Spare tire cover for Jeep

 Somewhere I saw a photo of a Jeep Wrangler with a crocheted cover on the spare tire.  It inspired me to try to create one of my own.  It's going quite well, as you can see.  I'm using the Hemlock Ring Blanket pattern available on Ravelry.  I'm using bulky yarn and four 36" US11 circular knitting needles in the same way you would use double point needles.

I'm crocheting granny squares for the tread part of the tire.  They are being made with same bulky yarn and size N crochet hook.  Looks like I will need 11 of them.

My tire = Radius of 15, circumference 92”, width of tire treads 8 1/2”
