Help re tyre width for V-sprint wheel

Hi,

Hoping someone can offer some tyre sizing help to a newbie...

I've just ordered this replacement rear wheel for my Analog NS:
http://v-sprint.com/product/track-wheels/custom-hand-built-track-wheels-quando/

My previous rear tyre which also needs replacing was a Resist Nomad 700c x 45c and I've been trying to work out what tyres I can get for the new v-sprint wheel.

I'm happy to go a bit thinner than 45c but have been struggling to work out what the maximum width I can use on the wheel is. It says 700c x 18c – 23c in the spec but does that mean I can use 18c to 23c tyres or do I use the 23c on the chart here http://www.sheldonbrown.com/tire-sizing.html which indicates I can use pretty much any width tyre up to 50c...

Huge thanks in advance!

Yes.

...or do I use the 23c on the chart here sheldonbrown.com/tire-sizing.­html which indicates I can use pretty much any width tyre up to 50c...

No.

The left hand column of the table is the width inside the rim. Or "Rim width (interior)" as it is titled.

Thanks so much Scilly, much appreciated.

One more question if you don't mind - would a 25 or 28 tyre be pushing it on those rims in your opinion?

Of course not, that's what it's all about.

You need to know how wide your rims are, to make an informed decision about which tyres to use.

So you either need to get your Google on or ask V-Sprint.

Sheldon's table lists what "works" (and he notes that he errs on the side of caution); the table attached was prepared by someone on here and details what's "ideal".

To answer your question (without knowing what your rims measure, but assuming they are at the narrow end of the scale), I'd say that 25mm will work reasonably well and that 28mm won't kill you (in the face with fire), but won't offer any advantage over a narrower tyre and likely handle worse.

23mm would be the "safe" choice.

25mm would be fine, 28mm will work but required a slightly higher than normal pressure to stop this squirming feel.

This is assuming that the V-Sprint rims have a normal 13-15mm internal width.

Got it. Think I'll go for a 25mm then.

Thank you both, very helpful indeed.
