The 2017 Infiniti Trucks QX30 blends compact luxury crossover packaging with a distinctly sporty edge, giving it a place between premium hatchback and small utility vehicle. Its styling and road manners push tire choice toward both appearance and everyday drivability, especially on vehicles still wearing their original wheel diameter. The 2017 Infiniti Trucks QX30 uses radial tires, with 235/50R18 and 235/45R19 fitments depending on sub-model and wheel setup. Available choices center on modern performance-oriented radial construction, with differences in brand, tire series, and sidewall treatments such as blackwall, redline, and raised white letter. The key is confirming the exact sub-model and wheel diameter before comparing tire style and specifications.
Which Tire Size Is Right for The 2017 Infiniti Trucks QX30
Two tire sizes apply to the 2017 Infiniti Trucks QX30, and the first thing to confirm is wheel diameter. This model uses either an 18-inch or 19-inch radial tire depending on sub-model and equipment, so identifying the exact trim and checking the wheels currently on the vehicle matters before choosing a tire. Once that is settled, the decision shifts to brand, tire series, sidewall style, and the intended balance of appearance and road use.
Fit(s): Base, Luxury (AWD), Luxury (FWD), Premium (AWD), Premium (FWD), and Sport
Construction: Radial|Rim: 18 in
235/50R18 is a metric radial size in which 235 identifies nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2017 Infiniti Trucks QX30, this is one of the main fitments for 18-inch-wheel applications and suits the vehicle’s modern crossover layout. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and raised white letter sidewall treatments across several tire series. This size is the one to evaluate when the vehicle retains 18-inch wheels and the goal is to compare modern radial options without changing rim diameter.
235/45R19 is also a metric radial size, with the same 235-millimeter nominal width but a lower 45-series profile matched to a 19-inch wheel. For the 2017 Infiniti Trucks QX30, this size applies only to certain configurations, so it should not be assumed across the full model range. Its lower-profile format points the buyer toward confirming the actual wheel package before moving ahead with any replacement. This is the size to focus on when the vehicle is equipped with 19-inch wheels and maintaining that original wheel diameter is part of the fitment plan.
Tire fitment on the 2017 Infiniti Trucks QX30 varies by sub-model, and some versions can be found with either 18-inch or 19-inch fitments. Checking the exact trim and the wheels currently on the vehicle is the quickest way to narrow the correct tire size before comparing product options.

Tire Size & Fitment
What tire size fits a 2017 Infiniti Trucks QX30?
The 2017 Infiniti Trucks QX30 uses two tire sizes: 235/50R18 and 235/45R19. Both are radial fitments, but they do not apply universally across every sub-model. Base, Luxury AWD, Luxury FWD, and Premium AWD use 235/50R18, while Premium FWD and Sport can appear with either 235/50R18 or 235/45R19 depending on wheel setup.
The practical first step is to confirm the trim and then verify the actual wheel diameter on the vehicle. A QX30 with 18-inch wheels should stay in the 235/50R18 fitment range, while a 19-inch-wheel vehicle needs 235/45R19. That check matters even more on Premium FWD and Sport models, where more than one primary size can apply.
What size rim does a 2017 Infiniti Trucks QX30 use?
A 2017 Infiniti Trucks QX30 uses either an 18-inch or 19-inch rim, depending on the sub-model and wheel package. The 235/50R18 tire fits an 18-inch rim, and the 235/45R19 tire fits a 19-inch rim. Both sizes are modern radial fitments rather than older bias-ply or vintage alphanumeric formats.
Wheel diameter is the quickest way to narrow the correct tire size before comparing products. Looking only at the trim name is not always enough, since some QX30 Premium FWD and Sport vehicles can be associated with more than one fitment. Checking the sidewall of the current tire and measuring the installed wheel package helps avoid ordering the wrong rim diameter.
Why does the 2017 Infiniti Trucks QX30 have more than one tire size?
The 2017 Infiniti Trucks QX30 has more than one tire size because different sub-models and wheel packages use different rim diameters. The two primary fitments are 235/50R18 and 235/45R19. That difference is tied to whether the vehicle is equipped with 18-inch or 19-inch wheels rather than a change from one tire construction type to another.
This means tire selection starts with the actual wheel setup on the vehicle, not just the model name on the liftgate. A lower-profile 19-inch fitment and an 18-inch fitment are not interchangeable without changing wheels. On vehicles that may have been modified, it is smart to verify the current wheel diameter and clearance before choosing a replacement tire.
Choosing the Right Tire
What should I consider when choosing a 235/50R18 tire for a 2017 Infiniti Trucks QX30?
Start with the correct size and confirm that the QX30 is on 18-inch wheels, since 235/50R18 is only one of the model’s primary fitments. From there, compare radial tire series, rim-width compatibility, sidewall style, and any stated load figures. In this size, available choices include BFGoodrich, Nitto, and Pro-Trac products with different performance-oriented radial offerings.
The right pick depends on how the vehicle is used and how closely the owner wants to match a modern blackwall look versus a more distinctive redline or raised white letter presentation. It also helps to compare the installed wheel width against the tire’s recommended range when that specification is given, especially if the vehicle no longer has its original wheels.
What sidewall styles are available for 2017 Infiniti Trucks QX30 tires?
For the 2017 Infiniti Trucks QX30, available 235/50R18 products include blackwall, redline, and RWL sidewall styles. Blackwall is the most common presentation among the current options, while redline and raised white letter versions appear in the Pro-Trac Street Pro III line. All of these choices remain radial tires in the correct 18-inch size format.
Sidewall style mainly changes the visual character of the vehicle rather than the basic fitment category. A blackwall keeps the appearance understated and contemporary, while redline or raised white letter tires create a more customized look. The key is to choose the sidewall treatment only after confirming that the tire size, wheel diameter, and intended use all match the vehicle.
What brands offer tires for the 2017 Infiniti Trucks QX30?
Available tires for the 2017 Infiniti Trucks QX30 include products from BFGoodrich, Nitto, and Pro-Trac in the 235/50R18 fitment. These brands cover several radial tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III. Each brings a slightly different combination of sidewall styling and specification detail.
Brand choice should come after the size and wheel diameter are confirmed. Once fitment is settled, compare sidewall style, rim-width compatibility, load figures where shown, and the overall look you want for the vehicle. Since the QX30 can appear with either 18-inch or 19-inch wheel setups, make sure the brand options being compared actually match the size on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Infiniti Trucks QX30?
A period-style approach on a 2017 Infiniti Trucks QX30 usually starts by keeping the correct wheel diameter and tire size for the specific sub-model, then choosing a radial tire whose look matches the vehicle’s original-era character. For an 18-inch setup, that can mean a straightforward blackwall or a more personalized option such as redline or raised white letter, depending on the appearance goal.
Because the QX30 is a modern luxury crossover rather than a vintage restoration candidate, appearance decisions are more about preserving the vehicle’s design balance than chasing antique tire styling. Staying close to the proper size maintains the right visual proportion. Owners who want the closest historical presentation should compare the current wheel and tire package to original vehicle documentation.
Does correct tire fitment matter for a 2017 Infiniti Trucks QX30 restoration?
Correct tire fitment still matters on a 2017 Infiniti Trucks QX30, even though it is a newer vehicle than most traditional restorations. The correct size keeps the visual proportions tied to the intended wheel package, and it avoids mixing 18-inch and 19-inch fitments in a way that changes stance or appearance. On this model, that means confirming whether the vehicle belongs in 235/50R18 or 235/45R19.
Appearance is only part of the story. Using the right size also helps preserve proper clearance, wheel compatibility, and the overall look the body and wheel arches were designed around. If the QX30 has aftermarket wheels, lowered suspension, or a changed tire setup, verify those details first so the replacement tire supports both the appearance goal and the actual hardware on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Infiniti Trucks QX30?
Yes, modifications can affect tire fitment on a 2017 Infiniti Trucks QX30. Wheel changes, altered offsets, suspension lowering, and non-original wheel diameters can all change which tire size works properly. That matters on this model because both 235/50R18 and 235/45R19 are valid primary fitments, and the vehicle may already be different from its original trim-based wheel setup.
A modified QX30 should be checked for actual wheel diameter, wheel width, steering clearance, and fender space before choosing replacement tires. Even when the sidewall shows one of the recognized sizes, aftermarket hardware can change how much room is available. Confirming the current setup helps prevent rubbing, mismatched wheel-to-tire pairing, or selecting a tire that suits the trim but not the vehicle as it sits now.
What should I inspect before driving a 2017 Infiniti Trucks QX30 on new tires?
Before driving a 2017 Infiniti Trucks QX30 on new tires, inspect wheel diameter, tire pressure, valve stems, lug hardware, and the general condition of the wheels themselves. It is also worth checking for suspension wear, uneven old tire wear patterns, and any signs of alignment issues. Those steps matter whether the vehicle uses 235/50R18 or 235/45R19.
A quick visual inspection after installation helps catch problems early. Look for proper seating on the rim, adequate clearance to suspension and fender surfaces, and any sign of rubbing when the steering is turned from lock to lock. After a short drive, recheck inflation and listen for vibration or contact noises so the new tires are working with the vehicle rather than exposing an existing setup issue.
How often should tires on a 2017 Infiniti Trucks QX30 be inspected?
Tires on a 2017 Infiniti Trucks QX30 should be inspected regularly, not only when replacement time arrives. A routine check should include tread condition, uneven wear, cuts, bulges, air loss, and sidewall damage. Because this model may use either 18-inch or 19-inch fitments, it also helps to confirm that all four tires match the intended size and wheel package for the vehicle.
Monthly pressure checks and frequent visual inspections are a sensible baseline, especially if the QX30 sees mixed city and highway use. It is also smart to inspect the tires before a longer drive or after any impact with potholes or curbs. Catching wear or damage early can reveal alignment, suspension, or wheel issues before they turn into a more expensive fitment problem.
