I always thought that the PSI normal pressures for
Cupra 19inches should be in the high 30s, like 38 or something PSI. And yes, the car is still new, it takes a bit of time to losen up, assuming you are giving it either Shell Vpower 99 / Esso 97 or Tesco Momentum 99 to drink? Please don't say 'oh the reuglar Premium 95 RON. From the factory, tyre pressures are super high from my experience, usually like 5 PSI too high! I do have the pressure handheld meter, so I just release until it settles to the desired PSI. After it passes 2k miles, you can look to get (now this is from experience) around 5mpg more like for like, which
Cupra wise, would be high 20s, low 30s, which is what most are getting. On a run, maybe even high 30s, or low 40s (if 50mph for long stretches).
