The Gunner 5 is for 5 lug vehicles. The Gunner 6 is for 6 lug vehicles and the Gunner 8 is for 8 lug vehicles. In the 18x8.5 6-114.3 +25 size, the Chrome Gunner 6 has been discontinued and is no longer available. We do have the Anthracite Machined finish available however the 18x8.5 +25 size will not clear the Frontier brake calipers. All the 18" wheels linked below are guaranteed to fit your application stock. We do mount and balance every wheel and tire pacakge we sell for FREE so give us a call at 1.888.459.4080 and anyone of our agents would be happy to help you select the best tire for your needs.So going by the link you provided I'm guessing you can't get the Gunner 5 in chrome in an 18 with the 6 lug pattern?
Thanks for the help Mike!
