What size tire goes on a 8.5 rim?

Will a 245 tire fit a 8.5 rim?

245/40 on an 8.5 fits perfectly.

How do you match a tire to rim size?

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.

What does 7.5 mean on rims?

“7.5” — the width of the rim from bead lip to bead lip—the widest part of the inside of the rim. “J” — refers to the bead profile. It’s rare that you’d find something besides “J” on passenger cars.

What do rim size numbers mean?

What do rim size numbers mean? This number represents the distance between the two bead seat areas where the tire is sealed onto the wheel. The wheel size also includes its width and offset. The width is the distance from each bead seat (from inside to the outside).

What does 7.5 mean on wheels?

Wheel markings explained

7.5 is the wheel size, meaning it is 7.5 inches wide (1 inch = 25.4mm) 16 is the wheel diameter, also expressed in inches.

What does 17×8 mean for rims?

Wheel sizes are defined with the calculation: (diameter x width), so that a 17” diameter wheel might be 17×7”, 17×7. 5” or 17×8”. Widths tend to scale up with the diameter, so that while you will almost never see a 17×5” or a 17×10” wheel, a 14×5” or 19×10” wheel are standard sizes.

Is bigger rim size better?

One of the most significant benefits of larger wheel size is increasing the vehicle’s stability because the wheels cover a wider surface area and increase vehicle stability. Larger wheels significantly reduce the braking distance, while smaller wheels require a greater stopping distance.

Does width matter on rim size?

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. That’s why rim width plays a key role when replacing rims or modifying your tire size.

What rim size is best for performance?

The sweet spot for most of our muscle cars and track cars is 17- or 18-inch wheels. This isn’t just my opinion, but that of many industry insiders. The 12- or 13-inch rotors usually chosen by the road racing crowd fit in these wheels just fine, and don’t need the additional clearance given by a 19-inch or larger wheel.

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.

What is the advantage of 18 inch wheels?

Pros of 18-Inch Wheels and Tires

Because 18-inch tires have a larger sidewall, they are typically more flexible than ones with a smaller sidewall. Your tires act as shock absorbers and can provide a greater cushion when going over bumps and potholes.

Does 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.

What size tire is best for gas mileage?

With today’s new tires, there is virtually no difference in mpg due to tire size. As with many questions related to cars and tires, the answer to this question can have nuances, conditions, and variations.

Do wider tires ride better?

Wider tires have an increased risk of hydroplaning on slippery or wet surfaces, but they generally provide better grip for dry surfaces. Narrow tires will offer better traction in slippery conditions, but they are generally better for lighter vehicles such as hybrids or electric cars.
