What does 65 mean on tires?
The aspect ratio is a percentage.
It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width.
In other words, it’s sidewall height divided by tire width.
In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide..
Are big rims bad for your transmission?
Eventually, this could cause premature transmission failure. Larger and heavier rims will also cause the engine to work harder, which could hamper fuel economy and dull acceleration. Larger, heavier wheels could also have a negative effect on other components of the vehicle, such as wheel bearings.
Do tire sizes have to match exactly?
Generally, the worst issue you will cause by changing the size is an inaccurate speedometer. That said, the only dimensions you can change are the width and aspect ratio — never the wheel size, unless you buy replacement wheels — and you should always strive to keep the total height of the tire the same as the OEM.
Is a 60 series tire wider than a 70 series?
Generally speaking, a 215-60 series tire is wider and has a shorter sidewall then a 215-70 series tire would be and a 215-75 series tire would be taller and narrower then either the 70 series or the 60 series. The 215 designation would be the amount of weight the tire can carry at a given tire pressure.
Will bigger tires hurt my transmission?
Increasing Tire Size Will Reduce Your Vehicle’s Effective Gear Ratio. The increased size causes the tires to rotate slower to cover the same amount of ground. … If you are running an automotive transmission this can cause some serious strain depending on the current gear ratio if you choose not to regear your system.
What does the R mean in tire size?
radial constructionP identifies your tire as a Passenger Tire. … R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction. 16 The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches.
What is the best tire aspect ratio?
The aspect ratio is a percentage of the section width. So if you have a 70-series tire, that means the sidewall height is 70 percent of the tire’s overall width. Aspect ratio for most bias ply tires is somewhere around 80 or 90 percent.
What does the T stand for on tires?
temporary spareA “T” means it’s a temporary spare. Some tires get a “Z” or an “F” attached to the radial indicator, denoting a Z-rated tire (see service description below) or a run-flat tire.
What’s the difference between 265 75r16 and 265 70r16?
Going from 265/70 to 265/75 is increasing the height, or diameter, of the tire. The tire will be an inch taller. 265 is the width, so stock size is 265 millimeters wide. The speedometer will be a little off because the taller tire does not rotate at the same speed as the stock size.
What’s the difference between 235 and 245 tires?
A 245 tire is wider than a 235 tire. When you get to a 35 series profile is when the tires start to be low profile. 245 has nothing to do with the profile of a tire. A 245 tire is wider than a 235 tire.

What does 75 on a tire 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 70 mean on a tire?
Some may start with an LT prefix, used on heavy-duty trucks. The number 235 is the cross-section width in millimeters, while 70 is the ratio of sidewall height to cross-section width (70 percent). R means radial-ply construction and 16 is the wheel diameter, in inches.
What tire is wider 50 or 60?
The smaller the number, the shorter the sidewall and the wider the tire. In other words, a 50 series tire is shorter and wider than a 60, even though they both might be 275’s or whatever.
Which tire is taller 255 or 265?
17inches. Since you only specified the first, I can only tell you that the 265 is 10mm wider than the 255. It’s important to note that the outer diameter (how far the wheel rolls in one revolution) is slightly more for a 265 than a 255 at the same aspect ratio as the sidewall would be larger.
Can you put 75 tires on a 70?
The difference will be in the height. The sidewall of a 70-series tire will be 70% of the width, a 75 series will be 75% of the width. If you want the same HEIGHT in a 70 series, then you need to go wider in the width — about 219.
Can I use 235 tires instead of 225?
235/45 tires have a sidewall height of 105.75mm. The 225/45 tires will be shorter and will cause his speedometer to read higher than true. So short answer: Yes the tires will fit. They will, however, throw off your speedometer and will make the miles come onto the odometer faster.
Can I put wider tires on my stock rims?

Are 70 or 65 tires wider?
According to the Generic Auto Tire FAQs in Type2’s Technical Library, the shorter sidewall of the series 65 tire means a slightly wider tire that changes the car’s handling considerably; specifically, “more rubber on the road provides a better grip.” The series 65 provides better turn-in and stability compared to the …
Do bigger tires give better gas mileage?
Do larger tires get better gas mileage? The short answer is, no. … One of the reasons that larger tires will not lead to an increase in a car’s gas mileage is because they are heavier than smaller tires – every extra pound will, in essence, decrease a vehicle’s fuel efficiency.
Do bigger tires lower 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.
