Ignore the old fashioned inch or 700c markings. Look for three digit and two digit numbers with a dash between them and that's the ISO/ETRTO size which is the most reliable way of matching. You can vary the two digit width a little usually if you want (wider is smoother but too wide might foul your guards or frame) but not the three digit diameter.
Just managed to make out they are 700 x 23c.
Just arranged to buy a pair of vittoria zaffiro at 700 x 28c. Any body got knowledge of them?
My bike shed disagrees with you. The road bike is currently 28-630 (which used to be pretty common, along with 32-630) and I've also road tyres in 590 and 622 diameters, including a hybrid on 37-622s. Check, don't assume.All road tyres will be 700c which is the diameter of the the rim. The width of the tyre will be 23, 25, 28 up to a wide tyres for hybreds and tourers which can go up to 32.
They seemed OK but the ones in our shed cut up easily and have been replaced by Vittoria Rubinos.Just arranged to buy a pair of vittoria zaffiro at 700 x 28c. Any body got knowledge of them?
Not the best tyre, the Rubino is superior and only a quid or two moreJust managed to make out they are 700 x 23c.

How modern a bike has these size tyres on? I doubt whether a modern road bike will have any other size on other than a 700c. My Galaxy from 1974 has 27 inch wheels which would be would 630 but are not normally sold by any mainstream bike shop these days. The Op was for a modern giant bike.
