There is no single correct pressure for every 265/70R19.5 tire. The required cold inflation pressure depends on the tire’s exact service description, the measured axle load, whether it is fitted single or dual, and the manufacturer’s load-and-inflation data.
This size is a particularly good example because commercial truck and trailer products can share the same dimensions while carrying different load indexes, speed symbols and maximum inflation pressures. Several manufacturers use these two rating groups. Michelin, Continental and Hankook offer 140/138 truck specifications, while Continental, Hankook and Pirelli list higher-capacity 143/141 trailer products. The exact pressure still depends on the individual manufacturer’s table.

265/70R19.5 pressure and rating comparison
| Example tire | Service description | Application | Maximum single load | Maximum dual load | Published maximum pressure |
|---|---|---|---|---|---|
| Michelin X Multi Z / XDE2+ | Load Range G | Truck all-position or drive | 2,500 kg per tire | 2,360 kg per tire | 112 PSI |
| Bridgestone metric reference | Load Range G | Truck, buses and trailers subject to product approval | 2,500 kg per tire | 2,360 kg per tire | 110 PSI |
| Sailun SAR1 | 140/138M, 16 PR | Regional all-position truck | 2,500 kg per tire | 2,360 kg per tire | 112 PSI (775 kPa) |
| Sailun catalog 18 PR variant | 143/141J | Application depends on the exact pattern | 2,725 kg per tire | 2,575 kg per tire | 131 PSI (900 kPa) in the referenced catalog |
| Continental North American LRH reference | Load Range H at 81 mph | Truck | 2,500 kg per tire | 2,360 kg per tire | 115 PSI |
| Continental European Hybrid HS3 / HD3 | 140/138M | Truck steer/all-position or drive | 2,500 kg per tire | 2,360 kg per tire | 116 PSI in the referenced metric table |
| Hankook AH35 / DH35 | 140/138M | Truck all-position or drive | 2,500 kg per tire | 2,360 kg per tire | 110 PSI |
| Continental Hybrid HT3 | 143/141J or K, market/product generation dependent | Trailer | 2,725 kg per tire | 2,575 kg per tire | 123 PSI for the referenced 143/141 table |
| Hankook Smart Flex TH31 | 143/141J | Trailer | 2,725 kg per tire | 2,575 kg per tire | 123 PSI |
| Pirelli ST:01 FRT | 143/141J | Trailer | 2,725 kg per tire | 2,575 kg per tire | Use the matching Pirelli technical table |
The comparison shows why tire size alone is not enough. Michelin, Bridgestone, Continental, Hankook and Sailun truck products can share the same nominal 140/138 or equivalent capacity while publishing different pressure steps or product limits. Continental, Hankook and Pirelli also offer 143/141 trailer specifications. A shared load index does not authorize copying one brand’s PSI limit into another brand’s tire.
Bridgestone 265/70R19.5 Load Range G table
The Bridgestone metric table supplied for normal highway service identifies 265/70R19.5 as Load Range G at its maximum listed condition. The pressure in this table is the minimum cold pressure for the corresponding per-tire load.
| Cold pressure | Single load per tire | Dual load per tire |
|---|---|---|
| 80 PSI | 1,800 kg | 1,700 kg |
| 85 PSI | 1,900 kg | 1,780 kg |
| 90 PSI | 1,970 kg | 1,860 kg |
| 95 PSI | 2,060 kg | 1,950 kg |
| 100 PSI | 2,200 kg | 2,000 kg |
| 105 PSI | 2,340 kg | 2,170 kg |
| 110 PSI | 2,500 kg (G) | 2,360 kg (G) |
Sailun 265/70R19.5 pressure references
The Sailun load table spans two pages. The first visible portion lists the following low-pressure values for 265/70R19.5. These are per-tire loads, with separate single and dual rows.
| Cold pressure | Single load per tire | Dual load per tire |
|---|---|---|
| 65 PSI | 1,550 kg | 1,450 kg |
| 70 PSI | 1,660 kg | 1,560 kg |
| 75 PSI | 1,740 kg | 1,640 kg |
| 80 PSI | 1,800 kg | 1,700 kg |
Current Sailun product data adds an important product-level distinction. The 265/70R19.5 SAR1 140/138M 16 PR regional all-position tire is rated for 2,500 kg single and 2,360 kg dual at 112 PSI (775 kPa). A separate 18 PR 143/141J catalog specification is rated for 2,725 kg single and 2,575 kg dual at 900 kPa (131 PSI). These two Sailun specifications must not share one pressure setting.
Michelin Load Range G load and inflation table
The Michelin truck databook lists the following axle capacities for 265/70R19.5 Load Range G. These figures are axle loads: a single-tire axle uses two tires, while a dual-tire axle uses four tires.

What 143/141J means on the TH31 trailer tire
On the Hankook Smart Flex TH31, 143 is the load index for single fitment and 141 is the load index for dual fitment. Those indexes correspond to 2,725 kg and 2,575 kg per tire respectively. Four tires in dual fitment therefore have a nominal combined capacity of 10,300 kg at the product’s published maximum condition.
The letter J is the speed symbol, corresponding to 100 km/h under the applicable rating conditions. By comparison, M corresponds to 130 km/h. The higher 143/141 load index does not mean the tire also has a higher speed rating. The TH31 configuration is a trailer-specific option designed around a different load-and-speed requirement.
Continental 140/138M and 143/141 trailer data
Continental publishes more than one regional reference for this size. The North American table shown for 265/70R19.5 Load Range H at 81 mph reaches 2,500 kg single and 2,360 kg dual per tire at 115 PSI. Continental’s European technical guide lists truck patterns such as the Conti Hybrid HS3 and HD3 at 140/138M, using metric pressure steps that reach the same nominal load at 8.0 bar (116 PSI). These are separate published tables, not a reason to round one value into the other.
| Cold pressure | Single axle, LI 140 | Dual axle, LI 138 | Single axle, LI 143 | Dual axle, LI 141 |
|---|---|---|---|---|
| 109 PSI | 4,745 kg | 8,960 kg | 4,930 kg | 9,315 kg |
| 116 PSI | 5,000 kg | 9,440 kg | 5,190 kg | 9,810 kg |
| 123 PSI | Not listed above LI 140 maximum | Not listed above LI 138 maximum | 5,450 kg | 10,300 kg |
Where Pirelli fits in the comparison
Pirelli lists the ST:01 in 265/70R19.5 FRT 143/141J. FRT identifies a free-rolling trailer application, while J is the 100 km/h speed symbol. Its load indexes place it in the same nominal 2,725 kg single and 2,575 kg dual capacity group as the referenced Continental and Hankook trailer products.
However, the article does not transfer Hankook or Continental PSI data to the Pirelli tire. Before setting pressure on a Pirelli ST:01, use the current Pirelli technical table for the exact product and market. The common 143/141J marking establishes load and speed categories, not permission to substitute another manufacturer’s operating recommendation.
How to select the correct cold PSI
- Read the complete sidewall marking, including load index, speed symbol and load range where shown.
- Confirm the tire’s approved position and application. Do not treat a trailer tire as interchangeable with a steer or drive product merely because the size matches.
- Weigh the vehicle in normal operating condition. Individual axle-end weights are preferable; otherwise use an accurate axle weight.
- For a single-tire axle, divide axle load by two. For a dual-tire axle, divide it by four.
- Use the matching manufacturer’s single or dual column and select a published cold pressure that supports at least the measured load.
- Stay within the tire, wheel and vehicle manufacturer’s limits. The lowest component rating controls.
For help identifying all the markings before using a table, see our truck tire sidewall markings guide. You can also compare the approach with the published Goodyear truck tire pressure chart.
Technical caveats for fleets and trailers
- Maximum pressure is not a universal recommendation. It identifies the maximum condition for the stated product rating.
- Do not mix single and dual values. Dual ratings account for the different operating conditions of paired tires.
- Keep dual tires matched. Significant differences in inflation, diameter or tread depth can cause one tire to carry more than its share.
- Check pressure cold. Do not bleed pressure from a hot tire simply because its operating pressure has risen.
- Verify the rim rating. The wheel must be approved for the required load and pressure.
- Account for imbalance. If only total axle weight is available, an appropriate fleet policy should address side-to-side variation without exceeding component limits.
Pressure control works best as a repeatable fleet process rather than a one-time setting. Our guide to pressure management in truck fleets explains how inspections, calibrated gauges and maintenance records support tire performance.

Bottom line
A 265/70R19.5 tire should not be assigned a pressure from size alone. Michelin, Bridgestone, Continental, Hankook and Sailun truck products can share a nominal 2,500/2,360 kg load capacity but use manufacturer-specific pressure data. Continental, Hankook and Pirelli also list higher-capacity 143/141 trailer products with different speed and application requirements. Match the exact product, application and measured load to the correct manufacturer table.
There is no single PSI for every 265/70R19.5 tire. Use the exact tire manufacturer’s load-and-inflation table, the measured axle load, and the correct single or dual column.
110 PSI is the published maximum for certain Hankook 140/138M truck products, but it is not a universal operating recommendation. Michelin Load Range G and Hankook trailer specifications use different published limits.
140/138 and 143/141 are single and dual load indexes. M and J are speed symbols. The 143/141J TH31 trailer specification carries a higher nominal load but has a lower speed symbol than 140/138M truck products.
Do not substitute tires based only on size or higher load index. Confirm approved axle position, application, speed requirement, rim rating and vehicle manufacturer requirements before any replacement.
No. Dual fitment must use the manufacturer’s dual rating. Divide the measured axle load by four and verify that each tire is supported at the selected cold pressure.
