The 2018 Volvo V90 Cross Country blends long-roof wagon practicality with the raised stance and all-road character that made modern Volvo Cross Country models distinct from ordinary luxury wagons. It appeals to buyers who want a contemporary touring vehicle with a little more wheel-and-tire presence than a standard V90. Tire fitment centers on three radial sizes—235/55R18, 235/50R19, and 245/45R20—depending on the exact sub-model and wheel package. That creates meaningful choice not only in size, but also in brand, tire series, and sidewall treatment on certain 20-inch options. The key is confirming the exact sub-model and wheel diameter before comparing appearance, road-use priorities, and replacement style.
Which Tire Size Is Right for The 2018 Volvo V90 Cross Country
Three tire sizes apply to the 2018 Volvo V90 Cross Country, and they vary by sub-model and wheel diameter rather than by construction, since all are radial fitments. The first step is identifying the exact T5, T6, or T6 Ocean Race configuration and confirming whether the vehicle is on 18-inch, 19-inch, or 20-inch wheels before choosing among replacement tires.
The 235/50R19 size uses a 235-millimeter section width, a 50-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2018 Volvo V90 Cross Country, this is one of the core modern radial fitments and appears on both T5 and T6 applications. It sits in the middle of the model's wheel-size spread, making it a useful reference point for owners comparing factory-style replacement sizing. The practical choice here is not construction type, but confirming that the car actually has 19-inch wheels before selecting a tire in this size family.
The 235/55R18 code identifies a 235-millimeter-wide radial tire with a 55-series profile for an 18-inch wheel. For the 2018 Volvo V90 Cross Country, this size is tied to specific T5 configurations rather than the full model range. Its dimensions place it very close in overall height to the other primary fitments, but it still depends on the correct 18-inch wheel setup. This size is the right one to evaluate when the vehicle carries the smaller wheel package and the goal is staying with the proper factory-style fitment format.
The 245/45R20 size combines a 245-millimeter section width with a 45-series profile and radial construction on a 20-inch rim. On the 2018 Volvo V90 Cross Country, it is used on T6 and T6 Ocean Race configurations and is the size with the broadest visible product variety. Available choices include BFGoodrich, Nitto, and Pro-Trac options, along with Blackwall, Redline, and raised white letter sidewall treatments across several tire series. This is the size to confirm when the vehicle has the largest wheel package and appearance choice matters alongside basic fitment.
Sub-model fitment matters on the 2018 Volvo V90 Cross Country because tire size changes with the specific configuration and wheel package. Checking whether the vehicle is a T5, T6, or T6 Ocean Race is the quickest way to narrow the correct size before comparing tires.

2018 Volvo V90 Cross Country T5
The 2018 Volvo V90 Cross Country T5 uses two radial tire size paths, depending on whether the car is equipped with 18-inch or 19-inch wheels. That makes wheel confirmation especially important before selecting a replacement tire, since both sizes belong to the T5 but are not interchangeable without the matching rim diameter.
The 2018 Volvo V90 Cross Country T6 can be fitted with either the 19-inch radial size or the larger 20-inch radial setup. Tire selection starts with verifying the actual wheel diameter on the car, then comparing the available product choices in the matching size, especially if appearance or tire series is part of the decision.
The 2018 Volvo V90 Cross Country T6 Ocean Race uses the 20-inch radial fitment rather than sharing the full range of sizes found across the standard T5 and T6 lineup. That simplifies the size question, but still leaves room to compare brands and sidewall styles within the correct 245/45R20 category.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

These FAQs focus on the exact tire sizes used on the 2018 Volvo V90 Cross Country, how sub-model and wheel choice affect fitment, and what to consider when comparing available radial tires for road use and appearance.
Tire Size & Fitment
What tire size fits a 2018 Volvo V90 Cross Country?
The 2018 Volvo V90 Cross Country uses three primary radial tire sizes: 235/55R18, 235/50R19, and 245/45R20. The correct one depends on the exact sub-model and wheel package, not simply the model name alone. T5 configurations use 235/55R18 or 235/50R19, while T6 applications use 235/50R19 or 245/45R20, and the T6 Ocean Race uses 245/45R20.
That means the first thing to verify is the actual wheel diameter on the vehicle. Two V90 Cross Country trims can look similar while requiring different tires, so checking the placard, current tire sidewall, and wheel size before ordering helps avoid choosing the right size for the wrong wheel.
What size rim does a 2018 Volvo V90 Cross Country use?
A 2018 Volvo V90 Cross Country can use 18-inch, 19-inch, or 20-inch rims, depending on the tire size fitted to the vehicle. The 235/55R18 tire uses an 18-inch rim, the 235/50R19 uses a 19-inch rim, and the 245/45R20 uses a 20-inch rim. All of these are radial tire applications.
Rim diameter is the non-negotiable starting point because a tire must match the wheel's bead seat diameter exactly. Once that is confirmed, it is still wise to compare the wheel width and overall vehicle setup, especially if the car has been changed from its original wheel package at some point.
Why does the 2018 Volvo V90 Cross Country have more than one tire size?
More than one tire size appears on the 2018 Volvo V90 Cross Country because fitment varies by sub-model and wheel package. The T5 can use either an 18-inch or 19-inch setup, the T6 can use a 19-inch or 20-inch setup, and the T6 Ocean Race is tied to the 20-inch size. All three are primary radial fitments.
This is common on modern wagons and crossovers that were offered with different wheel designs and trim-specific equipment. The practical takeaway is simple: identify the exact trim and confirm the wheel diameter already on the car before comparing replacement tires, especially when buying for a used vehicle with uncertain wheel history.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2018 Volvo V90 Cross Country?
Start with the correct size and construction: 245/45R20 radial tires are used on certain 2018 Volvo V90 Cross Country T6 models and the T6 Ocean Race. Within that size, the available choices differ by brand, tire series, sidewall treatment, and some specification details such as stated rim-width range, load figure, and product weight.
The right comparison depends on how the vehicle is used and how it should look. A buyer focused on a clean modern presentation may prefer a Blackwall tire, while someone wanting more visual character may look at Redline or raised white letter options, then confirm wheel compatibility before making the final choice.
What sidewall styles are available for 2018 Volvo V90 Cross Country tires?
For the 2018 Volvo V90 Cross Country's available 245/45R20 product selection, sidewall choices include Blackwall, Redline, and RWL, which is raised white letter. Those treatments appear within radial tires in this size, giving owners different visual directions without changing the underlying wheel diameter requirement.
Sidewall style mainly affects appearance, so the decision comes after confirming the correct size for the car. A Blackwall keeps the look understated, while Redline or raised white letters make the tire more noticeable, and those style differences can matter on a wagon with large 20-inch wheels and visible wheel openings.
What brands offer tires for the 2018 Volvo V90 Cross Country?
Among the available 245/45R20 tires for the 2018 Volvo V90 Cross Country, brands include BFGoodrich, Nitto, and Pro-Trac. Those choices span several tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand alone should not be the only filter. It helps to compare the exact series, sidewall style, and wheel-compatibility details that matter to the vehicle's current setup, especially on 20-inch applications where both visual presentation and proper fit on the existing wheel should be part of the decision.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Volvo V90 Cross Country?
A period-style approach on a 2018 Volvo V90 Cross Country usually means keeping the correct factory-era sizing format for the exact wheel package already on the car. Since this model uses modern metric radial sizes, the appearance decision is less about vintage construction and more about staying with the proper 18-inch, 19-inch, or 20-inch tire size.
For owners who want a more distinctive look on 20-inch setups, sidewall treatment becomes the visible styling variable. Blackwall keeps the presentation closer to a contemporary OEM-style look, while Redline or raised white letter options create a more personalized appearance without changing the underlying radial fitment format.
How does tire construction affect the appearance of a restored 2018 Volvo V90 Cross Country?
On a 2018 Volvo V90 Cross Country, construction has less visual impact than it would on a vintage car because the primary fitments are already modern radial tires. The more noticeable appearance differences come from tire proportions, wheel diameter, and sidewall treatment, especially within the 245/45R20 size where several styling options are available.
A restoration-minded owner will usually get the most consistent look by matching the tire size to the wheel package the vehicle was built around. After that, choose a sidewall style that supports the intended presentation of the car, whether the goal is understated factory-era character or a more customized visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Volvo V90 Cross Country?
Yes, modifications can affect tire fitment on a 2018 Volvo V90 Cross Country even when the tire size itself is correct for the model range. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and body modifications can all influence how a 235/55R18, 235/50R19, or 245/45R20 tire sits in the wheel opening.
That is especially important on vehicles bought used, where the wheel setup may not match the original trim package. Checking clearance at the fender, strut, and steering range before mounting replacement tires helps prevent problems that would not appear on a stock vehicle using the same nominal size.
What should I inspect before driving a 2018 Volvo V90 Cross Country on new tires?
Before driving a 2018 Volvo V90 Cross Country on new tires, inspect the wheels for damage, confirm that the tire size matches the wheel diameter, and make sure inflation is set correctly for the vehicle's use. It is also worth looking over the suspension and alignment condition so the new tires are not immediately compromised.
A short check after installation can prevent bigger issues later. Watch for any rubbing at full steering lock, listen for unusual noise, and recheck pressure after the first drives, particularly if the car has sat for long periods or recently changed wheel packages between 18-inch, 19-inch, or 20-inch fitments.
How often should tires on a 2018 Volvo V90 Cross Country be inspected?
Tires on a 2018 Volvo V90 Cross Country should be inspected regularly, not only when tread looks worn. Look at pressure, tread wear pattern, sidewall condition, and any signs of cuts, bulges, punctures, or slow air loss. On a vehicle with multiple possible wheel packages, it also makes sense to confirm that all four tires match the intended fitment.
Routine checks matter even more on a vehicle that sees seasonal use or long parked periods. A quick inspection before a road trip, after storage, or anytime ride quality changes can catch aging or fitment problems early, especially on lower-profile 19-inch and 20-inch applications where wheel and tire condition are more visible.
