The tires should be 185/55r15. Or 185/60r14 crappy us installers will always tell you they are hard to find etc, but in reality more cars use that size than they ever admit (the 14at least) the 15 switch toa 195/50r15 it's cheaper, better options etc

As for running if the piston was damaged enough to not run correctly, then it wouldn't run at all, or at least not for long.


Things to check: coil, wires plugs, compression, timing marks. If those all are ok post back.
