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 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’s the difference between a 245 and a 255 tire?
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.
Can I use 245 tires instead of 255?
You can do whatever you like but the 245 width tyres will have a smaller diamater so may affect your speedometer reading…
What is the difference between 225 and 245 tires? – Related Questions
Is it OK to have 2 different size tires?
Having two different-sized tires on the same axle is generally not a good thing. If the diameter of the two tires is close, then the rolling radius is about the same, so in the short term, you probably won’t have any damage, but long term, you run the risk of messing up your car’s differential.
What is a 245 tire equal to?
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.
What is a 255 tire equal to?
255 (Tire Width): The tire width is 255 millimeters from sidewall to sidewall (just over ten inches). 45 (Aspect Ratio): The tire’s sidewall is 45% of the tire’s width, which means the sidewall is about 114 millimeters or just over 4 inches.

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 mismatch tire sizes?
Primarily, you should avoid mixing different tire brands and different tread patterns. There are rare exceptions for approved mixed-tire fittings, but in general, manufacturers do not recommend tire mixing at all.
Is it better to have bigger tires or smaller?
Overall, bigger tires and wheels are better for increasing your vehicle’s traction. However, bigger tires also mean bigger price tags, according to Consumer Reports. Try to find the best balance between size and your budget.
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.
Can wrong size tires damage transmission?
Increasing Tire Size Can Wear Out Your Drivetrain & Transmission.
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.
Does tire size affect horsepower?
The rotational inertia, which factors in the mass of the wheel, is likely contributing to the difference. Most simply put, heavier wheels and tires means less power realized against the road.
Do bigger tires affect your speedometer?
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.
How far off is my odometer with bigger tires?
1/8” tread wear on a 36-inch tire reduces the circumference by 0.8 inches. Over the length of 1 mile, this adds up to 33.6 feet. After “actually” traveling 157 miles, the odometer will be “off” by 1 mile. It will read 158 miles.
Do bigger tires increase acceleration?
Newton’s Second Law dictates that the force on an object is equal to its mass multiplied by its acceleration. So, increasing your wheel size will decrease the driving force from your wheels which will culminate in a decrease in acceleration of said wheels.
