## Abstract

A vehicle wheel tire having a symmetrical five rib tread construction with adjacent tread ribs comprising the tread separated by circumferential grooves. The intermediate tread grooves have an axial width wider than an axial width of the shoulder grooves and a center rib has an axial width wider than the axial widths of the intermediate ribs and the shoulder ribs. The axial width of the center rib, intermediate ribs, and shoulder ribs are within a prescribed preferred range of a total tread axial width and the axial width of each intermediate groove is within a prescribed preferred range of total tread axial width.

## Claims

### Claim 1

A tire tread comprising a center rib, first and second intermediate ribs on opposite lateral sides of the center rib and separated from the center rib respectively by first and second intermediate circumferential grooves, and first and second shoulder ribs on opposite axially outward sides respectively of the first and second intermediate ribs and separated from respective intermediate ribs by first and second circumferential shoulder grooves; the intermediate grooves each having an axial width wider than an axial width of the shoulder grooves, and the center rib having an axial width wider than a respective axial width of the intermediate ribs and the shoulder ribs, wherein the central rib has an axial width within a range of 18 to 21 percent of the total tread axial width, the axial widths of the intermediate ribs are each within a range of 10 to 15 percent of the total tread axial width, the shoulder ribs have respective axial widths each within a range of 17 to 21 percent of the total tread axial width, the intermediate grooves have respective axial widths each within a range of 4 to 9 percent of the total tread axial width, and the axial widths of the shoulder grooves are each within a range of 2 to 4 percent of the total tread axial width.

### Claim 2 (depends on 1)

The tire tread of claim 1, wherein the axial width of each intermediate groove is within a range of from 4 to 8.5 percent of the total tread axial width.

### Claim 3 (depends on 1)

The tire tread of claim 1, wherein the axial width of each of the intermediate ribs is within a range of from 11 to 14 percent of the total tread axial width.

### Claim 4 (depends on 1)

The tire tread of claim 1, wherein the tread is a symmetric tread with respect to the equatorial plane of the tread.

### Claim 5 (depends on 1)

The tire tread according to claim 1, wherein the axial width of the center rib is within a range of 19.25 to 19.75 percent of a total tread axial width.

### Claim 6 (depends on 5)

The tire tread of claim 5, wherein the axial width of each of the intermediate ribs (18, 20) is within a range of from 12 to 13 percent of the total tread axial width.

### Claim 7 (depends on 6)

The tire tread of claim 6, wherein the axial width of each intermediate groove is within a range of from 6 to 6.5 percent of a total tread axial width.

### Claim 8 (depends on 7)

The tire tread of claim 7, wherein the axial width of each shoulder groove is within a range of 2 to 3.5 percent of a total tread axial width.
