2017 Infiniti Trucks Tire Fitment Guide

2017 Infiniti Trucks vehicles use ten different sizes across five models: QX30 in 235/50R18 or 235/45R19, QX50 in 225/55R18 or 245/45R19, QX60 in 235/65R18 or 235/55R20, QX70 in 265/60R18 or 265/45R21, and QX80 in 275/60R20 or 275/50R22. All of them are radial sizes, but they do not share one common fitment across the lineup. Rim width guidance is available for 235/50R18 at 6.5 to 8.5 inches and for 245/45R19 at 7.5 to 9 inches.

That means year and make alone are not enough for a confident tire choice on 2017 Infiniti Trucks. Start by identifying the exact QX model, then confirm whether the vehicle is on its 18-, 19-, 20-, 21-, or 22-inch wheel package. Once the wheel diameter is confirmed, the correct tire size usually becomes much easier to narrow down.

On a 2017 Infiniti Trucks tire, 235/50R18 is a metric radial code. The 235 is the section width in millimeters, 50 is the aspect ratio, the R identifies radial construction, and 18 is the wheel diameter in inches. On 2017 Infiniti Trucks, that size belongs to the QX30. Available examples include blackwall BFGoodrich and Nitto products, with W speed ratings reaching 168 mph and rim-width guidance centered in the 6.5- to 8.5-inch range.

That decoding matters because a 235/50R18 is not interchangeable with the QX30's 235/45R19 alternative unless the wheel itself also changes. The first size number tells you width, but the final number controls wheel diameter, which is the hard fitment point. If your QX30 still wears its original wheel package, checking the sidewall of the existing tire is usually the quickest confirmation.

No, 2017 Infiniti Trucks models do not use the same tire size. Each model has its own pair of fitments: the QX30 uses 235/50R18 or 235/45R19, the QX50 uses 225/55R18 or 245/45R19, the QX60 uses 235/65R18 or 235/55R20, the QX70 uses 265/60R18 or 265/45R21, and the QX80 uses 275/60R20 or 275/50R22. Every one of those sizes is model-specific rather than universal across the brand's 2017 truck range.

For a buyer, that means the right starting point is the model badge and wheel diameter, not just the fact that it is a 2017 Infiniti Trucks product. Two vehicles from the same year and make can differ by several inches of wheel diameter and by major changes in width and profile. Matching the exact model first prevents chasing a tire that is correct for another QX but wrong for yours.

The available 2017 Infiniti Trucks products in 235/50R18 and 245/45R19 are blackwall radials. That suits the modern luxury crossover character of the QX30 and QX50, where a plain sidewall is consistent with contemporary original-equipment appearance rather than a wide whitewall or vintage-style bias-ply look. No sidewall-style split appears within the currently covered products for those two sizes.

If appearance matters as much as fitment, blackwall keeps the result visually clean and closest to what most 2017 Infiniti Trucks owners expect on a late-model premium utility vehicle. The larger decision on this page is not sidewall dress, but making sure the exact metric size and wheel diameter match your model. Once that is confirmed, sidewall style is straightforward for the sizes with product coverage here.

BFGoodrich and Nitto both cover 2017 Infiniti Trucks in the sizes with product availability here. For 235/50R18, BFGoodrich offers multiple g-Force family options plus the g-Force Phenom T/A, while Nitto offers the NT555 G2. For 245/45R19, BFGoodrich and Nitto appear again, with BFGoodrich spanning both all-season and higher-speed performance-oriented choices.

That gives QX30 and QX50 owners a useful brand comparison within the same exact size rather than forcing a jump to a different fitment. Brand choice can shape tread personality and speed-rating range, but it should come after the size is settled. On 2017 Infiniti Trucks, the first buying decision is still model and wheel package, with brand selection following from that confirmed fitment.

In 235/50R18 for 2017 Infiniti Trucks, BFGoodrich and Nitto both offer blackwall radial choices, but their details are not identical. BFGoodrich examples include 97W and 101W fitments, with weights around 26 to 29.01 pounds and load figures up to 1,819 pounds at 50 psi on some products. The Nitto NT555 G2 is a 101W XL tire weighing 27.86 pounds, with a 1,819-pound load figure at 50 psi and a rim-width range centered around 6.5 to 8.5 inches.

For a QX30 owner, that means the comparison can come down to the exact load index, speed symbol, and casing specification rather than simple size alone, since all of them share the same 235/50R18 fitment. If your vehicle sees regular highway use or carries more load, those small spec differences are worth checking before choosing. The sidewall remains blackwall across the group, so the visual difference is minimal.

Rim width guidance is size-specific on 2017 Infiniti Trucks. For 235/50R18, the available products fit rims from 6.5 to 8.5 inches wide. For 245/45R19, the covered products fit rims from 7.5 to 9 inches wide. Those ranges apply to the tire sizes themselves, not to every wheel used across the full 2017 Infiniti Trucks lineup.

The practical takeaway is to match the tire to the wheel you actually have, especially if your vehicle has aftermarket wheels or if you are replacing wheels and tires together. A tire can have the right diameter but still want a different wheel width for proper support and tread shape. Confirming wheel width before purchase helps preserve handling balance and prevents an avoidable mismatch.

The available 2017 Infiniti Trucks products covered here are modern radial tires without tube-type markings. Their size descriptions use contemporary metric and ZR-style notation rather than the TT markings associated with tube-type construction. That points buyers toward tubeless radial use on the appropriate wheels for the covered 235/50R18 and 245/45R19 sizes.

Even so, wheel condition still matters. If a wheel has been repaired, corroded, or replaced with something outside original specifications, have the bead seat and valve area inspected before mounting a new tire. On late-model luxury crossovers such as 2017 Infiniti Trucks vehicles, the safer assumption is modern tubeless service unless the exact product marking or wheel design says otherwise.

A 2017 Infiniti Trucks vehicle should be stored clean, dry, and out of direct sunlight, with the tires kept away from ozone-producing sources such as electric motors, battery chargers, and welders. Maintain normal inflation, avoid long-term parking on wet ground, and move the vehicle periodically so the same section of tread does not carry the load for months at a time. Modern radials tolerate storage better than old bias-ply designs, but they still age from time, heat, and environment.

If the vehicle will sit for an extended season, a climate-stable garage and regular pressure checks do more for tire life than simply covering the bodywork. Owners who keep a collector or second-use Infiniti for long stretches should also inspect sidewalls for early weathering before the next drive. Storage habits often decide whether a lightly used tire stays serviceable or ages out early.

On a 2017 Infiniti Trucks vehicle, tire life should be judged by age as much as by tread depth. A sound rule is to begin careful evaluation around five to seven years and to give serious replacement consideration by about ten years, even if the tire still looks usable and the vehicle has seen low mileage. The DOT date code on the sidewall is the clearest reference point for that age check.

That matters especially on premium crossovers and SUVs that may spend long periods parked, because low annual mileage can hide age-related hardening and cracking. A tire that still has tread can still be past its best service window. If your 2017 Infiniti Trucks vehicle is driven occasionally rather than daily, calendar age should carry more weight than miles when planning replacement.

Tires on a 2017 Infiniti Trucks vehicle deserve a quick inspection before every drive and a more thorough inspection before any longer trip. Look for sidewall cracking, cuts, punctures, bulges, irregular tread wear, and any sign that pressure has dropped since the last outing. Because these vehicles use larger-diameter modern radial sizes, also pay attention to inside-edge wear that may be less visible without turning the steering or raising the vehicle.

That routine is more useful than waiting for a mileage milestone, especially if the vehicle is used irregularly. A pre-drive walkaround can catch a low tire, curb damage, or a developing alignment issue before it becomes a roadside problem. If one tire is wearing differently from the others, treat that as a prompt to inspect suspension, alignment, and inflation habits rather than just replacing rubber.

The 2017 Infiniti Trucks QX30 used modern radial tires from the factory-era fitment pattern, specifically 235/50R18 or 235/45R19 depending on wheel package. That is consistent with a 2017 luxury crossover, where metric radial construction and low-profile sizing were standard practice rather than specialty or vintage tire formats. The correct original-style direction is therefore to stay with the exact metric radial size matched to the wheel diameter on the vehicle.

For authenticity on a late-model vehicle, the biggest concerns are exact size, proper speed and load category, and keeping the tire visually in step with the crossover's original character. If the vehicle is being preserved to very strict marque standards, compare against factory manuals, door-jamb labels, and owner-community references for your exact trim and wheel package. That is especially useful if the vehicle has changed hands or received aftermarket wheels.

Correct tire fitment does matter when showing a 2017 Infiniti Trucks vehicle, even though it is a newer-era collectible rather than a prewar or muscle-car restoration. Judges and knowledgeable enthusiasts typically notice whether the tire size matches the wheel package, whether the sidewall appearance suits the model year, and whether the overall stance looks factory-correct. On a 2017 vehicle, an obviously wrong aspect ratio or wheel-diameter mismatch stands out more quickly than a brand difference.

For most events, staying with the proper metric radial size for your exact QX model and wheel package is the cleanest path. Blackwall styling also fits the period character of a late-model Infiniti much better than a novelty sidewall treatment. If you are preparing for marque-specific judging, verify standards with the hosting organization, since some events care more about factory appearance while others focus mostly on overall condition and correctness.

For 2017 Infiniti Trucks in 245/45R19, BFGoodrich offers both the g-Force Comp 2 A/S and the g-Force Phenom T/A. Both are blackwall radials on a 19-inch rim and both fit the QX50 application, but the Phenom T/A carries a 102Y service description with a speed ceiling of 186 mph or higher, while the Comp 2 A/S appears here as a 98W tire with a 168 mph ceiling. The Phenom T/A also shows a 7.5- to 9-inch rim-width range and a 1,874-pound load figure at 50 psi.

That makes the choice less about visual style and more about the exact service description you want within the same size. A buyer comparing the two should review speed symbol, load index, and intended use before assuming they are interchangeable beyond basic dimensions. On a QX50, either can match the wheel diameter and tire size, but the detailed spec line is what separates them.

Yes, 2017 Infiniti Trucks tires in the covered product range are modern radials intended for normal road use, and the available speed ratings are comfortably above ordinary U.S. highway speeds. The 235/50R18 options include W-rated products with a 168 mph ceiling, and the 245/45R19 options include both W-rated products at 168 mph and a Y-rated product at 186 mph or higher. On vehicles of this age and type, the tire is rarely the limiting factor at legal highway speeds when the rest of the vehicle is in sound condition.

The more meaningful safety question is whether the exact tire size, inflation, age, and vehicle condition are all correct together. Suspension wear, alignment, brake condition, and neglected air pressure will affect real-world safety sooner than the speed symbol alone. If your 2017 Infiniti Trucks vehicle has sat for long periods, inspect the tires carefully before assuming a high speed rating means the whole package is ready for travel.

Inflation pressure on 2017 Infiniti Trucks should follow the vehicle placard and owner's manual first, because factory pressure targets are vehicle-specific and can differ even between similar-looking QX models. Tire pressure figures on the tire itself reflect maximum rated pressure for load carrying, not the normal operating pressure the vehicle necessarily calls for. In the covered products, some 235/50R18 and 245/45R19 tires show maximum load-and-pressure pairings around 50 to 51 psi, but those numbers should not be transferred blindly from one size or model to another.

The right habit is to confirm the exact size on the vehicle, then compare the door-jamb placard with the tire manufacturer's sidewall information and use the vehicle recommendation for routine driving unless a specialist setup calls for something different. Pressure should always be checked cold. If handling, wear pattern, or load use has changed from stock conditions, review the setup with a qualified tire professional.

Before a longer drive in a 2017 Infiniti Trucks vehicle, inspect each tire for cracks, cuts, punctures, bulges, and uneven wear, then verify cold inflation pressure and tread condition. Check the spare as well, since a neglected spare is common on SUVs and crossovers that otherwise appear road-ready. If the vehicle has 19-, 20-, 21-, or 22-inch wheels, also look closely for curb damage or bent-rim symptoms that can cause vibration or slow air loss.

Tires are only one part of the trip-prep routine on a modern luxury utility vehicle. It is equally wise to confirm brake feel, fluid levels, battery condition, and that any tire-pressure monitoring warnings are resolved before departure. A quick inspection at home is far easier than diagnosing a shake, warning light, or pressure problem once the vehicle is fully loaded and already on the road.
