Types of Tyres – 155 70 R13 vs 145 80 R13

155/70 R13 and 145/80 R13 are two types of tyres most commonly used on passenger vehicles such as cars, SUVs, and light trucks. The numbers indicate the tyre’s width and aspect ratio, respectively. The R stands for radial construction, which is a type of design that helps to increase the tyres durability and performance. The 13 indicates the wheel rim size in inches.

Benefits and Disadvantages – 155 70 R13 vs 145 80 R13

The main benefit of 155/70 R13 tyres is that they offer excellent road grip due to their wide tread width. This makes them suitable for vehicles which require better handling performance in wet weather conditions. They also provide good steering response and cornering ability. On the other hand, 145/80 R13 tyres are designed for vehicles which require more stability at higher speeds. These tyres provide a smoother ride due to their narrower tread width and lower aspect ratio than the 155/70 R13 tyres. They also offer better fuel efficiency as they have lower rolling resistance than wider tyres.

However, it should be noted that both tyre sizes have some drawbacks as well. The wider 155/70 R13 tyres tend to be noisier when compared to the narrower 145/80 R13 tyres due to increased road contact area and higher rolling resistance on dry surfaces. In addition, they wear out faster due to increased friction between the tyre and road surface which results in shorter tyre life span when compared to narrower tyres such as the 145/80 R13 size.

Tyre Terminology – Aspect Ratio & Rim Diameter

Aspect ratio is measured as a percentage of section height (tread width) compared to section width (sidewall width). For example, a 155/70 tyre has an aspect ratio of 70%, meaning that its section height is 70% of its section width or sidewall width. This means that it has a wide tread pattern for increased road grip but it also has a higher rolling resistance due to increased friction between tyre and road surface resulting in decreased fuel efficiency when compared to narrower tyres such as the 145/80 size with an aspect ratio of only 80%.

Rim diameter refers to the wheel rim size in inches (or cm) where 13 is standard for most passenger cars today, although there are variations depending on vehicle make and model so it is important to check your vehicles manual before purchasing any new tyres.

Specifications for Vehicles – 155 70 R13 vs 145 80 R13

The specifications for each type of tyre should always be checked before purchasing them as each vehicle manufacturer will have specific requirements depending on make, model and year of production. Generally speaking though, most passenger vehicles will use either 155/70 or 145/80 size tyres but it is always best practice to check with your vehicle manual before making any decisions. It is also important to note that these two sizes are not interchangeable; they must match exactly or they could cause problems with handling performance or ride quality depending on your vehicle type or driving style preferences.

Price Comparison – 155 70 R13 vs 145 80 R13

When comparing prices between different models or brands it is important to keep in mind that quality may vary significantly from one brand or model to another so it pays off to do some research before buying any new set of tyres; you get what you pay for so dont just opt for the cheapest option without considering quality factors such as tread life expectancy or warranty period offered by each manufacturer these can make all the difference over time! Generally speaking however, both sizes usually cost around the same price with only slight variations depending on brand name recognition or popularity among consumers at any given time so dont be surprised if you find similar prices across different brands when shopping online or at your local store!

Durability Evaluation

The durability of a tire is an important factor to consider when deciding which tire size is right for you. The 155 70 R13 and 145 80 R13 are both considered to be durable and long-lasting tires, but there are some differences between the two.
