Anyone running wider tyres on road rims? Rigida DP18s should use 18 to 25 tyres for the width of rim, but have read and heard that people do run slightly wider tyres with no problems.

Anyone doing this? Any pitfalls / advice?

Looking to put a 700c 28 on A rigida DP18 instead of a 23 or 25.

I would be alright.
I run 25 tyres on DP18, originally intended for 18-23 tyres.
No problem at all!

28s seem to be fine, slight risk of the beading slipping off the rim if you put hard sideways force on the wheel at lower (~75psi) pressures though (resulting in a burst inner tube usually).

Rigida site specifies 18-25 for DP18s

They're 13mm interior width

Table at Sheldon Brown also says 18-25 for 13mm interior rims.

Also states "Many cyclists exceed the recommended widths with no problem"

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
