The standard Toyota alloy wheels for the 90-92 cars are:

Diameter 14" front and rear

Width 6" front and 7" rear

Offset 45mm front and rear

PCD:

114.3mm

Front tyre: 195/60 x 14", 29psi

Rear tyre:

205/60 x 14", 32psi.

The original tyres were Continental, but after poor reviews uni-directional Bridgestone Potenza RE 71s were fitted to the MR2, but now often replaced with the Yokohama A520's.

From 1992 onwards wheels are:

Diameter 15" front and rear

Width 6" front and 7" rear

Offset 45 mm front and rear

PCD:

114.3mm

Front tyre: 195/55 x 15", 29psi

(Some owners prefer a more easily sourced 205/50 x 15" to reduce understeer)

Rear tyre: 225/50 x 15", 33psi.

Original tyres are Yokohama A-022's, and wear rate is high.

Bridgestone S-02's are the usual replacement type.

Tyre wear is most rapid on the inside edges of the front, and outside edges of the rear tyres, if the suspension is correctly aligned.

If non standard alloys are fitted to the car, it is recommended that you keep two size differences between the front and the rear tyres

- for example, using 17" rims 215 width tyres could be fitted to the front and 235 width tyres fitted to the rear.

This helps keep the balance of grip front to rear roughly the same as with the OEM tyres.

hope this points you in the right direction.
