Recommend me some tyres!

[Marcellus]

After many thousand of miles i'm looking to replace my road tyres.

I've had Vredestein Fortezza Tricomp tyres on which have lasted well but wondered what people recommend.

Now for a real numpty question, what size are they??

It looks as though 23-622 (700x23c) is printed on them but too worn to tell, the rims are Mavic Ksyrium SSC SL so any ideas?

Ok next numpy question; 23 or 25 what's the difference?

I've tended to run my 23s at 130psi in the dry dropping to 110 if i go out in the wet.

I'm struggling to find Vredestein Fortezza Tricomp in 25s can only find them in 23s.

As that's what I've been used I think I may go that route again unless anyone can give me a good reason not too!
