extra-Deep-Tread Tires' Lateral Stiffness effects

Many drivers are aware of the feel of the trucks used on a daily basis in fleets, and are sometimes sensitive to the ride dynamics of fitment changes of new tire designs on the vehicle .

One of the sensations drivers notice is a side-to-side motion . This motion is the byproduct of what is commonly referred to as lateral stiffness .

The lateral stiffness of a tire is due in large part to inflation pressure, as well as the tire’s tread depth . Both of these factors vary over time . Reduced inflation pressure and deeper tread depth results in lower lateral stiffness .

Therefore,someusersmaycommentonexperiencingaslightswayingwithnewlyinstalledextra-deep-treaddrive tires, especially under full load or after replacing worn drive tires .

Bridgestone Firestone Chassis Dynamometer Test Guidelines for Truck/Bus Tires

i. Background

Vehicle manufacturers and many maintenance facilities conduct in-place vehicle testing on twin-roll chassis dynamometers . Testing is usually conducted over a short period of time on empty vehicles . If the following procedure is not adhered to, irreversible damage may occur to the tire .

ii. Procedure

Topreventexcessiveheadbuildupinthecenterofthetiretread,followthe recommended time period based on roller diameter as listed below:

Load: These time restrictions apply regardless of the actual load and are, in fact, more critical when the vehicle is tested without a load .

iii. Precautions

To avoid the possibility of irreversible tire damage and/or failure during testing, it is important that the following precautions be taken:

• DonotexceedthetimeandspeedrestrictionslistedinpartII.

• Allowatleastonehourcooldownbetweentests.

• Whenitisanticipatedthatatestwillexceedthetime/testvalueestablished,awornor“slave”tireshouldbe used in place of the new tire for testing purposes .

Questions regarding test procedures, loads, etc . should be directed to your Regional Field Engineering Office .


Maximum Allowable Time by Roller Diameter8-5/8" Roller 18" Roller3.5 minutes 6 minutes

Maximum Allowable Speed is 55 mph.

Aerosol Tire Sealer/inflatorsAerosol tire sealer/inflators have been used by large numbers of motorists each year and an undetermined number of tires now on the road, which have been filled with these devices, may have combustible gases in their air chambers .

Please read carefully and make sure all your employees read the attached publications that have been approved and distributed by the Rubber Manufacturers Association and the National Highway Safety Administration .

TiRe oR RiM RePAiR SAFeTY BULLeTiN FACTS YoU ShoULD KNoW...It is difficult to determine whether a tire has been inflated with a flammable aerosol type tire sealer/inflator . Therefore, if your establishment repairs or works on rims or on pressurized, rim-mounted tires, you should handle all of them as if they contain a flammable tire sealer-inflator .

Thegasesinthesealer/inflator,whichcanbepoisonous,arecombustibleinsidethetire.Anexplosioncan occur if ANY ignition source is present . Even the insertion of a plug into a steel-belted tire could causeanexplosion!

Proper safety precautions to avoid ignition of flammable gases MUST be followed during the repair or maintenance of ALL tires or rims .

Failure to follow these precautions and procedures may result in serious or even fatalinjury.

PReCAUTioNS YoU ShoULD TAKe...

All tires should be handled as if a flammable tire sealer has been used . Do not rely upon the customer, even if he advises you that one has not been used . Customers may neglect to tell you or even may have forgotten they used a sealer/inflator .

Always make sure that the repair area is well-ventilated so that any gases that are present will not accumulate .

Never weld or use a cutting torch on a wheel or rim without first completely removing the tire from therim.Otherwise,explosionsresultinginpossibleseriousorfatalinjurycanoccur,evenintheabsence of flammable sealer/inflator .

Donotuseatirerasp,plugoranyobjectwhichcouldcausesparksonatireorrimwithoutfirstcompletelyremovingthetirefromtherim.Theseignitionsourcescouldleadtoanexplosion.

Do not permit smoking or any flame, spark or other ignition source in the area where tires or rims are being kept .

Never add air to a tire treated with a flammable sealer/inflator without completely removing the flammablegas.Airaddedtoatirecontainingflammablegasmaymakeitmoreexplosive.

Remove the valve stem completely to release the tire pressure in a well-ventilated area, away from sparks or other ignition sources .

After the pressure has been released and before making any repairs, remove the tire from the wheel rim .

If you believe a sealer/inflator has been used, wash the inside of the tire with a detergent/water solution and rinse thoroughly . Allow the tire to dry before repairs are made .

innertube Storage

Innertubes should always be stored in a sealed enclosure . If the seal is damaged or broken, reseal the enclosureorrepackagetheaffectedtubestopreventprematureozonecrackdamageontubes.Exposuretoweather, open doors, sunlight, electric motors and fans can cause premature aging of the rubber compound, especially when folded . In addition, tubes stored in tires can be similarly affected if unprotected by a flap or rim .

Tubes with ozone crack damage should be replaced. Do not place these in service.

Mounting Tubeless Truck TiresProper mounting practices are mandatory to help ensure uniform tire/wheel assemblies for application to heavy duty trucks which use 22 .5 and 24 .5 bead diameter tubeless truck tires . Failure to follow the industry recommendations for mounting uniformity may result in improper tire bead/wheel fit and can lead to vehicle vibration and irregular tire wear .

Bridgestone recently conducted a tire mounting study involving tubeless tires of different brands, aspect ratios and bead diameters on new and used steel and aluminum wheels . Bridgestone tires included in this study were R299, R194-LP, R293 and R194 designs .

Results of the evaluation showed that regardless of the item combination checked, uniform assemblies were obtained when the following three practices were performed:

1 . Clean the wheel or rim

2 . Lubricate the tire and beads AND WHEEL/RIM BEAD SEAT

3 . Check the assembly for concentricity

1 . A used wheel/rim should be cleaned by wire brushing to remove rust, scale and build-up . Painting the cleaned metal with primer or anti-rust paint is recommended .

2 . Before assembling tire and wheel/rim, lubricate tire beads and wheel/rim seat with a vegetable oil-based lubricant formulated for tire and wheel/rim use . Do not use petroleum- or solvent-based products, as they cause rubber deterioration .

Failure to lubricate the wheel/rim as well as the tire can lead to a non-uniform assembly .

Thebestinitialbalanceisobtainedbymatchingthetire'slightspot(markedbyayellowdotorcircle)atthewheel/rim valve .

3 . To check the assembly for concentricity of a tire and wheel/rim, measure the distance between the tire-flangeinterfaceandthecircumferentialringmoldedintothetiresidewallatfourlocations(90degreesapart)aroundthetire-flangecircumference.Distancesmeasuredshouldbewithina2/32"(1.5mm)rangefor acceptable uniformity . If the ranges in distance within the same side of the tire are greater than this, break down assembly, re-lubricate and remount the tire .

Following these practices will reduce vehicle vibration and irregular wear occurrences . The first step in investigating these types of complaints should be the measurement of tire and wheel/rim concentricity to determine if non-uniform mounting is present, and the probable cause . If so, break down assembly, re-lubricate tire and wheel and remount tire .

Steam Cleaning Tires

CAUTioN: Steam cleaning can damage a tire and render it unserviceable .

AtmanybusinessesthroughouttheUnitedStates,itiscommonpracticetouse“steamcleaningequipment”towash trucks and tires .

Nozzletemperatureonsteamcleaningequipmenttypicallyreaches280°F.

When a steam cleaning nozzle is held too close to the sidewall of a tire for as short a time as 45 seconds, a small spongy blister may appear on the sidewall . When this blister is cut open, one will observe reverted rubberresultingfromtheexcessivelocalizedheat.

Steam cleaning of tires can be harmful to tires when the nozzle is concentrated in one spot for a period of time .
