The Castle Rock ST225/75R15 Radial Tire w/ 15" Liger Aluminum Wheel - 6 on 5-1/2 - LR D - Black # LH29FR that you referenced does not come with a center cap and lug nuts so you'd need the # LHCS108-SI60C for the center cap and then for lug nuts the part # LHLR103 for a stainless lug nut. Stainless lug nuts are great because they don't corrode which means they won't swell up and get difficult to fit a socket on. view full answer...
