PNEUMATIC TIRE MOUNT METHOD, AND COMBINATION PNEUMATIC TIRE

摘要

Each pneumatic tire (1) disposed on the rear wheel side has a total groove area ratio of 20% or more and 27% or less in ground-contacting width (WT). Each pneumatic tire (1) disposed on the front wheel side and the rear wheel side has a smaller groove area ratio on the vehicle outer side than on the vehicle inner side in the ground-contacting width (WT). The difference in the groove area ratio (calculated in %) is 7 or more and 15 or less. The total groove area ratio is greater on the front wheel side than on the rear wheel side, the difference in the total groove area ratio (calculated in %) being 3 or more and 10 or less. The ratio of an average value of groove widths of all of circumferential grooves (22) on the vehicle inner side to the groove width of a maximum width circumferential groove (22) on the vehicle inner side is greater on the rear wheel side than on the front wheel side, the difference in the circumferential groove (22) ratio (calculated in %) being 1 or more and 10 or less. The ratio of a total groove area of a rug groove (24) on the vehicle inner side and a total groove area of a rug groove (24) on the vehicle outer side is greater on the front wheel side than on the rear wheel side, the difference in the rug groove (24) ratio (calculated in %) being 6 or more and 20 or less.
