Different Wheel Diameter Front And Rear

[Chunners]

I'm running 255/40R17 on the front of my R32 GTR and am looking at putting 275/40R17 MT drag radials on the rear. There's about a 16mm (2.5%) overall difference in the toatal wheel diameter. Will this will cause a problem with the ATTESA system? Does anyone know what the maxium difference in diameter you can have between the front and rear before it becomes a problem?

Thanks,

yes it will cause a problem.

yes it will cause a problem.

I'm already running 265/40R17 on the rear which makes a difference of 8mm and i've had no problems. What is the limit before it causes problems?

Thanks,

you might not find an answer to your question because its something that no one really does

i think you'd be safe to assume that the bigger the difference in overall diameter, the bigger the problem it will create.

its probably also a problem that may take a little bit of time to appear, like running 2 different tyre sizes on the rear of a rwd car. it will eventually wear the diff out.
