Question about wheel size and tyres

javidr · September 4

Hi

question about wheels. I’m about to buy a wheel that says “25mm inner rim width (30mm outer)”

i am not clear if a 28mm tyre would fit there or the minimum is 30mm. Do any of you know if it would fit there?

thanks

etro publishes charts, the 2024 version is here...

...from this site...

for 25mm inner width, etro says 29mm minimum tyre size (used to be smaller)

since tubeless became popular, and manufacturers came up with different rim edge designs, road rims aren't as simple as they used to be
