Van tyres are built to carry heavy loads, so they use a stronger construction than car tyres and follow the same legal limits. The key is the load rating: a van tyre is marked with a higher load index and usually a "C" (for commercial) or "Reinforced" on the sidewall, and fitting a tyre below the rating your van needs is both unsafe and illegal. Get the rating and pressures right and a van tyre is straightforward.
What makes a van tyre different
A van spends its life near its weight limit, so its tyres need stiffer sidewalls and stronger casings to carry the load without overheating. That's the main difference from a car tyre of the same size. The trade-off is a slightly firmer ride, which is exactly what you want under a loaded vehicle. Many vans also do high mileage, so durability and cost per mile matter as much as outright grip.
Reading the C and load markings
On a van tyre you'll often see a size like 215/65 R16C, where the C means commercial. You may also see two load indices (for single and twin-wheel axles). The load index is the number before the speed-rating letter, and it must meet or exceed what your van requires. If in doubt, the door-pillar placard and handbook give the exact figures, including the higher pressures a loaded van needs.
The law for van tyres
The legal minimum tread of 1.6mm across the central three-quarters applies to vans up to 3,500kg, the same as cars, and the penalties are the same: up to £2,500 and 3 points per tyre under the tyre safety law (GOV.UK). DVSA also carries out roadside checks on vans, so a defective tyre on a commercial vehicle is a real liability. Fitting the wrong size or an under-rated tyre can fail the MOT too.
Avoiding van tyre failures
Overloading and under-inflation are common causes of van tyre failure, because both make the tyre flex and overheat. Always use the laden pressure figure when the van is loaded, don't exceed the axle weights, and check pressures more often than you would on a car. If you run several vans, a simple check routine pays for itself, see our fleet tyre guide.
Van tyre pressures: laden, unladen and why they're so high
Use the laden figure whenever there is anything in the back, and expect the rear pressures on a van to be far higher than on a car. The placard in the door shut usually gives two sets of figures, and on many vans the rear laden pressure is well above 50 psi. That is not a misprint; it is what stops a loaded tyre flexing and overheating. If the placard or your gauge uses bar, our tyre pressure converter switches between bar and psi.
The reason the rear figure is so high is simple: the load sits over or behind the rear axle, so the rear tyres carry most of the payload. Running them at a car-like 32 psi while loaded is a common cause of van tyre failure, because the sidewall flexes on every rotation, builds heat, and eventually the casing lets go.
A few practical rules:
- Check pressures cold, at least weekly, and before any long or heavily loaded trip. Some forecourt airlines struggle at van pressures, so a decent gauge and a compressor that goes to 80 psi are worth owning.
- If the van runs empty most of the week and loaded on some days, set the laden pressure and leave it. A slightly firm ride empty is far safer than a soft tyre loaded.
- Where the van has tyre pressure monitoring, treat it as a last warning, not a routine check. It typically alerts only once a tyre is well below the set figure.
Twin load indices and twin-wheel axles
A marking like 109/107 means the tyre can carry the first figure when fitted as a single and the second figure per tyre when fitted as a pair on a twin-wheel axle. Most panel vans use singles, so the first number is the one to match, but larger vans, chassis cabs and many motorhomes run twin rears, and then the second figure applies.
| Load index | Maximum load per tyre | Typical use |
|---|---|---|
| 100 | 800 kg | Car-derived small vans |
| 104 | 900 kg | Compact vans |
| 107 | 975 kg | Mid-size vans (twin figure) |
| 109 | 1,030 kg | Mid-size vans (single figure) |
| 113 | 1,150 kg | Large panel vans |
| 116 | 1,250 kg | Large vans and motorhomes |
| 121 | 1,450 kg | 3.5-tonne chassis cabs, heavy motorhomes |
Multiply the per-tyre figure by the number of tyres on the axle and compare it with the axle weight on the van's plate; the tyres must carry at least that. On twin-wheel axles, the inner tyre is easy to forget. It needs the same pressure and the same inspection as the outer one, and a valve extender makes checking it far less of a chore.
MOT classes and DVSA roadside checks for vans
Vans up to 3,000kg design gross weight take the same class 4 MOT as a car; vans between 3,000kg and 3,500kg take a class 7 test, and the tyre checks are the same in both. The tester looks at tread depth, cuts, bulges, exposed cord, and whether the tyres on each axle are of the same size and construction. A tyre that is clearly unsuitable for the vehicle, including one below the required load rating, is a failure item. Details of the test are on GOV.UK.
Between MOTs, vans are far more likely than cars to be stopped for a DVSA roadside check, particularly around ports, industrial estates and motorway check sites. Officers check tyres and can also weigh the van. A defective tyre can bring an immediate prohibition, meaning the van goes nowhere until it is fixed, on top of the fine of up to £2,500 and 3 points per tyre described in the tyre law guidance. Overloading is a separate offence with its own penalties.
The practical lesson is that on a working van, a tyre problem costs a day's work as well as the tyre. Our guide to MOT tyre checks covers what the inspectors look for.
A weekly van tyre check that takes five minutes
Many van tyre problems show warning signs before the tyre fails, so a short routine check catches a lot of them. Do it on a flat surface with the van cold, and turn the steering to full lock on each side so the inner sidewalls of the front tyres are visible.
| Check | How | Act if |
|---|---|---|
| Pressures | Gauge on all tyres, cold, against the placard | Any tyre more than a few psi down, or one repeatedly losing air |
| Tread depth | 20p test across the full width, inner, centre and outer | Below 3mm anywhere, or one edge much lower than the rest |
| Sidewalls | Look and run a hand around both sides | Cuts, bulges, cracking or exposed cord |
| Tread face | Look for embedded screws, nails, stones and glass | Anything embedded, even if the tyre is holding air |
| Valves | Caps present, stems not cracked or leaning | Missing caps, perished or bent stems |
| Age | Date code on the sidewall | Tyres approaching six years old, especially on vans that sit for weeks |
| Spare or kit | Spare pressure, or sealant kit in date | Flat spare or an expired kit |
Uneven wear across an axle is worth acting on quickly, because on a loaded van the worn edge goes from thin to illegal fast.

We fit van and commercial tyres at your depot, at home or at a safe place off the road, from our one base at Brent Cross, NW2, including out-of-hours when the diary allows, so a van isn't off the road during working time. Tell us the registration and load and we can supply the correct C-rated tyre, subject to availability in your size.
