New version of tyre is (much) smaller than outgoing model... am I within my rights to return them?

Next time buy 28's

All I wanted was something 2-3mm taller/wider.......

And you didn't get it, did you. Good advice from @potsy, but for next time.

You know how it works. If I order 28's they will actually measure 28mm and not fit my frame clearance. Then I will have to return them

TALC ??? Next you will be telling us you use hair products

If you get special pleasure from succeeding in an epic struggle to fit a tight tyre which is a 'mare to get on a rim, then do not use talc. And also expect to struggle by the roadside the first time it needs taking on and off.

To measure a tyre section, ETRTO has defined:

• The rim width on which each tyre section must be measured
• The pressure at which it must be measured, taking into account that the casing of a brand new tyre will stretch within the first 24 hours of inflation, so the measurement should be done after those 24 hours

For example, a tyre said to be a section of 23mm should be measured on a rim of 15mm internal width at 6 bars (87 PSI) after 24 hours.
A tyre said to be a section of 28mm should be measured on a rim of 17mm internal width at 6 bars (87 PSI) after 24 hours.

I have some 28's going free to a good home, and maybe a set of 26" mtb ones if jnr needs any?

All donations gratefully received, stuff Jnr, they might do for me. What are the 28s? Not some of those bloody awful Marathons I hope!

Some Continental wired ones that came with my single-speed, I'll have a sort out and see what I have going spare.

I have just seen the new Toblerone bar and I can't help thinking there is a connection between the new gaps between the pyramids and Skolly's tyres.

 

[ayceejay]

Sure enough the new gap is bigger
