PURPOSE:To produce the regenerated tire which has the abrasion resistance equal to or more than a new tire, the braking and drawing properties on snow and excellent appearance by setting the length in width direction of a tire in at least the tread width of a new tire in a precured tread. CONSTITUTION:The tread width L1 of a precured tread 16 is set in the range of at least the tread width L of a new tire 15 and of at most 1.2 times of the tread width of the new tire. In the precured tread 16, the thickness of the end in width direction of the tire is gradually reduced almost into a tapered shape inside in the radious direction of the tire as a wing 18. In said wing 18, the wing length M shown by the straight line from the end 16B in width direction of the tire of the tread part 16A of the precured tread 16 to the end 16D in width direction of the precured tread is set in at most 75% to the straight line N from the end 16B in width direction of the precured tread 16 to the point Q of the maximum width of a holder tire, and said length M is set so that it is at least two times of tread-thickness T at the end 16B in width direction of the tire of the precured tread 16. The pattern 20 of uneven battless part is provided in the battless part 19 of the precured tread. |
