So I'm guessing its about $1100 and some change to change the tags to 365 over 315? For the extra safety that's pretty cheap insurance for me.
i think that is right. the cost of the wheels. then you get back whatever you sell the old ones for.

Andrew, I think you have not included the cost of the tires. The cost of tires and wheel is something north of $2,000.
I was calculating the cost over replacing them with 315.
