Colusa County and the Rural Counties' Environmental Joint Powers Authority are offering free tire disposal every Saturday in March.
For county residents and passenger truck or car tires without rims only, the weekly drop-off is open from 8 a.m.-2 p.m. at the county Road Department, 5714 E St., Williams.
No more than nine tires will be accepted.
For a transportation exemption to carry up to 20 tires or for more information, call Colusa County Public Works at 458-0466.
The effort is funded by a grant from the Department of Resources Recycling and Recovery.
