It is surprising to me how few selections there are for a wide tire in a 27"+ diameter. I searched high and low for a 28" diameter tire that was about 12" wide. The only choices you have are a drag radial which is not exactly what I had in mind. I even contacted BFG to inquire about tires in that size (and I received no help ) and apparently the size I did end up with (285-40-18 = 27" x 11.2") has been discontinued. Don't 60's & 70's muscle cars need a taller wide tire?
