HD03

RTX HD03: a clean monoblock daily wheel

The RTX HD03 is a monoblock wheel built for everyday cars and crossovers that want a tidy, no-fuss look. Its multi-spoke face keeps the profile understated in dark Gloss Black, so it works on commuters and light utility builds without shouting for attention. It sits within the wider RTX lineup as one of the brand's straightforward monoblock options.

Sizes and fitments stocked

The HD03 comes in 16, 17 and 18 inch diameters, in widths of 7, 7.5 and 8 inches, all at a +40 offset. Bolt patterns cover 5x114.3 and 5x120, which suits a broad range of Japanese and Korean sedans, hatches and small crossovers, plus a number of European fitments on 5x120.

Concrete examples: the 16x7 +40 in 5x114.3 is the compact end, the 17x7.5 +40 in 5x114.3 is the middle-of-the-road daily pick, and the 18x8 +40 in 5x114.3 fills the arches on larger cars. For 5x120 builds, the 18x8 +40 in 5x120 covers that pattern. You can also browse the full RTX 5x114.3 range if you want to compare other RTX faces on the same bolt pattern.

Finish

The HD03 is offered in Gloss Black — a deep, easy-to-keep look that pairs with most paint colors. If you want to see other tones across the brand, the black RTX wheels, silver RTX wheels and gray RTX wheels pages group them by color.

Price and who it suits

The HD03 runs from $181 to $238 depending on size, which puts it firmly in value-daily territory. It suits owners who want a clean, durable-looking wheel for a commuter or family car without stretching the budget. If the HD03 face isn't quite your taste, the RTX Spark takes a sportier spoke, the RTX Crush goes bolder, the RTX Trek leans toward light truck and crossover duty, the RTX Hida offers a different mesh look, and the RTX Force is another everyday alternative.
