What is the 3% rule for tires?
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. A common guideline is the “105% Rule”: The external rim width should be at least 105% of the tire’s actual inflated width. This ensures that the rim controls airflow better than the tire, maintaining laminar flow. For example, if your 28mm tire inflates to 30mm, the rim should be at least 31.

Recommended Tire Tread Depth New tires typically have a tread depth of 8 mm to 9. Minimum safe depth: Experts recommend replacing tires when the tread reaches 3 mm (4/32″) for optimal safety, especially in wet or snowy conditions.However, some tire experts recommend replacing tires when tread reaches 4/32 to maintain optimal performance and safety in wet conditions. An easy way to check your tread depth is with the penny test – just insert a penny into your tire’s tread groove with Lincoln’s head upside down and facing you.The minimum tread depth is 2/32 (1. This means that it is imperative to change your tires once this limit has been reached to avoid compromising your safety and breaking the law.The tire’s tread depth is sufficient. If you drive in snowy or icy conditions, consider replacing the tires.
