Which tire is taller, a 65 or 70?
These numbers show the aspect ratio, which is the tire sidewall height in percentage to width of the tire. The width of Sidewall is directly proportional to the aspect ratio, a 70 aspect ratio means the sidewall height is 70% of 265mm while 65 aspect ratio means it is 65% of 265mm. If a tire has an aspect ratio of 70, it means the tire’s height is 70% of its width. Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series, but a typical trade off can be ride harshness.
Is 65 a low profile tyre?
This is also known as the aspect ratio. The lower the number, the more ‘low-profile’ the tyre. R 14 88H That is the sidewall height of the tyre as a percentage of the section width. R – This means the tyre is of radial construction. This is the internal diameter of the tyre. This is the load index. How much weight the tyre can carry.
What is the 7 7 rule for tires?
The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes. Install winter tires when daily temperatures drop to 7°C (45°F) or below for seven consecutive days. Remove them in spring after seven straight days above 7°C. If you leave them on too long, your winter tires will degrade quickly. So, when is the right time to swap? The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. The reverse is also true for transitioning to winter.
What is the 3% tire rule?
The 3% tire rule is a guideline for upsizing tires. It recommends keeping the new tire’s diameter within 3% of the original to avoid affecting performance and safety. It’s highly recommended to use the exact tire size recommended for your car. However, in a pinch the tire width and aspect ratio can be changed slightly and still fit on your rim. Although this will still work, keep in mind it may have adverse effects on the performance of your car.
