{"product_id":"rtx-st-18x7-15-black-5x115mm-71-5mm","title":"RTX Steel 18x7 +15mm Black","description":"\u003ch2\u003eAbout RTX Wheels\u003c\/h2\u003e\n\u003cp\u003eRTX is a wheel brand distributed by Transamerican Auto Parts and positioned as an entry-level to mid-range aftermarket option for passenger cars, trucks, and SUVs. The brand focuses on delivering affordable steel and alloy wheels designed to meet OE-style fitments as well as light custom applications.\u003c\/p\u003e\u003cp\u003eRTX wheels are recognized for their broad fitment coverage, making them a common choice for replacement and value-oriented upgrades. Finishes typically include machined, painted, and multi-spoke alloy styles suited to everyday driving.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRTX\u003c\/strong\u003e targets budget-conscious consumers who prioritize functional reliability and straightforward aesthetics over premium styling or performance-focused construction.\u003c\/p\u003e\n\u003ch2\u003eAbout the RTX \u003c\/h2\u003e\n\u003cp\u003eThe RTX ST in 18x7 is built around a 5x115mm bolt pattern and a 71.5mm centerbore, making it a precise match for vehicles like the Dodge Charger, Dodge Challenger, and Chrysler 300 — platforms where factory fitment tolerances matter most. The +15mm offset positions the wheel face closer to the fender edge, giving the stance a purposeful, planted look without requiring aggressive modifications.\u003c\/p\u003e\u003cp\u003eFinished in a clean matte black, the RTX ST carries a restrained, understated presence that complements the broad shoulders of a Charger or the formal proportions of a Chrysler 300 without overwhelming the factory design language. This is a wheel that refines the look of the car rather than competing with it.\u003c\/p\u003e\u003cp\u003eWith a load rating of 650 kg (1,433 lbs) per wheel, the ST is engineered to handle daily driving demands with confidence. The 18x7 sizing pairs well with a wide range of OEM-width tire profiles, keeping the overall setup balanced and road-ready.\u003c\/p\u003e\u003cp\u003eAll orders ship free to the contiguous 48 states, and every purchase is backed by TFS Wheels' 100% fitment guarantee. Before ordering, verify your vehicle's hub bore against the 71.5mm centerbore — hub-centric rings may be needed depending on your specific application.
