6 The benefits of using Radial Technology: The drawbacks of using Bias-Ply Technology:In bias-ply tires the tread & sidewalls share the same casing pliesAll sidewall flexing is transmitted to the tread, resulting in:deformation in the tread contact patchfriction with the groundrapid wearreduced tractionhigher fuel consumptionBias PlyRadialThe benefits of using Radial Technology:Outstanding traction due to flat stable crown & larger footprintBetter distribution of pressure in footprint resulting in reduced soil compaction & greater flotationReduced working time due to less tire slip, greater productivityReduced fuel consumptionLonger tread lifeComfort & handling on the road

8 Tire Components CORE TIRE KNOWLEDGE Innerliner 1 2 3 4 5 chapterPARTS OF A TIREInnerlinerThe innerliner is a rubber compound bonded to the inside of the cord body that retains air under pressure. It has no cord reinforcing and functions as an innertube in a tubeless tire.
9 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIREBead BundlesTire bead bundles are large copper, brass, or bronze plated high tensile steel cords wound together. Tire beads occasionally include some type of fabric wrap to retain the bead shape prior to the curing process. The body plies of the tire are looped around the bead bundles to hold the plies in place. The bead holds the tire on the rim.
10 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIREBead FillerThe bead filler is a hard rubber compound used to provide stability to the lower sidewall and bead area.
11 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIRECord Body[ tire casing ]The cord body provides tire strength and transmits cornering forces from the tread to the wheel. Rubber coated cord, called body plies, make up the cord body. Body plies can be polyester, rayon, or nylon. Polyester is the most common cord body. The area of the body ply that wraps around the bead is called the turn up.
12 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIRESidewallThe sidewall is the area of a tire from the bead to the tread. It forms a protective covering for the cord body. Sidewall rubber compounds resist aging, cracking, cutting, and snagging, and contain sidewall treatments such as white lettering.
13 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIREBelt Plies[ package or system ]Belt plies are two or more strong layers of cord under the tread area. The main function of the belt system is to provide stability to the tread area of the tire. They assist in improving tire mileage, impact resistance, and traction by giving the tread area extra strength and stability. The most common cord material used in the belt plies is steel.
14 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIRECap PlyThe cap ply also found in some tires is similar to belt edge strips only full width instead of just on the belt edges. These components may be used for a number of reasons, but most commonly to enhance high speed performance.
15 CORE TIRE KNOWLEDGETire ComponentschapterPARTS OF A TIRETreadThe tread is the portion of the tire in contact with the road surface. The tread compound and shape are designed to optimize the wear, traction, handling, fuel economy, and cut resistance characteristics of the tire given the tire’s intended use.

17 CORE TIRE KNOWLEDGETire DimensionschapterTIRE AND RIM DIMENSIONSTread WidthThe tread width is the distance from outer edge to outer edge of the tread. You can estimate differences between the existing and the replacement tires by comparing the tread widths. You can estimate changes in fender well and frame clearances by dividing the tread width differences between the existing tire and the replacement tire by two.TREAD WIDTH
18 CORE TIRE KNOWLEDGEchapterTire DimensionsTIRE AND RIM DIMENSIONSSection WidthThe section width is the width of a new tire when mounted on the tire’s measuring rim, including normal sidewalls but not including protective side ribs, bars, raised letters, or decorations. You can estimate the width differences between the existing and replacement tires by comparing the overall section widths. You can estimate changes in sidewall to fender well, frame, and suspension clearances by dividing the overall section width differences between the existing tire and the replacement tire by two.TREAD WIDTHSECTION WIDTH

20 Tire Dimensions CORE TIRE KNOWLEDGE Aspect Ratio [profile or series] chapterTire DimensionsTIRE AND RIM DIMENSIONSAspect Ratio [profile or series]75 SERIESThe aspect ratio, also known as the profile or series, is the ratio of the section height to the section width. For example, a 75 series tire is approximately 75 as high as it is wide.Lower aspect ratio tires, such as 60 series, generally offer performance advantages over higher aspect ratio tires, such as 70 or 75 series. They provide more responsive handling, more stability, and better high-speed capabilities.Height= 75% of Width70 SERIES60 SERIES
21 CORE TIRE KNOWLEDGETire DimensionschapterTIRE AND RIM DIMENSIONSOverall DiameterThe overall diameter of a tire is the distance from tread surface to tread surface while inflated but not loaded. It is twice the section height plus the nominal rim diameter. You can estimate the height difference between the existing and replacement tires by comparing the overall tire diameters. You can estimate changes in the tire to fender well clearance and vehicle ground clearance by comparing the radiuses (diameter divided by 2 = radius) of the two tires.SECTIONHEIGHTOVERALLDIAMETERRIMDIAMETER

27 3) Switching from Radial to Bias or Tube Type to Tubeless Changing Tire Fitment1) Tires marked “Front Tire” or “Rear Tire” should be mounted only in their stated wheel positions.2) Some motorcycle wheel positions may only be fitted with radial, bias, or bias belted tires. Consult owners manual, local dealer, or Tire Manufactures Technical center for the correct tire/wheel combination for your vehicle.3) Switching from Radial to Bias or Tube Type to TubelessTowing Trailers1) Towing trailers behind your motorcycle may contribute to motorcycle instability. It may also cause tire stress through overload. This overloaded condition could cause damage to the tire which could result in a sudden tire failure and/or accident. Most tire manufactures do not warranty tires fitted on motorcycles fitted with trailers2) Sidecars should not be fitted to motorcycles without approval from your vehicle manufacturer. If approval is obtained for sidecar fitment to your vehicle, the tire manufacturer should be consulted, before fitment, to ensure proper tire fitment and load caring capacity

33 Dealers and Sales Reps need more tire knowledge 1) Dealers have limited or no knowledge of how the motorcycle tire warranty system works.2) Working with the larger distributors to increase dealer tire knowledge3) Seminars like this will increase consumer knowledgeCupping on front tires (heavier bikes)1) Three reasonsA. 90%-Air Pressure-Air Pressure- Air PressureB. 8%-MechanicalC. 2%-Tire tread designWear on one side of the tire1) Always alignment related (same as on your 4 wheeled vehicle)

We have to see the tire with the problem to determine what is wrong with the tire.
