OK, here is a July 2014 update:
My restored 84 Supra has been sitting and running on what was possibly the absolute last set of new Michelin Pilot tires in 225/60HR14. At 10 plus years old, they are aging out and showing spider web cracking in the sidewalls so its time for me to replace them. Doing some research online and talking to a couple of local tire dealers lead to this list:
STOCK SIZE 225/60-14: pretty much limited to the B F Goodrich radial TA, S rated, Cooper used to have their Cobra in that size but it appears to be gone , and reportedly no better than the BFG TA, Cobras were S rated. Yoko Avid ST gone.
STEP UP TO 235/60R14: BFG TA available in this size as is the Cooper Cobra GT, and Mastercraft Avenger, (A Cooper sister brand). There are also a Hercules brand, a Maxxus Marauder brand and a couple of other private label brands like Laramie, Tempra, etc in this size, all S rated.
STEP DOWN TO 215/60R14: If you can live with the slightly smaller size, choices get better: H rated tires are available such as the Riken Raptor, the Geostars mentioned above, and the Nexen CP641 directional radial tire. Other brands, mostly private label, exist in this size such as Federal. And, you can get the BFG radial TA in this size, but why would you want to with 225 and 235 sizes available.
GO TO A MORE COMMON SIZE: According to the rep at Discount Tire, the 205/70R14 tire will work, but its a bit taller and narrower than stock 226/60r14. A tire size comparator is available here:

This will let you compare tire sizes. A few more mainstream tires are available in this size such as the Michelin Defender, as well as Kumho, Falken, Firestone, and Uniroyal options. In case you didn't know, the brands Uniroyal, B F Goodrich and Riken are owned by Michelin. As for me, I am leaning toward the 215/60r14 H rated Riken Raptors. If anyone has any additions or corrections to this list, please jump in here. :thumbsup:
