What size Tyres go on a Volvo V40?

Volvo V40 Tyre Options The most popular sizes used regularly are: 195/60 R15. 195/55 R15.

What are my size tires?

The two digit number after the slash mark is the aspect ratio which measures the tire’s cross-section to it’s width. If the tire size is 255/60 R16, the 60 means that the height is 60% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.

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 numbers on tires are interchangeable?

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.

What does 50r mean on tires?

50 is the two-figure aspect ratio. This percentage compares the tire’s section height with the tire’s section width. For example, this aspect ratio of 50 means that the tire’s section height is 50% of the tire’s section width. R indicates the construction used within the tires casing. R stands for radial construction.

What happens if you put wrong size tire on car?

Effects of Wrong Size Tires Choosing too tall of a tire can result in a vehicle prone to rolling over, a dangerous concern for any driver. Tall tires may also rub against the inside of the wheel well. While not immediately problematic, this rubbing can lead to steering issues over time.

Can wrong size tires damage transmission?

Wrong size tires do not damage the transmission. Although ill-fitting tires do not directly impact the transmission, it does impact the overall performance of the vehicle. Wrong size tires can cause a safety hazard as well as cause structural damage to the vehicle.

Do tires have to be exact size?

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.

Which tire is wider a 65 or 70?

The series number in a tire-numbering system refers to the aspect ratio of the tire’s sidewall height to its width. A series 65 tire’s height is 65 percent of its width, a series 70 tire’s height is 70 percent of its width and so on. These differences in height affect both performance and safety issues while driving.

How much taller is a 65 tire than a 60?

The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.

Can I put 60 tires instead of 55?

Yes…the wheel/tire combo has an overall diameter/circumference that should be maintained with 3% (+/-) the original spec. When you plus size wheels…the aspect ratio (height of the tire) decreases to compensate…and maintain the orig diameter/circumference.
