Bakkie tyres in South Africa: the right size for every model, and what the all-terrain premium buys

Tyres are the one part of a bakkie that every owner replaces, usually more than once, and the one where the most money gets wasted on the wrong choice. This guide covers the sizes the major models came with and the upgrades people actually fit. It also looks at what an all-terrain tyre is really worth over a highway tyre, for the driving you do.

One rule before any table: the placard on the driver’s door pillar wins. Manufacturers change sizes between trims and between model years. The table below shows what is common. It is not a substitute for reading the sticker on the bakkie in front of you.

Standard sizes by model

The “C” in 205R16C means a commercial-rated tyre with a stronger sidewall and higher load index. On a workhorse Hilux, or any bakkie that regularly carries a full load, keep the C rating when you replace. A passenger-rated tyre in the same size is not up to the job.

Load and speed ratings

Every tyre carries a load index and a speed rating after the size, for example 265/65R17 112T. The load index (112 is 1,120 kg per tyre) must meet or exceed what the manufacturer specifies, and on a bakkie that carries loads or tows it is not optional. The speed rating (T is 190 km/h, H is 210) matters less on a bakkie, but fitting below the placard rating can affect your insurance.

Where owners get caught is on a 4x4 upgrade. A lot of aftermarket all-terrains in 265/65R17 are light-truck (LT) tyres, with a higher load rating and a stiffer sidewall. That is good for a working vehicle and bad for ride comfort on an empty double cab. Know which one you are buying.

Highway, all-terrain, mud: what they are for

Highway terrain (H/T). What most bakkies leave the factory on. Quiet, long-wearing, good in the wet on tar, fine on graded gravel. The right tyre for a bakkie that lives on the road.

All-terrain (A/T). A more open tread, a tougher carcass, usually a higher load rating. Better on gravel, sand and rock, more puncture-resistant, noisier and heavier. The default upgrade on any bakkie that goes to the farm, the bush or the coast on dirt.

Mud terrain (M/T). Very aggressive tread for mud and rock. Loud, short-lived on tar, poor in the wet on tar. For a vehicle that spends most of its time off-road and very little on the N1.

The honest version: most South African bakkies on A/Ts never leave tar, and their owners pay the premium, the noise and the fuel penalty for a look. If the bakkie genuinely does gravel every week, or one bad puncture on a farm road would cost you a day, the A/T is worth it. If it does the N3 and the school run, the H/T is the better tyre and the cheaper one.

What the premium actually is

Prices move with the rand and the brand. As a rough guide, in the common 265/65R17 size in September 2026:

Budget brands sit well under those numbers and are fine on a work vehicle that does not tow or carry heavy. On a double cab that tows a caravan at 120 km/h with the family in it, buy the tyre from a manufacturer whose name you recognise.

A highway tyre on a bakkie typically lasts 50,000 to 70,000 km. An all-terrain lasts a little less. Both last less again if the bakkie is heavy, tows, or the alignment is out. On a financed bakkie that is a set of tyres roughly every four years, which belongs in the running-cost budget the finance guide describes.

Plus-sizing: going bigger

The common upgrades and what they involve:

One size up in profile (265/65R17 to 265/70R17, or 255/65R17 to 265/70R17). Adds roughly 25 mm to the tyre’s diameter. It usually fits a standard bakkie without changes, gives a slightly softer ride and a little more ground clearance, and puts the speedometer out by about 3 percent. The most common upgrade on a Hilux or Ranger and generally the sensible one.

A 33-inch tyre (285/70R17 or 285/75R16). The Raptor’s size on a standard Ranger or Hilux. Needs a lift of 40 to 50 mm at least, often some trimming of the wheel arch liner, sometimes a wheel offset change. The gearing gets taller, which blunts acceleration and hurts towing, the speedometer reads about 8% low, and the fuel consumption goes up. Insurers want to know, the manufacturer’s warranty on drivetrain parts may not survive it, and roadworthy rules on lift height apply.

35-inch and above. Purpose-built vehicles only. The Isuzu AT35 is engineered for it from the factory; a standard bakkie is not.

Whatever size you fit, fit it to all four and keep the spare matched. A 4x4 with a different rolling diameter on one axle will damage the transfer case in low range.

Checking tyres on a used bakkie

Tyres are one of the quickest reads on how a used bakkie was treated. Four matching tyres from a recognised brand with even wear suggest an owner who maintained things. Four different budget tyres suggest a fleet that bought whatever was cheapest that month. Uneven wear across a tyre, feathering on the edges, or one side worn faster than the other means the alignment is out. On a bakkie, that often means something is bent underneath. Cracked sidewalls on a low-mileage vehicle mean it stood in the sun for years. The ex-fleet buying guide has the rest of the inspection.
