A first land region is defined between a first main groove and a second main groove extending in a tyre circumferential direction. The first land region is provided with a first oblique groove and a second oblique groove. The first oblique groove extends obliquely with respect to a tyre axial direction from the first main groove to have an end portion terminating within the first land region. The second oblique groove extends obliquely with respect to the tyre axial direction from the second main groove to intersect with a middle groove portion of the first oblique groove and terminate there.
