Just reuse it. Save yourself several hundred dollars.
I am very opinionated about this. Burn the stock tires to the ground. at the track, of course. there are much better tires for alot less money. all depends on what you want from a tire. The Bs are rated well but they were a bit jumpy with steering response and without a good road feel for me. Felt they were always over pressured. And man did they spin easy, great for smoke shows or just showing off I guess.I might suggest you consider a bit wider wheel to accommodate a 225 or more down the road. A 7.5 or 8" wheel will be ok with stock tire till you replace tires.
quite honestly, selling stock tires just isn't worth it. it's a lot of trouble, and not many people want to buy used tires. (i know i don't) if i were you, i would just use them up and worry about buying new ones afterwards.
EDIT: i know what they retail for, but very few people buy the stockers again because it's just not worth 200+ a pop for tires that wear out in like 10k-15k miles when you could have better tires for less...=/

The 215/45/18s work fine on an 18x8. However, I HIGHLY suggest you stay away from kerbs. I found out the hard way.
