I think your only option may be the M/T Sportsman, but it is a bias ply. Part number 255669. Summit has them in stock.
I was looking for a radial a while back and M/T told me they had no idea when or if they'd be producing the 27-28" tall radial fronts again. They also had an ET Street front radial (3851) that's 27" tall, now it's part number 250736. Summit shows one of those in stock.
I got lucky and found a new set of the M/T SR radials (6678) for sale in the classifieds here and got them.
