Hiya BC instead of going up from 23's to 25's why dont you try coming down from 17 to 16 stone
Then you'll be the same weight as me
I've sent my Schwalbe Ultremo's back after my tyre fail, the nice kind man there is replacing them free of charge but I did run 600 miles on them without a single puncture at max pressure, it was only when the weather got damp that I suffered my first one then another then another
I found them to be a good tyre and will certainly be putting them back on in the summer, I bought myself a pair of Michelin Krylion Carbon tyres for now which I done 65 miles on Sunday club run with no probs and have bought some Gatorskins for when it gets really wet
By the way i've reduced the pressures i use now as someone suggested I may be running too high, I went with 110psi rear and 100psi front and it was a nicer ride, all I have to do now is deflate my missus slightly
