BMX - Different size tires?

Large front, small rear?

Why is is done (for what reason)?

Why is it done in a manner different than on a motorcycle (large rear, small front)?

When did it start?

why is that pictue in your post...?

This was done way before I started BMX, so it's and old trick. Since there is more weight on the rear tire, you only need a skinny tire to get enough traction without causing undue friction that you would have with a wider tire (rolls easier). The wider tire is put on the front because it will put more tread on the ground and effectively give you better handling through the loose stuff.

:edit: The reason you have a wider tire on motorcycles is because there is way more power going to the rear wheel of a motorcycle than a bicycle, so you need more area to grip whatever surface you are on.

I have a better question: Why is it NOT in yours? :)

I don't know how to do it like that...

skinny rear tires are better for manuals

It was to generate enough interest for someone to answer the questions. Without the pic, the thread was getting views, but no answers. With the pic, the questions got answered.

.....Dirt tire generally in the front...(and there bigger)

Street, or smaller treaded tire in back for street grippin...


I dont know...!?








But what i do know is that i like that picture...!

You are a genius! Maybe they should try this technique at school... :beer:

that would be cool, if my bio teacher put pics of hot chicks in the backrounds of her powerpoints to make everyone awake...!
genius!

Generic insults are awsome.

confused.

haha

Thanks.

:beer:

yeah.

I think you'd see a lot more 4.0's than usual...

Yes, you're probably right.

Larger tyre = more grip where it counts, if your front wheel goes and you're not getting it back.
Motorbikes front tyres are dictated by braking forces and handling, if you look at motorbikes with less power the rear will be narrower because a skinnier tyre actually handles better, something that chopper builders should take notice of.

I'm thinking about a 2.25 front. I have a 2.0 there now.

Haro Joe Dirt of course (f'n' awesome all-around tire).

In '86 I bought (and still have) a Cannondale SM 700 MTN bike. It has a 26" front wheel & a 24" rear wheel. Very similar to off road motorcyles, especially trials bikes. This made it much easier to ride off of picnic tables and land rear wheel first. Also, smaller wheel, shorter spokes=stronger wheel. I finally replaced the rim in '98. As my Cannonball was only the 3rd year they made MTN bikes, I would hazard to say the mid 80's. Just a guess.

You realize that we're referring to tire width, right?

Maybe not....

I do on 26 inch wheel, works better and faster.
I never run same tread or size front to rear.
Usually I have 2.3 front -low psi\big tread and 2.1 rear -less tread\higher psi.

Why would be a paragraph or 2.
Try it?

WHY?:(

Because every post and every image on bikeforums.net should be in reasonably good taste, and appropriate for the very broad audience of the site. This is one of those issues that has to be dealt with evenly across the forums, so your image was deleted. In other threads, things quickly go bad when those kinds of images get posted.

More importantly, why bring it up a month-and-a-half after the last reply?

But what about members only here to be an ass?

That would be a separate issue, best addressed in a PM.
