The 2007 Chevrolet Trucks Suburban 2500 sits in the heavy-duty full-size SUV category, built for buyers who wanted the cabin space of a Suburban with the stronger work-oriented character of a 2500-series chassis. That matters when choosing tires, because this model uses two different radial fitments depending on trim: 245/75R16 or 275/55R20. LS and LT models stay with the 16-inch setup, while LTZ models move to a 20-inch package. The key decision is confirming the exact sub-model and wheel diameter first, then choosing a tire that suits the vehicle's load demands, appearance, and intended road use.
Which Tire Size Is Right for The 2007 Chevrolet Trucks Suburban 2500
The 2007 Chevrolet Trucks Suburban 2500 uses two primary tire sizes, and the correct choice depends on sub-model and wheel diameter. LS and LT models use 245/75R16 on a 16-inch rim, while LTZ models use 275/55R20 on a 20-inch rim. Before comparing tires, the first step is confirming which trim and wheel package the vehicle actually has, especially if wheels may have been changed over the years.
245/75R16 is a metric radial size where 245 identifies the section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 16 is the rim diameter in inches. On the 2007 Chevrolet Trucks Suburban 2500, this size is used on LS and LT models and suits the vehicle's heavy-duty SUV role. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is the right place to focus if the vehicle retains its 16-inch wheel setup and is expected to balance utility use with period-appropriate stance.
275/55R20 is a metric radial size with a 275-millimeter section width, a 55-series profile, radial construction, and a 20-inch rim diameter. On the 2007 Chevrolet Trucks Suburban 2500, this size applies to LTZ models, making it distinct from the 16-inch fitment used on other trims. The lower-profile 20-inch format changes the fitment conversation because wheel diameter becomes the first checkpoint before any tire selection begins. This size should be evaluated against the actual wheel package on the vehicle, particularly if appearance upgrades or aftermarket wheel changes are part of its history.
2007 Chevrolet Trucks Suburban 2500 Sub-Model Tires
Tire fitment on the 2007 Chevrolet Trucks Suburban 2500 is trim-dependent rather than universal across the range. Checking whether the vehicle is an LS, LT, or LTZ matters because the tire size and rim diameter change with the sub-model.

2007 Chevrolet Trucks Suburban 2500 LS
The 2007 Chevrolet Trucks Suburban 2500 LS uses the 245/75R16 radial fitment. That keeps tire selection centered on the 16-inch wheel package and makes it important to confirm wheel size before comparing sidewall style, load capacity, or tread character.
The 2007 Chevrolet Trucks Suburban 2500 LT also uses the 245/75R16 radial size. Buyers with this trim should focus on selecting the right tire within that 16-inch fitment, especially if the vehicle is used for heavier hauling, towing support, or general road use.
The 2007 Chevrolet Trucks Suburban 2500 LTZ uses the 275/55R20 radial fitment rather than the 16-inch setup used on LS and LT models. Tire selection starts with confirming that the vehicle still has its 20-inch wheel package and enough clearance for the size being considered.
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.
Best 2007 Chevrolet Trucks Suburban 2500 Tires for Sale
Available product choices for the 2007 Chevrolet Trucks Suburban 2500 currently center on the 245/75R16 fitment, including a BFGoodrich All-Terrain T/A KO2 with radial construction, raised white letter sidewalls, and rim-width compatibility that can be compared against the vehicle's 16-inch wheel setup.
Owners of a 2007 Chevrolet Trucks Suburban 2500 usually need to sort out trim-specific tire size, 16-inch versus 20-inch wheel fitment, radial tire selection, and the practical checks that matter before putting a heavy-duty SUV back on the road.
Tire Size & Fitment
What tire size fits a 2007 Chevrolet Trucks Suburban 2500?
The 2007 Chevrolet Trucks Suburban 2500 uses two tire sizes depending on trim level. LS and LT models use 245/75R16 radial tires, while LTZ models use 275/55R20 radial tires. Both are primary fitments for this model year, but they are not interchangeable choices across the full Suburban 2500 lineup.
The practical first step is confirming the exact sub-model and the wheel diameter currently on the vehicle. A Suburban that has had wheel changes over time may no longer match its original trim-based setup, so the tire should be matched to the actual wheel size, load needs, and available clearance before making a final selection.
What size rim does a 2007 Chevrolet Trucks Suburban 2500 use?
Rim size depends on the trim. The 245/75R16 fitment uses a 16-inch rim, and the 275/55R20 fitment uses a 20-inch rim. On this Suburban 2500, LS and LT models are tied to the 16-inch setup, while LTZ models use the 20-inch arrangement.
Wheel diameter should be verified before shopping for tires because the difference between 16-inch and 20-inch packages changes the entire fitment path. It also helps to confirm wheel width and whether the vehicle still has its original-style wheels, since aftermarket wheel swaps can affect tire choice, sidewall shape, and clearance.
Do all 2007 Chevrolet Trucks Suburban 2500 sub-models use the same tire size?
No. The 2007 Chevrolet Trucks Suburban 2500 LS and LT use 245/75R16, while the LTZ uses 275/55R20. That means the model line does not share one universal tire size, even though all of the primary fitments are radial tires.
This matters because buying by model name alone can lead to the wrong tire. Sub-model confirmation is especially important on vehicles that have changed hands several times or have had appearance upgrades, since a wheel swap can blur the original trim-based fitment and make direct measurement of the wheel a smart second check.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2007 Chevrolet Trucks Suburban 2500?
Start with the basics: the vehicle must be an LS or LT model, or it must currently be running the correct 16-inch wheel package. Within 245/75R16, compare construction, load capacity, rim-width compatibility, sidewall treatment, and the kind of tread character that suits how the Suburban 2500 is actually used.
The available BFGoodrich All-Terrain T/A KO2 in this size adds an all-terrain personality and raised white letter styling, with a 3,042-pound maximum load rating at 80 psi and a 6.5- to 8.0-inch rim-width range. Those details are useful only when they match the vehicle's wheel setup and intended duty.
What sidewall styles are available for 2007 Chevrolet Trucks Suburban 2500 tires?
Among the currently available products for this fitment, the visible sidewall style is RWL, or raised white letter, in the 245/75R16 size. That gives the tire a more assertive truck-oriented appearance than a plain blackwall and can influence the overall look of an LS or LT Suburban 2500.
Sidewall style should be chosen with both appearance and vehicle character in mind. A heavy-duty SUV can wear a more utility-focused presentation well, but the sidewall treatment still needs to be paired with the correct size, wheel diameter, and intended use so appearance does not override proper fitment.
What brands offer tires for the 2007 Chevrolet Trucks Suburban 2500?
Current product coverage for this fitment includes BFGoodrich in the 245/75R16 size. The available example is the All-Terrain T/A KO2, a radial tire with raised white letter sidewalls intended for buyers who want a more truck-oriented look and tread character on the 16-inch setup.
Brand is only one part of the decision. The more important comparison points are whether the tire is being chosen for the correct trim, whether the wheel size matches, and whether the tire's load rating, rim-width range, and overall character suit a Suburban 2500 that may still see real carrying or towing duty.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Chevrolet Trucks Suburban 2500?
A period-style choice starts with keeping the Suburban 2500 in its correct trim-based size. That means 245/75R16 for LS and LT models or 275/55R20 for LTZ models. Preserving the original wheel diameter does more for the vehicle's overall stance and visual balance than changing to a different size for convenience alone.
Appearance decisions can then focus on tread style and sidewall treatment. A raised white letter all-terrain look gives a stronger truck presentation on a 16-inch setup, while a buyer chasing strict originality should compare the vehicle against model-specific sales literature, build documentation, or marque references before settling on one visual style.
Does correct tire fitment matter for a 2007 Chevrolet Trucks Suburban 2500 restoration?
Yes, because this model uses different tire and wheel packages depending on sub-model. An LS or LT restored on 20-inch tires, or an LTZ converted to the 16-inch fitment without considering wheel and appearance differences, can change the vehicle's stance and move it away from a trim-appropriate presentation.
Correct fitment also affects more than looks. Wheel diameter, tire profile, and tire width influence how the Suburban sits and how much clearance is available at the suspension and body. A restoration-minded buyer should confirm the actual trim, wheel setup, and use goals before choosing between staying original-style or adopting later modifications.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Chevrolet Trucks Suburban 2500?
Yes. Aftermarket wheels, suspension changes, lift or lowering adjustments, and body modifications can all affect tire fitment on a 2007 Chevrolet Trucks Suburban 2500. Those changes can alter wheel diameter, width, offset, and clearance, which matters whether the vehicle is supposed to use 245/75R16 or 275/55R20 tires.
A modified Suburban should be checked at the actual wheel and tire level rather than by trim alone. Steering clearance, suspension travel, and room at the fender edges all deserve attention, especially on a heavy-duty SUV that may carry passengers, cargo, or towing-related load that changes how the vehicle sits.
What should I inspect before driving a 2007 Chevrolet Trucks Suburban 2500 on new tires?
Before road use, inspect the wheels for the correct diameter and condition, confirm proper inflation, and make sure the tires clear the suspension and bodywork through a full steering sweep. It is also wise to look over the vehicle's alignment condition and check that the wheel hardware and valve stems are in sound shape.
A heavy-duty Suburban places real demands on its tires, so basic condition checks matter even when the tires are new. Uneven ride height, worn steering parts, or damaged wheels can create problems that look like tire issues, making it worthwhile to confirm the whole rolling setup before regular driving or a longer trip.
How often should tires on a 2007 Chevrolet Trucks Suburban 2500 be inspected?
Tires on a 2007 Chevrolet Trucks Suburban 2500 should be inspected regularly, not just at service intervals. Pressure, tread wear, cuts, cracking, bulges, and signs of slow air loss all deserve routine attention, especially on a vehicle that may sit for stretches and then return to carrying passengers or heavier loads.
Inspection frequency should increase before highway trips, towing use, or seasonal road use after storage. A Suburban 2500 that is driven infrequently can age its tires without adding many miles, so condition and age matter alongside tread depth. Clean storage conditions and protection from heat and sunlight also help preserve tire health.
