Mongoose! Posted June 1, 2015 Share 25c tyres on a Giant TCR (2015 model)Have anybody maybe tried to fit a 25c tyres into a newer Giant TCR frame ?Front wheel will work, but my concern is the rear clearance between tyre and seat tube.A while back I tried to fit a 25c tyres on a “normal size (rim made for a 23c size tyre)– Ksyriums and the inflated rear did not fit into the frame – the 25c tire did not inflate wider but, made the profile deeper - as said the result was that the tire touched the inside of the seat tube.So what I actually want to know:Will a wider rim (22mm) with a 25c tyre fitted have the same effect? (wider AND deeper?) Or will it only be wider, with the same profile than a 23c tyre on a 19mm rim? (like the Ksyriums above )No luck with google and Unfortunately don’t know anybody (Bloemfontein) using 22mm rims with 25c tyres for a quick test on fitment. Thanks for reading and any advice will be highly appreciated. Link to comment Share on other sites More sharing options...
David Marshall Posted June 1, 2015 Share I've been riding 25mm tires for the past few years. Last year got a new Swift frame and had the same problem. Funny 'though I can still ride 25mm Gatorskins but the GP4000s touch. My son's Dedacci frame is the same. A wider rim will flatten the tire - a customer of mine has no problem with his 25mm rims fitted with 25mm tires. Looks like you are the one to test 22mm rims!

Hope this helps even though Its not the 2015 as you asking about. Link to comment Share on other sites More sharing options...

madbradd Posted February 23, 2016 Share Also wanting to run a wide tyre on a wide rim.... From David's post I reckon I'll be fine. Rims: 25mm external, 17.9mm internal (light bicycle 45mm U shaped).Tyres: Spez Turbo Pro 26mm (preferably) or 24mm. http://www.light-bicycle.com/light-bicycle/45mm-deep-carbon-700C-25mm-wide-road-rim-clincher-U-shape-tubeless-compatible-with-basalt-braking-surface/road-rim-clincher.jpg Link to comment Share on other sites More sharing options...
