Prior to fitting my IRC tyres on these HED Belgium Rims, I had Specialized Turbo Cottons fitted. They were the 24mm wide ones, but measured over 27mm on these rims. Conti GP 4000 SII in 25mm measure over 28mm on these rims from what I have read.

On my Bike (Giant TCR Composite 2), 28mm wide tyres are a really tight fit, so I prefer to use tyres that measure under 28mm wide when pumped up

My next set of tyres will be the IRC Roadlite Tubeless and from what I have read, they measure wider on these rims. So, I will be getting the 23mm wide, which should measure just over 25mm when fitted (the 25mm measure close to 28mm wide)
