What is the largest diameter tire size that can be fitted on the Cruze CTD?
Consider if you get a tune installed, such as a +40hp Fleece or Trifecta tune. The tune is interesting since the power comes in about 20% sooner in the rev range or about 20% stronger at the same revs compared to the standard tune. Could you get a larger diameter tire to give you a higher effective final drive ratio?
For instance could you go from 215/55r17 to a 225/65r18 this would give you an engine speed difference of 8.5%, right?
Even though the car is riding slightly higher dropping the revs by this much should give even better fuel economy.
Sure you would not as fast accelerate from stop, and you would likely force the car to down shift more compared to the smaller tire.
So what is the largest tire you can fit in the space given?
