Question
I have a 1997 Rover 414Si. Somebody is selling me four 195/50R15 its the best size for my car
and THANKS allot

Answer
Khader,

On every vehicle sold in the US, there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size. The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.

BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.

While I can't be sure, I have been told that this placard is also used worldwide. If you would consult the placard on your vehicle, I think THAT is the best size for your car.
