Although best recommended to use 4 same tyres, but its still okay if u running 2 front wheel with same brand and spec tyres (changed same time so the wear and tear was even for both left and right) and the other 2 rear tyres with another brand spec.

Conclusion : front no nit same with rear, but both left and right must be same, in term of brand, spec and change. Dun change just 1 tyre. The grip will be different if both left and right using different and in higher speed might cause u to lose control.
