Our car needed tires, as the ones it came wearing were simply aged-out. Back in the day, finding sporty tires for a car like our 1991 Nissan 240SX was easy: You simply ordered a 225/50R15, a suitable upgrade from the original 195/60R15 size.
Guess what? That size isn’t so popular any more. Sure, you can find full-on, DOT-approved race tires in that size, but the current extreme and ultra-high performance models skip that size since it has simply fallen from favor. More on this 240SX on the Grassroots Motorsports website.
