Tyre specification
Fitment details
- Official page states unladen weight may vary with configuration.
- Official IWT running-gear catalogue maps TA5GHD/TA510G to five-bolt axles and the 16-inch tyre assemblies to the five-bolt P0808S rim; official handbook specifies 5xM14 at 110 Nm.
- Match the fitted tyre and wheel fixing to the listed specification.
- Check the trailer plate and the tyre sidewall before inflating or tightening.
Choose the setting for the confirmed wheel fixing.
Socket size alone does not identify the thread.
Alloy wheels are not covered by these settings.
Tyre pressure placard
Trailer visual reference for the Ifor Williams TA510T 16ft × 4ft H/R tri-axle configuration; equipment and production details may vary.
| Tyre size | kPa | PSI | bar |
|---|---|---|---|
| 175/75R16C | 480 | 69 | 4.8 |
Please ensure the maximum pressure marked on your tyre sidewall is equal to or higher than the pressure listed here.
A tyre of the same size with a lower pressure rating may have been fitted by mistake.
Never exceed the maximum pressure marked on the tyre.
Is your tyre load rating high enough?
Find the load index beside the tyre size. For example, 104 = 900 kg per tyre. For normal trailer wheels, use the first number in 104/102N. The second is for tyres mounted side by side on one hub, not a trailer with two axles. N is the speed symbol.
Open the tyre load rating conversion chart →
Capacity per tyre × number of road tyres = combined tyre capacity. Do not count the spare or jockey wheel.
Example: four tyres rated 104 give 900 × 4 = 3,600 kg, which exceeds a 3,500 kg trailer maximum gross weight by 100 kg. This is a total-capacity comparison only.
Check your tyre capacity
Enter all three values to compare capacity.
Check every axle too: its tyres must support its plated maximum axle weight, and no individual tyre may be overloaded. This calculator assumes all tyres have the same load index and are mounted singly. It does not confirm fitment or set tyre pressure. Keep the trailer manufacturer’s required load and speed ratings, use the specified cold pressure and check the actual loaded axle weights.
Cold tyre pressure
69 PSI / 4.8 bar / 480 kPa
A separate unloaded or fully laden pressure has not been confirmed for this entry.
Wheel nut / bolt torque
Use the setting only for the wheel and fixing specification described above.
