I have a relatively New Flawless (No rips/tears) Spare Tire Cover that I just bought for $69.99 from AllThingsJeep.com. I upgraded tires so it does not fit. It covers the larger size rims/tires like the Sahara wheels and tires.
X-Large:33" X 12.5" or any 32-33" diameter tire, including 255 75 R17; LT255/70R18 tires. This is the right size for most 2007-2010 Jeep Wrangler Sport, Wrangler Sahara and Rubicon Models, both two and four doors.
I will let it go for $55 including USPS Priority Mail shipping
