What do the 3 numbers on tires mean?
B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. This may also be referred to as the section width. C: ASPECT RATIO The forward slash separates the tire width number from the two-digit aspect ratio.
What is P245 in tire size?
Looking at the same number sequence, locate the three-digit number directly following the tire type. In the example “P245/50R20 102V,” the number indicating the tire width is 245. This tells you how wide your vehicle’s tires need to be to fit onto the wheels.
What is a 245 tire equal to?
245: The width of the tire, from sidewall to sidewall, in millimeters. A 245 is 245 millimeters, or 24.5 centimeters, wide. The tread width is actually somewhat smaller than the tire’s actual width.
What does the number 245 mean on a tire?
The next number, 245, in our example, indicates the tire’s width in millimeters from sidewall to sidewall. So, this one is 245 mm wide. The number after that, 70 in our example, stands for the ratio of the height to its width, or the aspect ratio.
Whats the difference between p265 and P245?
As their name suggests, 245 tires are 10.43 inches wide, while 265 tires are 9.65 inches wide. That may not seem like a big difference, but it can actually have a pretty significant impact on your car’s performance. Generally speaking, wider tires offer better grip and traction than narrower ones.
Do tire sizes have to be exact?
Width and diameter are the two factors that determine tire and rim compatibility. For diameter you’ll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17″ diameter wheel. There’s a bit more flexibility when it comes to wheel widths.
Is a 70 or 75 tire taller?
The higher the number, the taller the sidewall (and vice versa). From the foregoing, it appears that tires with the same section width should have the same width regardless of aspect ratio.
Can I change my tire size without changing rims?
When changing your tire size might be acceptable. It’s possible to change the size of your tires without actually changing the diameter. One example is if you want larger rims – you can buy tires that compensate for the larger rims by reducing the “height” of the outer tire.

The short answer: yes. Tires can make a big difference in the number of miles a driver gets to a tank of gas. In fact, 20% to 30% of a vehicle’s fuel consumption and 24% of road vehicle CO2 emissions are tire-related. Tires affect vehicle fuel efficiency primarily through rolling resistance.
Does increasing tire size affect gas mileage?
For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
Do bigger tires make your speedometer faster or slower?
Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, causing it to need to travel more distance per revolution than the original equipment tire.
Does changing tire size affect alignment?
When the tire size is different from the factory, a car’s alignment will need to be adjusted after a tire change. This is because tires that are wider or taller than original equipment tires stretch the suspension slightly and cause changes in camber and caster angles, as well as toe angles.
Do larger diameter tires ride better?
While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber.
