New tyres for my Sirrus Pro

I just bought a second hand 2012 Sirrus Pro hybrid, delighted with the bike 
However the factory tyres were replaced with some nasty no brand Chinese ones (32 front, 28 back :? )
The rims are still original. I think the factory tyres were Espoir Sport, not sure of the width.
I road cycle to improve my fitness and cover from 30-40 miles per trip and not more than 1500 miles per year.
Average speed I did on my old mbt with Continental Sport Contacts 26 x 1.3 was about 16mph.
First question I have is what width tyre should I get 25, 28 or wider?
I presume all these will fit on original Sirrus rims?
As the roads I train on are not in best shape.
I am on a budget of £40 and considering the following tyres :
Michelin Lithion 2 700x25 (light, durable, good protection, popular, cheap and great reviews, not made wider than 25 I think)
Continental Gator Skin 700x25 (also light and durable but twice the price of the Lithion2, is it worth it?)
Any other suggestions, advice or comment are most welcome!

Michelin Pro 4 endurance ?

The Michelins are too dear for me.
I think I'll get the Espoir Sport in 28c.
What's the deal with folding vs non folding versions?
Folding tyres have a bead made of kevlar fibres rather than steel wire. They're a bit lighter, and if you're of a mind to you can fold them up. There's also a slightly different technique to mounting the two types time because a folding tyre's a lot floppier than a tyre with a wire bead, but it's not a big deal.

You can get a pair of 28mm Conti Ultra Sport folding tyres for £27 from Wiggle

No idea which to choose and I've not ridden either.
Michelin Pro4 Endurance at only just over budget - £44 for the pair: http://www.probikekit.co.uk/bicycle-tyr ... 90762.html
Budget of 60 quid and a slimmer 25 tyre for best speed, lowest rolling resistance but still durable with high puncture resistance. Ridden on dry roads only.
Thanks !
Specialized Turbo - the S-Works version are fantastic, huge grip and low rolling resistance. And I've read great things about the new Michelin Power range. Can you stretch your budget by £2? Michelin Power Offer

The 25s should be ok ok my rims right?
I think I just need longer valves due to wider profile.
You need longer valves to fit through deep section rims, it's not related to how wide the rim is. You may want to get new tubes though, ones that have been inside a 32 section tyre may be too fat to fit in a 25.
