This law specifies the minimum thickness required for solid tires on vehicles. If a tire is between 3 to less than 6 inches wide, it must be at least 1 inch thick. For tires 6 to 9 inches wide, a thickness of 1.25 inches is necessary. Tires wider than 9 inches should be at least 1.5 inches thick.

This law explains how to measure the rubber of a solid tire. To do so, you measure the distance between the road surface and the closest metal part of the tire's base flange where the vehicle's weight presses down on the road.

This law mandates that the rubber on a solid tire must be of equal thickness all around the tire. The tire should be securely attached to its base and should not have any flat areas or bumps.

This law states that when you have dual solid rubber tires on a vehicle, the difference in size between the two tires shouldn't be more than one-eighth of an inch in diameter.

This law forbids vehicles on a highway from having tires with metal or wood parts sticking out beyond the tire tread. However, there are exceptions for certain situations and tire types. For example, you can use tire chains for grip on snow or ice. Some special pneumatic (air-filled) tires are allowed if they have very small amounts of exposed metal, particularly during bad weather or under certain conditions. Vehicles involved in road construction or repair, and emergency vehicles, can use specialized tires too. The law also permits tires with retractable metal studs, as long as the studs do not stick out when retracted, and only between November 1 and April 30 unless special permission is given.

This law says that from January 1, 1975, you can't sell or offer inner tubes for radial tires unless the valve stem is colored red or marked according to specific rules. Also, you can't put an inner tube into a radial tire unless it's made for that purpose.

This law requires drivers to use tire traction devices when driving on certain highways designated for such equipment. If the California Department of Transportation or local authorities require traction devices on vehicles weighing 6,000 pounds or less, drivers must install them on at least two drive wheels. Alternatively, if conditions allow, vehicles can use snow-tread tires with specific markings or designs for snow, provided they are in good condition. These tires are acceptable if they have markings like M-S or M/S, indicating their suitability for snowy conditions, or if they meet certain tread pattern requirements.

This law states that a person cannot sell, rent, install, or replace tire traction devices for highway use unless they meet certain safety requirements outlined in Section 605. Manufacturers of these devices must have proof from laboratory tests that the devices comply with these requirements before they can be sold.

If you drive a passenger vehicle or light truck weighing 6,500 pounds or less with four-wheel drive and snow tires, you can use it on roads where tire chains are usually required. However, you must keep tire chains in the vehicle, just in case, and you can't tow another vehicle unless it's disabled. Snow tires must meet specific standards.

You still need to use tire chains if weather conditions make snow tires alone unsafe or if there are signs requiring chains. The Department of Transportation or local authorities might also mandate chains regardless of your vehicle type or tire condition.

This law prohibits the sale or offering for sale of motor vehicle tires, except for commercial vehicle tires, that have been altered by cutting or burning new grooves into them. These altered tires, known as recut or regrooved tires, are not retreaded or recapped, meaning they are modified in a different way. The law aims to ensure safety by restricting the sale of potentially unsafe tires.

This law states that it's illegal to drive or allow the driving of any non-commercial vehicle on public roads if it has tires that have been recut or regrooved. A recut or regrooved tire is one where new grooves have been added by cutting or burning into the tire, not just retreading or recapping it.

This law says it's illegal for anyone with a retail seller's permit to sell or install tires with less tread depth than specified for use on highways. Generally, tires must have at least 1/32 of an inch depth in any two grooves, but steering axle tires on certain vehicles need 4/32 of an inch, and snow tires in traction areas need 6/32 of an inch. These rules don't apply when installing a spare tire in an emergency or to agricultural equipment. Tread depth isn't measured where certain tire features are present, and the department can set stricter rules if needed for safety.

This law section covers the standards and regulations for nonpneumatic tires, which are tires that don't rely on air pressure. Firstly, these tires must meet federal standards outlined in Part 571 of Title 49 of the Code of Federal Regulations. For certain purposes, nonpneumatic tires are treated the same as traditional air-filled tires by specific vehicle code sections.

The department has the authority to set additional regulations to ensure public safety, and anyone using or installing these tires on highways must follow those regulations. When creating these standards, the department will consider federal guidelines and advice from the National Highway Traffic Safety Administration.

Lastly, the definition of 'nonpneumatic tire' is aligned with the federal definition found in Section 571.129 of Title 49 of the Code of Federal Regulations.

This law allows the department to create rules about the quality and safety of vehicle tires to ensure public safety. When making these rules, they should look at the standards set by the Federal Highway Administration and the Rubber Manufacturers Association as a guideline.

This law makes it illegal for dealers or anyone with a retail seller's permit to sell or install a pneumatic tire on vehicles for highway use if those tires don't meet specific regulations. There's an exception for installing a spare tire during emergency services if the vehicle is stuck on a highway.

Additionally, it is prohibited for anyone to use a non-compliant pneumatic tire on highways.

This law makes it illegal for anyone selling tires, whether a dealer or someone with a retail seller’s permit, to sell or even offer tires that don't meet certain safety standards specified by related regulations. This applies to tires intended for vehicles used on highways.

This section requires the commissioner to hold public hearings and then create rules about how noisy tires can be. These noise rules must balance being quiet with what’s possible based on current technology, costs, and safety needs. These rules can be different for various types of tires and vehicles. Manufacturers have to prove to the commissioner that their tires meet these noise rules, and the commissioner can check them to ensure compliance. The commissioner must file these rules with the Legislature after a federal study on tire noise is available and they will take effect a year after filing.

The law also emphasizes that the commissioner should consider recommendations from the U.S. Department of Transportation before setting these noise standards independently.
