The \u003cstrong\u003eU101 Indy\u003c\/strong\u003e pulls directly from vintage American racing wheel geometry: wide-set spokes, a slightly dished face given the aggressive offset, and a machined barrel that lets the polished surfaces catch light at multiple angles as the wheel rotates. On white, silver, or two-tone truck bodies the contrast is clean and intentional. It also works on flat-black or dark-green rigs where you want one bright element doing the visual work. Lowered mini-trucks, bagged SUVs, and traditional custom builds are the natural home for this diameter and width combination.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDiameter x Width\u003c\/th\u003e\n\u003ctd\u003e15\" x 10\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBolt Pattern\u003c\/th\u003e\n\u003ctd\u003e6x139.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOffset\u003c\/th\u003e\n\u003ctd\u003eET-50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBackspacing\u003c\/th\u003e\n\u003ctd\u003e3.53\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHub Bore\u003c\/th\u003e\n\u003ctd\u003e108.00mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLoad Rating\u003c\/th\u003e\n\u003ctd\u003e1900 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eCast\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminum alloy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003ePOLISHED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd\u003eU10115008335\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis wheel runs the 6x139.7 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET-50mm offset is typical for stock-height fitments; leveled and lifted trucks may want different offset\/backspacing combinations to clear larger tires. A hub-centric ring is recommended when the wheel hub bore is larger than the vehicle hub.\u003c\/p\u003e\n\u003ch3\u003eAbout the POLISHED Finish\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eUS Mag\u003c\/strong\u003e has been producing classic American-style cast wheels since the 1960s and has maintained that retro-performance identity without drifting into trend chasing. The \u003cstrong\u003e1PC\u003c\/strong\u003e designation means the wheel is a single-piece cast construction — straightforward to balance, repair if scuffed, and source replacement hardware for. They occupy a solid mid-market position: not a budget import, not a boutique forged price point either.\u003c\/p\u003e\n\u003ch3\u003eAbout US Mag 1PC\u003c\/h3\u003e\u003cp\u003eUS Mag 1PC produces wheels distributed nationally through trusted vendor channels.

That offset is aggressive and will place the wheel face outside the stock fender line on most applications, so confirm your wheel well clearance and whether you need a fender flare or rolled lip before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo lug nuts come included?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo, lug nuts are sold separately. Because polished wheels use a specific seat angle and shank length to protect the finish around the lug pocket, it is worth confirming the correct seat type — typically a conical or mag-style seat — before purchasing hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I finance a set?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes.
