New tyre, front or back?

I had to get a new tyre for my road bike. Should I put it on the front or the back?

Is this a joke? You put the new tire on the same wheel that had the bad tire that needed replacing.

what he means is that he is going to replace the bad tire but is wondering if the new tire should be in the front or the back, like the gooder tire should be in front or back.

Yes that is correct. Is there any advantage to putting it on the front or the back. Sorry thought this question was clear as to what it would mean because clearly you would replace the tyre that was no good.

Tire rotation seems to be a risky proposition. I replace a worn or damage tired as it becomes worn or damaged without rotating the the other into its place. IMO tire rotation is for cars, not bikes.

I always put the new tire in front... It's better to have a rear tire come out from under you around a corner than a front..

New tire goes on front, since it's less likely to flat and has fresh rubber that will grip the road better.
Old tire goes on the rear, since it's more likely to flat and a rear flat is a lot easier to control than a front flat.

There's no need to rotate tires for the sake of rotating, but it makes sense to put old front tire on the rear when the rear has worn out. It's not a complicated job and doesn't take much time to do.

Normally you can go through 2~3 rear tires before a front is worn out, so why would you want to use a half worn front tire and a fresh rear tire?

For safety, you always want to make sure that your front tire is worthy. However, if your front tire is used but still has good skin on it, leave it.

The rear wheel gets a LOT more wear than the front. Assuming that the older tire still has good skin, I would put the older tire on front and the new tire on the rear. Rear tires wear out at least two or three times faster than front tires.

Unless the front is obviously worn out I'd just leave it, otherwise I replace both. It's just a regular part of upkeep to replace tires before they are so worn that I get flats.

I put the new one on the front and move the older one to the rear. I don't want the most worn tire on the front for safety reasons.

I typically put the new one on the front and swap the front to the rear. I just recently got a big gash in my rear and just replaced the rear, since my front's only been on for a couple of months, however.

The answer to your question is very logical. To stay upright you have to steer therefore the better or new tire goes on the front.

Rear. The rear tire carries more weight and wears faster, so you want the most tread back there.

Only if wear is your biggest concern, if you like your bike to handle well, than you want tread in the front. A worn out tire in the rear can give you more flats, or impede optimum acceleration. A worn out tire in the front can cause all sorts of dangerous and unpleasant situations if it washes out from underneath you.

You assume that tread on a bicycle tire makes a difference in cornering. According to Sheldon that isn't true. I'm open to the question though.; your reasoning is the same I apply to car tires.

Sheldon Brown says no. http://www.sheldonbrown.com/tire-rotation.html
It is common for a front tire to outlast a rear tire by as much as three to one. Rear tires have more weight on them, and also have to deal with drive forces.

This disparity in tread life is exacerbated in the case cyclists who rely on their rear brake (you shouldn't! See my article on Braking and Turning.)

Well-meaning cyclists, even some mechanics who don't know any better, sometimes try to deal with this by swapping tires, putting the less worn front tire on the back wheel, and moving the worn-but-usable rear tire to the front. The idea is to equalize the wear on the two tires, but this is a serious mistake, don't do it!

The only time tire rotation is appropriate on a bicycle is when you are replacing the rear tire. If you feel like taking the trouble, and use the same type of tire front and rear, you should move the front tire to the rear wheel, and install the new tire in front.

The reason for this is that the front tire is much more critical for safety than the rear, so you should have the more reliable tire on the front.

If you have a blowout, if it is on the rear tire, you have a very good chance of bringing the bike to a controlled stop. If your front tire blows, you can lose steering control, and a crash is a real possibility.

tread only matters over loose terrain.

you want your front tire to grip the loose surface or cut through the slop and you want your rear to bite into the loose surface.

That makes sense, since bike tires don't have a whole lot of tread anyway. Glad other people chimed in.

It is always better to have the new tire in front. 'Cause if the front tire slips, 99%, you kiss the tarmac (or the ground,whatever you please...).
If the rear tire slips instead, it's piece of cake to oversteer a bit, and bring it back where it should be.
Hope it's understood.

Again the assumption that a newer tire has more traction. I just don't believe it.

And if that's not true, then it's down to chance of failure and wear, which have contradictory dictates.

Depends on how old the old one is. Old rubber develops a slick crust, so cornering grip will be reduced at extreme lean angles.

If you leave the front tire on the front, it'll likely get sliced to useslessness before much of the tread is used up, on the roads I ride on, anyways.

On my last rear tire replacement, I just replaced the rear, cuz the front was only a couple months old and I felt certain I'd wear out this rear and the front will still have plenty of live in it.

You can straight swap all the time if you want to also, DMF. Sheldon won't rise from the dead and smack you upside the head.

Well that's what I usually do - a straight swap.

My tires never get old enough to get crusty. And yours shouldn't either.


Sometimes I get this feeling that my mother is going to rise from the dead and smack me upside the head. Is that what they call 'guilt'?
