If I went to buy a second hand Nismo and it was sitting on Falkens I would be thinking that if the previous owner can't afford decent tyres then has he also skimped on proper servicing????
Also, the difference between Falkens and a premium tyre is night and day.
Do you really want to be constantly on edge with budget tyres or completely relaxed with a premium tyre?
If you go the budget route remember and inform your insurance.
Might be a plan to review your budget.
