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 tire gives the smoothest ride?

Smaller wheel = smoothest ride quality, low stability, predictable handling, average road noise. Medium wheel = average ride quality, average stability, predictable handling, low road noise.

Do taller tires increase gas mileage?

Taller tires will also raise the vehicle higher further from the ground and can, according to BF Goodrich, increase its wind resistance and decrease its fuel economy.

What is the advantage of 20-inch wheels over 18 inch wheels?

They can provide additional control. Since 20-inch tires typically have a smaller sidewall, they tend to retain relatively more rigidity on the road. The additional rigidity may give drivers of certain vehicles slightly better handling when cornering.

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 ”.

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.

What does LT mean on a tire?

An “LT” on your sidewall before that long string of numbers and letters denoting your tire size signifies the tire is a “Light Truck-metric” size; it was designed for use on a vehicle that carries heavy cargo loads or tows a large trailer.

Are LT tires better for towing?

Light Truck Tires

Their “heavier” construction also makes them superior for hauling heavy loads and navigating rough terrain. Additionally, LT-metric tires often provide better handling when towing heavy equipment or supplies, which makes them a top choice for hardworking trucks and SUVs.

Will LT tires ride rough?

LT tires are built for heavy vehicles, so their stiffness can give your vehicle a harsh ride, and since they require higher tire pressure, they can throw off your vehicle’s TPMS (Tire Pressure Monitoring System, a safety feature that alerts you to improper pressure in your tires).
