Not trying to be a dick or rain on anyones parade but I'm failing to see why this is such an "amazing deal"....
Wheels are 1150 new....Tires are $160 each...TPMS you can get for $50 for a set...mount and balance $40...So all in new you're lookin at $1850...so $150 off for a used set with 10% of the tread gone??? $1500 is fair....$1400 or below is cheap IMO
Wheels $1150
Tires (Nitto 420s 305/40/22) are $200/ea +/-
Sensors - $100 set per eBay ($50/set is rare, if u can find them for that, let me know, I need a few sets)
Mount and Balance -$40??? Runs around $100-200 down here in FL and when I lived in NC
Lugs - $50.00
This is a great deal. Sure, if you wanna bargain shop and try to find some cheap tires and a set of sensors for the low, and have a friend mount and balance them, you can get it for a good price. BUT... not everyone has these connections or the time to shop around.
