Does Tire Sidewall Size Matter?

Can I use 235 tires instead of 245?

plenty of tires that you can select without having to change tire size.

The quick answer is yes you can replace 245/50-18 tyres with 235/50-18 but they will have 10mm (0.4 in) smaller overall diameter.

Will only slightly effect speedo and odometer – ie speedo will read about 1.5% high..

How much difference in tire diameter is acceptable?

Generally, it is recommended to not exceed a 3% difference when changing from the OEM size on a non-modified vehicle. A green row means that the alternate tire diameter matches the calculated tire diameter.

Do wider tires affect gas mileage?

Increasing the width of a tire can impact fuel economy as well. Wider tires create a larger contact patch, the area of the tire actually touching the road. While this is good for performance, it can create a higher resistance to coasting, meaning that the engine will have to use more power and fuel to maintain speed.

What tire is wider 60 or 70?

Generally speaking, a 215-60 series tire is wider and has a shorter sidewall then a 215-70 series tire would be and a 215-75 series tire would be taller and narrower then either the 70 series or the 60 series.

What is the difference between 50 and 55 on tires?

The “50 or 55” is the aspect ratio between width and sidewall not a direct measurement. 190/50 …the sidewall is 50% of the tire width so 75mm tall. Or, it’s 9.5mm difference if you’re not using common core math. Or, 5.5mm more than stock.

What happens if you drive with different size tires?

A: The mismatched tire is a dangerous situation. It should be replaced with the proper size immediately. … Mis-sized rear tires can lead to a loss of control under hard braking (the car can spin). The one tire left on the car is almost an inch smaller in diameter.

How much bigger is a 215 tire than a 205?

The diameter of the 205 is 26.3 inches and for the 215 the diameter is 26.7 inches. That is 0.4 inches of difference meaning that it would raise the height of the trailer by 0.2 inches. Trailer tires should always be inflated to the maximum psi indicated on the tire.

Do wider tires wear faster?

As with automobile tires, the wider the tire, the less pounds per square inch on the road surface, the slower the wear. … The higher the air pressure you run in your tires, the more quickly they will wear out because there is less tire in contact with the road surface.

Can I use 225 65r17 instead of 235 60r17?

Both fit 17 inch rims, so one obstacle is out of the way. 235/65R17 has a sidewall height of 153 millimeters (65% of 235 mm), while 225/60R17 has a sidewall height of 135 mm (60% of 225 mm). … You are reducing sidewall height by 18 mm (about 3/4″), so your car will be lower by this amount.

Can I use 235 tires instead of 225?

Obviously, you will need a certain kind of tire depending on how you use your vehicle. Due to this, a 235 tire might not be better than a 225 tire, or vice versa, but depending on your situation, one tire might serve you better than the other.

Can wrong size tires damage transmission?

Increasing Tire Size Will Reduce Your Vehicle’s Effective Gear Ratio. The increased size causes the tires to rotate slower to cover the same amount of ground. … If you are running an automotive transmission this can cause some serious strain depending on the current gear ratio if you choose not to regear your system.

What happens if one tire is smaller than the rest?

If yours is a FWD car and you put a smaller diameter tire on the left front, the left will go slower than the right, your car will keep pulling to the left. … You should not keep driving with a spare tire, because the other three tires would not wear evenly, creating a lot stress for those three tires.

Can I use 185 tires instead of 205?

The max you can run is a 185. If they are a 7″ wide rim, then a 205 can be used.

Can I use 265 tires instead of 235?

Is it better to have a wider tire?

The larger the rim diameter, the less air will fit in the tire. … From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires.

Does aspect ratio matter on tires?

The aspect ratio affects steering stability. Generally, the shorter the sidewall, or the lower the aspect ratio, the less time it takes to transmit the steering input from the wheel to the tread. … Aspect ratio also impacts ride. A low-profile tire usually has a stiffer ride than the standard aspect ratio of 75 or more.

Can I use 215 tires instead of 205?

For example, if your car has 205/50-16 tires and you want more grip, you can install a 215-width or maybe even 225-width tires. … For example, you can install a 195 tire in place of a 205 tire.

Will bigger tires affect gear ratio?

When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear. You do not want go too low in an effort to increase power to the wheels and/or relieve stress in the rest of the drivetrain.

Is it OK to put smaller tires on your car?

Narrower tires will reduce braking, acceleration and handling performance. Shorter tires will likely increase fuel consumption by keeping revolutions per minute (rpm) higher at cruise speed, and any aerodynamic gains aren’t likely to offset the fuel consumed by this additional rpm.

Is it bad to have wider tires in the back?

When a rear-wheel-drive car has a lot of power, it can cause wheelspin easily which is why wider rear tyres can give better traction. … While it’s fine to put narrower tyres on the front and wider on the back, it’s pointless to put wider tyres on just one side of the car.

A smaller tire lets you put more force from the wheels to the road, and theoretically accelerate faster. However if your car cannot maintain traction, then it won’t accelerate any faster as you’ll just be spinning the wheels and sliding around. So in this case, adding larger tires will decrease the force you exert.

Is it OK to have different size tires front and back?

How far off is my odometer with bigger tires?

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. Smaller diameter tires will effect odometer reading more than larger tires.
