2024 INEOS Trucks Tire Fitment Guide

2024 INEOS Trucks vehicles use two tire sizes: 255/70R18 and 265/70R17, and both apply to the Grenadier. The 255/70R18 mounts on an 18-inch wheel, while the 265/70R17 mounts on a 17-inch wheel. For the 265/70R17, the compatible rim width range runs from 7.0 to 9.0 inches. These are both radial sizes, but they are not interchangeable because the wheel diameters differ.

That means the first fitment check on a 2024 INEOS Trucks Grenadier is the actual wheel diameter already on the truck. Once that is confirmed, the correct tire path becomes much clearer. If your truck is on 17-inch wheels, you can then compare the available 265/70R17 product versions by load rating and intended use. If it is on 18-inch wheels, stay within the 255/70R18 fitment path instead of trying to cross over by approximate overall size.

On a 2024 INEOS Trucks Grenadier, 255/70R18 is a metric radial size. The 255 is the nominal section width in millimeters, 70 is the aspect ratio, the R indicates radial construction, and 18 is the wheel diameter in inches. It is a modern sizing system rather than an older numeric or alphanumeric classic-car code, so it gives you width, profile, and rim diameter in one line.

For a buyer, the important part is that the final number controls wheel compatibility. A 2024 INEOS Trucks Grenadier with 18-inch wheels needs an 18-inch tire size, even if another size appears close in width or sidewall height. Metric sizing also makes it easier to compare modern tire categories, especially when you are deciding between road-focused and all-terrain products within the same basic fitment family.

On a 2024 INEOS Trucks Grenadier, 265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series aspect ratio, and a 17-inch rim diameter. The R confirms radial construction. In the available BFGoodrich products for this size, both versions carry an S speed rating, which corresponds to a 112 mph ceiling, but they differ in load index and maximum load capacity.

That matters because two tires can share the same basic size while serving somewhat different load needs. On a 2024 INEOS Trucks Grenadier, reading the full size and service description is just as important as matching the 17-inch diameter. If you use the truck for gear-heavy travel, towing-related load demands, or sustained rough-surface work, reviewing the exact load version within 265/70R17 becomes part of a correct tire choice.

A 2024 INEOS Trucks Grenadier does not use 255/70R18 and 265/70R17 as interchangeable alternatives on the same wheel. The deciding factor is wheel diameter: 255/70R18 belongs on 18-inch wheels, and 265/70R17 belongs on 17-inch wheels. Both are radial fitments, so this is not a classic bias-ply-versus-radial choice. It is a wheel-package question first and a tire-product question second.

Start by physically verifying the wheel diameter already on your 2024 INEOS Trucks Grenadier or checking the wheel marking. After that, compare products within the correct size rather than comparing across sizes. If your truck runs 17-inch wheels, you can evaluate the BFGoodrich 265/70R17 choices by load version and intended use. If it runs 18-inch wheels, stay in the 255/70R18 category and avoid assuming close measurements make a cross-size swap acceptable.

For 2024 INEOS Trucks applications covered here, the 265/70R17 is available with an RWL sidewall, meaning raised white letters. That look fits the all-terrain character of the BFGoodrich KO2 and gives the tire a more traditional truck-oriented appearance. No sidewall-style variation is established here for the 255/70R18 fitment, so the main confirmed style detail centers on the 17-inch Grenadier option.

Sidewall appearance matters more on a vehicle like the 2024 INEOS Trucks Grenadier than it would on a generic modern crossover, because the truck’s design leans heavily into utility and heritage cues. Some owners prefer the visual presence of raised white letters, while others may mount them inward when the tire design allows. If appearance is part of your decision, check the exact sidewall treatment on the specific product before committing to a set.

BFGoodrich is the confirmed brand available here for the 2024 INEOS Trucks Grenadier in 265/70R17 form. The available products are both BFG All-Terrain T/A KO2 tires, offered in the same basic size with different load indexes and maximum load capacities. That keeps the brand choice simple in this fitment while still giving buyers an important specification choice within the size itself.

For a 2024 INEOS Trucks owner, that means the comparison is less about changing brands and more about matching the right version of the tire to the truck’s use. A Grenadier used lightly on-road may not need the same load specification as one carrying equipment for overland travel or regular cargo duty. When the brand family is narrow, service description, load rating, and wheel compatibility become the points that deserve the closest attention.

For 2024 INEOS Trucks fitments covered here, the 265/70R17 uses a 17-inch rim and fits a rim-width range of 7.0 to 9.0 inches. That range is broad enough to cover typical modern off-road-oriented wheel widths in this diameter. The 255/70R18 is an 18-inch fitment, so wheel diameter is clear, but a width range is not established here for that size.

Rim width matters because it affects sidewall shape, tread profile, and how the tire sits on the wheel. Even when the diameter is correct on a 2024 INEOS Trucks Grenadier, a wheel that falls outside the approved width range can change the tire’s behavior and appearance. If you are working with aftermarket wheels, verify both width and diameter against the exact tire you intend to use rather than assuming any 17-inch or 18-inch wheel will be acceptable.

The available 2024 INEOS Trucks products here are modern radial tires, and no inner-tube requirement is established for the 265/70R17 BFGoodrich options. That is very different from antique and early postwar fitments where tube-type construction was common. For the Grenadier’s modern metric sizes, tube use should never be assumed simply because the vehicle has an old-school look or off-road mission.

The practical step is to confirm the wheel design and the exact tire specifications before installation. On a 2024 INEOS Trucks Grenadier, the wheel itself plays a major role in whether tubeless service is appropriate. If you are replacing only tires and keeping factory-style modern wheels, the answer is usually straightforward. If you are changing to specialty wheels, verify compatibility with the wheel maker and the tire manufacturer before mounting.

A 2024 INEOS Trucks Grenadier should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Keep the truck off wet ground and avoid long exposure to standing moisture. Even modern radials age faster when they sit under poor environmental conditions, especially if they are left dirty or underinflated for extended periods.

If the truck will sit for weeks or months, move it periodically so the tires are not parked on the same contact patch the entire time. Some owners also use tire cradles or stands for long-term storage, particularly on heavier 4x4s. A 2024 INEOS Trucks Grenadier used for seasonal trips or occasional adventure travel benefits from storage habits that reduce flat-spotting, sidewall weathering, and avoidable aging between drives.

Tires on a 2024 INEOS Trucks Grenadier should be evaluated by age as much as by tread depth. A good rule is to begin paying close attention once tires reach about five to seven years of age and to treat around ten years as the point where replacement deserves serious consideration, regardless of mileage. The DOT date code on the tire sidewall tells you when each tire was manufactured.

That approach matters because many specialty-use vehicles, including a 2024 INEOS Trucks Grenadier, may accumulate miles more slowly than a daily driver. A tire can still look usable while rubber compounds have hardened or begun to degrade internally. Regular age checks help you avoid relying on tread alone. If the truck sees expedition use, highway travel, or heavy loading, age-related caution becomes even more important than on a lightly used local runabout.

Tires on a 2024 INEOS Trucks Grenadier should be checked before every drive and given a more thorough inspection before any extended outing. Look for cuts, punctures, bulges, cracking, uneven wear, and any sign of impact damage from trail use or curb contact. Pressure should also be checked regularly, not just visually, because a modern radial can be underinflated without appearing obviously flat at a glance.

A deeper inspection every few months is a smart habit, especially if your 2024 INEOS Trucks sees mixed on-road and off-road use. Pay attention to tread wear across the full width, inspect the sidewalls after rough-surface travel, and make sure the spare is in equal condition. A vehicle built for adventure often invites longer trips into places where tire problems are harder to solve, so early inspection is part of basic trip preparation.

The confirmed 2024 INEOS Trucks Grenadier products in 265/70R17 carry an S speed rating, which corresponds to a 112 mph maximum rating under proper conditions. That is well above normal U.S. highway speeds, so the practical safety question is usually less about the published speed ceiling and more about inflation, load, wear condition, and overall vehicle setup. On a modern 4x4 like the Grenadier, suspension loading and cargo weight can matter as much as the rating letter itself.

Safe highway use in a 2024 INEOS Trucks also depends on matching the tire to the wheel, using the correct load version, and keeping the truck mechanically sound. An aggressive all-terrain tire can be entirely appropriate for highway travel when it is in good condition and used within its rating. Before a long interstate run, confirm pressures cold, inspect for damage, and make sure the chosen tire aligns with how heavily the truck will actually be loaded.

For 2024 INEOS Trucks fitments here, the available 265/70R17 tires include one version rated at 2,470 pounds at 50 psi and another rated at 3,195 pounds at 80 psi. Those figures are maximum load-and-pressure ratings for the tire versions themselves, not a universal operating pressure for every Grenadier. Inflation should follow the vehicle manufacturer’s recommendation for the truck’s configuration and use, while also staying within the tire maker’s limits.

That means you should not transfer a pressure figure from one 2024 INEOS Trucks tire version to another just because the size is the same. Load index, intended use, and wheel setup all influence the right working pressure. Start with the vehicle placard or owner’s manual, then compare that recommendation with the exact tire’s service description and pressure capacity. Recheck pressures cold and adjust for real-world loading rather than guessing from sidewall numbers alone.

Before a longer trip in a 2024 INEOS Trucks Grenadier, inspect every tire for cracking, cuts, punctures, bulges, uneven wear, and any embedded debris from off-road use. Check cold inflation pressure, verify tread depth is consistent across the axle, and make sure the spare is usable and properly inflated. A quick look at the wheel rims for damage is worthwhile too, especially if the truck has seen rocky trails or hard curb contact.

Tires are only one part of the pre-drive routine, but they deserve extra attention because they carry the entire load and directly affect handling and braking. On a 2024 INEOS Trucks used for travel beyond paved roads, it is smart to match the inspection to the trip plan. The farther you are going, and the heavier the cargo, the more important it becomes to confirm the correct tire size, load version, pressure, and the condition of the spare before departure.
