Thin 700c tyres
Hi all

Hope you guys can help, I'm confused about tyre sizes! I've just bought an old Viscount bike, something to lock up outside London bridge station without it being stolen! Looking at the tyres on the bike they are cracking and need replacing.

The existing tyres are really narrow and on the side 700x18 is printed. My problem is I can't find a tyre that narrow, most of them being 700x23. Does anyone know a tyre that would fit my skinny wheels.

Thanks very much!
if you can find the 700x23 they will be fine. 23s are plenty skinny enough for commuting those are to skinny also. can you measure your rim width and get back so we can recommend a wider tire for you that would fit

Thanks for getting back to me, the rim width internal is 13mm, external 19mm.

can yo post a pic of your tire and brake caliper so as to see what type reach you have as tire clearance must be taken into account.What are the names on the wheels and exactly what model and make and if possible the year of bike. your rims are about as narrow as they come but you may be able to go with a 25 or 28 safely without fenders of course and you will have more meat and hopefully less chance for flats and rim damage from city commuting. one more consideration is are they clincher rims with tubes

Hi, the rims are made by Alesa (913-822799), not sure about the age but I'd imagine they're at least 15 years old. I'm not using mudguards, and I'd definitely prefer less chance of punctures!
roll with 700c X 28 , good all arounder and decent meat and try to find one with a built in tread guard and use a quality tube
an example here
32 would be alright and these are priced good
I would not go bigger than 32
I did not look to see if your Bio stated where you are from so there you go

Thank you, I really appreciate your help... I live in the UK but have found somewhere that sells that brand over here.

Thanks again.
Another good tyre is the Conti GP 4 season. It is fast, slightly wider than the road racing one and all of the GPs are constantly being tested as some of the best stuff to put onto your bike (a good compromise that is still very fast and also quite sturdy).
I have the GP4000s on my road bike, at most one or two flat tyres in the whole time (and I used to commute a lot).
