What do the 3 numbers mean on tire size?
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 do tire sizes numbers mean?
The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.
What does 225 50R17 mean in tires?
What 225/50R17 Means. The number 225 identifies the tire section width (the measurement of the tire from sidewall to sidewall in millimeters). This tire has an aspect ratio of 50 means that the tire’s section height is 50% of the tire’s section width.
Which tire is taller 50 or 60?
Aspect ratio refers to the tire’s section height in relation to its section width, as a percentage. For example, a 60-series tire features a sidewall that is 60% as tall as the tire’s section width. A 50-series tire will feature a shorter sidewall, at 50% of section width.
Are thicker or thinner tires better?
Wider tires have an increased risk of hydroplaning on slippery or wet surfaces, but they generally provide better grip for dry surfaces. Narrow tires will offer better traction in slippery conditions, but they are generally better for lighter vehicles such as hybrids or electric cars.
Are 33 or 35 tires better?
33” tires are a bit more comfortable, while 35 inch tires offer better control. So, to summarize, if you plan on driving in rough terrain with many hills and valleys, go with 33 inch tires. If you plan on driving on flat ground or mostly on dirt roads, go with 35 inch tires.
Should I replace my tires at 3 32?
Low tire tread: Many mechanics recommend replacement when your vehicle reaches between 3/32 and 4/32 of an inch. This is especially true if you live in an area with severe climates to prevent hydroplaning and other inclement weather risks.

Do taller tires handle better?
Poor Handling
Large tires further add weight and limit the movement of your drivetrain. These slow down your vehicle’s acceleration and reduces its maximum speed. The increase in height, while helpful, also makes a car less stable. Overall, you end up with poor handling.
What size tire gives the smoothest ride?
Smaller wheel = smoothest ride quality, low stability, predictable handling, average road noise. Medium wheel = average ride quality, average stability, predictable handling, low road noise.
