Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Switching tire without changing tubes?

My old tire is fine but I want to replace it with slicks. Everywhere I search, people mention replacing tubes with replacing tires. Is this necessary if I have not suffered a flat?

In a word, no. It is not necessary to change the tube.

I've worked for shops where it was policy to replace the tube when doing a quick tire change for a customer, but that was only to stop people from claiming the tube was fine before we changed the tire. Some people were pumping up their tires(with slow leaks) and scamming the shop for a free tube.

If your tube holds air, there's no reason to replace a perfectly good tube.

Tubes have a life independent of the tyre they live in.

if the new tires are significantly smaller than the old tires then you may need new smaller tubes as well

Never heard such nonsense in 30+ years of riding. Equipment paranoia seems to keep rising.

this may help explain why my LBS had a bin with "free tubes" sign on it. i pulled out a couple and fully expected to have to find and fix holes. not a bit. tubes were perfectly good. and more unusual is that they had a lot of new tubes for sale too.

good of them, i guess.

And vica-versa.

When I put new tires on 84 team fuji and 85 club fuji last year, I re-used the old tubes (under original tires) more from curiosity than cheapness. A year and hundreds of miles later per bike the 80s tubes are still going strong with no flats.

If the tube is good, continue to use it.

Yea, I just assumed that since the OP was going with slicks they would be smaller.

Expect some non-sense from a person with less than 1- year of riding.

I use tubes until they either have patches on the patches or the valve fails.

No real need to. But generally, at least for me, the valves have a limited life span and if you have 50-100 rides on the tube (with the same number of top-offs before heading out) it might be worthwhile to replace it while you have the tire off. But it's certainly not necessary.

If you change a tire and neglect to change the tube, you will die.

It doesn't help that Continental includes instructions with its tires that recommend replacing the tube when replacing the tire. (Yeah, I did read the instruction sheet once. I may be the only person who has ever done so.) I guess they're not content to have sold someone a tire, they want a few more bucks too.

"Everywhere I search, people mention replacing tubes with replacing tires."

You prefer to believe what a few posters will say over "everywhere" else? ;-)
