    10. 10. THE TYRE
    11. 11. CONTENTS• SIDEWALL MARKINGS• WHAT DO THE NUMBERS ON TYRE SIZES MEAN• SPEED AND LOAD RATINGS• TRUCK TYRE PATTERNS, HOW TO RECOGNISE WHICH ARE STEER,DRIVE AND TRAILER PATTERNS ON :-• 1,GOODYEAR TYRES• 2,DUNLOP TYRES• 3,FULDA TYRES• 4,SAVA TYRES• RETREADS
    12. 12. WHAT DO TYRE SIZES MEAN
    13. 13. WHAT DO THE NUMBERS ON A TYRE SIZEACTUALLY MEAN• TYRE SIZES ARE NORMALLY SPLIT INTO 3 PARTS• IE :- 315/80/22.5• THE FIRST IS 315 THIS IS THE SECTION WIDTH IN (MILLIMETRES)• THIS IS THE WIDTH OF THE TYRE AT ITS WIDEST POINT(WHEN INFLATED ON THE RIM)• THE SECOND 80 IS THE ASPECT RATIO• THE SECTION HIGHT AS A% OF THE SECTION WIDTH• THE LAST 22.5• THIS IS THE WHEEL DIAMETER IN INCHES• THIS IS THE SAME PRINCIPLE FOR CAR AND VAN AS WELL AS TRUCK TYRES
    14. 14. Position 1TYRE MARKINGSThe tire section width is the linear distance in millimeters or inchesbetween the outsides of the sidewalls of an inflated tire excludingelevations due to labeling (markings), decorations, or protectivebands or rims.
    15. 15. Loaded SectionSection Width (SW)SO THE FIRST NUMBER OF THE SIZE 315/80/22.5IS 315 THIS IS THE WIDTH OF THE TYRENORMALLY MEASURED IN MILLIMETRES.ALTHOUGH TYRES ARE SLIGHTLY FATTER IN THEMIDDLE THINK OF THIS SIZE AS THE TREADWIDTHTYRE MARKINGS
    16. 16. Position 2TYRE MARKINGSSection height is half the difference between the overall diameter andthe nominal rim diameter, expressed in % of tire width. In the course oftire history the shape of the tire has changed from an almost circular tireto flatter, wider tires. This has changed the relationship or aspect ratio(a/r) of the tire section height to the section width from 100% to 70%,60%, 50%, and even lower.
    17. 17. Loaded SectionSection Width (SW)SO THE SECOND NUMBER OF THE SIZE315/80/22.5 IS 80THIS IS CALLED THE ASPECT RATIOWHAT THIS IS IN LAYMANS TERMS IS THEHIGHT FROM THE WHEEL TO THE GROUND AS A %OF THE WIDTH OF THE TREAD AREA.SO THIS IS 80% OF THISTYRE MARKINGS
    18. 18. Position 4TYRE MARKINGSThis diagram shows the actualpoint of measurement whichdetermines the nominal rimdiameter.Rim diameters are measured both in inches or millimeters.For conversion purposes, 1 inch = 25.4 mm.Rim diameter22.5 indicates the rim(wheel) diameter.
    19. 19. TYRE MARKINGSLoaded SectionSection Width (SW)THE THIRD NUMBER OF THE SIZE 315/80/22.5 IS22.5THIS IS THE WHEEL DIAMETER MEASURED ININCHES(P.S. WHEELS ARE SOMETIMES CALLED RIMS)
    20. 20. LOAD ANDSPEED RATINGTYRE MARKINGSTHE LOAD RATING ON THIS TYRE IS 156/150 THE REASON THERE ARETWO NUMBERS IS THE HIGHER NUMBER IS IF THE TYRE IS NOTPAIRED TOGETHER SO HEAT CAN ESCAPE BOTH SIDES OF THETYRE.THE SPEED RATING ON TRUCKS IS ONE OF J,K,L,OR M(see next slides)
    21. 21. SPEED RATINGSTHE SPEED RATING ON TRUCK TYRES IS NORMALLY L OR M FOR TRUCKS ANDJ FOR TRAILERS.IT IS VERY IMPORTANT THAT TRAILERS IN 17.5” OR 19.5” GET FITTED WITH JRATED TYRES AS 17.5 & 19.5 SIZES COME IN J AND L OR M. AND CONVERSELYTRUCKS MUST NOT GET FITTED WITH J RATED TYRES.(TRAILER TYRES ON 385/65/22.5 ALTHOUGH YOU CAN GET A STEER TYRE INTHIS SIZE THERE IS NO WRONG SPEED RATING ).
    22. 22. LOAD RATINGSAS WELL AS THE SPEED RATING ON TRUCK TYRES THERE IS A LOAD RATINGEG 315/80/22.5 156 LTHIS IS JUST AN INDEX NUMBER RELATING TO A TABLE (BELOW) WHICH GIVES THELOAD A TYRE CAN CARRY. BUT AS FAR AS YOU ARE CONCERNED AS LONG AS YOUWORK WITH THE SPEED RATING THE LOAD RATING WILL BE RIGHT.LI KG LI KG LI KG LI KG LI KG LI KG LI45 40 140 80 450 120 1400 160 4500 200 14000 2401 46.2 41 145 81 462 121 1450 161 4625 201 14500 2412 47.5 42 150 82 475 122 1500 162 4750 202 15000 2423 48.7 43 155 83 488 123 1550 163 4875 203 15500 2434 50 44 160 84 500 124 1600 164 5000 204 16000 2445 51.5 45 165 85 515 125 1650 165 5150 205 16500 2456 53 46 170 86 530 126 1700 166 5300 206 17000 2467 54.5 47 175 87 545 127 1750 167 5450 207 17500 2478 56 48 180 88 560 128 1800 168 5600 208 18000 2489 58 49 185 89 580 129 1850 169 5800 209 18500 24910 60 50 190 90 600 130 1900 170 6000 210 19000 25011 61.5 51 195 91 615 131 1950 171 6150 211 19500 25112 63 52 200 92 630 132 2000 172 6300 212 20000 25213 65 53 206 93 650 133 2060 173 6500 213 20600 25314 67 54 212 94 670 134 2120 174 6700 214 21200 25415 69 55 218 95 690 135 2180 175 6900 215 21800 25516 71 56 224 96 710 136 2240 176 7100 216 22400 25617 73 57 230 97 730 137 2300 177 7300 217 23000 25718 75 58 236 98 750 138 2360 178 7500 218 23600 25819 77.5 59 243 99 775 139 2430 179 7750 219 24300 25920 80 60 250 100 800 140 2500 180 8000 220 25000 26021 82.5 61 257 101 825 141 2575 181 8250 221 25750 26122 85 62 265 102 850 142 2650 182 8500 222 26500 26223 87.5 63 272 103 875 143 2725 183 8750 223 27250 26324 90 64 280 104 900 144 2800 184 9000 224 28000 26425 92.5 65 290 105 925 145 2900 185 9250 225 29000 26526 95 66 300 106 950 146 3000 186 9500 226 30000 26627 97.5 67 307 107 975 147 3075 187 9750 227 30750 26728 100 68 315 108 1000 148 3150 188 10000 228 31500 26829 103 69 325 109 1030 149 3250 189 10300 229 32500 26930 106 70 335 110 1060 150 3350 190 10600 230 33500 27031 109 71 345 111 1090 151 3450 191 10900 231 34500 27132 112 72 355 112 1120 152 3550 192 11200 232 35500 27233 115 73 365 113 1150 153 3650 193 11500 233 36500 27334 118 74 375 114 1180 154 3750 194 11800 234 37500 27435 121 75 387 115 1210 155 3875 195 12100 235 38750 27536 125 76 400 116 1250 156 4000 196 12500 236 40000 27637 128 77 412 117 1280 157 4125 197 12800 237 41250 27738 133 78 425 118 1325 158 4250 198 13250 238 42500 27839 136 79 437 119 1360 159 4375 199 13600 239 43750 279
