2018 Volvo Trucks marked a period when Volvo’s crossover lineup emphasized upscale design, all-weather usability, and a distinctly Scandinavian approach to family luxury. In this year, the make’s XC60 and XC90 covered two-row and three-row needs, but tire sizing was not uniform across the range. Seven tire sizes appear across two models, with 235/55R19 and 235/60R18 shared between both, while the 20-, 21-, and 22-inch fitments split by model and wheel package. For a buyer, the first step is confirming whether the vehicle is an XC60 or XC90, then matching the exact wheel diameter before narrowing down the right tire size and product style.
Which Tire Size Is Right for Your 2018 Volvo Trucks
2018 Volvo Trucks vehicles use seven tire sizes, and they vary by model rather than carrying across the full range. Since every size here is a radial, the real decision starts with confirming whether you have an XC60 or XC90 and then matching the correct wheel diameter. Understanding that distinction before choosing a product saves time and helps ensure the right match.
235/55R19 is a radial metric size with a 235-millimeter section width, a 55-series aspect ratio, and fitment for a 19-inch wheel. Product coverage is not present here, so brand, sidewall, tube, and speed-rating choices are handled once you move into the model or size-specific page. Because this size is shared by both the XC60 and XC90, it is one of the core 19-inch fitments across the 2018 Volvo Trucks range. Buyers should confirm the actual wheel diameter and the vehicle’s model-specific package before moving ahead.
Year(s): 2018|Fit(s): XC60|Construction: Radial|Rim: 20 in
255/45R20 is a radial metric size with a 255-millimeter section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. This XC60-specific size is available from BFGoodrich, Nitto, and Pro-Trac, with Blackwall and RWL sidewall styles and W-rated products up to 168 mph. It sits on an 8.0- to 9.5-inch rim where that range is stated, and some products in this size also carry load ratings such as 1819 pounds at 51 psi. This is the 20-inch XC60 choice when you want the tire size tied to that wheel package rather than one of the shared 18- or 19-inch fitments.
235/60R18 is a radial metric size with a 235-millimeter section width, a 60-series aspect ratio, and fitment for an 18-inch wheel. Product coverage is not present here, so sidewall style, tube status, and speed-rating details depend on the exact tire selected farther down the fitment path. Both the XC60 and XC90 use this size, making it a shared 18-inch option within the 2018 Volvo Trucks lineup. Confirming the wheel diameter first is the key step before comparing individual tires.
255/40R21 is a radial metric size with a 255-millimeter section width, a 40-series aspect ratio, and fitment for a 21-inch wheel. Product coverage is not present here, so brand and sidewall details depend on the specific tire selected for this size. This fitment is specific to the XC60 rather than universal across 2018 Volvo Trucks models, so it should be matched carefully to the correct wheel package. Buyers considering this size should treat model identification and wheel diameter confirmation as the first priority.
275/35R22 is a radial metric size with a 275-millimeter section width, a 35-series aspect ratio, and fitment for a 22-inch wheel. Product coverage is not present here, so sidewall style, speed-rating, and tube details depend on the individual tire chosen. This size is specific to the XC90 and reflects the largest wheel diameter used in the 2018 Volvo Trucks range. It is the one to focus on only if your XC90 is equipped with the corresponding 22-inch wheels.
275/45R20 is a radial metric size with a 275-millimeter section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. Product coverage is not present here, so brand, speed-rating, and sidewall-style choices are determined at the size-specific product level. This is an XC90-only fitment, so it should not be assumed to interchange with every 20-inch Volvo crossover wheel from the same year. The practical step is verifying that your XC90 carries the 20-inch package designed for this wider section width.
275/40R21 is a radial metric size with a 275-millimeter section width, a 40-series aspect ratio, and fitment for a 21-inch wheel. Product coverage is not present here, so sidewall options and speed ratings depend on the exact tire selected. This size belongs specifically to the XC90 and is not shared with the XC60, even though both models use 21-inch fitments elsewhere in the lineup. Matching the model and wheel diameter is essential before comparing any tire in this size.
Two models are covered for 2018 Volvo Trucks. Tire size varies by model, so knowing only the year and make is not enough; XC60 and XC90 share some fitments, but each also carries its own wheel-package-specific sizes. Select your model below to narrow the fitment history and see the tires that apply to that vehicle.
2018 Volvo Trucks XC60
The 2018 Volvo Trucks XC60 is the midsize member of Volvo’s crossover family, blending a more athletic footprint with the same clean design language that defined the brand in this era. Its tires mount on 18-, 19-, 20-, or 21-inch wheels depending on configuration, so wheel diameter is a key part of identifying the correct fitment.
The 2018 Volvo Trucks XC90 served as Volvo’s larger three-row crossover, aimed at buyers who wanted more passenger and cargo space without leaving the premium SUV segment. Its tires mount on 18-, 19-, 20-, 21-, or 22-inch wheels, and that broader span makes model-and-wheel-package confirmation especially important.
Four products are available across one of the seven tire sizes used on 2018 Volvo Trucks vehicles. The 255/45R20 offers four radial choices from BFGoodrich, Nitto, and Pro-Trac with Blackwall and RWL sidewall styles. Confirm your exact size and wheel diameter before selecting a tire.
These FAQs cover how 2018 Volvo Trucks tire sizes split between XC60 and XC90, what the metric size codes mean, how wheel diameter affects selection, and what to watch for when maintaining a modern collector-friendly Volvo crossover.
Size Basics & Fitment
What tire sizes fit 2018 Volvo Trucks vehicles?
2018 Volvo Trucks vehicles use seven radial tire sizes across two models: 235/60R18 and 235/55R19 fit both the XC60 and XC90; 255/45R20 and 255/40R21 fit the XC60; 275/45R20, 275/40R21, and 275/35R22 fit the XC90. Those sizes mount on 18-, 19-, 20-, 21-, and 22-inch wheels, so there is no single year-and-make-wide wheel diameter to assume.
That means the right starting point is the model and wheel package, not just the badge on the hood. If your vehicle still wears its original wheel diameter, matching the tire size is usually straightforward. If wheels have been changed, verify the actual diameter and compare the current size marking on the sidewall before choosing a replacement.
What does 235/55R19 mean on a 2018 Volvo Trucks tire?
On a 2018 Volvo Trucks tire, 235/55R19 means the tire is 235 millimeters wide, the sidewall height is 55 percent of that width, the R indicates radial construction, and the tire fits a 19-inch wheel. In this year and make, 235/55R19 is a shared size used on both the XC60 and XC90.
That code matters because each part of it affects fitment. The 19-inch wheel diameter must match exactly, while the width and aspect ratio influence the tire’s overall proportions. If your XC60 or XC90 currently wears 19-inch wheels, this size is one of the common places to start, but it should still be confirmed against the sidewall already on the vehicle.
Do all 2018 Volvo Trucks models use the same tire size?
No, 2018 Volvo Trucks models do not all use the same tire size. The XC60 and XC90 share 235/60R18 and 235/55R19, but the XC60 alone uses 255/45R20 and 255/40R21, while the XC90 alone uses 275/45R20, 275/40R21, and 275/35R22. Every size in this range is radial, but the dimensions and wheel diameters vary by model and package.
That split is important because a same-year Volvo crossover can still need a very different replacement tire depending on whether it is the midsize or three-row model. If you are comparing tires for a family fleet or shopping for a recently purchased vehicle, identify the exact model first and then confirm the wheel diameter before narrowing the tire options.
Buying the Right Tire
What sidewall styles are available for 2018 Volvo Trucks tires?
Sidewall style coverage is currently visible in the 255/45R20 size, where 2018 Volvo Trucks XC60 owners can choose Blackwall or raised white letter sidewalls. BFGoodrich and Nitto options in that size use Blackwall styling, while Pro-Trac offers an RWL version. The other Volvo sizes in this year and make require moving into the specific size and model path to compare sidewall presentation.
For most late-model Volvo applications, Blackwall styling tends to align more naturally with the understated factory appearance and luxury-crossover character. Raised white letters bring a more assertive aftermarket look that some owners prefer on customized builds. Sidewall choice will not change wheel diameter or base fitment, but it can noticeably change how the vehicle presents.
What brands make tires for 2018 Volvo Trucks vehicles?
BFGoodrich, Nitto, and Pro-Trac currently cover the 255/45R20 size used on the 2018 Volvo Trucks XC60. BFGoodrich appears in both the g-Force COMP-2 A/S and g-Force Sport COMP-2 lines, Nitto covers the size with the NT555 G2, and Pro-Trac offers the Street Pro III in a raised white letter configuration.
That mix gives XC60 owners a choice between established performance-oriented nameplates and a more style-driven sidewall option. Brand selection should come after the core fitment questions are settled, especially because the broader 2018 Volvo Trucks range uses several different wheel diameters. Start with the exact size on your vehicle, then compare the available brands within that size.
What is the difference between BFGoodrich g-Force COMP-2 A/S and BFGoodrich g-Force Sport COMP-2 for the 2018 Volvo Trucks?
For the 2018 Volvo Trucks XC60 in 255/45R20, both BFGoodrich options share the same basic size, a 20-inch rim diameter, an 8.0- to 9.5-inch rim width range, Blackwall styling, a 101W service description, and a weight of 32 pounds. The g-Force Sport COMP-2 also carries a published load figure of 1,819 pounds at 51 psi, while the g-Force COMP-2 A/S is presented as the all-season version within the same family.
The practical difference is less about fitment and more about the tire line you want within that exact XC60 size. Since both share the same wheel and width requirements, the decision comes down to the specific series character and details shown on the sidewall. Owners should compare the tire’s intended seasonal use and tread category alongside the vehicle’s driving habits.
Fitting & Setup
What rim width do 2018 Volvo Trucks tires require?
Rim width guidance is currently visible for one 2018 Volvo Trucks size: 255/45R20, used on the XC60, fits an 8.0- to 9.5-inch wheel in the products that publish a width range. The rest of the year-and-make sizes still need to be matched by their exact product specifications once you move from the year-and-make view into the specific size and tire choice.
Rim width matters because the same wheel diameter does not automatically mean the same wheel width. A 20-inch XC60 fitment and a 20-inch XC90 fitment are not interchangeable by diameter alone. Before replacing tires, confirm the wheel’s actual width stamp or manufacturer spec so the tire’s approved range and the wheel match properly.
Do 2018 Volvo Trucks tires require inner tubes?
The 2018 Volvo Trucks sizes here are all modern radial applications, and the published 255/45R20 products do not carry tube-type markings. That points buyers toward contemporary tubeless-style fitment in this part of the range rather than the tube-type construction often associated with vintage bias-ply tires.
Even so, the safest approach is to check the sidewall marking on the specific tire you choose and the condition of the wheel it will mount on. Tube use is not normally the question on a late-model Volvo crossover; wheel integrity, valve stem condition, and correct installation are usually the more important setup details before the tire goes into service.
Maintenance, Storage & Longevity
How should I store a 2018 Volvo Trucks when the tires are fitted?
A 2018 Volvo Trucks should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. If the vehicle will sit for an extended period, moving it occasionally helps prevent prolonged flat spotting and keeps one section of the tread from carrying the full load for months at a time.
Late-model radial tires generally tolerate storage better than older bias-ply designs, but they still age when exposed to heat, UV, and ozone. If long-term storage is planned, many owners also use stands or slightly overinflate within safe limits recommended by the manufacturer to reduce casing stress. A brief visual inspection before the vehicle returns to use is always worthwhile.
How long do tires on a 2018 Volvo Trucks typically last?
Tires on a 2018 Volvo Trucks should be judged by age as much as by tread depth, especially on lower-mileage vehicles. A common collector and enthusiast rule is to start evaluating tires closely around five to seven years of age and to treat around ten years as a serious replacement point, regardless of how much tread remains. The DOT date code on the sidewall gives the week and year of manufacture.
That matters because many premium crossovers see uneven use: long parked periods, short trips, and occasional highway travel. A tire that still looks serviceable at a glance can harden or crack with time. Owners should use the date code, visual condition, and overall driving plan together rather than relying on mileage alone.
How often should tires on a 2018 Volvo Trucks be inspected?
Tires on a 2018 Volvo Trucks deserve a quick inspection before every drive and a more thorough inspection before any longer trip. Check inflation pressure, tread wear, cuts, punctures, bulges, curb damage, and sidewall cracking, and look for any sign that one tire is wearing differently from the others. Uneven wear can point to alignment, suspension, or inflation issues rather than a tire defect alone.
That regular habit is especially important on a heavier crossover that may carry passengers, cargo, or spend time at highway speeds. A one-minute walk-around often catches a problem early enough to avoid a ruined tire or a roadside issue. If the vehicle has been sitting, inspect all four tires and the spare before setting off.
Safety & Road Use
Are 2018 Volvo Trucks tires safe for highway driving?
2018 Volvo Trucks tires in the covered range are modern radial sizes, and the visible 255/45R20 products carry W speed ratings, which correspond to a 168 mph ceiling. That far exceeds normal U.S. highway use, but safe road performance still depends on the tire being the correct size, in good condition, properly inflated, and mounted on the right wheel. The vehicle’s own weight, alignment, suspension condition, and brake condition matter at least as much as the speed symbol on the sidewall.
For most owners, the takeaway is that a properly selected modern radial tire is well suited to highway driving in a late-model Volvo crossover. The real risk comes from using the wrong size, running aged-out tires, or ignoring wear and damage. Safety starts with fitment and condition long before anyone approaches the tire’s rated speed capability.
What inflation pressure should I use for 2018 Volvo Trucks tires?
Inflation pressure for a 2018 Volvo Trucks should follow the vehicle manufacturer’s door-jamb or owner’s-manual recommendation first, because that target is set around the vehicle’s weight distribution and intended load. One published 255/45R20 tire in this range shows a maximum load of 1,819 pounds at 51 psi, but that is a tire capacity figure rather than a blanket operating pressure for every 2018 Volvo Trucks application or every tire size.
The practical rule is not to transfer a pressure number from one size to another, or from one product line to another. Use the vehicle placard for normal service and compare it with the tire maker’s information for the exact tire you select. If the vehicle is carrying unusual cargo or seeing sustained high-speed travel, reassess pressure with the maker’s guidance.
What should I check before taking a 2018 Volvo Trucks on a longer drive?
Before taking a 2018 Volvo Trucks on a longer drive, inspect all four tires for cracking, cuts, punctures, bulges, exposed cords, and uneven tread wear. Confirm cold inflation pressures, make sure the valve stems are intact, and check the spare tire as well. If the vehicle has been parked for a while, watch for vibration from temporary flat spotting during the first miles.
That tire check should be part of a broader pre-trip review that suits the age and complexity of a modern premium crossover. Brake condition, fluid levels, battery health, and warning lights all deserve attention alongside the tires. A careful inspection at home is far easier than dealing with a tire or wheel issue once the trip is already underway.
