23c front 25c on the back????
Got a nasty gash on my rear Conti. 4000 today 700 x 23c . I have the same tire's on another wheel set but they are 25c .Can I run a 23 on the front and a 25 on the back? Is this a problem?
Thanks
Thanks

I'm not aware of any frames or brakes that can't handle a 25, but you might have one. Other than that, I don't see what problem it could cause unless you're really anal about your exact speed and distance and forget to change the wheel size on any cycle computer you might have.

no problem, except that if you weigh more than about 150, they're BOTH too small. But mixing sizes won't hurt anything.

That statement COULD be valid if we’re talking about touring bikes, however we aren’t. Running a 25 in the rear and 23 in the front will make no difference to anything but your computer if you have one on your bike. Carry on, all will be fine.

No problem. That's what my dad did for a long time. He even argued that it was better for rolling resistance since the rear tire (which carries more weight than the front) didn't get misshaped as badly.

I weigh 210 and just yesterday I replaced my 700X25 tires with 700x23 (got a better deal on the 23s). I didn't really notice much of a difference and will probably stick with the 23s since I can find better deals on them.
I don't think you will have any problem mixing tire sizes.

Last year I switched from 23s to 25s on both front and rear. While the ride quality has improved noticeably, there has been no perceived difference in rolling resistance. Don't cheat yourself out of increased flat resistance by staying with a 23 in the front.

Sure, you probably can mix them to no ill effect. But it's like mixing tires on cars...under severe braking or handling conditions, you may have a difference in road friction between the tires which could result in the front or rear sliding out at a greater rate than the other tire, resulting in subsequent unpleasantness.
I've locked 'em up and slid them out enough times that I would not mix tires myself.

The only reason I wouldn't do it permanently is having to buy different size tires. Since you're going to be replacing the rear more frequently than the front, keeping the right size in stock is a PITA. Use up the 25s, then just go with one size, buy a bunch when they're on sale, and call it good.

Go ahead. If you weight more than say 180 it's probably a good idea....and even if not, it's fine.

Put the other 25 on the front, just to make my OCD side feel better.Everything must be equal and uniform,I must count now 1,2,3...1,2,3...1,2,3

But (seriously) I've had that happen on several occasions, and I don't know if I would have been able to stay upright if I'd been sliding at different speeds front/back.
The Attack/Force are probably the same rubber compound, which makes the coefficient of friction likely to be pretty much the same, even with slightly different diameters.
If you're changing 1) diameter, 2) tread pattern AND 3) tire compound, it's more likely that you're going to get differential grab.

I still think that you want to have the same rubber compound in both tires though, which is something that would be difficult to control other than the Attack/Force combo.
But you do make a good point.
