A common question within the GTR community is what Tyre sizes should I be running on my car. Getting the correct rolling Radius is very important on the Nissan GTR for a number of reason but most importantly is the strain that is put on the 4WD clutch system when the rolling radius isn't correct but there are also other elements that are impacted to such as
- Vehicle Performance
- Fuel Efficiency
- Safety
- Traction Control and ABS
- Odometer and Speedometer Accuracy
- Suspension Dynamics
