# What does the 65 mean on a tire?

The aspect ratio is indicated on the tire sidewall as 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 this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide.

## Can I fit 65 Tyres instead of 55?

Properly, no. A 205/65R16 sized tire has a much taller sidewall compared to a 205/55R16 tire. If you used the taller sidewall tire you would very much lessen the handing, stability and control of your vehicle.

## How much taller is a 60 tire than a 55?

## Can I use 205 55R16 at the place of 205 60r16?

## Does the middle number on tires matter?

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.

## Can you use a slightly different tire size?

Once you choose a tire size for your vehicle, you’ll want to stick with that size when you buy replacements. The reason for this is that a differently sized tire can confuse your speedometer and even cause damage to your vehicle’s anti-lock braking systems and stability system calibrations.

## Will 215 55r16 fit on 205 60r16?

They are essentially the same circumference, so as long as the added width will fit in your wheel well, there should be no problem using them.

## Can you use tires with different aspect ratio?

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. So, if you widen the tire, you may need to decrease the aspect ratio, and vice versa.

## Can you mix and match tire sizes?

The short answer is that, in general, manufacturers do not recommend tire mixing at all. For optimal safety and performance, it is recommended that vehicles are fitted with the same tires to every wheel position on your car.

## Does it matter what size tire you put on your car?

One of the main things to remember no matter what size you choose, is always replace a tire with the same size tire. A different size tire will not only throw off your speedometer, but could also do serious damage to antilock brake systems and stability system calibrations.

## Do bigger tires give a smoother ride?

## What tires wear out the fastest?

Front tyres tend to wear faster, up to 2.5 times faster on some cars. The left front tyre has it the hardest. It is the most heavily loaded and responsible for transmitting most of the steering during right hand turns.

## Do larger tires increase gas mileage?

However, for freeway driving at high speeds, having larger tires can help increase the vehicle’s fuel efficiency. Is this because while it is easier to get a smaller wheel and tire moving than a larger one, once moving, the engine works harder to make the smaller wheel cover the same distance as a larger one.

## Do bigger tires make you go faster or slower?

Larger wheel diameters can result in faster and more composed handling; however, it can also result in slower acceleration capability. While there are a few disadvantages for any vehicle when increasing the wheel and/or tire size, curb appeal usually outweighs them.

## Do I need to recalibrate my speedometer after bigger tires?

Discount Tire recommends that you recalibrate your speedometer every time you change your tire size. This is so you are able to safely operate on the road, ensuring you are not accidentally speeding or dangerously below the flow of traffic speed.

## Do tires last longer if you drive slower?

Higher driving speeds cause more heat to build up in the rubber, breaking down the tire more quickly than at slower speeds. Similarly, taking turns at slower speeds and avoiding skidding on turns also helps the tire last longer.
