What size tires come on a 2015 Suburban?

Can I use 18 inch rims instead of 19?

Despite what your car salesperson may have told you, it’s OK to get an 18-inch spare to go with your 19-inch wheels.

Are 18 or 20 inch wheels better on a truck?

The short answer is, not really. There is really no benefit in going from 18 inch to 20 inch aside from nicer aesthetics. With that said if your goal is to have a nicer appearance 20 inch wheels will certainly give you a larger overall diameter which makes for a much cleaner design.

What size are my stock rims?

Look at the backside of the wheel.

If it’s an original wheel, you’ll ordinarily see imprinted on the spokes the make, origin country, OEM number, and size. But for a steel stock wheel, you may find the wheel size on the front side, or the face, of the wheel. For example, the size of the wheel will look like “18×7 ½ ”.

Are 6×5 5 and 6×139 7 the same?

A: Yes, 6×5. 5 is a 6×139. 7 (it’s metric vs. standard measurements).

What is stock rim size?

To figure out your actual stock wheel diameter, you can simply look on the tire. For example, you see 225/50R16 on your tire, the diameter of the wheel is referenced by R16 which is a 16” diameter wheel. Some tires may also reference the diameter of the factory original wheel in millimeters.

What is the standard rim size?

Wheel diameters can vary, but they typically range from 13″-24″ (or higher for specialized low profile fitments). Only wheels and tires of the same diameter can be safely mounted together, meaning you can only mount a 16″ tire on a 16″ wheel.

Do bigger rims affect gas mileage?

For any given speed, wheels with wider widths and larger diameters will increase momentum. This means more torque will be needed and hence more fuel will be consumed by the engine. Unless the larger diameter wheels are of a lightweight design, upsizing will affect fuel economy adversely.

Do rim and tire size have to match?

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.

Does tire rim size matter?

Many drivers give little thought to the sizes of their wheels and tires except for cosmetic purposes. But, wheel size — and the size of tires you put on them — matter. Using improper tires can be costly and sometimes even dangerous.

What tire size can I substitute?

As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of your existing tires’ diameter — assuming your current tires are what your owner’s manual recommends.

Can I use 17 inch tires instead of 18?

When you move to a larger wheel diameter (such as from 17 to 18 inches), you need new tires to match. Those tires need a lower profile (or sidewall height) to maintain adequate clearance when they go over bumps and potholes, which makes the suspension fully compress and rebound.

Do bigger tires give a smoother ride?

As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. However, if you go too crazy and change your wheel size too much, it can cause some problems.

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.

Why do I feel every bump in the road?

Feeling every bump

If you start to feel every bump on the road, it’s a clear sign that there is a problem with your shock absorbers or struts, that needs to be checked. An easy check is the bounce test. Simply push your entire weight down on your car’s bonnet. Release and count the number of times the car bounces.
