Tyre/Rim question?

Seaneh

Right lads, my current tyres are big chunchy Releigh 700 x 35c touring tyres and while insanely puncture resistant and very reliable, they are slow as hell.

I was wondering, what is likely to be the lowest size I could drop to?

Would 25c be too small for the rim?

Depends on the width of the rim.

Page 7 of this document has a table which should give you an idea.

Any info on the rim itself? I know my road wheels are marked 13x622, so 25c would be the max for them, according to the table.

The rim has no indiactors on it, just a logo MNU or MNV cycles or something, no sizes etc.

from the diagram on pg. 7 of that doc, i could just pull the tyre off and meassure across with a ruler and find out, yeah?

Looks like it, from the inner edges. I suppose you'd need to be fairly precise, ther's not much difference between 17 or 19mm:)

Presumably the 35c tyres are what came with the bike? I'd guess that manufacturers would go somewhere in the middle of the range, ie not stick 35s on a 21mm rim, so you're rims might well be 17mm or 19mm.

Yeah, the 35's came with the bike.

Really hoping it's a 17mm so I can drop down to 25c, gives me a lot more options tyre wise too.

I went with 32mm marathon supremes on my hybrid, which are semi-slick, very puncture resistant and much lighter than the 37mm marathons that came with the bike. The 28mm Durano plus could also be a good option, I use the 25mm on the road bike and find them good.
