INEOS Trucks Grenadier Tires

INEOS Trucks Grenadier uses two tire sizes across the 2024, 2025, and 2026 model years: 255/70R18 and 265/70R17. The 255/70R18 size is for 18-inch wheels, while 265/70R17 is for 17-inch wheels. Both are radial metric sizes, but they are not the same fitment because the rim diameters differ.

The practical takeaway is that year alone does not identify the correct tire for an INEOS Trucks Grenadier. You need to confirm the wheel diameter on the actual truck, then match the tire size to that wheel. Once the size is confirmed, check the load rating on the sidewall or vehicle placard so the replacement tire suits how the Grenadier is equipped and used.

A 2024 INEOS Trucks Grenadier has two tire sizes listed because the model was offered with two different wheel diameters in the same year. One fitment uses 265/70R17 on 17-inch wheels, and the other uses 255/70R18 on 18-inch wheels. That is a wheel-fitment split, not a change from one production year to another.

The important step is to inspect the truck rather than assume one size by model year. Wheel diameter is the deciding factor, and the tire size must match it exactly. If the truck has been modified, compare the current wheel marking and tire sidewall to the intended specification before replacing anything, especially if the vehicle sees both on-road and off-road use.

INEOS Trucks Grenadier uses two rim diameters in this range: 17 inches and 18 inches. The 265/70R17 fitment uses a 17-inch rim, and the 255/70R18 fitment uses an 18-inch rim. Both rim diameters appear across the full 2024 to 2026 span rather than being tied to separate early and late production periods.

That means the right tire starts with the actual wheel on the truck, not just the badge or registration year. A 17-inch tire will not fit an 18-inch wheel, and an 18-inch tire will not fit a 17-inch wheel. Checking the molded tire size on the current sidewall and the wheel itself is the fastest way to avoid an expensive mismatch.

To confirm the correct tire size for a 2025 INEOS Trucks Grenadier, start with the wheel diameter and current tire sidewall. The two listed sizes for that year are 255/70R18 and 265/70R17, and each corresponds to a different wheel size. For the available 265/70R17 products, the rim width range is 7.0 to 9.0 inches, which helps confirm wheel compatibility once the diameter is known.

After verifying the wheel size, check the service description and intended use of the truck. The available 265/70R17 products include both 112S and 121S load versions, so carrying capacity matters as much as size. For a Grenadier used for cargo, accessories, or tougher service, matching the load requirement is just as important as matching the diameter.

The available INEOS Trucks Grenadier products in 265/70R17 use an RWL sidewall style. RWL means raised white letters, a look commonly associated with all-terrain tires and utility-focused 4x4s. No alternate sidewall style appears in the current product set for that size.

Sidewall style matters mostly for appearance unless you are trying to match a specific visual theme. An RWL tire gives an INEOS Trucks Grenadier a more traditional off-road look, especially if the truck is being kept in a purposeful expedition style rather than a more understated black-sidewall appearance. If appearance is a priority, confirm the sidewall style before finalizing the exact tire.

The current INEOS Trucks Grenadier product set includes BFGoodrich. The listed products are both BFG All-Terrain T/A KO2 tires in 265/70R17, offered in two different load versions. That means brand choice is narrow in the present range even though the load specification varies within the same tire line.

For a buyer, that makes specification matching more important than simply choosing by name. With an INEOS Trucks Grenadier, the difference between the available products is not brand family but carrying capacity and service rating. Once the wheel diameter is confirmed, compare the sidewall marking and the intended duty of the truck so the selected tire aligns with how the vehicle will actually be used.

A INEOS Trucks Grenadier should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings. Tires last better when they are protected from constant UV exposure and when inflation is kept at the appropriate pressure for storage and normal load. If the Grenadier sits for long periods, moving it occasionally helps reduce flat spotting.

Collectors and occasional-use owners should also keep the truck clean underneath and avoid parking for months on wet concrete or soil. A modern radial all-terrain tire is more durable than older collector tire types, but age and environmental stress still matter. Good storage habits preserve ride quality, sidewall condition, and overall usefulness when the Grenadier returns to regular service.

Tires on a INEOS Trucks Grenadier should be inspected regularly, with a quick visual check before driving and a more thorough inspection at routine service intervals. Look for cuts, embedded debris, sidewall damage, irregular tread wear, and pressure loss. On an all-terrain vehicle like the Grenadier, trail use and heavy loading make inspections even more important.

Frequent inspection helps catch problems before they become roadside failures or handling issues. If the truck alternates between pavement and rough terrain, examine the shoulders and sidewalls carefully, since those areas take a lot of abuse. Keeping an eye on wear patterns can also reveal alignment, suspension, or inflation issues before a replacement set is needed.

Tires on a INEOS Trucks Grenadier should be replaced when age, damage, cracking, puncture history, or structural concerns make them questionable, even if tread depth still looks acceptable. Collector-style low-mileage use can hide tire aging because the rubber may deteriorate long before the tread wears out. A tire that appears full-depth can still be too old or compromised for dependable use.

The safest approach is to judge tires by condition, age, and service history rather than tread alone. If an INEOS Trucks Grenadier has sat for long periods, has seen harsh off-road impacts, or shows sidewall cracking, have the tires evaluated and replace them if there is any doubt. That is especially important on a heavy utility 4x4 where tire loads can rise quickly.

The listed INEOS Trucks Grenadier products are modern radial all-terrain tires intended for road use when they are correctly sized, properly mounted, and matched to the truck's wheel diameter and load needs. The available 265/70R17 versions include different load capacities, so safety depends on selecting the right specification rather than treating every tire in that size as equivalent.

Before road use, confirm that the tire size, load index, and speed rating align with how the Grenadier is equipped. A utility-focused 4x4 can carry accessories, cargo, and passengers that materially change tire demand. Proper inflation, even wear, and a close look for trail damage are all part of keeping the truck roadworthy.

Before driving a INEOS Trucks Grenadier, check tire pressure, visible tread and sidewall condition, and make sure all four tires match the intended wheel diameter and specification. On the available 265/70R17 options, also confirm that the load version fitted is appropriate for the truck. Uneven wear, cuts, bulges, or a recent loss of pressure should be addressed before driving.

That pre-drive check matters even more if the Grenadier has been used off-road or has been sitting. A brief inspection can catch a puncture, a sidewall bruise, or an underinflated tire before it affects handling and braking. On a heavy 4x4, small tire issues can become major problems once the truck is loaded or driven at speed.

The appropriate speed for a INEOS Trucks Grenadier depends on the speed rating of the exact tire fitted, along with load, inflation, and operating conditions. The available 265/70R17 products carry an S speed rating, but that does not override the need for sensible speeds on a tall, off-road-oriented utility vehicle. Terrain, cargo, temperature, and tire condition all affect the margin of safety.

In practice, a Grenadier should be driven within the tire's rating and within the real limits of the vehicle's setup and use. Long highway runs with extra weight, rough trails, and sustained heat all place more stress on the tires. Matching speed to conditions, and not just to the posted limit, is a big part of preserving tire life and maintaining stable handling.
