I am currently using Goodyear NCT5 for my Gen2.
My dad's Nissan Slyphy using Continental Comfort Contact 1.

My dad gonna sell his car off in November, and wanted to buy the pickup or SUV to run some business.

I would like to ask, should I swap the tires? Swapping tires is costing me some money under 100 bux. Is it worthy?
I feel like CC1 is pretty quiet. But not sure if it is the car's good riding quality or the tires did help.
However my NCT5 is fair in every aspect but quite noisy when cruising at 90-110.

Wild guessing only. Haha.. Because I will be doing balancing also since I went and swap tires ad..
28 bux for 2 tires balancing in workshop nearby my place..
Then 4 will be 56 bux.. Including some charges for tires swapping.. I assume around 80 bux..
