2011 Infiniti Trucks Tire Fitment Guide

2011 Infiniti Trucks vehicles use seven sizes across four different models: EX35 uses 225/55R18 and 245/45R19, FX35 uses 265/50R20 and 265/60R18, FX50 uses 265/45R21, and QX56 uses 275/50R22 and 275/60R20. These are all radial metric sizes, but they do not interchange across the full lineup because the wheel diameters range from 18 to 22 inches.

That means the first fitment question is always model identification, followed by wheel diameter confirmation on the vehicle itself. Once those two points are settled, you can narrow to the correct size and then compare tire type, brand, sidewall appearance, and service rating within that exact application.

On a 2011 Infiniti Trucks EX35, 245/45R19 means the tire is 245 millimeters wide, has a 45-series aspect ratio, uses radial construction, and fits a 19-inch wheel. In available EX35 products, that size appears in performance-oriented radial designs from BFGoodrich and Nitto, all with Blackwall styling and W or Y speed ratings depending on the tire.

That code is important because each part affects what wheel the tire fits and how tall the tire will stand once mounted. A 245/45R19 should be matched only to a 19-inch EX35 wheel application, and then narrowed further by checking the exact tire's speed rating, load marking, and recommended rim-width range.

No, 2011 Infiniti Trucks models do not share a common tire size across the range. The EX35, FX35, FX50, and QX56 each have their own applications, and even within some models there are two different sizes tied to different wheel packages.

That model-specific variation matters more here than it would on a lineup with one shared wheel diameter. If you start with only the year and make, you can still narrow the field, but the correct tire choice does not become clear until you verify the model and the actual wheel size mounted on the vehicle.

For 2011 Infiniti Trucks applications covered here, the available 245/45R19 tires for the EX35 use Blackwall sidewalls. That suits the modern luxury and sport-crossover look of the 2011 Infiniti range, where a clean, contemporary sidewall appearance is generally more era-appropriate than vintage whitewall styling.

Sidewall appearance is mostly a styling decision once the correct size, load range, and speed rating are in place. If your EX35 uses 245/45R19, Blackwall choices keep the look consistent with the vehicle's factory-era character, while buyers using another model should first confirm the correct size before comparing appearance details.

Within the currently covered 2011 Infiniti Trucks product range, the 245/45R19 EX35 size is available from BFGoodrich and Nitto. BFGoodrich appears in both g-Force COMP-2 A/S and g-Force Phenom T/A form, while Nitto appears with the NT555 G2.

Brand choice on a modern luxury crossover often comes down to the kind of driving you expect and which service description best matches it. Once the vehicle has been confirmed as an EX35 with 19-inch wheels, compare the specific tire's speed symbol, load index, and rim-width compatibility instead of choosing by brand name alone.

The 245/45R19 choices for a 2011 Infiniti Trucks EX35 include BFGoodrich g-Force COMP-2 A/S, Nitto NT555 G2, and BFGoodrich g-Force Phenom T/A. All are radial Blackwall tires, but they differ in service description and weight: the BFGoodrich COMP-2 A/S is 98W at 29 pounds, the Nitto NT555 G2 is XL 102W at 29.65 pounds, and the BFGoodrich Phenom T/A is 102Y at 29.26 pounds with a 1,874-pound maximum load at 50 psi.

Those differences affect how closely each tire matches the wheel and service needs of your EX35. A buyer comparing them should focus on the load index, speed symbol, and whether the rim-width range matches the wheel already on the vehicle, then use weight and tire series character as secondary tie-breakers.

Rim-width guidance is available for the 245/45R19 size used on certain 2011 Infiniti Trucks EX35 applications. BFGoodrich specifies a 7.5- to 9.0-inch range for the g-Force COMP-2 A/S and 7.5- to 9-inch range for the g-Force Phenom T/A, which are effectively the same fitment window for that size.

That range gives EX35 owners a useful check before mounting a replacement tire on an existing 19-inch wheel. If the wheel falls outside that width span, the tire may not seat or perform as intended, so wheel measurement should be part of the fitment process rather than an afterthought.

The 2011 Infiniti Trucks applications here are modern radial metric sizes, and the available 245/45R19 EX35 products do not carry tube-type markings. That points buyers toward tubeless radial fitments for this application rather than the tube-type construction more common on earlier collector vehicles.

Even so, tube use should never be assumed across the full lineup without checking the exact tire and wheel combination. The practical step is to verify the sidewall marking on the specific tire and confirm the wheel's condition, valve hardware, and sealing surfaces before mounting.

Original 2011 Infiniti Trucks wheels cannot be treated as interchangeable across all seven sizes, because the lineup spans 18-, 19-, 20-, 21-, and 22-inch rim diameters. Each model's tire sizes are tied to its own wheel packages, and in several cases the same model could have more than one wheel diameter depending on configuration.

That makes wheel verification essential before replacing tires on an EX35, FX35, or QX56 with multiple factory size paths. The safe approach is to match the tire to the wheel already on the vehicle, then confirm the width range and service description for that exact size before mounting.

A 2011 Infiniti Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, furnaces, and other ozone sources that accelerate rubber aging. Radial tires generally tolerate storage better than older bias-ply designs, but they still benefit from periodic movement so one section of the tread is not carrying the vehicle's weight for months at a time.

If the vehicle will sit for an extended season, roll it occasionally or support it according to the owner's maintenance plan so the suspension and tires are not left under one static load indefinitely. Storage care matters just as much on a low-mile luxury crossover or SUV as it does on a classic collector car.

On a 2011 Infiniti Trucks vehicle, tire age is usually a more important measure than mileage alone, especially if the vehicle is driven occasionally. A sound rule is to begin careful evaluation once a tire reaches roughly five to seven years of age and to treat around ten years as the point where replacement deserves serious consideration regardless of tread depth, using the DOT date code to confirm age.

That matters because many premium SUVs and crossovers accumulate miles slowly while spending long periods parked. Even a tire that still looks usable can harden, crack, or lose its margin of safety with age, so replacement decisions should be based on time, condition, and service history, not just remaining tread.

Tires on a 2011 Infiniti Trucks vehicle should be inspected before every drive and again before any extended highway trip. Look for sidewall cracking, cuts, bulges, punctures, uneven wear, low pressure, and any sign that the tire has been run underinflated or damaged by impact.

A quick visual check catches problems early, while a more thorough inspection every few months helps you track age-related changes and alignment wear. On modern radial fitments like these, pressure retention and shoulder wear are especially useful clues, and the spare should be checked on the same schedule rather than ignored.

Yes, 2011 Infiniti Trucks tires can be suitable for highway driving when the correct size, load index, and speed rating are matched to the vehicle. In the available 245/45R19 EX35 fitment, W-rated tires carry a 168 mph ceiling and the Y-rated option carries a 186-plus mph ceiling, which is far beyond ordinary U.S. highway use.

Highway safety still depends on more than the speed symbol on the sidewall. Tire age, inflation pressure, wheel condition, alignment, suspension health, and brake condition all matter, and on an older luxury SUV or crossover those real-world factors usually deserve more attention than the tire's theoretical top-speed capability.

Inflation pressure for a 2011 Infiniti Trucks tire should follow the vehicle placard or owner's manual first, because factory pressure targets are set for the vehicle's weight distribution and handling balance. In the available 245/45R19 EX35 range, one BFGoodrich option carries a maximum load of 1,874 pounds at 50 psi, but that figure is the tire's rated maximum and should not be treated as the routine operating pressure for every application.

The practical approach is to use the vehicle's specified cold pressure as your baseline, then verify that the chosen tire's load capacity is appropriate at that pressure range. Do not transfer a pressure figure from one Infiniti model or one tire size to another, because the EX35, FX35, FX50, and QX56 do not share the same fitment needs.

Before a longer drive in a 2011 Infiniti Trucks vehicle, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and proper cold inflation pressure. Check valve stems, confirm that the spare is usable and inflated, and make sure the tire size on the vehicle matches the wheel diameter actually fitted to the model.

That tire check should be part of a broader pre-trip routine that also covers brakes, fluids, battery condition, lights, and suspension. On a luxury crossover or SUV with staggered wheel-package possibilities across the lineup, a few minutes spent confirming the exact size can prevent mounting mistakes and reduce the risk of trouble on the road.
