The 2008 Chevrolet Trucks Suburban 1500 sits in the full-size SUV tradition that made the Suburban a long-running choice for families, towing, travel, and everyday utility. By this point, the Suburban balanced heavy-duty presence with modern comfort, which makes tire fitment especially important because wheel and trim combinations vary within the same model year. The 2008 Chevrolet Trucks Suburban 1500 uses radial tire fitments in 265/70R17, 265/65R18, and 275/55R20 depending on sub-model. That means the key decision is not just brand or tread style, but confirming the exact trim and wheel diameter first. Once that is settled, the focus shifts to load rating, road use, and maintaining proper SUV fitment.
Which Tire Size Is Right for The 2008 Chevrolet Trucks Suburban 1500
Three tire sizes apply to the 2008 Chevrolet Trucks Suburban 1500, and the right one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they use different 17-inch, 18-inch, or 20-inch rims. The first step is confirming whether the vehicle is an LS, LT, LT w/Z71 Pkg., or LTZ, then matching that trim to the wheel already on the vehicle before comparing tire choices.
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series aspect ratio, and fitment on a 17-inch rim. On the 2008 Chevrolet Trucks Suburban 1500, this size is used on specific trims and suits the vehicle's full-size SUV role with a traditional sidewall profile. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and differing load capacities. This size is worth considering when the Suburban is equipped with 17-inch wheels and the goal is to keep the intended wheel diameter and overall stance in place.
275/55R20 is a metric radial size that uses a 275-millimeter nominal section width, a 55-series aspect ratio, and a 20-inch rim. On the 2008 Chevrolet Trucks Suburban 1500, this size belongs to certain higher-wheel-diameter configurations rather than every version of the model. Its lower profile relative to the 17-inch and 18-inch options makes wheel confirmation especially important before replacement. This is the size to evaluate when the vehicle already carries 20-inch wheels and the objective is to stay with that larger rim package rather than shifting to another wheel and tire combination.
265/65R18 is a metric radial size with a 265-millimeter nominal section width, a 65-series aspect ratio, and fitment on an 18-inch rim. For the 2008 Chevrolet Trucks Suburban 1500, this size is tied to a specific sub-model rather than the full range, so it should not be treated as universal across all trims. Its overall dimensions place it close to the other Suburban 1500 fitments while still requiring the correct 18-inch wheel. This size makes sense when preserving the existing trim-specific wheel setup is more important than changing appearance or moving to a different rim diameter.
2008 Chevrolet Trucks Suburban 1500 Sub-Model Tires
Sub-model fitment matters on the 2008 Chevrolet Trucks Suburban 1500 because tire size changes with trim and wheel package. Some versions share the same size, while others move to a different rim diameter, so confirming the exact sub-model is the quickest way to avoid ordering the wrong tire.

2008 Chevrolet Trucks Suburban 1500 LS
The 2008 Chevrolet Trucks Suburban 1500 LS uses the 265/70R17 radial tire size. Tire selection here centers on staying with the correct 17-inch fitment and comparing available load ratings, sidewall presentation, and intended road use within that size.
The 2008 Chevrolet Trucks Suburban 1500 LT can use either 265/70R17 or 275/55R20, depending on the wheel package on the vehicle. The important step is confirming whether the LT has 17-inch or 20-inch wheels before comparing tires, since the two sizes are not interchangeable across rim diameters.
The 2008 Chevrolet Trucks Suburban 1500 LT w/Z71 Pkg. uses the 265/65R18 radial tire size. Choosing a tire for this version means matching the 18-inch wheel setup and keeping clearance, ride height, and overall vehicle balance consistent with the Z71-equipped configuration.
The 2008 Chevrolet Trucks Suburban 1500 LTZ uses the 275/55R20 radial tire size. Tire selection for this trim begins with confirming the 20-inch wheel package, then focusing on the kind of road use, load needs, and appearance expected from a full-size SUV with larger-diameter wheels.
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.

Current product choices for the 2008 Chevrolet Trucks Suburban 1500 are centered on 265/70R17, with BFGoodrich All-Terrain T/A KO2 options available in raised white letter form. The key differences to compare are load capacity, rim-width compatibility, and the intended balance between everyday SUV use and more rugged all-terrain duty.
Common questions for the 2008 Chevrolet Trucks Suburban 1500 usually come down to trim-specific tire size, wheel diameter, radial fitment, product selection, and the checks worth making before putting a full-size SUV back on the road.
Tire Size & Fitment
What tire size fits a 2008 Chevrolet Trucks Suburban 1500?
The 2008 Chevrolet Trucks Suburban 1500 uses three tire sizes depending on sub-model and wheel package: 265/70R17, 265/65R18, and 275/55R20. All are radial metric sizes, but they do not share the same rim diameter, so they serve different trim and wheel combinations rather than one universal setup.
The practical step is to confirm the exact trim level and the wheel currently on the vehicle before selecting a tire. An LS uses 265/70R17, the LT can use either 265/70R17 or 275/55R20, the LT w/Z71 Pkg. uses 265/65R18, and the LTZ uses 275/55R20.
What size rim does a 2008 Chevrolet Trucks Suburban 1500 use?
A 2008 Chevrolet Trucks Suburban 1500 can use 17-inch, 18-inch, or 20-inch rims depending on trim. The 265/70R17 tire fits a 17-inch rim, the 265/65R18 fits an 18-inch rim, and the 275/55R20 fits a 20-inch rim.
Wheel diameter should be checked before anything else because each tire size is built around a specific rim size. Even when the overall tire heights are relatively close, moving between these fitments means changing wheel diameter, so the right replacement starts with the wheel already on the vehicle.
Why does the 2008 Chevrolet Trucks Suburban 1500 have more than one tire size?
The 2008 Chevrolet Trucks Suburban 1500 has more than one tire size because different sub-models and wheel packages were used across the lineup. LS, LT, LT w/Z71 Pkg., and LTZ versions do not all share the same wheel diameter, which leads to different tire sizes within the same model year.
That matters because a Suburban owner cannot choose by model name alone. The safest approach is to identify the trim and confirm whether the vehicle has 17-inch, 18-inch, or 20-inch wheels, especially if it has had replacement wheels installed at some point in its service life.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2008 Chevrolet Trucks Suburban 1500?
A 265/70R17 tire for a 2008 Chevrolet Trucks Suburban 1500 should first match the correct 17-inch wheel setup used on the vehicle. After that, the main points are radial construction, load capacity, rim-width compatibility, and whether the tire's tread character suits everyday road use, trail use, or a mix of both.
Available 265/70R17 options include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and differing load ratings. That means selection is less about finding the size and more about matching the tire's carrying capability and use case to how the Suburban is actually driven.
What sidewall styles are available for 2008 Chevrolet Trucks Suburban 1500 tires?
The available product selection for the 2008 Chevrolet Trucks Suburban 1500 currently includes RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich 265/70R17 all-terrain options and gives the tire a more pronounced traditional truck-and-SUV appearance.
Sidewall style is mostly an appearance decision, but it still works best when paired with the correct tire size, wheel diameter, and intended use. On a full-size Suburban, an RWL tire can change the visual character noticeably, so it is worth deciding whether the goal is understated factory-like simplicity or a more assertive truck presentation.
What brands offer tires for the 2008 Chevrolet Trucks Suburban 1500?
BFGoodrich is represented in the current tire selection for the 2008 Chevrolet Trucks Suburban 1500, specifically in 265/70R17 through the All-Terrain T/A KO2 line. Those options remain within the correct radial size while offering different load capacities for buyers comparing how the vehicle is used.
Brand choice should still come after confirming the exact Suburban trim and wheel diameter, because the model uses more than one tire size. Once the fitment is verified, the next comparison points are sidewall style, tread character, and whether the tire's specifications align with the SUV's passenger, cargo, or mixed-use duty.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Chevrolet Trucks Suburban 1500?
A period-style choice for a 2008 Chevrolet Trucks Suburban 1500 starts with keeping the correct trim-specific size and wheel diameter in place. Since this model uses modern radial metric sizes, a period-appropriate look usually comes from preserving the original wheel-and-sidewall visual balance rather than moving to an unrelated size.
That means an LS, LT, LT w/Z71 Pkg., or LTZ should be matched to its proper 17-inch, 18-inch, or 20-inch fitment before appearance choices are made. For owners who want the most authentic presentation, factory literature, dealer brochures, and marque-specific references are useful for confirming how a particular Suburban was equipped.
How does tire construction affect the appearance of a restored 2008 Chevrolet Trucks Suburban 1500?
Tire construction has less visual impact here than it would on an older collector vehicle because the 2008 Chevrolet Trucks Suburban 1500 uses radial fitments across its primary sizes. The bigger appearance factors are the correct metric size, the wheel diameter, the sidewall height, and any sidewall treatment such as raised white letters.
A restored or exceptionally clean Suburban can look noticeably off if the tire profile does not match the wheel package intended for that trim. Staying with the proper 265/70R17, 265/65R18, or 275/55R20 fitment preserves the vehicle's overall stance far better than chasing appearance with the wrong wheel-and-tire combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Chevrolet Trucks Suburban 1500?
Modifications can absolutely affect tire fitment on a 2008 Chevrolet Trucks Suburban 1500. Aftermarket wheels, suspension lifts, lowering changes, altered offsets, or body modifications can change the clearances that the original 265/70R17, 265/65R18, or 275/55R20 fitments were designed around.
That is why the actual wheel diameter and width on the vehicle should be checked instead of relying only on trim name. Steering clearance, inner-fender room, and suspension travel are all worth reviewing before replacing tires, especially on a used Suburban that may have changed from its original setup.
What should I inspect before driving a 2008 Chevrolet Trucks Suburban 1500 on new tires?
Before driving a 2008 Chevrolet Trucks Suburban 1500 on new tires, inspect wheel condition, valve stems, lug torque, and inflation pressure, then confirm that the tire size matches the wheel diameter on the vehicle. It is also wise to look for uneven suspension wear or alignment issues that may affect how the new tires settle in.
A full-size SUV places real demands on its tires, so side-to-side clearance and steering travel should be checked as well. A short test drive followed by a second pressure and visual inspection can help catch rubbing, air loss, or mounting issues early, before the Suburban goes back into regular use.
How often should tires on a 2008 Chevrolet Trucks Suburban 1500 be inspected?
Tires on a 2008 Chevrolet Trucks Suburban 1500 should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, cuts, punctures, sidewall damage, and signs of aging all deserve routine attention, particularly on a vehicle that may alternate between daily use, towing duty, and longer idle periods.
A monthly visual check is a sensible baseline, with an added inspection before road trips or heavier hauling. Full-size SUVs can hide problems until they become more serious, so catching irregular wear early may point to alignment, suspension, or inflation issues before they shorten tire life.
