i bought the wheel insurance for 5 years or whatever. says they give you wheels and tires for 5 years is it anything like chevy's tires for life you just give them your tire size and they put them in stock until you need them or do they just give you the same size tire as stock?

i have 2 nails in my rears :-\ wanna get some yokos but not sure if this warranty is gonna tie me down
