The 2011 Chevrolet Trucks Suburban 1500 sits firmly in the modern full-size SUV world, blending long-wheelbase family hauling with the truck-based durability that has defined the Suburban name for generations. Buyers looking at this model usually need to sort out trim-specific wheel packages before choosing a tire, because this Suburban 1500 uses three different radial sizes: 265/70R17, 265/65R18, and 275/55R20. That means the real decision is not just tire type, but also matching the correct rim diameter and overall look to the exact LS, LT, LT w/Z71 Pkg., or LTZ configuration. For road use, utility, or appearance, wheel setup comes first.
Which Tire Size Is Right for The 2011 Chevrolet Trucks Suburban 1500
The 2011 Chevrolet Trucks Suburban 1500 uses three different primary tire sizes, and the correct one depends on the exact sub-model and wheel package. These are all radial metric sizes, but they do not share the same rim diameter, so the first step is confirming whether the vehicle is on 17-inch, 18-inch, or 20-inch wheels before comparing tire options.
A 265/70R17 tire uses a 265-millimeter section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. On the 2011 Chevrolet Trucks Suburban 1500, this size serves as one of the primary trim-level fitments and suits buyers who need to stay with the factory wheel diameter already on the vehicle. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. This size is worth considering when the Suburban is equipped with 17-inch wheels and the goal is to keep the correct rim fitment while choosing among load and use characteristics.
A 275/55R20 tire has a 275-millimeter section width, a 55-series profile, radial construction, and a 20-inch rim. On this Suburban 1500, it is tied to specific upper-trim or optional wheel configurations rather than every version of the model. Its lower-profile metric format gives the buyer a distinct wheel-and-tire package to verify before selection, especially if the vehicle has changed hands or seen wheel swaps over time. This size should be evaluated by owners who have confirmed a 20-inch wheel setup and want to match the Suburban's existing fitment rather than substitute across rim diameters.
A 265/65R18 tire combines a 265-millimeter section width with a 65-series profile, radial construction, and an 18-inch rim. For the 2011 Chevrolet Trucks Suburban 1500, this size applies to a specific sub-model configuration and should not be treated as a universal fitment across the lineup. Its metric radial sizing places it between the 17-inch and 20-inch packages in wheel diameter while remaining a separate fitment choice. This is the right size to evaluate when the Suburban already wears 18-inch wheels and the goal is to maintain the intended wheel diameter and tire proportions for that setup.
2011 Chevrolet Trucks Suburban 1500 Sub-Model Tires
Tire fitment on the 2011 Chevrolet Trucks Suburban 1500 varies by sub-model, and some trims share a size while others use a different wheel package. Checking the exact LS, LT, LT w/Z71 Pkg., or LTZ configuration is the key step before choosing a tire.

2011 Chevrolet Trucks Suburban 1500 LS
The 2011 Chevrolet Trucks Suburban 1500 LS uses the 265/70R17 radial size. Tire selection here centers on staying with the 17-inch wheel setup and comparing product details such as load specification, sidewall treatment, and intended use within that size.
The 2011 Chevrolet Trucks Suburban 1500 LT can use either 265/70R17 or 275/55R20, depending on the wheel package on the vehicle. That makes wheel confirmation especially important, since the correct tire choice depends on whether the Suburban is equipped with 17-inch or 20-inch rims.
The 2011 Chevrolet Trucks Suburban 1500 LT w/Z71 Pkg. uses the 265/65R18 radial size. Tire shopping for this version starts with the 18-inch wheel fitment, then moves to choosing a tire that suits the vehicle's actual road use and present wheel setup.
The 2011 Chevrolet Trucks Suburban 1500 LTZ uses the 275/55R20 radial size. Buyers should confirm that the vehicle still carries its 20-inch wheel package, then compare tire options within that size rather than assuming another Suburban 1500 size will cross over.
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)

Tire questions for the 2011 Chevrolet Trucks Suburban 1500 usually come down to trim-specific sizing, wheel diameter, product selection, and maintenance. The answers below focus on choosing the correct metric radial size and checking the vehicle before road use.
Tire Size & Fitment
What tire size fits a 2011 Chevrolet Trucks Suburban 1500?
The 2011 Chevrolet Trucks Suburban 1500 uses three possible tire sizes: 265/70R17, 265/65R18, and 275/55R20. All three are radial metric fitments, but they do not apply across every version of the vehicle. LS models use 265/70R17, LT can use either 265/70R17 or 275/55R20, LT w/Z71 Pkg. uses 265/65R18, and LTZ uses 275/55R20.
Choosing the right one starts with identifying the exact sub-model and then confirming the wheel diameter currently on the vehicle. On a used Suburban, that matters because wheel packages can change over time. Once the trim and rim size are confirmed, tire selection becomes much more straightforward.
What size rim does a 2011 Chevrolet Trucks Suburban 1500 use?
A 2011 Chevrolet Trucks Suburban 1500 can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and wheel package. The 265/70R17 size mounts on a 17-inch rim, 265/65R18 mounts on an 18-inch rim, and 275/55R20 mounts on a 20-inch rim.
That makes rim diameter the first fitment check before ordering tires. Looking only at the model name is not enough, especially on LT trims that could have more than one wheel setup. Checking the tire sidewall and measuring the installed wheel diameter helps prevent choosing the right overall tire type in the wrong rim size.
Why does the 2011 Chevrolet Trucks Suburban 1500 have more than one tire size?
The 2011 Chevrolet Trucks Suburban 1500 has more than one tire size because different sub-models and wheel packages use different rim diameters. LS uses 265/70R17, LT w/Z71 Pkg. uses 265/65R18, and LTZ uses 275/55R20. The LT trim can use either 265/70R17 or 275/55R20.
That variation means tire selection is tied to the actual wheel package, not just the badge on the liftgate. A Suburban that has been modified or fitted with take-off wheels from another trim can complicate the picture. Verifying the installed wheel and reading the current sidewall size are the safest ways to narrow the fitment.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2011 Chevrolet Trucks Suburban 1500?
A 265/70R17 tire for the 2011 Chevrolet Trucks Suburban 1500 should first match the correct wheel diameter and the trim that uses that size. In the available choices, BFGoodrich All-Terrain T/A KO2 options are offered with raised white letter sidewalls, radial construction, and different load specifications.
Selection comes down to how the Suburban is actually used and which product details matter most on that setup. Comparing load capacity, tire weight, and the wheel-width range can help narrow the choice. It is also worth checking whether the vehicle sees everyday road use, towing, or more utility-focused driving.
What sidewall styles are available for 2011 Chevrolet Trucks Suburban 1500 tires?
Among the currently available products tied to this Suburban 1500 fitment, the visible sidewall style is RWL, or raised white letter, on the 265/70R17 BFGoodrich All-Terrain T/A KO2 options. Sidewall presentation affects the vehicle's look even when the tire size and basic fitment remain the same.
That makes sidewall style a useful choice once the correct size has been confirmed. Some owners prefer a more traditional truck appearance, while others may want a cleaner, less prominent sidewall look if other options become available in the same size. The first priority still remains matching the exact wheel diameter and tire size.
What brands offer tires for the 2011 Chevrolet Trucks Suburban 1500?
Current product coverage for the 2011 Chevrolet Trucks Suburban 1500 includes BFGoodrich in 265/70R17, specifically the All-Terrain T/A KO2 series. That gives buyers a recognizable all-terrain style option within one of the Suburban's primary radial sizes.
Brand choice only matters after the trim and wheel setup are confirmed, because this Suburban uses more than one size across the lineup. Once the correct size is established, compare the available tire's load rating, weight, sidewall style, and wheel-width compatibility to make sure the selection matches the vehicle's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Chevrolet Trucks Suburban 1500?
For a period-style 2011 Chevrolet Trucks Suburban 1500, the starting point is keeping the tire size that matches the vehicle's actual trim and wheel package. This model uses modern metric radial sizing, so the right visual approach usually comes from maintaining the correct 17-inch, 18-inch, or 20-inch fitment rather than changing construction style.
Appearance should be balanced with how the Suburban is used today. A raised white letter all-terrain look can give a more truck-oriented presentation on a 265/70R17 setup, while other trims may call for staying with the wheel diameter and profile already associated with that package. Checking period brochures or marque-specific references can help when originality matters closely.
Does correct tire fitment matter for a 2011 Chevrolet Trucks Suburban 1500 restoration?
Correct tire fitment matters because the 2011 Chevrolet Trucks Suburban 1500 did not use one universal size across the whole model range. The visual stance, wheel fill, and overall presentation of the vehicle are all affected by whether it wears the proper 17-inch, 18-inch, or 20-inch tire package.
Using the wrong rim diameter or profile can change the look even before road manners enter the discussion. On a restoration-minded Suburban, confirming the sub-model and present wheel setup helps preserve the intended appearance of that trim. It also reduces the chance of mixing sizes that belong to another configuration of the same year.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Chevrolet Trucks Suburban 1500?
Yes, modifications can affect tire fitment on a 2011 Chevrolet Trucks Suburban 1500. Aftermarket wheels, suspension changes, leveling kits, lowered ride height, or body alterations can all change the space available for the tire, even when the vehicle started with one of the correct original size ranges.
That is especially important here because the Suburban already came with multiple rim diameters from the factory. A modified truck may no longer match its original trim-based fitment exactly. Checking wheel diameter, wheel width, and clearance at full steering lock helps avoid choosing a tire size that suits the model on paper but not the current setup.
What should I inspect before driving a 2011 Chevrolet Trucks Suburban 1500 on new tires?
Before driving a 2011 Chevrolet Trucks Suburban 1500 on new tires, inspect the wheel size, verify the installed tire matches the intended sub-model fitment, and confirm proper inflation. It is also smart to look over the wheels for damage and make sure the tires have adequate clearance around suspension components and bodywork.
A short follow-up check after initial driving is worthwhile on a full-size SUV like the Suburban. Rechecking pressure, looking for uneven contact or rubbing, and making sure lug hardware is secure can catch small issues early. On a vehicle with replacement wheels or past modifications, that second inspection becomes even more valuable.
How often should tires on a 2011 Chevrolet Trucks Suburban 1500 be inspected?
Tires on a 2011 Chevrolet Trucks Suburban 1500 should be inspected regularly, not only when tread looks worn. A quick visual check for cuts, bulges, cracking, punctures, and uneven wear should be part of normal ownership, and pressure should be checked routinely as well.
Longer gaps between drives can make inspections even more important, especially on a vehicle that sees seasonal or occasional use. Looking over the sidewalls and tread before a trip helps catch age-related issues or slow air loss early. Consistent inspections also help confirm that the tire is wearing correctly for the vehicle's wheel and suspension setup.
