2017 BMW Trucks Tire Fitment Guide

2017 BMW Trucks vehicles use 14 sizes across five models. The X1 uses 225/50R18 and 225/45R19. The X3 and X4 share 245/50R18, 245/45R19, 245/40R20, 275/35R20, and 275/40R19. The X5 and X6 share 255/50R19, 275/40R20, 285/40R20, 315/35R20, 325/35R20, 285/35R21, and 325/30R21. Rim diameters span 18, 19, 20, and 21 inches, so there is no one-size-fits-all answer for the full 2017 BMW Trucks range.

The practical takeaway is that year and make alone are not enough when ordering for 2017 BMW Trucks vehicles. Start by identifying the exact model, then confirm wheel diameter, and on X5 or X6 applications confirm whether the vehicle uses a staggered front-and-rear combination. That step narrows the search quickly and avoids confusing a compact X1 fitment with the much wider sizes used on larger BMW sport activity models.

On a 2017 BMW Trucks tire, 225/50R18 is a metric radial size. The 225 is the nominal section width in millimeters, 50 is the aspect ratio, the R indicates radial construction, and 18 is the wheel diameter in inches. In the 2017 BMW Trucks range, that size is used on the X1 and mounts on 18-inch wheels. Available products in this size use Blackwall styling and carry W speed ratings up to 118 mph.

That code matters because it defines both the wheel diameter and the tire’s basic proportions. A 225/50R18 cannot substitute directly for a 19-inch X1 size, even though both belong to the same model family. If your X1 has 18-inch wheels, 225/50R18 is the size family to stay within; after that, compare product details such as rim width range, speed rating, and overall tread character.

No, 2017 BMW Trucks models do not use the same tire size. The X1 uses its own 225-width sizes, the X3 and X4 share a midsize group built around 245- and 275-width fitments, and the X5 and X6 move into much wider 255-, 275-, 285-, 315-, and 325-width combinations. Wheel diameters also vary, from 18 inches on smaller applications to 21 inches on some larger X5 and X6 packages.

That variation means the correct choice starts with model identification, not just with a preference for a certain tread pattern or appearance. It also means some BMW owners will be working with square setups while others may be dealing with staggered front and rear sizes. Checking the tire sidewall already on the vehicle and comparing front to rear is the fastest way to avoid a mismatch.

Most 2017 BMW Trucks tire options use a Blackwall sidewall, which is the dominant look across the X1, X3, X4, X5, and X6 sizes covered here. Two X3 and X4 sizes introduce more visible sidewall styling: 245/50R18 is available in RWL and Redline form, and 245/40R20 plus 275/35R20 include RWL choices alongside Blackwalls. Those alternatives change the visual presentation more than the basic size classification.

For a late-model BMW crossover or SUV, Blackwall is generally the most natural appearance and the closest match to the understated factory look most owners expect. RWL and Redline options can appeal to custom builds or owners who want a more distinctive side profile. If appearance matters as much as fitment, compare sidewall style only after confirming the exact size your model uses.

2017 BMW Trucks sizes are covered by BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. BFGoodrich appears across many 18-, 19-, and 20-inch fitments, Nitto covers several of the same performance-oriented sizes, Pro-Trac adds style-focused options in 245/50R18, 245/40R20, and 275/35R20, and M&H Racemaster appears in 275/40R20. Brand coverage varies by size rather than being uniform across the whole model range.

That matters because a buyer choosing for an X1 will see a different brand mix than a buyer choosing for an X5 or X6. Once the correct size is confirmed, brand selection becomes a matter of preferred tread family, speed rating, sidewall look, and intended use. Comparing brands within the same size is more useful than comparing them across unrelated BMW fitments.

For 2017 BMW Trucks sizes where both appear together, BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A share radial construction and Blackwall styling, but they differ in speed rating and some published load details. In sizes such as 225/45R19, 245/45R19, 245/40R20, 275/35R20, and 275/40R19, the Phenom T/A carries a Y speed rating up to 186+ mph, while the Comp 2 A/S uses W ratings up to 168 mph or, in some cases, lower depending on the size string.

The practical comparison is not about whether one physically fits and the other does not; both belong to the same size family when offered in the same size. Instead, the choice comes down to the exact product character you want within that fitment, along with the speed rating and any rim width or load details shown for that specific size. Always compare them size by size, not series by series in the abstract.

Several 2017 BMW Trucks sizes include rim width guidance. 225/45R19 fits 7.0 to 8.5 inches, 225/50R18 fits 6.0 to 8.0 inches, 245/45R19 fits 7.5 to 9.0 inches, 245/40R20 fits 8.0 to 9.5 inches, 275/35R20 fits 9.0 to 11.0 inches, 275/40R19 spans roughly 9.0 to 11.0 inches depending on product, and 275/40R20 ranges from a 9-inch application up to 11.0 inches depending on the tire. Rim width guidance is product-specific within each size.

That last point is important on BMW crossover and SUV applications because the same nominal size can appear in more than one tire family. If your wheel sits near the narrow or wide end of the approved range, confirm the exact product before making a final decision. That is especially useful on larger 19- and 20-inch BMW fitments where style, width, and speed rating can all vary within one size code.

The 2017 BMW Trucks products covered here are radial fitments without tube-type markings in the size descriptions, and they are best understood as tubeless modern applications. No TT markings appear in the available size strings, while several use contemporary performance-oriented metric radial sizing and speed ratings typical of tubeless construction. Tube use is not part of the normal selection path for these BMW crossover and SUV sizes.

Even so, the wheel itself still matters. If a wheel has been repaired, modified, or is not the original type intended for the vehicle, sealing and valve condition deserve a close inspection before mounting new tires. On a 2017 BMW Trucks application, confirm the wheel condition and valve hardware at the same time you confirm size, especially on larger-diameter packages that see higher load and speed capability.

A 2017 BMW Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, welders, or furnaces. Keep the tires clean, maintain inflation, and move the vehicle periodically so the same section of tread does not carry the load for months at a time. Radial tires generally tolerate storage better than older bias-ply designs, but they still age from heat, time, and environmental exposure.

Long stationary periods are especially hard on heavier crossovers and SUVs because the vehicle weight rests on a relatively small contact patch. If the vehicle will sit for an extended season, a clean indoor environment and occasional repositioning are worthwhile. Owners who store the vehicle on stands should still keep the tires protected from light and ozone so the sidewalls remain in better condition between drives.

For a 2017 BMW Trucks vehicle, tire age matters as much as tread depth. A common collector and specialty-vehicle rule of thumb is to begin evaluating tires closely once they reach about five to seven years of age and to treat around ten years as a serious replacement point regardless of mileage. The DOT date code on the sidewall remains the best quick reference for understanding a tire’s age.

That age-based approach is especially relevant for vehicles that are driven less often, because a tire can look acceptable at a glance yet still be aging internally. Heat cycles, storage conditions, curb damage, and underinflation can shorten service life well before the tread is worn out. If a 2017 BMW Trucks vehicle still carries older tires, age and condition deserve as much attention as brand or speed rating.

Tires on a 2017 BMW Trucks vehicle should be inspected before every drive and again before any longer highway outing. Check inflation, tread depth, shoulder wear, punctures, cracking, bulges, and any signs that the tire has been run low. On staggered BMW applications, inspect front and rear tires separately because the wear pattern and replacement timing may differ from axle to axle.

A more thorough inspection at regular service intervals is also worthwhile, especially on 19-, 20-, and 21-inch packages with lower sidewall heights. Catching irregular wear early can point to alignment issues, bent wheels, or suspension concerns before they become expensive problems. If the spare is present, inspect that tire too, since age and pressure neglect often show up there first.

Yes, the radial sizes used on 2017 BMW Trucks vehicles are suitable for highway use when the tire is the correct size, in sound condition, and inflated properly. Speed ratings in the available products include W and Y, which correspond to 168 mph and 186+ mph respectively, while some sizes also appear in performance-oriented configurations without a lower-speed limitation indicated in the basic fitment record. Those ratings exceed normal U.S. highway speeds by a wide margin.

Real-world safety still depends on more than the tire alone. Vehicle load, alignment, suspension condition, and whether the X5 or X6 is running the correct staggered combination all matter. For a 2017 BMW Trucks vehicle that sees regular road use, the best practice is to match the original size family, maintain inflation carefully, and avoid mixing incompatible front and rear fitments.

Inflation pressure on a 2017 BMW Trucks vehicle should follow the factory placard or owner’s manual first, because BMW sets pressure by model, axle load, and tire package. Some tire products in these sizes publish maximum load figures at 50 or 51 psi, including 1565 lbs at 50 psi for 225/45R19, 1709 lbs at 50 psi for 225/50R18 and 245/40R20, 1874 lbs at 50 psi for 245/45R19 and 275/35R20, 2039 lbs at 50 psi for 275/40R19, and 2094 at 50 psi for one 275/40R20 application.

Those numbers are tire capacity references, not a universal recommendation to inflate every 2017 BMW Trucks tire to that pressure. The correct everyday setting depends on the exact model, tire size, and whether the vehicle is carrying passengers or cargo. Check the door-jamb placard or manual, then confirm that your chosen tire’s load-and-pressure envelope supports that intended use.

Before a longer drive in a 2017 BMW Trucks vehicle, inspect every tire for cuts, punctures, sidewall bubbles, exposed cords, uneven wear, and proper inflation. Confirm that the front and rear sizes match the wheel positions actually on the vehicle, especially on X5 and X6 models where staggered fitments are common. Also look at valve stems, tread depth across the full width, and the condition and pressure of the spare if one is carried.

A long-drive check should also include the broader mechanical basics that matter on any BMW crossover or SUV: brakes, coolant, battery condition, and suspension feel. Tires are one part of that readiness check, but they are the part that immediately affects ride, steering response, and load carrying. Spending a few minutes on inspection before departure is far easier than diagnosing vibration or a roadside failure later.
