Is 28 bad for tires?
No, a tire pressure of 28 psi is generally lower than what’s recommended for most cars, which is typically around 30-35 psi. Running your tires at 28 psi can cause poor handling, increased wear on the tire edges, and reduced fuel efficiency. Based on normal tire sizes for each segment, small-sized car are usually 30 psi, medium-sized cars are 36 psi, and large cars are 42 psi. Keep in mind that warm tires normally exceed recommended cold tire pressures by 4-6 psi.
What size tire is best for gas mileage?
As mentioned above, wider tires usually increase fuel consumption. So, what about narrower tires? Narrower tires have a smaller contact patch, leading to less friction and lower rolling resistance with the road. The slimmer shape and less weight also help reduce wind resistance while driving. Rolling Resistance: Narrower tires (like 28c) can have lower rolling resistance on smooth surfaces like a well-paved road. This means they require less effort to maintain a given speed. In comparison, wider tires (like 32c) may have slightly higher rolling resistance due to their larger contact patch with the ground.Aerodynamic drag in testing: 28mm tyres were ~1w faster than 30mm at 45km/h. W more drag than 25mm. But that drag penalty disappeared on rough roads, where wider tyres rolled faster and more efficiently.
Can I go from 55 to 60 tires?
It’s highly recommended to use the exact tire size recommended for your car. However, in a pinch the tire width and aspect ratio can be changed slightly and still fit on your rim. Although this will still work, keep in mind it may have adverse effects on the performance of your car. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle.
