A 7.00R16 tire should not be assigned a pressure from size alone. Verified commercial truck examples use a G/14PR construction with a 118/114 service description, but the final speed symbol and intended service can differ by tread pattern.
The manufacturer figures in this guide are maximum-load endpoints. They do not establish a proportional relationship between load and pressure, and they must not be used to invent lower PSI settings.
7.00R16 verified maximum-load reference
| Fitment | Load index | Maximum load per tire | Axle total at that rating | Published cold pressure |
|---|---|---|---|---|
| Single | 118 | 1,320 kg / 2,910 lb | 2,640 kg for two tires | 770 kPa / 112 psi |
| Dual | 114 | 1,180 kg / 2,600 lb | 4,720 kg for four tires | 770 kPa / 112 psi |
These figures are published for verified ZC Rubber 7.00R16 G/14PR truck products. The axle totals are simple multiplication of the stated per-tire maximum and assume balanced loading. They are not vehicle axle ratings and do not override rim, axle or legal limits.
118/114J versus 118/114L
Two verified patterns use the same 1,320 kg single and 1,180 kg dual ratings at 112 psi, but one carries an J speed symbol and another an L symbol. J corresponds to 100 km/h, while L corresponds to 120 km/h. The matching load numbers do not make the products interchangeable at the higher speed.
Speed capability depends on the approved product construction and operating conditions. Never change a J-rated tire into an L-rated tire on paper because the size, ply rating and load indexes look identical.

Tube-type installation
Verified heavy commercial examples are tube type. A TT tire requires a compatible tube, flap, rim and valve. The assembly should be inspected for trapped or folded tubes, flap damage, corrosion, incorrect valve position and unsuitable rim components.
Do not assume that every 7.00R16 tire uses the same rim or construction. Confirm the complete product data and sidewall. The truck tire sidewall guide explains PR, load index, speed symbol and TT/TL markings.
How to determine the correct cold pressure
- Weigh the normally loaded vehicle, preferably at each wheel position.
- Confirm whether the axle uses single or dual fitment.
- Identify the exact tire brand, pattern, 14PR/load range, service description and construction.
- Request the manufacturer’s complete load-and-inflation table when only a maximum endpoint is available.
- Select a published cold-pressure row that supports the measured load and remains within every component limit.
Do not divide the 112 psi maximum by the percentage of maximum load. Tire load capacity is not a simple linear PSI calculation. Do not borrow a pressure row from 7.50R16 or another apparently similar size.
Operational checks for dual assemblies
The dual rating is 140 kg lower per tire than the single rating in this verified specification. Use the dual index and dual table for a four-tire axle. Keep paired tires matched in approved specification, remaining diameter and cold pressure, with correct spacing between sidewalls.
Measure cold pressure before driving and investigate repeat leakage. Do not bleed a hot tire back to its cold setting. A consistent fleet pressure-management routine is especially important for inner dual tires that are difficult to inspect.

Technical caveats
- 112 psi is the cited maximum-load pressure, not a recommendation for every vehicle.
- Use load index 114, not 118, for dual fitment.
- Keep the J or L speed symbol attached to its exact product rating.
- The lowest tire, tube, rim, valve, axle or vehicle limit governs.
- No lower PSI has been inferred from the maximum figures.
Frequently asked questions
There is no universal PSI. Use measured load and the approved table for the exact tire, 14PR specification, service description and fitment.
No. It is the maximum-load pressure for the verified G/14PR products cited here. The operating pressure must still be selected from load and exact manufacturer data.
The cited products are rated for 1,320 kg single and 1,180 kg per tire in dual fitment at their 112 psi maximum-load endpoint.
Their cited load indexes are the same, but J corresponds to 100 km/h and L to 120 km/h. The product with the lower speed symbol must not be operated as the higher-speed version.
No. Use load index 114 and the manufacturer’s dual data. The single index 118 does not apply to a paired dual assembly.
