Apollo Apterra HL 205/65 R15 99S

Going for a single new tyre is not recommended as it affects the stability, handling and braking performance. There is no match between three used tyres with minimal groove and one new tyre with dense tread depth. Either go for two new tyres and install them at front, use two best-conditioned ones (from existing) at rear and remaining one tyre as spare. Go for a similar brand as the current if possible, if not, pick any pattern. Or, you can also change all four tyres if they have covered 30,000-40,000 or max 50,000 kilometres.

The MRF ZVT, Apollo Altrust, and the CEAT CZAR H/T are good options for the Mahindra Scorpio S3.

Based on your use type, the suggested tyre for your car is the Apollo Amazer 3G Maxx as its asymmetric tread pattern provides effective grip and the robust sidewalls provide for enhanced cornering capabilities.
