Yes tincaman. This is my bike.

What bought this on was my friend and I are about the same weight but different bikes and his bike just freewheels smoother than mine. I think i will just change the tyres to begin with. That seems the logical thing to do.
I don't want to get to obsessed with components. I realise it's more important to just ride. I'm 57. I don't need to race, just need to ride and enjoy

No. Still a newbie and learning as I go along.

Did you buy online or from a shop? If the latter, take it back and get them to check, easy for them to do

I agree with everyone else. Change the tyres before you consider the wheels.
@vickster had a pair of 28c Vittoria Rubino Pro's up for sale for a very reasonable price, but sadly for you I got there first
They're an excellent mid-range tyre, though, with pretty low rolling resistance and robust p*nct*r* proofing, so excellent for everyday use. Go seek them out.

Haha. Thankyou very much.
Right. Forget wheels, tyre homework here we come.

Depending on tyre pressures, 25s should roll better, but the ride could be harder (all assuming the rims will take 25s). Try a premium 25mm tyre like a Continental GP4000 and see how they feel. Keep the 28s for the winter

Good site this:

I found out why my B'Twin went so sluggish after I put the Shimano R501's on, it was because I'd bought Vredstien Fortezzas to go on them. Silly me.

Perhaps just have a closer look at the wheels first. Take them off and spin them holding the axles. They should spin quietly and smoothly, if not take them to your LBS and see what they recommend. Are the discs true? Also spin the wheels on the bike to feel if the pads are binding, if they are adjust them, it's very simple and there some videos on YouTube to help.
Your rims wil take 25c tyres but will make very little difference, the pressures will however. If you can rule out everything else then by all means try a different tyre.

Its generally the thinking now, that unless you race, a 28mm tyre rolls better (less rolling resistance) than a 25/23. The lower pressure you run at also makes it more comfy, and you have slightly more grip. You still need to choose a good tyre though to get these benefits, as tyre compound and carcass rigidity will negate all this if you choose a nasty tyre. You can't go wrong if you can afford the GP4000s

I have to confess, I don't understand that.
Why would a 28c tyre, of a given brand, offer less rolling resistance than a 23c version of the same tyre at the same pressure? I would have thought the narrow tyre would produce less resistance due to it having less surface area in contact with the road, and therefore less friction?
No doubt a clever person will be along in a second with all kinds of complex mathematical formulae to explain this
