Tire Safety Tips for Tractor, Construction, and other OTR Tires


  • Sumo

Tire Safety TipsLast week was designated as  National Tire Safety Week by the Rubber Manufacturers Association or RMA. While this campaign is generally dedicated to passenger tire safety for a safe summer travel season, it is the perfect time for us to talk about tire safety for specialty tires such as tractor, farm, construction and other OTR tires. Checking your tires should always be part of your daily inspection before operating any type of machinery. Besides the obvious risk of a tire blow out or failure during operation, other factors can affect your overall operational safety. Proper tire maintenance is important to maintain traction. Tires that show signs of damage, have excessive tread wear or are underinflated will not perform safely.

This is also important for your bottom line- when your tires are not performing properly, you are not getting the optimum performance from your equipment. And a tire failure causes very costly downtime! So take the time to properly inspect your tires for signs of wear, cracking, rim damage and inflation.

Tire Safety for Tractor Tires, Construction Tires & OTR Tires

Most safety tips will be true for any type of specialty tire. While there are some safety recommendations specific to say farm tires or OTR tires, let’s start with some basic good practices.

Proper Tire Selection

Tire size is just the starting point when it comes to specialty and OTR tires. Weight or load carrying capacity, applications, surface and environment for use, traction requirements and equipment type are just a few factors to consider. This is why it may be best to speak with an expert before you purchase. Ken Jones offers exceptional product support and will know how to find the right product for your needs and your budget. So just give us a call at 1-800-225-9513, email your questions to sales@kenjones.com, or live chat with a tire expert on our website.

Load And Inflation Pressure

Maintaining the correct inflation pressure at all times will give you the best results from your tires. This is true for almost any type of tire. Keep in mind that it takes tires up to 24 hours to cool after completing a job. Because of this, it is recommended that you check and adjust inflation pressure after long breaks or weekends.

Safety Starts with Proper Demounting & Mounting Procedures

Due to the size and weight of these tires, following proper procedures for demounting and mounting is extremely important. The task of servicing tires and wheels can be extremely
dangerous and should be performed by trained personnel only, using the correct tools and following specific procedures. If you have any doubt in performing any step in the demounting, mounting, or inflating process STOP! Seek assistance from a qualified person. The link below from Titan Tires gives their guidelines for proper mounting and demounting procedures. It also has useful tips about using the proper size rim and lubricants. For best practices you should follow safety guidelines and procedures as recommended by the manufacturer for your tires and equipment.

Liquid Ballasting

When extra traction is needed, especially in agriculture and OTR (off road use), liquid ballasting can be used to help improve traction, stability and higher adherence on the terrain. When filling tires with liquid ballast, it is recommended not to exceed 75% of its volume, in order to leave an air reserve of at least 25% of the tire volume. It is very important to use proper inflation pressure as recommended by the manufacturer with reference to the loading conditions in order to maintain safety and performance.

In harsher climates, anti-freezing agents such as calcium chloride or magnesium chloride can be used. It is highly recommended that these operations are carried out by a professional technician only.

Proper Handling & Storage

Avoid storing tires for more than a few months. Store in areas that are dark, cool, and free of dirt and oils. Try to store as far as possible from running electric engines. For more proper handling, transportation & storage tips from BKT Tires, click here.

Safety Tips More Specific to OTR or Off the Road Tires

OTR Tires or Off the Road Tires are one of the hardest working categories of tires we sell. Proper maintenance, selection and use of these tires improves performance, safety, and most importantly- reduces costly downtime!

The information below came from a previous post specific for this particular niche.
Off-the-road tires are designed for mining, roadwork,forestry/timber hauling and construction jobs. Always consult the manufacturer or an experienced OTR Tire expert before using these tires for any other uses. Improper handling, maintenance and driving habits can damage these costly tires, increasing the operating cost of your equipment.

The following tips came from the Alliance Tire Website recommendations for their OTR Tire Line:

Proper Tire Selection

When purchasing a tire, look for the design that best suits the job or application. “Tire size and P.R. should be determined after weighing the loads on each wheel according to accepted procedures. Generally, it is recommended to choose the tire that carries the load with the lowest inflation pressure. After selecting the tires and mounting them do not overload the vehicle, for example, by adding sideboards.”

Load And Inflation Pressure for OTR Tires

Maintaining the correct inflation pressure at all times will give you the best results from your tires. This is true for almost any type of tire. Keep in mind that it takes tires up to 24 hours to cool after completing a job. because of this, it is recommended that you check and adjust inflation pressure after long breaks or weekends.

  • Tire pressure should be checked every month, and occasionally during the work day. When checking during work times, make sure you take into account that heat build-up will raise the pressure up to 15 psi. If inflation pressure exceeds the additional 15 psi, you should reduce the load or the driving speed.
  • Never lower inflation pressure by bleeding. This only increases heat build-up.
  • Cover all valves with caps to prevent dirt penetration.
  • “Load and inflation pressures should be determined according to length of the haul.” See the tables below provided by Alliance. “When the haul exceeds 5 miles, round-trip, consult the tire manufacturer.” Maintaining the haul road can significantly increase the life of a tire.
  • “It is permitted to use regular skid depth tires without dry ballast in transit, on the condition that the following rules are carefully observed:1.The vehicle must be unloaded during transit.2. Maximum highway speed must be limited to 30 mph. For wide-base tires, the speed is 20 mph.3. Proper inflation pressure must be checked and maintained according to manufacturer’s instructions or the tables on the following pages.4. 30-minute intervals should be observed for cooling off every 50 miles or after 2 hours of sustained operation, whichever comes first.5. A minimum one-hour midday stop should be observed during full day operation.”

    Proper Driving Techniques

    To get maximum performance from off-the-road tires, it is important to use proper driving habits. Avoid things like: chuck holes, strong spinning, sudden starting or breaking maneuvers, high speed cornering, and locking one wheel for sharp turns. Any of these maneuvers can harm your tires and shorten their working life.

    Mounting and Dismounting of OTR Tires

    Alliance also recommends correct mounting and dismounting procedures. It is important to take all safety precautions. Remember, many severe accidents result from carelessness in mounting or dismounting.

    Mounting/Dismounting Safety Tips

  • “Before mounting the tires on the vehicle, check the wheels and rims and make sure that the vehicle is in perfect mechanical condition. Upon completion of the mounting process, check the clearance between the wheel and the vehicle all around. For duals, install a permanent rock ejector to prevent damage from wedged rocks.”
  • “Duals should not vary in their overall diameter, more than ¼” for tires of up to 8.25” cross section, and ½” for tires with cross section of 9.00” and above. If this is not adhered to, the larger tire is likely to fail prematurely. Never try to make up for larger differences by changing the inflation pressure.”

http://www.KenJones.com choosing the right loader tire: what you need to know before you buy what you need to know before you buy tire size tread design tread depth weight requirements tire size tire size can be located on the sidewall of the tire and are usually two sets of numbers, the tire width (sidewall to sidewall) and the rim diameter. For example 20.5X25 20.5 inches wide and the rim diameter is 25 inches. If the tire is bias, then there will ne an "x" before the 25 If the tire is radial, there will be an "R" before the 25 Most OLDER loaders are bias and he newer loaders come with radial tires as original equipment. tread design Other than what comes Original Equipment on the loader from the factory, surface usage is the main factor in choosing a tread design. An aggressive tread design, called an L-2,is designed for soft surfaces, such as garden nurseries and mulch yards, while the hard surface or rock tread, called an L-3, is for quarry and road use. Load Capacity The size of the loader and the work load determines the weight requirements of the tires or tire ply rating. Many loader tires come in 12 ply and up to 20 ply ratings.the higher the ply rating, the more weight carrying capacity of the tire. A tire's ply rating can be found on the sidewall of the tire.
