4WD and off-road tyres are grouped into four broad terrain categories. Each is a trade-off between on-road manners (noise, wear, fuel use) and off-road grip — there's no single "best" option, only the one that best matches how much time you actually spend off the bitumen.
H/T — Highway Terrain
Closest to a standard passenger tyre tread pattern. Quiet, smooth, and long-wearing on sealed roads, with minimal off-road capability. Best for a 4WD or SUV that mostly stays on the highway.
A/T — All-Terrain
A chunkier tread pattern that balances on-road comfort with real off-road grip on dirt, gravel and light mud. Noisier and slightly higher wear than H/T, but the most popular choice for vehicles that see a genuine mix of on-road and off-road driving.
M/T — Mud Terrain
Aggressive, deep, widely spaced tread blocks designed to bite into mud, sand and rock and self-clean as you drive. The best off-road grip of the four, but noticeably noisier, thirstier and faster-wearing on the highway. Suited to serious off-roaders and regular low-range use.
R/T — Rugged/Hybrid Terrain
Sits between A/T and M/T: a more aggressive tread than an A/T with better on-road manners than an M/T. A good "do-it-all" compromise if neither of the other two categories quite fits your use.
A simple rule of thumb
The more time you spend off-road, the further along the H/T → A/T → R/T → M/T scale you'll want to sit — and the more road noise and fuel use you'll trade for it. If you're not sure which category your current tyres fall into, check the tread pattern name printed on the sidewall alongside the size code (see our guide on reading a tyre sidewall if you need a refresher on the rest of that code).
Whichever terrain type suits you, make sure any replacement matches or exceeds your vehicle's placard load index and speed rating — the terrain category never overrides that requirement.
