Tire pressure settings for daily driving

physics · 12-04-2018, 09:05 PM

I have the sport model with the 19" Rays forged aluminum wheels and shod with Bridgestone Potenza S-007 245 on the front and 275 in the rear. The dealer sold the car to me with 28 psi in all tires, which I promptly pumped up to Nissan's recommended 32 psi. The maximum recommended inflation pressure on the sidewall is 51 psi, so I split the difference and now am running 40 psi in all tires. The ride is not noticeably harsher but it does seem to be a little more precise and responsive in the feel. I'm going to get a tire tread depth gauge and monitor the wear across the tread. My goal will be to equalize the tread wear across the tire.
