The 2018 Volvo V90 blends modern Scandinavian wagon design with the long-roof practicality that has defined Volvo for decades. In this generation, the V90 leans more toward premium touring than utility-only duty, so tire choice affects both stance and day-to-day road manners. This model uses radial tires in two primary sizes, 255/40R19 and 255/35R20, both with the same overall diameter but different wheel diameters. That opens the door to different series, brands, and sidewall treatments, including Blackwall, raised white letter, and Redline options. The main decision is confirming which wheel package is on the car, then choosing the tire look and product character that best matches its use.
Which Tire Size Is Right for The 2018 Volvo V90
The 2018 Volvo V90 uses two primary tire sizes, and the first thing to confirm is wheel diameter. Both 255/40R19 and 255/35R20 are radial fitments used across the covered V90 sub-models, with matching overall diameter but different rim sizes. Once the wheel size is confirmed, the real choice becomes comparing available tire series, sidewall styles, and product specifications within the correct size.
Fit(s): T5 Inscription, T5 R-Design, T6 Inscription, and T6 R-Design
Construction: Radial|Rim: 20 in
255/35R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2018 Volvo V90, this size supports the 20-inch wheel setup while keeping the overall diameter aligned with the 19-inch alternative. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with Blackwall, raised white letter, and Redline sidewall treatments across several series. This size is the one to evaluate if the car is already equipped with 20-inch wheels and the goal is to stay with that wheel package.
Fit(s): T5 Inscription, T5 R-Design, T6 Inscription, and T6 R-Design
Construction: Radial|Rim: 19 in
255/40R19 is a metric radial size where 255 is the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 19 indicates the rim diameter in inches. For the 2018 Volvo V90, it is the companion fitment to the 20-inch package, carrying the same overall diameter on a 19-inch wheel. Product choices include BFGoodrich and Pro-Trac offerings in multiple series, with Blackwall, raised white letter, and Redline sidewall styles available. This is the size to focus on when the car has 19-inch wheels and the goal is to compare appearance and specification differences within that setup.
Tire fitment is straightforward across the covered 2018 Volvo V90 sub-models because each one uses the same two primary sizes. Checking the exact sub-model still matters, but the bigger fitment step is confirming whether the car is on 19-inch or 20-inch wheels before selecting a tire.

2018 Volvo V90 T5 Inscription
The 2018 Volvo V90 T5 Inscription uses the same two radial tire sizes found across the covered V90 range, so the fitment question centers on wheel diameter rather than a unique sub-model-only tire. Tire selection then comes down to matching the car's 19-inch or 20-inch wheel setup and choosing among the available series and sidewall styles.
The 2018 Volvo V90 T5 R-Design shares the same radial tire fitment pattern as the other covered V90 sub-models. That means the practical next step is confirming the installed wheel package, then comparing product choices within the correct size for sidewall appearance, rim-width compatibility, and overall tire character.
The 2018 Volvo V90 T6 Inscription follows the same two-size radial fitment as the rest of the covered V90 lineup. Choosing tires for this sub-model is mainly about verifying whether the car wears 19-inch or 20-inch wheels, then selecting the right series and sidewall treatment within that confirmed size.
The 2018 Volvo V90 T6 R-Design also uses the same pair of radial tire sizes as the other covered sub-models. The important check is wheel diameter, since both sizes share the same overall diameter but mount on different rims, and that determines which available tire options can be considered.
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.

Tire Size & Fitment
What tire size fits a 2018 Volvo V90?
The 2018 Volvo V90 uses two primary tire sizes: 255/35R20 and 255/40R19. Both are radial sizes, and both appear across the covered T5 Inscription, T5 R-Design, T6 Inscription, and T6 R-Design sub-models.
The key is not choosing by trim alone, but by the wheel package actually on the car. Since one size fits a 20-inch rim and the other fits a 19-inch rim, the quickest way to avoid a mismatch is to confirm the current wheel diameter before comparing brands, sidewall styles, or tire series.
What size rim does a 2018 Volvo V90 use?
A 2018 Volvo V90 can use either a 19-inch or 20-inch rim, depending on which primary tire size is on the car. The 255/40R19 size mounts on a 19-inch wheel, while the 255/35R20 size mounts on a 20-inch wheel.
Because both sizes share the same overall diameter, a quick visual estimate can be misleading. Checking the wheel itself or reading the existing tire sidewall is a better starting point, especially if the car has had a wheel change, a replacement set installed, or a seasonal swap at some point in its service life.
Do all 2018 Volvo V90 sub-models use the same tire size?
The covered 2018 Volvo V90 sub-models all share the same two tire sizes rather than having unique trim-specific fitments. T5 Inscription, T5 R-Design, T6 Inscription, and T6 R-Design can each use 255/35R20 or 255/40R19 radial tires.
That makes sub-model identification less important than wheel confirmation. A buyer looking at a V90 should first verify whether the car is sitting on 19-inch or 20-inch wheels, then choose among the correct tire options in that size instead of assuming one fitment applies to every individual car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Volvo V90?
Start with the correct size for the wheel package already on the car: 255/40R19 for 19-inch rims or 255/35R20 for 20-inch rims. From there, compare construction, rim-width compatibility where stated, tire series, sidewall style, and any load figures that appear within the options being considered.
The 2018 Volvo V90 gives more than one visual and product-character choice within each size, so the decision is not purely dimensional. A Blackwall tire keeps a more understated look, while raised white letter or Redline sidewalls change the presentation noticeably, and those style preferences should be balanced against the actual wheel setup and intended use.
What sidewall styles are available for 2018 Volvo V90 tires?
Available sidewall styles for the 2018 Volvo V90 include Blackwall, RWL, and Redline, depending on the tire size and product selected. Those sidewall treatments appear within both 255/35R20 and 255/40R19 fitments, giving the car a more conventional or more stylized presentation.
Sidewall style does not replace the basic fitment checks. The first step is still confirming the correct tire size for the car's wheel diameter, then narrowing the options by appearance. Buyers who want a cleaner late-model look often stay with Blackwall, while RWL or Redline adds a more custom visual statement without changing the primary size.
What brands offer tires for the 2018 Volvo V90?
Tires for the 2018 Volvo V90 are available from BFGoodrich, Nitto, and Pro-Trac in the covered sizes. Depending on whether the car uses 255/35R20 or 255/40R19, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III.
Brand choice should come after the fitment basics are settled. Once the wheel diameter is confirmed, compare the available products by series, sidewall treatment, rim-width specification where shown, and any stated load information, rather than selecting a tire by brand name alone and trying to make it fit afterward.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Volvo V90?
A period-style approach on a 2018 Volvo V90 usually starts with keeping the correct modern radial size for the wheel package already on the car, then choosing a tire whose visual character suits the wagon's clean, understated design. For most buyers, that points first toward Blackwall options in either 255/40R19 or 255/35R20.
The V90 is a modern premium wagon rather than a chrome-era restoration project, so appearance choices tend to be subtle. A buyer chasing a restrained factory-inspired look should focus on the proper size, a compatible rim specification, and a sidewall treatment that does not overpower the car's shape unless a more custom presentation is part of the goal.
How does tire construction affect the appearance of a restored 2018 Volvo V90?
For the 2018 Volvo V90, the primary fitment is radial, so the construction question is less about changing the car's historic character and more about choosing the right visual treatment within a modern tire format. In practice, appearance is shaped more by sidewall style and tire series than by a bias-ply-versus-radial decision.
A Blackwall tire tends to preserve the V90's cleaner contemporary look, while RWL or Redline adds more visual emphasis. Buyers interested in a restoration-oriented result should keep the original wheel diameter and overall presentation in mind, then use marque references or original sales material if exact appearance details matter for the car being preserved.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Volvo V90?
Yes. A 2018 Volvo V90 may use either 255/40R19 or 255/35R20, and modifications such as aftermarket wheels, changes in wheel width, altered offset, lowering, or suspension changes can affect which tire setup works correctly on the car.
Even when the size code looks right, a modified car can have different clearance needs at the fender, strut, or steering range. The safest approach is to verify the actual wheel diameter on the car first, then check width, offset, and visible clearance before selecting a replacement tire in the same nominal size.
What should I inspect before driving a 2018 Volvo V90 on new tires?
Before putting a 2018 Volvo V90 back into regular road use on new tires, inspect the wheel size, mounting direction if applicable, valve stems, and inflation pressure, then look over the suspension and alignment condition if there were any wear issues with the previous tires.
A short test drive should also confirm that there is no rubbing at full steering lock or over suspension movement. It is smart to recheck pressure after the first drives and keep an eye on the tire shoulders and sidewalls, since early signs of contact or alignment trouble usually appear there first.
How often should tires on a 2018 Volvo V90 be inspected?
Tires on a 2018 Volvo V90 should be checked regularly, not only by mileage but also by time and condition. A practical routine is to inspect them during pressure checks, before longer trips, and any time the car begins to show vibration, pull, uneven wear, or visible sidewall changes.
Modern radial tires can still develop issues that are easy to miss on a casual walkaround. Look for cracking, bulges, cuts, punctures, and unusual tread wear, and make sure the tire size still matches the wheel package on the car if a previous owner changed wheels or installed a different seasonal setup.
