The 2009 Dodge Trucks Nitro came from an era when midsize SUVs balanced everyday utility with a more aggressive, street-ready look, and the Nitro leaned hard into that bold styling. Its wheel-and-tire fitment reflects that split personality, with different sub-models using 16-, 17-, or 20-inch radial sizes depending on the trim and package. That makes tire selection less about broad Dodge SUV fitment and more about confirming the exact setup on the vehicle. Some versions center on a practical 225/75R16 or 235/65R17, while R/T and certain SLT applications move to 245/50R20. Before choosing a replacement, verify the sub-model and actual wheel diameter, especially on vehicles that may have been changed over time.
Which Tire Size Is Right for The 2009 Dodge Trucks Nitro
Three primary tire sizes apply to the 2009 Dodge Trucks Nitro, and the right one depends on the exact sub-model and wheel package. These are all radial fitments, but they do not share one rim diameter, so the first step is confirming whether the Nitro is on 16-, 17-, or 20-inch wheels. Once that is settled, the decision becomes choosing the right tire style and specifications within the correct size.
245/50R20 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2009 Dodge Trucks Nitro, this size is associated with trims that use a larger-diameter wheel and a lower-profile tire presentation. Its role is distinct from the 16- and 17-inch Nitro fitments, so it should be selected only after the wheel size and trim are confirmed. This size is the right starting point when the vehicle carries the larger factory-style wheel setup.
225/75R16 is a metric radial size with a 225-millimeter nominal section width, a 75-series profile, radial construction, and a 16-inch rim diameter. On the 2009 Dodge Trucks Nitro, it serves the smaller-wheel fitment used on certain SE package configurations. Available product choice in this size includes an LT-spec BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving this fitment a more rugged replacement path than a street-oriented appearance. This size should be evaluated with close attention to wheel diameter and intended use, especially if the Nitro has seen aftermarket wheel changes.
235/65R17 is a metric radial size where 235 is the nominal width in millimeters, 65 is the aspect ratio, R marks radial construction, and 17 is the required rim diameter in inches. For the 2009 Dodge Trucks Nitro, this size fills the middle ground between the 16-inch and 20-inch setups and appears on certain SE and SLT configurations. It is a primary fitment rather than an alternate description of the other Nitro sizes, so it needs to match the actual wheel on the vehicle. This size makes sense only after the exact sub-model and wheel package have been confirmed.
2009 Dodge Trucks Nitro fitment varies by sub-model and package, so trim identification matters before choosing tires. Some versions use a single tire size, while others were offered with more than one wheel-and-tire combination, making a quick wheel-diameter check especially important.

2009 Dodge Trucks Nitro R/T
The 2009 Dodge Trucks Nitro R/T uses the 245/50R20 radial fitment, which places it on the largest wheel diameter used across the Nitro range. Tire selection starts with confirming that 20-inch setup, then comparing replacement choices that suit the vehicle's appearance and road use.
The 2009 Dodge Trucks Nitro SE (B Pkg.) uses the 225/75R16 radial size, giving this package a distinct 16-inch fitment. That makes wheel confirmation straightforward, and the next step is choosing a replacement tire that matches the intended use of the vehicle.
The 2009 Dodge Trucks Nitro SE (C Pkg.) can use either the 225/75R16 or 235/65R17 radial fitment, so this package needs an extra wheel check before any tire is selected. Matching the replacement tire to the actual 16- or 17-inch wheel is more important here than assuming all SE models use the same setup.
The 2009 Dodge Trucks Nitro SLT uses either 235/65R17 or 245/50R20, depending on the wheel-and-tire configuration on the vehicle. That makes the SLT a trim where visual confirmation of wheel diameter should come first, followed by a replacement choice that fits the Nitro's actual setup.
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 2009 Dodge Trucks Nitro Tires for Sale

These 2009 Dodge Trucks Nitro tire FAQs focus on trim-specific sizing, wheel diameter, radial fitment, available product choices, and the basic checks worth making before putting a collector or daily-driven Nitro back on the road.
Tire Size & Fitment
What tire size fits a 2009 Dodge Trucks Nitro?
A 2009 Dodge Trucks Nitro uses one of three radial tire sizes: 225/75R16, 235/65R17, or 245/50R20. The correct size depends on the exact sub-model and wheel package, with R/T using 245/50R20, SE (B Pkg.) using 225/75R16, and other trims such as SE (C Pkg.) and SLT potentially using more than one size.
That means the first step is not comparing tread patterns or sidewall style, but confirming the wheel diameter already on the vehicle. A Nitro that has had wheels replaced over the years may no longer match its original trim-based setup, so checking the current tire sidewall and wheel size is the safest starting point.
What size rim does a 2009 Dodge Trucks Nitro use?
The 2009 Dodge Trucks Nitro uses 16-inch, 17-inch, or 20-inch rims depending on the sub-model and package. The tire sizes match those wheel diameters directly: 225/75R16 fits a 16-inch rim, 235/65R17 fits a 17-inch rim, and 245/50R20 fits a 20-inch rim.
Rim diameter is the most important fitment check because none of these sizes crosses over to another wheel size. A buyer choosing tires for an SE (C Pkg.) or SLT should verify the actual wheel on the vehicle before ordering, since those trims can appear with more than one original fitment.
Why does the 2009 Dodge Trucks Nitro have more than one tire size?
The 2009 Dodge Trucks Nitro has more than one tire size because different sub-models and packages used different wheel-and-tire combinations. Some versions were fitted with 16-inch wheels, others with 17-inch wheels, and others with 20-inch wheels, which is why the Nitro range includes 225/75R16, 235/65R17, and 245/50R20.
That variation changes the tire decision from a simple year-make-model lookup to a trim-and-wheel confirmation exercise. It is especially important on SE (C Pkg.) and SLT models, where more than one size applies, because a correct replacement depends on the actual wheel diameter and setup on the vehicle today.
Choosing the Right Tire
What should I consider when choosing a 225/75R16 tire for a 2009 Dodge Trucks Nitro?
Start with the basics: the Nitro must actually be using the 225/75R16 fitment on a 16-inch wheel. In this size, available product choice includes a radial BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, a 6.0 to 7.0 inch rim-width range, and a maximum load capacity of 2,680 lbs @ 80 psi.
Those details help narrow the decision toward intended use as much as size alone. A buyer should compare the tire's construction, sidewall style, load specification, and wheel-width compatibility against the Nitro's actual wheels and how the vehicle will be driven, especially if it has seen suspension or wheel changes.
What sidewall styles are available for 2009 Dodge Trucks Nitro tires?
Among the currently covered 2009 Dodge Trucks Nitro products, the visible sidewall style is RWL, or raised white letter, in the 225/75R16 fitment. That gives the 16-inch Nitro setup a more assertive truck-style presentation than a plain blackwall would, while still staying within the correct radial size family.
Sidewall style is mainly an appearance choice once the correct tire size and wheel diameter are confirmed. It should be treated as the finishing detail rather than the first decision, because the right size, proper wheel match, and intended use all matter more than lettering style on the sidewall.
What brands offer tires for the 2009 Dodge Trucks Nitro?
Current product coverage for the 2009 Dodge Trucks Nitro includes BFGoodrich in the 225/75R16 fitment. The available tire in that size is the All-Terrain T/A KO2, which gives buyers a recognizable all-terrain option when the Nitro is equipped with the 16-inch wheel setup.
Brand should be part of the comparison, but it is not the only factor that matters. The right way to narrow the choice is to confirm the Nitro's actual tire size first, then compare construction, sidewall presentation, rim-width compatibility, and load-related specifications within the size that belongs on the vehicle.
Restoration & Appearance
Does correct tire fitment matter for a 2009 Dodge Trucks Nitro restoration?
Yes, correct tire fitment matters because the 2009 Dodge Trucks Nitro used multiple wheel-and-tire combinations across its sub-models. A restoration-minded replacement should begin with the proper trim and wheel diameter, whether that means 225/75R16, 235/65R17, or 245/50R20, rather than choosing a tire only by appearance.
The visual stance of the Nitro changes noticeably between the 16-, 17-, and 20-inch setups, so tire size has a direct effect on how authentic the vehicle looks. Buyers pursuing a more exact restoration should compare the current wheel package to vehicle-specific records or marque references before finalizing tires.
How does tire construction affect the appearance of a restored 2009 Dodge Trucks Nitro?
The 2009 Dodge Trucks Nitro uses radial tire fitments, so the construction question here is less about bias-ply versus radial and more about selecting the right size and sidewall presentation within a radial setup. On the covered products, the clearest appearance variation is the raised white letter look available in 225/75R16.
Appearance still depends heavily on matching the wheel diameter and tire proportions to the Nitro's original-style configuration. A restored R/T on 20-inch wheels presents very differently from an SE package on 16-inch wheels, so the correct fitment should drive the visual decision before sidewall treatment becomes the final detail.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Dodge Trucks Nitro?
Yes, modifications can affect tire fitment on a 2009 Dodge Trucks Nitro. Aftermarket wheels, suspension changes, lowering, or body modifications can alter the wheel diameter, wheel width, and available clearance, which matters even more on a vehicle that already had multiple original tire sizes across different trims.
A Nitro with changed wheels may not match the original trim-based fitment at all, so checking the actual tire size and wheel before replacement is essential. It also helps to inspect steering and fender clearance at full lock and over suspension travel so the new tire matches the vehicle's present configuration.
What should I inspect before driving a 2009 Dodge Trucks Nitro on new tires?
Before driving a 2009 Dodge Trucks Nitro on new tires, inspect the wheels for damage, verify that the tire size matches the actual rim diameter, and make sure inflation is set appropriately for the tire being used. It is also worth checking for rubbing points, uneven wear patterns, and any obvious alignment or suspension issues.
A short road test should confirm that the Nitro tracks straight, steers cleanly, and has no contact at the fenders or inner wheelhouse. Vehicles that have sat for long periods deserve extra attention to valve stems, air retention, and age-related condition in any remaining spare or matching tires.
How often should tires on a 2009 Dodge Trucks Nitro be inspected?
Tires on a 2009 Dodge Trucks Nitro should be inspected regularly, especially if the vehicle is driven infrequently or stored for long periods. Routine checks should include tread wear, sidewall cracking, cuts, bulges, punctures, and air loss, along with a quick look at whether all four tires still match the intended size and wheel setup.
Frequent inspections matter because the Nitro can wear anything from a 16-inch to a 20-inch package, and problems are easier to miss when the vehicle is not used daily. Looking over the tires before longer drives, seasonal use, or highway trips helps catch condition issues before they turn into roadside problems.
