Dear Robert,
I was thinking about doing some light off-roading in my 2018 Nissan Frontier. My friend said slightly deflating the tires would help: is this true and, if so, what PSI should they be?
Thanks,
Toby
Hi, Toby!
Hitting some tough trails is a fantastic pastime and the 2018 Nissan Frontier is a great truck to get you started. In this instance, your friend is right: lowering your PSI will aid you when off-roading.
If you’re driving over loose sand, rocks, or mud you want as much of the tire’s surface area to touch the ground as possible. So lowering your PSI will actually give your Frontier more traction.
You’ll also notice that the ride will feel less stiff as you drive over obstacles, thus making life easier for everyone in the cabin. Although letting some air out of your tires won’t make them impenetrable, they will be more resistant to punctures.
Finding the right pressure for your Frontier will take some trial and error. Most stock tires are rated at around 35 PSI +/-: 15-20 PSI is a good starting point for off-roading.
Don’t deflate your rubber too much as this could cause it to come off the wheel.
Thanks for the question, Toby. Contact Kirkland Nissan, Washington if you need anything else.
