The 2013 Volvo C70 blends Swedish grand-touring character with retractable-hardtop convertible packaging, giving it a different mission than many traditional vintage or muscle-era tire searches. On this exact car, tire selection centers on two radial sizes, 235/45R17 and 235/40R18, so the first step is confirming which wheel diameter is on the vehicle. From there, the choice shifts to comparing performance-oriented blackwall options across BFGoodrich and Nitto tire lines. Owners replacing worn tires on a stock C70 or a car with changed wheels should keep the focus on the correct size, wheel compatibility, and the kind of road feel they want from a modern radial setup.
Which Tire Size Is Right for The 2013 Volvo C70
The 2013 Volvo C70 uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from one tire construction to another. Both fitments are radial, but one is built for a 17-inch rim and the other for an 18-inch rim, so identifying the wheel size on the car is the first and most important step before comparing tire choices.
A 235/40R18 tire uses a 235-millimeter nominal section width, a 40-series aspect ratio, radial construction, and an 18-inch rim. On the 2013 Volvo C70, this size points to a lower-profile modern radial fitment that keeps the tire and wheel package tied to 18-inch wheels. Available choices include blackwall performance tires from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the right one to evaluate when the car is already equipped with 18-inch wheels and the goal is staying within that wheel format.
A 235/45R17 tire carries the same 235-millimeter nominal width but uses a 45-series profile on a 17-inch rim. For the 2013 Volvo C70, this is also a radial fitment, but it is tied to a different wheel diameter and should not be confused with the 18-inch setup. Product choices in this size include blackwall tires from BFGoodrich and Nitto, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2. This size deserves attention when the car has 17-inch wheels and the buyer wants to compare available radial designs within that wheel package.
Sub-model fitment is straightforward here, but wheel choice still matters because the covered C70 configuration uses two tire sizes. Checking the exact sub-model helps confirm that the car falls within this fitment, then the decision comes back to whether it is riding on 17-inch or 18-inch wheels.

2013 Volvo C70 T5
The 2013 Volvo C70 T5 uses radial tire fitments in both 235/45R17 and 235/40R18, so the main distinction is the wheel diameter installed on the car. Tire selection then becomes a matter of matching the existing wheel setup and comparing the available blackwall performance tire lines in the correct size.
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 2013 Volvo C70?
The 2013 Volvo C70 uses two primary tire sizes: 235/45R17 and 235/40R18. Both are radial fitments, and both apply to the C70 T5, so the correct choice depends on which wheel diameter is actually on the car rather than a difference in tire construction.
That makes wheel confirmation the first step before replacing tires. A 17-inch wheel takes the 235/45R17 size, while an 18-inch wheel takes the 235/40R18 size. If the car has aftermarket wheels or a changed wheel-and-tire package, check the wheel diameter and width carefully before assuming one of the two factory-style fitments still applies.
What size rim does a 2013 Volvo C70 use?
A 2013 Volvo C70 can use either a 17-inch or an 18-inch rim, depending on the tire size installed. The 235/45R17 fitment pairs with a 17-inch rim, while the 235/40R18 fitment pairs with an 18-inch rim.
Rim diameter needs to match the tire exactly, so a quick sidewall check on the current tires is an easy starting point. It also helps to verify wheel width before selecting among available products, since the radial options in these sizes have their own rim-width ranges and should be matched to the actual wheel on the vehicle.
Why does the 2013 Volvo C70 have more than one tire size?
The 2013 Volvo C70 has more than one tire size because it was fitted with two different wheel diameters: 17 inches and 18 inches. That creates two valid radial tire fitments, 235/45R17 and 235/40R18, rather than one universal size for every car.
In practical terms, the tire decision starts with the wheels currently mounted on the vehicle. Cars that remain stock usually make this easy, but a used C70 may have had wheels swapped at some point. Matching the tire to the wheel diameter comes first, and then the buyer can compare brand, tire series, and other product details within the correct size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Volvo C70?
Start with the correct size for the wheel on the car: 235/45R17 for 17-inch wheels or 235/40R18 for 18-inch wheels. Since both fitments are radial, the next decision is comparing the available tire lines by factors such as rim-width compatibility, load figures where shown, tire series, and the kind of driving the car typically sees.
The 2013 Volvo C70 is a modern convertible, so owners often care about a balanced mix of road manners, appearance, and correct wheel fitment. Looking closely at the tire series can help separate all-season and sport-oriented choices, while checking wheel width keeps the search grounded in a setup that suits the tire being considered.
What sidewall styles are available for 2013 Volvo C70 tires?
The available tires for the 2013 Volvo C70 are blackwall radials in both 235/40R18 and 235/45R17. There are no alternate whitewall, redline, or raised white letter sidewall treatments in the current fitments shown here, so the visual presentation stays clean and modern.
That keeps the decision focused more on tire line and wheel compatibility than on sidewall appearance. For many C70 owners, that suits the car’s late-model touring character well. It also means the main comparison points are series differences, rim-width specifications, and whether the tire matches the wheel diameter already installed on the car.
What brands offer tires for the 2013 Volvo C70?
BFGoodrich and Nitto both offer tires for the 2013 Volvo C70 in the applicable 17-inch and 18-inch sizes. BFGoodrich appears in several g-Force lines, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, while Nitto is available in the NT555 G2 series.
Brand alone should not be the only deciding factor. A better approach is to compare the exact tire series available in the correct size for the car, then review wheel-width compatibility and other usable product details such as load figures and overall tire character. That keeps the selection tied to the wheel package and intended use of the C70.
Restoration & Appearance
Does correct tire fitment matter for a 2013 Volvo C70 restoration or refurbishment?
Correct tire fitment still matters on a 2013 Volvo C70, even though this is a newer collector-era convertible rather than a traditional antique or muscle car. Using the proper 235/45R17 or 235/40R18 radial size preserves the intended relationship between the wheel diameter, tire profile, and the car’s overall stance.
That is especially relevant on a refurbishment where the goal is to keep the car looking coherent rather than visibly mismatched. Before buying tires, verify whether the car is wearing its 17-inch or 18-inch wheel setup, then choose a tire series that supports the appearance and road-use character you want without drifting into an unrelated size.
How does tire choice affect the appearance of a 2013 Volvo C70?
Tire choice affects the appearance of a 2013 Volvo C70 mainly through profile and wheel relationship rather than through sidewall decoration. The two proper sizes, 235/45R17 and 235/40R18, both use blackwall radial construction, so the visual difference comes from whether the car is set up around a 17-inch or 18-inch wheel.
A C70 on the correct size tends to look proportionate, while an off-size tire can change the balance between wheel and sidewall in a way that looks out of place. Keeping the right size for the installed wheels is the first appearance step, and selecting among the available tire lines becomes a secondary styling and use decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Volvo C70?
Yes, modifications can affect tire fitment on a 2013 Volvo C70. The car already uses two different factory-style wheel diameters, so aftermarket wheels, altered offsets, suspension changes, or body modifications can change which tire size works correctly and how much clearance is available around the fenders and steering components.
That is why a modified C70 should be measured, not assumed. Check the actual wheel diameter and width first, then confirm there is enough room at full steering lock and through suspension travel. A tire that matches the sidewall marking on paper still needs to suit the car’s real-world wheel setup and available clearance.
What should I inspect before driving a 2013 Volvo C70 on new tires?
Before driving a 2013 Volvo C70 on new tires, inspect the wheel size, wheel condition, valve stems, and basic tire seating, then make sure the tires match the correct 17-inch or 18-inch fitment. It also helps to look over alignment-related wear issues so the new tires do not start life on a car with an existing suspension or steering problem.
A short initial road test is a smart follow-up. Pay attention to vibration, pulling, rubbing, or any sign that the tire is not clearing properly. Rechecking inflation pressure after installation and watching for early air loss can catch small issues quickly, especially on a convertible that may not see daily use year-round.
How often should tires on a 2013 Volvo C70 be inspected?
Tires on a 2013 Volvo C70 should be inspected regularly, not just when tread looks low. A modern convertible that sees seasonal or occasional use can go long stretches between major miles, so age, pressure loss, cuts, cracking, and irregular wear can matter just as much as simple tread depth.
Monthly pressure checks and routine visual inspections are a sensible habit, with closer attention before longer drives or after the car has been stored. Looking at both sidewalls, the tread surface, and the inner shoulder area can reveal problems early. That matters whether the C70 runs 235/45R17 tires or the lower-profile 235/40R18 setup.
