250 Cup on run-flat tyres??

  1. My car has “Extra Load” run-flats on it; these were either fitted from new, or by the previous owner.


    Should it really have run-flats on??


    It’s got a space-saver wheel in the boot – I thought these were for cars that have ‘normal’ tyres on.
     
  2. Does "Extra Load" mean they're run-flats??
     
  3. No XL refers to the higher load rating. Run flats are pants in my experience and don't really have a place on a performance car.
     
  4. Thanks, was surprised it would have run-flats on, but that’s what the previous owner said and then when I Googled “Extra Load” it came up as reinforced or run-flats.


    Why does a relatively light car such as the Megane have reinforced tyres??


    Just out of interest, what tyres came as standard on your Cup-S and are you happy with them, or have you changed them to something different?
     
  5. Forget the XL bit. It's meaningless. Just refer to the load index (a 2-digit number, like 95 in this case) which relates to the max weight for that wheel. When 2 identical tyre size come in 2 different loads (91 and 95 for instance) the 95 is called XL to avoid confusions.
    In this instance it mainly means that the sidewall is stiffer which is the main reason for Renault picking it.
     
  6. My car came with PS2 which are fine for road use. I track my car monthly so I run Nankang NS2Rs 180 semi slicks. If not I would have picked Yokohama V105
     
  7. Thanks, much appreciated, it makes more sense now. And also explains why there is still a space-saver in the boot.
     
  8. Check the pressure in your space saver btw ! They normally are down to half after a few years lol.
     
  9. Thanks Nick
     
  10. then remove the space saver as the weight is equivalent to a mild engine remap
     
  11. Ha ha, yes I noticed!!! It could be argued as being ballast though!!
