Can I fit a cheaper tyre to a BYD Dolphin Surf?

What changes on this car

Sold in China as the Seagull, the Dolphin Surf is the smallest BYD on UK roads, yet both of its sizes are XL: 175/65 R15 88V and 185/55 R16 87V.

Here the smaller wheel carries slightly more. The 15 inch tyre is rated to 560 kg and the 16 inch to 545 kg. The 115 kW version is listed only on 16 inch wheels, while the 65 kW car appears on both.

No tyres listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 175/65 R15. Match or exceed every figure in the table above and you cannot go far wrong.
