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.

Expert Reply: You might be able to replace a 235/65-17 with a 245/65-17 tire. The tires you have now, 235/65-17, are about 9.25 inches wide and 29 inches tall. The 245s on the other hand are 9.65 inches wide and 29-1/2 inches tall.
Is it OK to change tire size?
Installing larger wheels and tires, also known as “plus-sizing,” can affect the accuracy of its speedometer and odometer, handling, steering response and more. If done incorrectly, changing the tire size can be detrimental to the safety of your vehicle.
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 put different size tires on the front and back?
For optimal safety and performance, it is recommended that vehicles are fitted with the same tires to every wheel position on your car. That means having the same brand, size, tread pattern, load index, and speed rating on the front and rear tires.
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.
Can I use 205 55R16 instead of 195 55R16?
A 205/55/ R16. is wider than a 195 therefore the ratio (that’s the middle figure) needs to be less, 50 or 45 in your case, otherwise the overall diameter of the tire will be larger, that may cause problems.

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.
Do tire sizes have to match exactly?
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.
Are thicker or thinner tires 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.
Do thinner tires save gas?
Tire Size. 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.
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.
Do thinner tires go faster?
This means that the narrower tyre produces more friction and thus more energy, meaning less effiency in terms of rolling speed. The narrower tyre deforms more, negatively affecting speed.
What happens if you put thinner tires on a car?
Smaller tires can cause inaccurate information from your speedometer and odometer, create transmission shifting issues, cause anti-lock brakes to malfunction, and may even trip your check engine light.
Can I put a thinner tire on my rim?
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.
