What Size Tires Are Street Legal

Tire width: There is no legal limit to the width of the truck tires themselves, but they are not allowed to extend beyond the truck`s wings in virtually every state. Although it is well-intentioned, it is a very ineffective law. A simple and completely legal way around this problem is to attach wider fender flares to the truck than the deceived tires. These are counted as part of the wing, so the extremely wide tires are perfectly legitimate, as long as they don`t go beyond the wings. The most universal laws apply to the height of the bumper, which is of course affected by the size of the tire, but varies depending on the lift height built into the suspension. States regulate bumper heights to ensure that raised off-road trucks don`t have bumpers so high that they hit a car`s windows instead of sidewalls or trunk lids in the event of an accident. States have many different ways of defining an appropriate bumper height. An increased tire size usually requires an increase in body height to accommodate the tires. Many states such as New Jersey, Mississippi, and Georgia have laws that state that a vehicle cannot be modified to drive above or below 4 to 8 inches of stock ride height, regardless of tire size.

One of the few universal restrictions on tires in books is tire width. The tires themselves can be as wide as you like, but almost no condition allows the tires to protrude further than the vehicle`s fenders. One state that allows this is Kentucky, where you can practically hit a license plate on Big Foot and drive it. This law can be undermined quite easily in most cases by purchasing and installing fender flares wide enough to cover the tires. (v) has been grooved or recut below the original tread depth, except in the case of tyres specially designed with an additional under-profiled rubber intended for this purpose and marked as such. Many states allow larger vehicles to have larger tires and higher ride heights, which is usually determined by the truck`s gross weight. For example, Ohio only allows a front bumper height of 24 inches for those under 4,500 lbs, 26 inches for 4,501 to 7,500 lbs, and 31 inches for vehicles over 10,000 lbs. (1) use farm machinery equipped with tires whose projections do not damage public highways; and (g) A person who sells tires shall not sell or offer for sale a tire that is not safe under subsection (h). There is a common misconception about the type of guidelines used to regulate tire size on modified SUVs.

Most people mistakenly believe that the old federal system of maximum tire diameter is still universally enforced, but the latest enforcement system has more to do with overall vehicle dimensions and ground clearance, and varies from state to state. Measurements shall not be made in places with profile wear indicators or tie rods. A motor vehicle registered as a historic vehicle in accordance with § 803a is exempt from the tread depth requirements of this subsection. (b) It is prohibited to drive on a highway a vehicle equipped with a tyre having on its circumference a block, bolt, flange, horn, stud, stud or other protrusion of a material other than rubber protruding from the tread of the traction surface of the tyre, except as provided in paragraph (c), (d) and (e). However, a person may operate farm machinery with a tire that does not interfere with a road. A person may also use a reasonably proportioned tire chain on a vehicle if necessary for safety reasons due to snow, ice or other conditions that tend to cause a vehicle to skid.

(a) It is prohibited to drive on a highway of that State a special vehicle or mobile equipment equipped with a metal or plastic rail or a tire fitted with a metal that comes into contact with the surface of the road or that has partial contact of metal or plastic with the surface of the road.

except as provided in subdivisions c, d and e. The maximum height of the vehicle`s chassis in Tennessee depends on the total weight of the vehicle. The floor of the vehicle body shall not be more than 4 inches above the top of the frame. (i) exposed part of the belt material, cords or tyre layers. There are no laws specifically related to wheels found in Tennessee laws. It is illegal to modify the original steering system of a vehicle in Tennessee. The minimum diameter of the steering wheel is 12 inches. E.

It is unlawful for any person to knowingly sell, offer for sale or exchange or use motor vehicle tyres that do not comply with Subdivision A of this Division; or knowingly offer, exchange or use a motor vehicle tire that has worn out its original tread and has been grooved without additional tread so as to give the appearance of a new or reassembled tire. Every person who, on conviction, violates the provisions of this paragraph, shall be punished by a fine of fifty dollars or thirty days` imprisonment for the first offence, and shall be punished by a fine of two hundred and fifty dollars or three months` imprisonment, or both, for a second offence and five hundred dollars and six months` imprisonment for a third or subsequent offence. D. It is prohibited to drive or move on a highway of that State motor vehicles, trailers or semi-trailers equipped with metal tires in contact with the highway. Just as important as the height of the bumper is the height of the headlight. After all, you can have the brightest headlights in the world, but if no one can see you in their mirrors because your lights are 9 feet off the ground, then your headlights don`t do much good. Most states limit headlight heights to about 52 inches, but other states like Montana allow up to 72 inches. www.michigan.gov/documents/Loads_dim_87014_7.pdf four-wheel drive vehicles in Tennessee must have bumpers that are no less than 14 inches above the roadway and no higher than 31 inches. Car bumpers should be 22 inches or less. Bumpers must be at least 4.5 inches high. Allowed on any vehicle if necessary for safety reasons due to snow, ice or other conditions that tend to cause a vehicle to skid. www.legislature.mi.gov/(S(vgdobrcso0add4x4k2heex24))/mileg.aspx?page=getObject&objectName=mcl-257-710 iii) Worn or fallen below the minimum tread in 2 or more adjacent main grooves in 3 or more locations around the circumference of the tire.

The minimum permissible tread values are as follows: legis.la.gov/legis/Laws_Toc.aspx?folder=106&title=32 pounds…….. 2/32 inch front and rear (iv) Marked “Not for use on road”, “racing only”, “agricultural use only” or “unsafe for road use”. Like tractors, vans also have to pass under bridges on the highway. Most states give you 13 feet, 5 inches without a license, allowing you to clear any bridge on the highway. Keep in mind, however, that roads called parkways (like those in New Jersey) often have a bridge height of only 12 feet, and older cities like Chicago and Philadelphia have a large number of 10-foot bridges within the city limits. Tennessee began requesting emissions testing in April 2005. Since 01.07.2014, emissions testing is only required in Hamilton, Rutherford, Sumner, Williamson and Wilson counties. (f) No person shall drive a vehicle on a highway if a tire used on the vehicle is not safe in accordance with clause (h). (h) A tire is unsafe if it is in any of the following conditions: (e) a person may drive a vehicle on a highway equipped with a tire in which windshield handles or tire studs are inserted, if the person is a law enforcement officer operating a law enforcement vehicle, a person driving an ambulance or rural carrier of the United States Postal Service; who drives a vehicle owned and maintained by the rural freight forwarder as a condition of employment in the postal service.
