The 2016 Infiniti Trucks QX50 sits in the compact luxury crossover space with a strong emphasis on responsive road manners, upscale touring comfort, and sporty stance. It is a vehicle where wheel and tire choice noticeably shape both appearance and everyday driving character. For this model year, the QX50 uses radial tire fitments in two sizes, 225/55R18 and 245/45R19, so the first step is confirming which wheel package is on the vehicle. The available product mix leans toward modern blackwall performance-oriented radials in the 19-inch size. That makes this page especially useful for owners checking wheel diameter, preserving intended proportions, and matching replacement tires to the QX50's actual setup.
Which Tire Size Is Right for The 2016 Infiniti Trucks QX50
The 2016 Infiniti Trucks QX50 uses two primary tire sizes, and the difference comes down to wheel diameter. One fitment uses an 18-inch rim and the other uses a 19-inch rim, so confirming the wheels on the vehicle is the first step before comparing replacement tires. Once that is settled, the decision shifts to choosing the right radial tire within the correct size and intended driving style.
225/55R18 is a metric radial size in which 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2016 Infiniti Trucks QX50, this size represents the 18-inch wheel fitment and keeps the tire selection rooted in modern radial construction. Its sizing format is familiar to late-model buyers and is aimed more at matching the proper wheel package than at choosing among period-style variations. The practical priority is confirming that the vehicle actually carries 18-inch wheels before moving ahead with replacement selection.
245/45R19 is a metric radial size where 245 indicates nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 19 identifies the wheel diameter in inches. For the 2016 Infiniti Trucks QX50, this size belongs to the 19-inch fitment and brings a lower-profile presentation than the 18-inch option. Available choices in this size include BFGoodrich and Nitto blackwall radials across g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. It is the size to evaluate when the QX50 is already equipped with 19-inch wheels and the goal is selecting among modern performance-oriented replacements.
Sub-model fitment is straightforward here because the 2016 Infiniti Trucks QX50 Base is the covered configuration. Even so, checking the actual wheel setup still matters, since this sub-model uses both 18-inch and 19-inch tire fitments.

Owners shopping tires for a 2016 Infiniti Trucks QX50 usually need to confirm the correct size first, then sort through wheel diameter, product choice, and road-use considerations. The questions below focus on fitment, radial tire selection, appearance, and practical checks before driving.
Tire Size & Fitment
What tire size fits a 2016 Infiniti Trucks QX50?
The 2016 Infiniti Trucks QX50 uses two tire sizes: 225/55R18 and 245/45R19. Both are radial fitments, and the correct one depends on which wheel package is on the vehicle rather than on a different tire construction choice.
The key step is checking the actual wheel diameter before ordering replacement tires. A QX50 on 18-inch wheels needs the 225/55R18 size, while a vehicle on 19-inch wheels needs 245/45R19, and using the wrong rim diameter will stop the tire from matching the wheel.
What size rim does a 2016 Infiniti Trucks QX50 use?
The 2016 Infiniti Trucks QX50 uses either an 18-inch or 19-inch rim, depending on the tire size installed. The 225/55R18 fitment uses an 18-inch rim, and the 245/45R19 fitment uses a 19-inch rim.
That makes wheel confirmation more important than anything else in the initial fitment check. Looking only at sidewall width or overall tire appearance is not enough, because the tire must match the wheel diameter exactly before comparing brand, series, or other replacement details.
Why does the 2016 Infiniti Trucks QX50 have more than one tire size?
The 2016 Infiniti Trucks QX50 has more than one tire size because it was fitted with more than one wheel diameter. Its primary fitments are 225/55R18 and 245/45R19, both radial sizes intended for different wheel setups on the same model line.
This is a wheel-package question more than a sub-model question, since the QX50 Base uses both sizes. The practical takeaway is to inspect the wheels and current sidewall markings on the vehicle, then choose replacement tires that match that exact diameter and size before comparing available products.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Infiniti Trucks QX50?
Start with the correct size for the wheel package on the vehicle: 225/55R18 for 18-inch wheels or 245/45R19 for 19-inch wheels. From there, focus on radial construction, intended driving use, and product details such as rim-width compatibility, load-related specifications, and the overall character of the tire series.
The best comparison comes after the basic fitment is settled. A QX50 used mainly for daily road driving may call for a different feel than one whose owner prefers a more performance-focused replacement, so matching the tire to both the wheel size and the vehicle's actual use matters.
What sidewall styles are available for 2016 Infiniti Trucks QX50 tires?
Available products for the 2016 Infiniti Trucks QX50 in the 245/45R19 fitment use a blackwall sidewall style. That gives the vehicle a clean, modern appearance that suits the QX50's late-model luxury crossover character without introducing vintage-style whitewalls or decorative sidewall treatments.
Sidewall style is mostly an appearance decision once the correct size is confirmed. On this vehicle, blackwall choices keep the focus on proper modern fitment and tire series selection, so owners comparing options should pay closer attention to size, wheel compatibility, and the intended driving character of the tire.
What brands offer tires for the 2016 Infiniti Trucks QX50?
BFGoodrich and Nitto offer tires for the 2016 Infiniti Trucks QX50 in the available 245/45R19 product selection. Within that size, BFGoodrich appears in the g-Force Comp 2 AS and g-Force Phenom T/A series, while Nitto appears in the NT555 G2 series.
Brand alone should not be the only filter. Comparing the correct size, series character, rim-width fitment, and any load-related specification that matters to the vehicle's use will give a clearer picture than choosing only by brand name, especially when several modern radial performance-oriented options are in play.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Infiniti Trucks QX50?
A period-style approach on a 2016 Infiniti Trucks QX50 starts by staying with the correct original-format radial size for the wheel package already on the vehicle: 225/55R18 or 245/45R19. Because this is a modern luxury crossover, the visual goal is usually preserving its stock-era proportions rather than recreating a vintage sidewall treatment.
Keeping the proper wheel diameter and tire profile does more for the vehicle's appearance than chasing a dramatic styling change. Owners who want the QX50 to retain its model-year look should compare the actual wheel setup, tire proportions, and sidewall presentation before moving to a different size or wheel package.
Does correct tire fitment matter for a 2016 Infiniti Trucks QX50 restoration?
Correct tire fitment matters on a 2016 Infiniti Trucks QX50 because the vehicle's look and stance depend heavily on wheel diameter and sidewall proportion. Using the proper 225/55R18 or 245/45R19 size keeps the replacement tire aligned with the wheel package the vehicle was built around.
Even on a newer collector-minded vehicle, appearance and fitment go together. A tire that changes the visual balance or does not match the wheel correctly can alter how the QX50 sits and drives, so careful size verification is just as important as brand or tread design when refreshing the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Infiniti Trucks QX50?
Yes, modifications can affect tire fitment on a 2016 Infiniti Trucks QX50. Aftermarket wheels, suspension changes, lowering, or changes in wheel width can alter the clearance relationship that the original 225/55R18 and 245/45R19 fitments were built around.
A modified QX50 should be checked for wheel diameter, width, and surrounding clearance before replacement tires are chosen. Steering travel, fender space, and suspension condition all matter once the original setup has been changed, so the safest approach is to verify the actual hardware on the vehicle rather than assume stock fitment remains.
What should I inspect before driving a 2016 Infiniti Trucks QX50 on new tires?
Before driving a 2016 Infiniti Trucks QX50 on new tires, inspect the wheel size, mounting condition, inflation pressure, and general clearance around the tire. It is also smart to check for uneven wear signs, damaged wheels, and any suspension or alignment issue that may have affected the old tires.
A short visual inspection after installation can prevent larger problems later. Look for sidewall interference, confirm that the tire sits correctly on the wheel, and pay attention to any vibration or rubbing on the first drive, since those symptoms can point to a fitment or condition issue that needs attention.
How often should tires on a 2016 Infiniti Trucks QX50 be inspected?
Tires on a 2016 Infiniti Trucks QX50 should be inspected regularly rather than only at replacement time. Routine checks for pressure loss, tread wear, cuts, bulges, and sidewall cracking are important on any vehicle, and they matter just as much on a luxury crossover that may see mixed city and highway use.
Frequent inspection helps catch issues before they affect ride quality or safety. It also gives the owner a chance to spot wheel damage, uneven wear, or aging that may suggest alignment, suspension, or storage concerns, especially if the vehicle is driven less often or sits for longer periods between trips.
