How wide are 225 tires


Helpful Tire Info - BUDNIK

Our chart shows the overall section width, the outside diameter, the sidewall height and the recommended rim width range.

If your car requires something unique, start with picking the tire for the end of the car that is the most difficult.

If you’ve mini-tubbed the rear for example, and are going to run a big tire with less brand/tread/size choices, start by figuring out that size and what your options are. Then see if the those tire manufacturers also make a matching tire for your front.

We’ve included the sidewall height of the tire as a quick way to make sure your front tire doesn’t have a taller sidewall than your rear tire when doing staggered sizes. That’s usually not a good look.

There is a recommended rim width range for any given tire size with the ideal width usually around the middle of that spread. Some things to consider are how much sidewall bulge you want to see and most importantly, how wheel width affects the tires ride, handling and wear characteristics.

For grip and even wear the wheel width needs to allow for a good contact patch where the tread meets the pavement.

A wider wheel tends to make the tire more responsive to steering inputs but also taken to extremes can make the ride harsh because the sidewall doesn’t flex as easily.

A narrower wheel can give up some of that responsive handling and will tend to give a softer ride because the sidewall has more curve that flexes more easily.

Rules to follow

  • Mount tires with the same exterior diameter (or slightly smaller)
  • The speedometer must not read below the actual speed. When travelling at 25 to 75 mph, the speedometer can read up to 10% more than the actual speed
  • Mount tires with a load index equal to or greater than that of the original tires
  • Mount tires with a speed index equal to or greater than that of the original tires (except for snow tires. More information)
  • Check to see that rim width and diameter are suitable for the tire
  • When using different front and rear tire dimensions on SUVs and vehicles equiped with anti-lock and anti-slip systems (ABS, ASR), the distance travelled over one turn must be taken into account
  • Make sure that any dimension changes you plan to make do not pose mechanical problems (required space, extending beyond the vehicle body...)
  • strong>Check with a motor vehicle inspection station that the dimensions of the mounted tires are approved for the use of your vehicle.
  • The below table provides you the tire widths you can fit compared to the rim width.
    e.g. for an 6" rim, tires whose width is 175, 185, 195 or 205 can be fitted.

Tire size change table

Every motorist eventually comes to the moment when he wants to make a certain upgrade of the car. But any modification entails not only design changes, but also the improvement or deterioration of running gear. But is it possible to change tire sizes? Undoubtedly, this also applies to car tires with disks. Replacing tires and wheels is one of the most popular tuning manipulations. Everyone knows that wider and higher tires give the car solidity and attractiveness, even if the modified vehicle belongs to the budget category. But is increasing tire size really a good idea? Let's look at three options for replacing rubber with a factory dimension of full profile, low profile or extra low profile tire replacement options.

To begin with, it should be understood that the native size is chosen by designers for a reason. It is formed based on the technical capabilities of the car, its traction and acceleration characteristics. Also, the initial size is affected by the shape of the car body, weight, and its purpose.

Tire size is determined by three values, for example, in a tire with a size of 185 65 R14 they will be interpreted as follows:

  • 185 - profile width (not tread!) in mm;
  • 65 - profile height in % of the profile width;
  • R14 - internal diameter in inches.

Changes to certain parameters have consequences in terms of clutch quality. Moreover, each case is private, there is no specific rule on how this or that modernization will affect the ride. In case of a planned change, it is necessary to consult with a specialist. Below is a table of replacement tire sizes.
