Kinda-sorta.
The tire pressure will influence the actual diameter of the tire, and for a given engine rpm/gear, a bigger wheel will give greater speed, and a smaller wheel will give lesser speed.
A wheel with higher pressure will also roll easier than a less inflated Wheel. This means there will be a tiny bit of power available to make the car go faster if the tire pressure is higher.
In reality, this is all fairly unimportant outside a race course. Excess pressure will caue the tire to wear faster, and unevenly. The ride will be bouncier and handling poorer. And unless your engine is powerful enough, you won't get any use of the bigger diameter either. It'll just rev a little lower, giving you the same, or less top speed.
No but, tire size does effect wheel speed sensors.
Absolutely, and if one tire is more flat, thus wider, it will or could cause a spin out and loss of control. It is directly related to the square root of the tire pressure. According to testing cited by the NTSB (National Transportation Safety Board) the speed at which a normal tire will begin to hydroplane is 10.35 x the square root of the tire pressure. So, if the recommended tire pressure for your vehicle is 36psi, the speed at which you can expect to hydroplane would be 62 mph. Let that tire pressure go down to 25psi and you're hydroplaning speed drops down to 52mph!
i can effect the pressure and make gripping difficult
Speed affects the frequency and pressure affects the wavelength.
Actually, if you check your tire pressure regularly, you'll find that the pressure only changes by +/- 2 PSI as a result of normal driving. This will not affect tire balance. However, if you experience more severe pressure changes (10 PSI or more), this changes the shape of the tire slightly and alters the cetrifugal force. This can have a pretty dramatic effect on the balance since the centrifugal force is proportional to the square of the rotational speed. When you have your tires balanced, the pressure should be set to the nominal pressure recommended for your vehicle (may be different for front and rear) before you balance the tires.
The bigger affect on wind speed is air pressure.
Only when the weight the tire is carrying changes after the tire's pressure has been set. For example, if a large truck suddenly dumps the load it is carrying the tire pressure will decrease. Small weigh differences (like between one human and another) should have very little effect on the tire pressure.
What year 2007 has a rpm type when a tire gets low on air wheel speed sensor sends signal to computer low tire pressure.
cause.
Low tire pressure or failed tire pressure sensor.Low tire pressure or failed tire pressure sensor.
Water, speed, tire pressure, weak struts, driver...
Yes, definitely. Lower tire pressure increases rolling resistance and hinders fuel economy. Deflate your bike tire by a fair percentage say 50 and drive around, it isn't easy.
