275 = tread width in millimetres · 35 = sidewall height as a percentage of that width · R19 = radial construction on a 19-inch wheel. Two sizes with the same overall diameter are speedometer-compatible, that is the whole game in staggering.

Fitment hardware
Dialing in how a setup sits on this platform? Hub-centric wheel spacers fine-tune effective offset and caliper clearance one axle at a time, aftermarket wheels usually need lug nuts in the matching seat and thread, and aggressive fitments bring adjustable control arms into play for camber. Code KSPAF takes 5% off at KSP Performance. Start with the measurement math in the wheel spacer sizing guide.
