Firefighters tackled a large blaze at a farm at Haresfield on Sunday night.
Residents were being being warned to keep their windows closed because of the smoke coming from the site in Colethrop Lane.
Several hundred tyres went up in flames but Gloucestershire Fire and Rescue said the blaze was under control last night.
People living within a three to five mile radius are being advised to close windows as a precaution.
