How wide is a 235 65R15 tire?

What size tires will fit on a 15 inch rim?

Does rim width need to be exact?

For your safety, and for the optimal ride, your rim width and tire size must be compatible. Why? Because the rim width has a direct impact on your tire’s contact patch, which changes how the tire interacts with the road and how your vehicle handles.

How do I know what size rims I need?

First, start with the wheel size for your vehicle. You can find that on the sidewall of the tires on your original wheels or the inside frame of the driver’s door. Check out Tire Size Explained (Reading the Sidewall) for more. The wheel diameter (in inches or millimeters) is the fifth set of numbers and letters.

How do I know what size rims will fit my tires?

Identifying Compatible Tire Sizes

The first is in the driver’s door jam. Open up the driver’s door and look within the door jam or on the door itself and locate the sticker that has your tire information on it. Here you will find the wheel (rim) and tire size your vehicle came equipped with from the factory.

How do you match tire size to rims?

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.

How do I know what size rim I need for my bike?

Using a tape measure, place the bottom of the tape at the lowest point of the tire (on the ground) and measure in a straight line to the centre of the bike wheel to find your wheel radius (as shown in the image above). Multiply your wheel’s radius by two to find the wheel’s diameter.

Is it better to have bigger or smaller wheels on a bike?

There’s no definite answer. On smooth surfaces, small wheels have less aerodynamic drag due to a smaller frontal area. Smaller wheels can also be built lighter (therefore easier to propel uphill). However, larger wheels theoretically provide slightly better rolling resistance (the effect of this is incredibly small).

Is it better to have bigger or smaller rims?

By choosing larger wheels, you can improve the stability of your car and reduce braking distances because of the increased surface area. During dry weather, experts prefer driving on larger wheels. They’re much more responsive mid-corner and give an overall better feeling on the road.

Does rim size matter for tire width bike?

Why does rim width matter? There are a number of reasons why rim width is important. Firstly, it determines which tyre sizes will fit safely. As a general rule, a very wide tyre on a narrow rim will be unstable thanks to inadequate support for the sidewalls and large air volume.

What happens if tire is too wide for rim?

If a tire that’s too wide for a rim is mounted, the tire shape becomes too tall and round, like a lollipop or lightbulb, and then it becomes floppy at the top because the casing is constricted. This can result in poor cornering performance and tire squirm.

What happens if rim is too wide?

The ratio between the section width and the rim width is pretty important. If the rim width is too narrow, you pinch the tire in and cause it to balloon more in cross-section. If the rim width is too wide, you run the risk of the tire ripping away at high speed.

Are wider tires more comfortable on a bike?

Though wider tyres don’t produce less rolling resistance than narrower tyres once you normalise for casing tension, they shouldn’t roll any slower either. Wider tyres are also likely to be more comfortable and grippier.

What tire width do pros use?

Race bikes: 23-25mm, increasingly up to 28mm

The common standard for many years was 23mm (it used to be even narrower) but that has changed as the pro peloton adopted wider tyres, with 25mm slowly becoming the default choice.

Is it OK to to go with wider tires?

To keep the suspension and speedometer functioning correctly, both the stock diameter and width of the wheels and tires needs to be maintained. As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim.
