You can find your car’s tyre size written on the sidewall of your current set of tyres, in your vehicle’s handbook or on a sticker in the door jam or inside the fuel cap door. When buying new tyres you should only go for ones that have these same numbers to ensure a good fit.
Can I put a different size tyre on my car?
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.
Should you replace all 4 tyres at once?
With four-wheel drive vehicles, you may need to replace all four tyres when one gets worn out or has a puncture. This is because 4×4 systems rely on all four tyres when operating.
Should all 4 tyres be the same?
Primarily, you should avoid mixing different tyre brands and different tread patterns. There are rare exceptions for approved mixed-tyre fittings, but in general, manufacturers do not recommend tyre mixing at all.
How do I find tyre size for my car? – Related Questions
How much difference in tire size is acceptable?
When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure.
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.
Can I use 225 tires instead of 215?
Yes, you can. But only if the rims on your car can accommodate tires that are 10-20 millimeters wider. Bear in mind that wider wheels require more fuel due to their increased rolling resistance. Again, wider tires are more costly than narrower ones because they need more rubber during construction.
Can I use 215 tires instead of 205?
Using 215 mm tires instead of 205 mm tires will result in better traction in dry conditions which helps to improve acceleration. However, 205 mm tires are less prone to aquaplaning and result in better fuel economy and less road noise compared to 215 mm tires.
How much taller is a 215 than a 205?
A 205 and a 215 tire differ 0.4 inches when it comes to tire diameter which means that 215 tires are also 0.2 inches taller in comparison.
Can wrong size tires damage transmission?
Unfortunately, oversized tires can affect your transmission. The main issue that affects the transmission comes from a lower drive ratio. The bigger the tire the worse the ratio becomes. This issue can be overcome, however, by re-gearing the transmission along with the tire change.
What happens if you have different size tires?
What happens if you have a different sized wheel on one side of your car? Your differential, which allows the wheels to turn at different speeds so that you can more easily go around corners, will be working overtime and damage could occur. The suspension of your car will be working harder on one side.
Is it better to have bigger tires in the front or back?
According to Tire Review, new tires should always go in the back. Rear tires provide the vehicle stability, and if they have little tread, then stability is lost.
Why are front tires smaller than rear?
Since the motor drives the rear wheel and forces it in a forward direction the downward force to the rear tire needs to be greater than in the front. So bigger tires and more body weight over it equals more traction better power transfer.
Can I use 235 tires instead of 245?
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.
What is the difference between 235 65R17 and 245 65R17?
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. On vehicles, especially newer vehicles, there is very little space to go to a larger tire without making other modifications.
Can I use 235 65R17 instead of 245 65R17?
Yes, a size 235/65R17 tire will fit the same wheel as a 245/65R17 size tire.
What does the 245 mean on a tire?
The next number, 245, in our example, indicates the tire’s width in millimeters from sidewall to sidewall. So, this one is 245 mm wide. The number after that, 70 in our example, stands for the ratio of the height to its width, or the aspect ratio.
Which tire is bigger 245 or 265?
As their name suggests, 245 tires are 10.43 inches wide, while 265 tires are 9.65 inches wide. That may not seem like a big difference, but it can actually have a pretty significant impact on your car’s performance. Generally speaking, wider tires offer better grip and traction than narrower ones.
Are wider tires better?
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.
Will different size tires fit the same rim?
You can change the size of your tires with the same rims, as long as the tire and rims have the same internal diameter. Tires are flexible, however, so the width and height may be changed. Be sure to pay attention to manufacturer specifications when choosing tires.
