edit: just read the full thread, glad you're all sorted.
Hi Monksie. 🙂
So it was rubbing because there wasn’t clearance for 25mm in the rear?
Yes
From what I've read, GP5000s come pretty true to size, unlike GP4000S IIs... So look out for a good deal on at least one 23mm GP5000.

Hi James 😀
Have I bought rubbish tyres?
crikey! glad you got an answer even if not a full resolution monksie!
Phew! I was about to offer you the loan of a spare set of wheels to see if that helped.
Gatorskins? Old school puncture-resistant winter commuting tyres in a slippy in the cold and wet sort of way. I use GP4000s all year round here and they're lovely and grippy and as we don't have sharp flint and similar debris on the road, they don't seem to puncture any more than anything else.
I've never really got the trad winter roadie thing where you ride nice grippy tyres when the roads are dry and grippy and swap to something with half the grip as soon as it's cold and wet when, arguably, you benefit more from grippy rubber. Then again I mostly ride my cross bike on the road in winter, so what do I know?
Thank you for the offers and potential offers of wheels to try. I’m going to have to put up with the tyres I’ve bought until the summer. I’ll kid myself that they’re good for resistance training without wearing a further hole in my frame.
Well I'm glad we got to the bottom of that anyway.
If you're after something marginally narrower, I have some spesh s-works turbo 24mm which are very lightly used.
Drop me a line if they might be of interest for cheap-ish?
Yay
You can carry a pump and tube now to avoid the walk ( and train ride) of shame
Glad you got to the bottom of it
BTW what frame has tight tolerances that a 25 will rub to cause braking effect?
Well OP, I'm glad you know what the problem is but I was kind of hoping that we'd find out that your bike was haunted by the ghost of one of your old bikes.
Ha! It’s a BMC Street Machine or something similar sounding.
To be fair, The Hutchinson Intense tyres are very wide for a 25c.
The Prime wheels are probably 25mm or 27.5mm wide at the rim bed if they are relatively new so the tyres will probable run much wider than the 25mm written on the side of them. The bike might be a bit older and not designed for the newish trend in wheel width.
