size of tire is not really *as* important since the rear wheel will always be going in the same direction as the bike (in theory, at least!).

It all depends on your riding style and how much of a factor weight plays in your choice of tire.

I run a WTB Mutanoraptor 2.4 up front because it helps my Titus Racer-X absorb some of the bigger hits and tracks really well through sand/rocks/ruts. I run it soft at about 28 psi.

In the back I often run a 2.1 Exiwolf to lighten up thew rear end and still provide incredible climbing traction. Run it with more pumped than the front because it carries more of my weight.

I like the 2.1 kenda small block rear 2.35 kenda nevegal stick e front in the summer 2.1 kenda nevegal stick e rear 2.35 kenda nevegal front in the winter

[chongoblanco]

I'ts an old bmx & cross country trick helps out alot with accleration, plus {the back of the bike will follow the front} t.k blazer

[richie_rich]

Want less rolling resistance? I run a Maxxis Oriflamme on the rear and for traction at the front a CrossMark. If you haven't tried the Oriflamme you should. It's weird I know, but it does hook up really well...unless it's wet and you're screwed.

Running Continental Vert Pro UST in front and WTB UST 2.1 in back and works well for me!

Eskars are here and will be tested soon
