Going to start by saying sorry - this topic has no doubt already been done to death. The more I read the more confused I get.

I need a new set of tyres on my bike, something good in the wet & puncture resistant.

Bike (hybrid) used for the commute to work & about town. Currently the bike has 700*37 tyres on it. Label on rims says etrto 622*19-DIN Alloy C.

How low can I go 700 * ?

What difference will it make ?

Am I right in thinking I may need to change inner tube if I change tyres, depending on size. (going to change anyway - they have been repaired numerous times).

Any brand recommendations ?

Thanks - have a good bank hol.
