Replacing old 27 x 1.25 Tires (lemmy.world)

Howdy, I recently gave some new life to an old 1980s raleigh road bike that I found on craigslist turned into a commuter. The tires are somewhat old, and I'm looking into replacing them. Would you recommend any different sizes for the wheels? Brands to look for? It's not a common size tire on modern bikes. Also, I currently have 700 x 35c inner tubes in the tires. Is that an issue or will they work just fine for now? They were provided to me by my local bike shop.

The tube are good. If you wanted new wheels you'd need to check clearance with 700c wheels and make sure your brakes reach. I have schwalbe marathons on my 27"wheel bike and love them.

Thanks! I'm hesitant to replace the wheels because I have an internal hub on the rear and replacing the wheels would mean paying for a rebuild. But based on doing some more googling it looks like that would be my only realistic option down the road.

Edit: I just wanna say y'all are so lovely and helpful here.

I wouldn't (and didn't) switch my 27s out and have had no problems. Wait until your hubs need servicing and then revisit and see if there is anything a new wheel size would help you with.

Second this on the brake clearance checking. I had an old west German steel road bike with 27 x 1 1/4" wheels and thought I could just swap in modern 700c road bike wheels and be happy. However the brake calipers on the bike wouldn't work as the rims were now in a slightly different location and wouldn't adjust far enough to reach. That said you can get extenders and longer reach brake calipers if you're fully committed to putting a modern wheelset on, but worth checking everything will work/fit before going too far down that route.
