When it says R18, it means that it has a radial-ply construction and it fits an 18-inch rim. A tire can only be installed on a wheel that is identical to its inner diameter.

What is the difference between 18 and R18?

No-one younger than 18 may see an ’18’ film in a cinema. No-one younger than 18 may rent or buy an ’18’ rated video. Films rated R18 are to be shown only in specially licensed cinemas, or supplied only in licensed sex shops, and to adults of not less than 18 years.

Do 18-inch tires wear faster?

Yes, at least in theory, a smaller tyre will wear slightly faster for the same other conditions.

Can you put a bigger tire on the same rim?

As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half inch (12.5 millimeters) increase in rim width.

Do bigger tires affect gas mileage?

The short answer: yes. Tires can make a big difference in the number of miles a driver gets to a tank of gas. In fact, 20% to 30% of a vehicle’s fuel consumption and 24% of road vehicle CO2 emissions are tire-related. Tires affect vehicle fuel efficiency primarily through rolling resistance.

Will bigger tires hurt my transmission?

Increasing Tire Size Can Wear Out Your Drivetrain & Transmission.

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.

What tire size 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 are the pros and cons of larger tires?

Do wider tires handle 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.

Is it better to have wider tires in the front or back?

A wider front tyre makes sense in many applications, however, when handling and ride comfort are considered. A wider tyre will generally provide better cornering traction than a narrower one, assuming appropriate inflation pressure.

Do wider tires need more PSI?

Thus, just to maintain the same stress on the walls of the wider rim (and on the tire casing), you must decrease your tire pressure by 5.3psi. Using the same analysis, the pressure in your 90psi front tire must drop to 85.2psi with the wider rim.

Why put bigger tires on back of car?

Advantages of larger rear wheels in an RWD car? Having a larger diameter rear wheel increases the amount of rubber that contacts the road along the axis of the vehicle which increases your acceleration potential. When you accelerate, much of your vehicle’s weight shifts to the rear.
