Road Cycling - What tires with wheels

I'm sorry in advance if this has been asked before, I did a search and couldn't find anything. I have 700x25 wheels and was wondering if I can put thinner tires on itor do I have to change the wheels aswell. I would think the tire has to be the same width as the wheel but just in case I thought I would ask :(
Sorry if its a stupid question :sleep:

Probably not.
My old road bike has Mavic rims and came with 700x23 tires.
The bike is now my commuter (and occasional road bike) and I put 700x25 tires on it for commuting.

I would see no reason why 23mm tires wouldnt work on them. It's only 2 mm. The tire should be able to expand enough to cover that. Try and find a friend that has 23's and see if they fit your wheels okay. It only takes 5 minutes to see.

Can I ask,,,, why do you want to change to thinner tires?

You should have plenty of latitude there. Unless it's a wide touring rim, you can probably run 20's on them, but 23's should be no problem at all. I've installed 28mm tires on 19mm Mavic rims...no problem.

George!

Thanks guys :D.
I see alot of riders using thinner tires and kinda understand that a thinner tire will give a better performance (speed & handeling) am I wrong :confused:

I understand that thinner tires may have a higher rolling resistance as they will have to deform more to achieve the same footprint area (provided it is inflated to the same pressure). A thinner tire will have less aerodynamic drag.

Wider tires will have better traction, because of the contact area. Thinner tires will have slightly less resistance, and better turn-in characteristics when cornering. We are only talking about 2mm though. I seriously doubt that you'd notice any difference in the two.
