A total groove width Sg1 of main grooves provided on the vehicle outside is less than a total groove width Sg2 of main grooves provided on the vehicle inside. An outer shoulder main groove 4A has the narrowest groove width among respective main grooves 3, 4. An outside shoulder land part 6A is provided with an outside shoulder rib 10 by provision of an outside shoulder sub groove 8 positioned 3 to 12 mm away from the outer shoulder main groove 4A toward the vehicle outside. An inside middle land part 5B is provided with an inside middle rib 12 by provision of an inside middle sub groove 9 positioned 3 to 12 mm away from an inner shoulder main groove 4B toward the vehicle outside.SELECTED DRAWING: Figure 1 |
