I am looking to get an 18" spare tire.

But here are my issues..

-anything less than an 18" wheel/rim will NOT fit
-anything with more than 4.5" backspacing (and plus 42mm offset) will NOT fit
-bolt pattern must be a 6 x 115mm(NOT 6x4.5")
-final Overall Diameter must be around 26.6"
-tire width must be less than 225width in order to fit in spare tire well

-tire would need to be in the 145/80/18 size range(that is 27.1", and is the dodge challenger spare size, but impossible to find to buy)

I was looking online and I could most likely have a custom 18" steel rim made, like an 18x4(maybe up to 6"), with the proper bolt pattern and 2" backspacing(variable depending on final width of rim) with 0 offset. But i still cant find a 18 temporary tire to buy...


BTW stock tire size is 245/45/18. when mounted on the 18x8.5" stock wheel, it will NOT fit flush in the spare well.
So if i spent the 200+ for a stock rim, id still then need to have it narrowed at least 2"...
