The 2009 Acura TSX is offered with only one engine, which Edmunds says is a “2.4-liter inline-4 capable of 201 hp and 170 lb-ft of torque.” Comments on the engine range from “sufficient if not overabundant” power from Car and Driver to “surprisingly good low- and mid-range punch” from ConsumerGuide.
Why do race cars have wide tires?
racing tires tend to be soft because that generates more friction. Unfortunately soft materials have weak shear strenth, so a large area is needed to support large tangential forces. (In effect, the amount of force that friction can exert is limited by the shear strength of the materials.)
What tire width is best for snow?
A narrower tire does a better job in snow. As a rule of thumb, for winter tires you can reduce the width 10mm, increase the aspect ratio 10 percentage points, and get a wheel one inch smaller — in this case 215/60R16. This is called Minus One sizing.
Are wider tires better in rain?
Wet condition driving — Wide tires are better for driving in wet weather since they have sipes, which help to trap and remove water from the contact surface. Narrow tires have sipes as well, but since they have a smaller surface area, they have less of them.
What’s the difference between 245 75R16 and 265 75R16?
As you can see the first digit of one tire is 245 and the other one is 265. It means, the width of the tire 245 75R16 is 245 millimeters and the tire 265 75R16 is 265 millimeters. So the difference in their widths is 265 – 245 = 20 millimeters.
Why do cars shake at high speed?
As you get into the higher speeds, if you distinctly feel vibrating coming from the engine, this could be a result of a lack of power, fuel, or oxygen getting to it. The spark plugs, fuel filter, and air filter should all be checked and replaced as needed.
What happens if one tire is bigger than the rest?
A: The mismatched tire is a dangerous situation. It should be replaced with the proper size immediately. And they have placed the tire on the worst possible end of the car, the rear. Mis-sized rear tires can lead to a loss of control under hard braking (the car can spin).
Can I use 235 tires instead of 255?
7 Answers. 8 people found this helpful. In a word, NO. The vehicle was designed for the 255 width tire, and you will lose serious amounts of highway traction with a tire that is 20 mm narrower.
Do bigger wheels use more fuel?
For any given speed, wheels with wider widths and larger diameters will increase momentum. This means more torque will be needed and hence more fuel will be consumed by the engine. Unless the larger diameter wheels are of a lightweight design, upsizing will affect fuel economy adversely.
Does 22 inch rims affect gas mileage?
End of dialog window. If your running 22s then your wheels and tiers are taller/wider and heaver then stock! All of this will hurt your gas mileage.
Why does gas mileage drop with new tires?
Your gas mileage can drop when you get new tires due to the full tread. This tread creates more rolling resistance than that of worn, well-used tires, thus affecting your vehicle’s gas mileage.
Will bigger tires raise my car?
1. Higher road clearance. The most obvious effect of larger tires is that they increase your car’s height. By elevating it several inches off the ground, you get better ground clearance – that is, the distance between the road surface and the lowermost part of the vehicle.
Why can I feel every bump in the road?
Feeling every bump If you start to feel every bump on the road, it’s a clear sign that there is a problem with your shock absorbers or struts, that needs to be checked. An easy check is the bounce test. Simply push your entire weight down on your car’s bonnet. Release and count the number of times the car bounces.
Why does my car feel bumpy when I drive it?
Tires are usually the first thing to check if your car’s ride feels strange. Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly.
How can I make my car less bumpy?
Do bigger tires affect acceleration?
Increasing the total wheel diameter will also increase the final reduction ratio and this has essentially two consequences: acceleration potential is decreased but a higher top speed can be reached. Naturally, these changes are directly proportional to the variation of size.
How much does it cost to recalibrate a speedometer?
In some speed related cases, this speedometer calibration can be very helpful. You can get it calibrated at almost any auto mechanic shop. The cost is usually around $75. Sometimes, charges can be reduced when it is clear that the speed was more comparable to a speeding charge than a reckless driving charge.
What is effect of changing tire size?
Wider Tire It results in a wider contact patch which provides better lateral grip, more grip on hard braking, less vehicle roll in corners and gives an improved, low-profile cosmetic appearance. This type of change in tire size can also benefit trucks, SUVs and crossover vehicles.
How much MPG do you lose with bigger tires?
Remember, power and economy are affected by transmission, drive axle ratios and tire size (revolution per mile). Change one, and you throw the equation off. With today’s new tires, there is virtually no difference in mpg due to tire size.
Does wheel alignment affect fuel consumption?
Misalignment can decrease gas mileage by up to 10%, writes Investopedia. Instead of rolling freely, misaligned tires drag. That means if your tires aren’t adjusted properly, you could be spending more money on gas. A wheel alignment could help you conserve fuel and fill up less often.
