I’m actually considering switching to 35 mm Continental Terra Competition Race tyres.
They only weigh around 350 g and on my 32 mm internal width rims they should probably end up around 40 mm wide once mounted.
The only thing I’m unsure about is whether that’s already a bit too stretched on such a wide rim.
Tagoola states for the XPLR R32-50 rims:
“compatible with 700x36C–64C tires”
Also, there is a user here on the forum already running 36 mm Challenge Strada Bianca tyres on a similar internal width without any problems.
What do you guys think? Would 35 mm still be perfectly fine on a 32 mm internal rim, or already a bit too extreme?
