Relationship between Wheels and Tyres???

This is a subject I struggle to understand at all and if anyone has time to explain a little, I would appreciate it greatly.

I think the 37/35/23 etc refers to the tyres thickness and 700 or 622 to the tyres volume but I cannot relate these to rims and what tyres go on which rims

I have been commuting on a hybrid for three months and doing 40+ mile rides at the weekend and I am ready for a road bike. I am thinking of buying a cyclocross bike as it looks like great fun and I think the more durable frame would be better for me as I weigh 96kg.

I am looking at the focus mares which come equipped with 622 * 35 tyres. so my questions are

1 - is it feasible to have a second pair of wheels set up with road race tyres and matching cassette so I can hot swap the wheels depending on activity

2 - could i run cyclocross and road tyres on the same wheels, it would be much slower to change but cheaper.

Any insights greatly appreciated

    You shouldn't have any problem putting some thinner road tyres 23/25*700 on the Mare's standard wheels.

    The difference between the various tyre measurements is described here -

    In answer to question 1, there is the issues of cassette and chain wear. Chains and cassettes wear together and if you put a new chain on an oldish/old cassette you'll normally find a fair bit of jumping around and it won't be much fun.

    in all honesty you should have a cassette and a chain for each wheel, or just move cassette from one wheel to the other, leaving the chain on the bike (this is what I do). Not hard if you buy the tools!

    I know this is an old posting, but did you get the Mares Cross in the end ?

    I'm looking at doing the same thing with road tyres alternating with the cross ones, and want the roadies to be thin.

    If you did get one and swap the wheels/ tyres then let me know.
