.....with the pr3's fitted the rear tyre was very tight to the rear hugger, Pr4's theres a good 3/4'' clearence, now why would that be on the same size tyre?
What appears to be different, overall diameter of inflated tyre on wheel, the width or both?

I can only echo what's been said about the PR4's. I changed after getting 3 screws in my BT23 rear one after the other. I've only done just over 200 miles on them but they are so confidence inspiring, it's like chalk & cheese. I wish my cornering skills matched the tyres capabilities!!!

How about more slack in the chain?

Yeh, I was thinking that at first, but doesn't a rearward axle movement of anything like 3/4" (19mm) to take up chain slack (for tyre outer surface to have moved by that much further away from the hugger) seem unlikely?  :084:  :027:

Sorry not had a chance to reply, the chain is fine etc, but the hugger with the previous tyre had around 3-4mm of clearance above the tyre, pr4 is a good 10-15mm no other changes just the tyre. I'm not complaining just a bit confused

Maybe the chain adjusters were wound back a bit (to take up excess chain slack) when the wheel with new tyre was re-installed. If so the axle (wheel centre) would be further back and the gap between tyre outer face and back edge of the hugger would increase.
Otherwise, have you checked the (cold) tyre inflation pressure?

Hi again for some reason i didnt get a notification that I had a reply, I have checked everything and it all seems to be ok, very strange. Just to add I rode in torrential rain on monday to work and these tyres are fab, very very surefooted in streaming wet roads. very happy with them  :001:

I'm planning to gt the PR4's on my next tire change. Just curious here about their grip on wet roads.

Succinct and to the point but I have to disagree - they are better than that.  :008:  They are the best wet weather tyre I have ever ridden - excellent in the dry as well.
