What is the difference between a 225 and 245 tire?

A 245 tire is approximately 10mm higher than a 225 tire. This also means that a wider tire is also going to increase your car's ride height. This is because wider tires tend to have a higher aspect ratio which essentially means that they are not only wider but also taller as opposed to narrower tires.

Do wider tires make a difference?

There's a reason why the majority of cars have wide rather than narrow tires. Overall, wider tires are better for dry surfaces and for high-performance vehicles. Greater surface area allows for better day-to-day traction and durability.

Do 245 tires fit 255?

No difference. Keep in mind 255 and 245 are sidewall width and having nothing to do with tread width. Depending on manufacturer a 245 could have more tread width than a 255.

What does the number 245 mean on a tire?

245: The width of the tire, from sidewall to sidewall, in millimeters. A 245 is 245 millimeters, or 24.5 centimeters, wide. The tread width is actually somewhat smaller than the tire's actual width.

Can you put bigger tires than recommended?

If planned or installed incorrectly, up-sized tires may also rub the wheel well, brake calipers, or vehicle frame, potentially wearing down any parts they grind against. At Tires Plus, we generally recommend against up-sizing your vehicle's tires.

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 bigger tires affect transmission?

This includes the drivetrain, transmission, brake system, and all the associated parts within those systems. This can also affect your odometer and speedometer as larger tires will have a larger circumference, causing you to travel a little bit further per each complete tire rotation.

Can I use a different tire width?

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.

What's the best speed rating for tires?

As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety. The "Limited V" category of 250 km/h (149 mph) was then created, and eventually the "Z" speed rating was added as the top speed rating.

How much bigger is a 255 tire than a 245?

While the exact dimensions of a 245 or a 255 tire can vary somewhat between tire manufacturers, for any specific manufacturer a 255 tire will have a wider section width (bulge or tread width) than a 245 tire, the difference being 10 mm.

What number on a tire makes it wider?

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.

Which tire is wider 245 or 265?

The 265 tire is wider at 10.43 inches, while the 245 tire converts to 9.65 inches.

Do wider tires get better gas mileage?

For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.

Are wider tires better for comfort?

The volume of air in a tire will particularly affect their driving comfort. The larger the rim diameter, the less air will fit in the tire. High-profile tires with plenty of space for air are more comfortable than wide, low-profile tires.

Do wider tires slow you down?

Myth 1: Wider Tires Are Slower

Some people realized that in theory, wider tires are faster due to their shorter contact patch, which deforms less as they roll. But the thinking was that in practice, the lower pressure at which wider tires must run limited their performance.

What does R mean on a tire?

“R” stands for the construction method of the tire indicating the tire is a radial tire. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tire. In the example, 94 means the tire can carry 670kg.

How long are tires good for?

On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.

What does the T or H mean on tires?

The “T” or “H” on tires pertain to their speed ratings. A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.

Do tire sizes have to be exact?

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.

Can wrong size tires damage car?

Unfortunately, altering the tire size of a vehicle without thorough and careful consideration is a decision that can really bite. Fitting the wrong tire size can cause damage to a vehicle, and is a real safety hazard as well.

Do bigger tires make your speedometer faster or slower?

Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, causing it to need to travel more distance per revolution than the original equipment tire.

Do bigger tires affect engine?

Bigger wheels mean heavier wheels, and heavy wheels force your engine to work harder and use up more gas. How much gas you use will be dependent on the strength of your engine. The loss in miles per gallon will be more apparent if your car has a smaller engine.

Can you change tire size on the same rim?

Wheels and tires are not interchangeable words. Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size.

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.
