The 2007 Isuzu Trucks i-370 sits in the compact pickup market of the mid-2000s, sharing the practical, body-on-frame character that made these trucks useful as everyday drivers and light-duty work pickups. For tire selection, the key detail is that the i-370 uses radial tires on 15-inch rims, but the correct size changes with drivetrain: 225/75R15 for the LS 4x2 and 265/75R15 for the LS 4x4. That makes this page less about choosing between bias-ply and radial construction and more about confirming the exact sub-model, then comparing the available tire styles, especially within the 225/75R15 size where several whitewall-oriented options appear.
Which Tire Size Is Right for The 2007 Isuzu Trucks i-370
The 2007 Isuzu Trucks i-370 uses two primary tire sizes, and the right one depends on the exact sub-model. Both are radial tires for 15-inch rims, but the LS 4x2 uses 225/75R15 while the LS 4x4 uses 265/75R15. Before choosing a tire, confirm whether the truck is a 4x2 or 4x4, then match the size to the wheel setup and the style of tire you want.
In 265/75R15, the 265 is the nominal section width in millimeters, 75 is the aspect ratio, R means radial construction, and 15 identifies the wheel diameter in inches. For the 2007 Isuzu Trucks i-370, this size applies to the LS 4x4 and points to a larger radial fitment than the 4x2 truck uses. The practical focus with this size is confirming the 4x4 configuration and making sure the truck still has the correct 15-inch wheel setup. It is the right size to investigate when the goal is preserving the proper fitment relationship for the 4x4 sub-model rather than adapting a tire from the 4x2 version.
Tire fitment for the 2007 Isuzu Trucks i-370 changes by sub-model, so identifying the truck as an LS 4x2 or LS 4x4 is the first step. Both use radial construction on 15-inch rims, but the tire size itself is different, which makes sub-model confirmation more important than brand or sidewall choice at the start.

2007 Isuzu Trucks i-370 LS 4x2
The 2007 Isuzu Trucks i-370 LS 4x2 uses the smaller of the two primary tire sizes and stays with radial construction on a 15-inch rim. That means the main decision is choosing among the available 225/75R15 product styles, including whitewall variations and different tire series, rather than sorting through multiple primary fitments.
The 2007 Isuzu Trucks i-370 LS 4x4 uses a different primary tire size than the 4x2 truck, while still remaining a radial tire on a 15-inch rim. For this sub-model, correct selection starts with keeping the 265/75R15 fitment tied to the 4x4 setup and confirming the wheel package before comparing tire choices.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2007 Isuzu Trucks i-370?
The 2007 Isuzu Trucks i-370 uses two primary tire sizes, depending on sub-model. The LS 4x2 uses 225/75R15, while the LS 4x4 uses 265/75R15. Both are radial tires and both fit 15-inch rims, so the size choice is tied to drivetrain configuration rather than a change in construction type.
The practical step is confirming whether the truck is a 4x2 or 4x4 before choosing tires. A 15-inch rim alone does not make the two sizes interchangeable, and a truck with aftermarket wheels or a changed suspension should be checked carefully for wheel width, clearance, and overall fitment before a new set is selected.
What size rim does a 2007 Isuzu Trucks i-370 use?
The 2007 Isuzu Trucks i-370 uses a 15-inch rim with both of its primary tire sizes. The 225/75R15 fitment for the LS 4x2 and the 265/75R15 fitment for the LS 4x4 both share that same rim diameter, even though the tire widths and overall dimensions differ.
Rim diameter is only one part of the fitment picture, so it helps to verify wheel width as well before choosing a tire. That matters most when the truck no longer has its original wheel setup, because a 15-inch rim can still vary in width enough to affect how a particular tire mounts and presents on the vehicle.
Do all 2007 Isuzu Trucks i-370 sub-models use the same tire size?
No, the 2007 Isuzu Trucks i-370 sub-models do not all use the same tire size. The LS 4x2 uses 225/75R15, while the LS 4x4 uses 265/75R15. Both use radial construction and both mount on 15-inch rims, but the actual tire size changes with the sub-model.
That difference matters because the first buying decision is identifying the truck correctly, not simply matching the rim diameter. A tire chosen only by wheel size can still be wrong for the vehicle configuration, especially if the truck has had wheel changes, ride-height changes, or other modifications that affect width and clearance.
Choosing the Right Tire
What should I consider when choosing a 225/75R15 tire for a 2007 Isuzu Trucks i-370?
For a 2007 Isuzu Trucks i-370 LS 4x2, start by confirming that 225/75R15 is the correct size and that the truck still uses a 15-inch wheel within the tire’s rim-width range. Available tires in this size are all radial, so the choice becomes one of brand, series, sidewall appearance, load figure, and wheel compatibility.
Appearance is a major part of the decision in this size because options include narrow whitewall and wide whitewall styles from several brands. It also helps to compare each tire’s rim-width specification and maximum load at its stated pressure so the selected tire suits both the wheel and the way the truck will actually be used.
What sidewall styles are available for 2007 Isuzu Trucks i-370 tires?
Within the 225/75R15 fitment used on the 2007 Isuzu Trucks i-370 LS 4x2, available sidewall styles include narrow whitewall and wide whitewall. That gives the truck a broader appearance range than a plain blackwall-only selection, especially for owners who want a more distinctive or restoration-inspired presentation.
Sidewall style should be chosen after the correct size and wheel fitment are confirmed, not before. A wide whitewall creates a very different visual effect from a narrow whitewall, so the right choice depends on whether the truck is being kept mostly stock in appearance, given a custom look, or simply fitted with a tire that complements its finish.
What brands offer tires for the 2007 Isuzu Trucks i-370?
For the 225/75R15 size used on the 2007 Isuzu Trucks i-370 LS 4x2, available brands include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar. Those choices appear across several radial tire series and whitewall styles, giving the buyer more than one path depending on the truck’s intended look and use.
Brand selection is best handled as part of a broader comparison rather than a shortcut. Once the correct size is confirmed, compare the tire series, sidewall treatment, rim-width range, weight, and load specification so the final choice matches both the truck’s wheel setup and the type of presentation you want on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Isuzu Trucks i-370?
A period-style 2007 Isuzu Trucks i-370 still needs the correct size for the exact sub-model first: 225/75R15 for the LS 4x2 or 265/75R15 for the LS 4x4. On the 4x2 truck, the available 225/75R15 radial choices include several whitewall-oriented options that can create a more customized or nostalgic presentation.
The right appearance choice depends on whether the goal is subtle or more visually pronounced. A narrow whitewall gives a cleaner, lighter accent, while a wide whitewall makes a stronger styling statement. When exact originality matters, compare the selected look with period photos, dealership material, or marque-specific references before settling on a tire style.
Which sidewall style suits a period-style 2007 Isuzu Trucks i-370?
For a period-style 2007 Isuzu Trucks i-370 LS 4x2, the available 225/75R15 sidewall choices include narrow whitewall and wide whitewall. A narrow whitewall usually keeps the truck’s appearance more restrained, while a wide whitewall has a stronger custom flavor and changes the visual balance of the wheel and tire package more noticeably.
The best choice depends on the truck’s finish, wheel design, and the overall look being pursued. Sidewall style should complement the vehicle rather than overpower it, and it still needs to be selected within the correct tire size and wheel specification. Appearance matters, but fitment should remain the first decision every time.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Isuzu Trucks i-370?
Yes, modifications can affect tire fitment on a 2007 Isuzu Trucks i-370 even when the tire size appears correct on paper. Aftermarket wheels, changes in wheel width, altered offset, suspension lifts or lowering, and body changes can all influence how a 225/75R15 or 265/75R15 tire actually sits and clears.
A modified truck should be checked at full steering lock and through normal suspension movement before new tires are put into service. Clearance at the fenders, inner wheelhouse, and suspension components matters just as much as the printed size, especially on a 4x4 where wheel and ride-height changes can shift the fitment picture significantly.
What should I inspect before driving a 2007 Isuzu Trucks i-370 on new tires?
Before driving a 2007 Isuzu Trucks i-370 on new tires, inspect the wheels for damage, confirm the correct 15-inch rim setup, and make sure the tire size matches the truck’s sub-model. It also helps to check valve stems, lug hardware, and basic suspension condition so the new tires are mounted on a sound platform.
Once the tires are installed, verify inflation pressure, look for any rubbing during turns, and recheck that the truck tracks and steers normally. A short local drive followed by another visual inspection is a smart final step, particularly on a vehicle that may have sat for a while or no longer wears its original wheel package.
How often should tires on a 2007 Isuzu Trucks i-370 be inspected?
Tires on a 2007 Isuzu Trucks i-370 should be inspected regularly, not just when tread looks low. Air pressure, tread wear, sidewall condition, cuts, bulges, and signs of aging all deserve routine attention, especially if the truck is driven infrequently or spends long periods parked between uses.
A quick visual check before driving and a more thorough inspection at regular service intervals can catch problems before they become larger ones. Uneven wear can also point to alignment, suspension, or wheel issues, so inspection is not only about the tire itself. It is one of the simplest ways to protect fitment, ride quality, and road readiness.
