Do bigger tires need less psi?
In an effort to explain optimal tire pressure in the simplest terms, think of it this way: the load of any vehicle is supported by the amount of air in the tires. Therefore, a larger tire needs less pressure than a smaller tire to carry the same vehicle weight.
What PSI should my 35 inch tires be?
Lower the pressure to about 25 psi, and see how it handles. For a 35″ tire, on a Wrangler, the pressure should be around 24 – 26.
What should the inflation pressure be for low profile tires?
Check the manufacturer’s recommended tire pressures to be certain. Also, for extremely low profile tires, there may be so much rim and so little tire that increased pressures could help. Because in a lower profile, wider tire/wheel combo, the tire is more spread out, laterally, it needs higher PSI to ensure even tread contact with the street.
Which is better lower or higher tire pressure?
Lower pressures will have a larger contact area on each tire. This means that they feel more sluggish on steering input. However, they will also have more grip (higher contact patch area = more grip). Higher pressures will also stiffen the sidewalls.
How can I improve the performance of my tires?
A more radical approach would be a switch to smaller-diameter wheels and higher-profile tires. If the consumer purchased a performance vehicle with 19- or 20-inch wheels, the car’s larger brake rotors may prevent the smaller-wheel route. Can we improve handling and ultimate grip by increasing tire pressure?
What happens when a tire is under inflated?
Under-inflated tires: Tires that are under-inflated will cause increased rolling resistance and will decrease your fuel economy. The outside edges of the tread will wear faster than the center and the tire can even be damaged due to the excessive heat created from under-inflation.
Why is proper tire pressure important with oversized tires?
Larger tires handle a vehicle’s weight differently than stock tires do on almost any vehicle. Once you install those 35s, 37s or even larger, the manufacturer’s tire pressure recommendations pretty much go out the window. So why is proper tire pressure important with larger tires?
Where is the inflation pressure on a tire?
Many people mistakenly think that the correct inflation pressure is located on the tire’s sidewall. What’s listed on the sidewall is the maximum inflation pressure for the tire, but keeping your tires at the maximum PSI could make them wear faster or compromise your traction or braking abilities;

Can you increase tire pressure to improve riding?
Modifying tire pressures from the vehicle manufacturer’s recommendations can improve ride and handling. However, unless you’re recommending a slight increase to account for weather and leakage, or you’re making suggestions for off-highway use, I suggest keeping those recommendations to yourself.
