Your 93.5 OEM sizes (15x7 and 16x8) are really limited in matched vendor sets. BFG T/A (H rated tires) may be the only choice. Even then, the availability is difficult. If you're willing to do BFG TA front and Pirelli/ Michelin in back, it may be possible but the handling may not optimal. 15 and 16 inch tires are simply too old/small of a market, hence the limited choices.
I started off with 15" BFG TA all around. Ok tire but nothing special. Just bought 17" S4s wheels that allow better choices of tires.
For 17" I'm going with a Dunlop Direzza DZ101
Upgrading wheels on Esprit is quite an adventure - search the Esprit forum for 'wheel' and there are a few threads on tire/wheel fitment on the older cars.
