The 2006 Chevrolet Trucks Trailblazer sits in the era when midsize SUVs were expected to balance daily comfort, family utility, and a more substantial truck-based feel. In Trailblazer form, that means tire choice affects not just appearance, but also ride height, wheel presence, and how the vehicle carries itself on the road. This model uses radial tire fitments in three sizes: 235/75R16, 245/65R17, and 255/50R20, depending on sub-model and wheel package. That makes the first step identifying the exact Trailblazer configuration and wheel diameter. From there, the decision shifts toward maintaining the intended stance and choosing a tire that matches the vehicle's use and overall presentation.
Which Tire Size Is Right for The 2006 Chevrolet Trucks Trailblazer
Three primary tire sizes apply to the 2006 Chevrolet Trucks Trailblazer, and they vary by sub-model and wheel diameter. All are radial fitments, but the difference between 16-inch, 17-inch, and 20-inch wheels makes wheel confirmation the first step before selecting a tire. Once the correct size is established, the real choice becomes matching the tire to the Trailblazer's intended use, appearance, and product availability within that size.
235/75R16 is a metric radial size in which 235 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2006 Chevrolet Trucks Trailblazer, this size suits configurations that use a 16-inch wheel and delivers a more traditional SUV tire profile. Its taller sidewall gives the vehicle a distinctly different visual balance than the larger-wheel alternatives. This is the size to evaluate when maintaining the original wheel diameter matters more than moving to a lower-profile appearance.
245/65R17 is a metric radial size with a 245-millimeter nominal section width, a 65-series profile, radial construction, and a 17-inch rim diameter. For the 2006 Chevrolet Trucks Trailblazer, it represents the middle fitment between the 16-inch and 20-inch options and is available in BFGoodrich's All-Terrain T/A KO2 line with raised white letter styling. That gives this size a more specific product character than a plain replacement-size listing alone would suggest. It is the right size to consider when the Trailblazer uses 17-inch wheels and the goal includes a more truck-oriented sidewall presentation.
255/50R20 is a metric radial size where 255 indicates nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter. On the 2006 Chevrolet Trucks Trailblazer, this size is tied to the 20-inch wheel setup rather than the smaller-wheel configurations. Its shorter sidewall changes the vehicle's stance and makes wheel diameter confirmation especially important before any replacement decision. This is the fitment to focus on when preserving the intended SS-style wheel presence is part of the overall tire choice.
Sub-model fitment matters on the 2006 Chevrolet Trucks Trailblazer because tire size is not the same across the full lineup. LS and LT can use 16-inch or 17-inch fitments, while SS uses a separate 20-inch setup, so identifying the exact model and wheel diameter comes before choosing a tire.

2006 Chevrolet Trucks Trailblazer LS
The 2006 Chevrolet Trucks Trailblazer LS uses radial tire fitments on either 16-inch or 17-inch wheels, depending on the vehicle's actual setup. Tire selection starts with confirming which wheel diameter is on the SUV now, then choosing a replacement that matches the intended ride height, use, and sidewall look.
The 2006 Chevrolet Trucks Trailblazer LT also uses radial tires and can be equipped with either the 235/75R16 or 245/65R17 size. That makes wheel verification essential, especially on vehicles that may have changed wheels over time or moved between factory-style and aftermarket setups.
The 2006 Chevrolet Trucks Trailblazer SS uses the 255/50R20 radial fitment, which separates it clearly from the smaller-wheel LS and LT configurations. Tire selection here is centered on maintaining the 20-inch wheel setup and checking clearance, wheel condition, and overall dimensions before any change in tire model.
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 2006 Chevrolet Trucks Trailblazer?
The 2006 Chevrolet Trucks Trailblazer uses three primary radial tire sizes: 235/75R16, 245/65R17, and 255/50R20. The correct size depends on the Trailblazer sub-model and wheel package, with LS and LT using 16-inch or 17-inch fitments and SS using the 20-inch fitment.
The practical first step is confirming the wheel diameter actually on the vehicle. A Trailblazer may still have its original wheel setup, but replacement wheels or trim-specific variations can change what size belongs on it. Matching the tire to the current wheel diameter is more important than choosing by appearance alone.
What size rim does a 2006 Chevrolet Trucks Trailblazer use?
A 2006 Chevrolet Trucks Trailblazer can use 16-inch, 17-inch, or 20-inch rims, depending on the exact sub-model and tire size. The 235/75R16 fitment uses a 16-inch rim, 245/65R17 uses a 17-inch rim, and 255/50R20 uses a 20-inch rim.
Rim diameter should be confirmed before any tire purchase because these sizes are not interchangeable across different wheel diameters. Checking the sidewall marking on the current tire and measuring the wheel if needed helps avoid selecting the right overall type of tire in the wrong rim size.
Why does the 2006 Chevrolet Trucks Trailblazer have more than one tire size?
The 2006 Chevrolet Trucks Trailblazer has more than one tire size because fitment varies across the lineup. LS and LT models can use either 235/75R16 or 245/65R17, while the Trailblazer SS uses 255/50R20, reflecting a different wheel and tire presentation.
That variation means the correct tire choice is tied to the exact model and wheel setup rather than the Trailblazer name alone. It is smart to verify the sub-model, check the wheel diameter on the vehicle, and make sure the replacement tire matches the current setup before comparing brands or tread styles.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Chevrolet Trucks Trailblazer?
Start with the correct primary size for the specific Trailblazer: 235/75R16, 245/65R17, or 255/50R20. From there, compare construction, wheel diameter, overall tire profile, and whether the vehicle is being kept in a stock-style setup or has changed wheels since new.
Selection becomes more specific once the size is confirmed. A taller sidewall and a lower-profile 20-inch fitment give the Trailblazer very different visual and driving character, so the best choice depends on how the SUV is used and whether preserving its existing stance matters more than changing its look.
What sidewall styles are available for 2006 Chevrolet Trucks Trailblazer tires?
Current product coverage for the 2006 Chevrolet Trucks Trailblazer includes a raised white letter sidewall in 245/65R17. That style appears on the BFGoodrich All-Terrain T/A KO2 and gives the Trailblazer a more truck-oriented, traditional utility look than a plain black sidewall presentation.
Sidewall style does not change the required tire size, but it does influence the vehicle's overall appearance. Owners choosing tires for a stock-height SUV or a more rugged visual theme may pay close attention to that detail, especially when the wheel and tire fill the wheel opening differently across 16-inch, 17-inch, and 20-inch setups.
What brands offer tires for the 2006 Chevrolet Trucks Trailblazer?
BFGoodrich is available in the 245/65R17 size for the 2006 Chevrolet Trucks Trailblazer. That product appears in the All-Terrain T/A KO2 series and provides a named brand option for Trailblazer owners using the 17-inch radial fitment.
Brand choice should still come after confirming the size and wheel diameter on the vehicle. Once that is settled, compare the product's sidewall style, rim-width specification, load capacity, and overall character to make sure it suits how the Trailblazer is driven rather than selecting a tire by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Chevrolet Trucks Trailblazer?
A period-style 2006 Chevrolet Trucks Trailblazer usually starts with keeping the correct wheel diameter and tire size for the exact configuration, whether that is 235/75R16, 245/65R17, or 255/50R20. Preserving that basic fitment does more for the vehicle's original visual balance than changing to a different wheel-driven look.
Appearance decisions then come down to sidewall treatment and tire character within the correct size. Trailblazers kept close to their original presentation benefit from avoiding unnecessary size changes, while owners seeking a more authentic restoration direction may also want to compare period photos, brochures, or marque-specific references before finalizing details.
How does tire construction affect the appearance of a restored 2006 Chevrolet Trucks Trailblazer?
On a 2006 Chevrolet Trucks Trailblazer, the primary fitments are radial tires, so the construction itself is already in line with the vehicle's era. The bigger appearance shift comes from the tire's profile and wheel diameter, since a 16-inch setup, 17-inch setup, and 20-inch setup give the SUV noticeably different proportions.
That means restoration-minded owners should focus first on keeping the correct size family for the exact sub-model and wheel package. Sidewall presentation also matters, especially when comparing a raised white letter tire to a more subdued look, because those details influence whether the finished Trailblazer reads as stock-style, sporty, or more utility-oriented.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Chevrolet Trucks Trailblazer?
Yes, modifications can affect tire fitment on a 2006 Chevrolet Trucks Trailblazer. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearance available for 235/75R16, 245/65R17, or 255/50R20 tires, even when the size itself is correct for a stock configuration.
A Trailblazer that has been lowered, lifted, or fitted with different wheels should be checked for steering clearance, fender room, and wheel-to-suspension clearance before replacing tires. Matching the original size code alone is not enough when the vehicle no longer sits on its original wheel and suspension setup.
What should I inspect before driving a 2006 Chevrolet Trucks Trailblazer on new tires?
Before driving a 2006 Chevrolet Trucks Trailblazer on new tires, inspect wheel condition, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the tire and vehicle setup. It is also worth checking for any obvious interference at full steering lock and normal ride height.
A quick road-use inspection should include lug fastener torque, valve stem condition, and a visual check for uneven suspension stance that could affect tire wear. Older SUVs also benefit from checking alignment and looking for worn steering or suspension parts, since those issues can shorten tire life even when the tire size is correct.
How often should tires on a 2006 Chevrolet Trucks Trailblazer be inspected?
Tires on a 2006 Chevrolet Trucks Trailblazer should be inspected regularly, not just when tread appears worn. Routine checks for air loss, uneven wear, cracking, cuts, bulges, and foreign objects help catch issues early, especially on an SUV that may see changing loads, seasonal use, or long periods between detailed maintenance.
Monthly pressure checks are a sensible habit, and a closer visual inspection before longer trips is worthwhile. Trailblazers with limited annual mileage still need attention because tire age and condition matter alongside tread depth, particularly when a vehicle spends time parked outdoors or is used only occasionally.
