Hey Mr. Como, (first name perry?)

Anyway, since your new to the Mid-engined Reardrive 2 group(?) I think it important to point out a RWD item.

Since your car has the transmission in the rear it is somewhat important that you remember at all times that the rear tires must be matched in size. Sure, you can put on any sized tire during a rear tire failure and drive under 45 mph to the nearest facility to help you out.

But remember your mis-matched rear tire size will stress the differential in a way that will accelerate wear, will produce extra heat in the transmission case and produce possible premature differential failure.(Spider gears and differential bearing failure)

All mr2 owners should keep this in mind during x-country adventure emergencies?

Personally I always carry a full sized spare in the front trunk that matches my rear tire sizes which I can always use in the front for flat tire emergencies since the front tires do not have this complication.

Happy Motoring Ya'll...
