The TR6 steel wheels are 5.5. However, the wires might be 4.5" or
maybe 5". 5.5" wheels will fit 205/70-15's - I just put on Yoko A378's
in that size, and they work great. Size difference is ~1% smaller than
stock - close enough not to matter. They look good on it too. If you want
serious performance tires, you could go to Yoko AVS Intermediates (AVSi)
in 205/65-15 or even 215/65-15. 215 is pushing past the "correct" size for
the rims, but only by 1/4". You might have rubbing with 215's. I haven't
noticed any with 205's.

4A's had narrower rims, at least in steel wheel.
