Tyre help

[xxinsane09]

Hi, 2 part question,
I currently run 700 x 40c tyres on my hybrid, would I be able to run x42c and if so would I need to change the inner tube as well or will the current one fit fine?
What would be the max width I could run on the rims?
Thanks all

Tell us what bike it is and upload a picture of the rim ideally one where some markings are visible

The tubes will be fine as for tyres it's down to frame clearance.

The 42s will be about 2mm wider so if you currently have a few mm either side of the tyre at the fork (front) and chainstays/seatstays (rear) they'll be fine. No need to change the tube.
You can do the measurement and maths to determine how wide you can go.
