I just wanted to create a new thread so it's easily searchable in the future.
I put on a new set of 285/35/20 315/30/20 NT01's. I bought these because R888R's weren't available to me locally yet and I had to get a set of tires immediately.
I see a wheel speed differential of up to 4% faster in the rears at around 240kph. I don't think I'm losing traction at that speed so I'm assuming the differential is only due to the difference in tire size. No lights on the dash for wheel spin either.
Is 4% a lot?
