After comparing with Paul's CR on OE tyres & the difference in ride quality is significant.
Is it the original or Mk2 runner? Could be difference in Tyre pressure as well. Remember the original runner had lower tyre pressure ( 33/36 ) although most changed to the standard 36/42 after testing as the lower pressure was a bit wallowy.
Sometime when I get mine back from service the pressures have been set to original pressure. The first time this happened I wondered what had happened, until I checked the pressures

I'm running Angel GT's ( 36/42 ) and from what I remember they are similar to PR3's and the Scorpions.
Very happy with the Angel's and will be fitting the same again.
