For your consideration, here we have a vintage Gulf tire insert.  Measures 15 1/2 in diameter.  This is a painted metal tire insert for Gulf Tires, advertising all sizes, grades and prices!  This one appears to be NOS, as there are no signs of ever being mounted inside a tire and still retaining the paper instruction label!  In overall excellent condition, with some minor scratching and edge wear as shown, with excellent colors that have a slight reflection to it.  A great insert!  Displays beautifully.  An excellent addition to any collection.  Please ask any and all questions you may have, and don't forget to check out our other items!  Shipped via USPS and insured.  Thanks for looking.
