Sidewall cracks aren't completely out of the ordinary, and small cracks that are barely visible aren't likely to represent an imminent safety concern.How big does a crack have to be to fail an MOT?

The "3% tire rule" is a guideline suggesting that when changing tire sizes, the new tire's overall diameter (height) should not vary by more than ±3% from the original factory tire to maintain speedometer accuracy, proper function of safety systems (like ABS/Traction Control), and consistent handling. It helps prevent mechanical issues, inaccurate readings, and safety system malfunctions by keeping wheel rotation speeds similar to the vehicle's computer expectations, with a noted exception for some trucks/SUVs that can handle larger variations.Should I replace my tires if they are cracking?
However, if the cracks are deep or widespread, or if the tire's sidewall is compromised, the entire tire should be replaced. It is also crucial to practice regular tire maintenance to avoid future cracking issues. Keeping your tires properly inflated will help prevent unnecessary wear.What is the tire law in the UK?
The legal limit for the minimum depth of the tread on your tyres is 1.6 millimetres, across the central ¾ of the tread around the complete circumference of the tyre.

So, How Long Can You Drive on a Cracked Rim? The short answer: You shouldn't drive on a cracked rim at all. Even short distances can be dangerous, depending on the size and location of the crack.Why do modern tyres crack?
Rubber polymers expand in the heat and contract in the cold. Over time, this can lead to cracking – and the intensity of the UV rays can have the same impact. This combination – especially over a short period of time can drastically affect the tyre.What is the 105% rule on tires?
It has often been said that to have good cycling wheel performance, there is a "rule" that the external rim width of a wheel should be at least 105% of the width of the tyre, or that there is a simple relationship/formula that will predict the aerodynamic performance of a wheel based on rim width vs tyre width.What is the 25 cent trick on tires?
The "25 cent trick" (Quarter Test) for tires checks tread depth: insert a quarter upside down into the tread; if you can see the top of George Washington's head, your tread is worn below 4/32 of an inch and it's time to consider replacing your tires for better safety and traction, especially in wet conditions. This is considered a better indicator than the penny test, as 4/32" is a safer minimum than the penny's 2/32".What is the 7 7 rule for tires?
The 7/7 rule for tires is a guideline for switching between winter and all-season tires: install winter tires when daily temperatures consistently drop to 7°C (45°F) or below for seven days, and switch back to all-seasons after seven consecutive days above that temperature to maintain optimal traction and prevent premature wear. This rule ensures tires perform safely in their intended conditions, as all-season tires harden and lose grip in the cold, while winter tires wear too quickly in warm weather.How much cracking in tires is okay?
Is a Little Cracking on Tires Okay? A hairline crack is not usually enough reason to immediately stop driving on that tire, especially if the crack is the tire's sidewalls. Most cracks form in the sidewalls of tires, which is good because such cracks are less dangerous than cracks in the tread.Are small cracks in tyres okay?
Small cracks on the tread blocks of the tyre are a sign of normal wear and tear and aren't generally anything that you need to worry about. Deeper cracks could be a sign that the tyre is getting to the end of its useful life and may mean there's a risk of the tread separating from the rest of the tyre.Can I drive 2 miles on a flat tire?
No, you generally should not drive 2 miles on a flat tire, as it's enough distance to cause severe, costly damage to the tire, wheel rim, suspension, and brakes; you should drive only a very short distance (a few hundred feet) to a safe spot to change the tire or call for roadside assistance, unless you have self-supporting run-flat tires, which allow up to 50 miles but still require immediate repair. Driving on a flat puts the vehicle's weight on the sidewall or rim, leading to structural failure, and creates a serious safety hazard, even at low speeds.Are cracked tyres illegal?
