Checked your pressures? Too high and you would significantly reduce the tyre contact patch
Have checked them a couple of times - I’ve got TPM on the Boxster and they’re all showing as 33, which is the recommended pressure.



Unless you plan on white lettering them? 
thought I'd totalled my alloy but just got left with a bulge on the tyre
