What is the difference between 65 and 70 tires?
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. Safety and fuel efficiency are the aspects where these tires differ. The 265/70R18 is slightly narrower and therefore has slightly less rolling resistance and possibly a tiny boost in fuel efficiency. However, the 275/65R18 is stable in handling and also has great grip, especially in rainy weather or during turning.The 265/65R18 is smaller, with a diameter of around 31. The 275/70R18, on the other hand, is larger with 33. The difference in size affects their applications. The 265/65R18 is compact and better for mixed-use.
What is the 3% tire rule?
The 3% rule states that when replacing tires, the new tire’s diameter should not differ from the original by more than 3%. This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle.Shouldn’t change anything. Just a inch taller. The tire is heavier (depending on type and class of tire). Also if same wheels or different can also make a difference.
What is the 7 7 rule for tires?
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. Ottawa’s CAA Members can avoid the tire swap lineups at on-site vendors and save money with our economical new Mobile Tire Change. The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes.

How much difference in tire size is okay?
Generally, you don’t want to go with tires that have a diameter that is more than 3% different from the factory tires. It’s also a good idea to consult with a trusted mechanic before switching to larger or smaller tires. Increased Wear and Tear on Vehicle Components Wrong-sized tires can put extra strain on your vehicle’s drivetrain, suspension, and braking systems. If the tires are too large, they may rub against the wheel wells or fenders, damaging both the tire and the vehicle body.
