The 2017 Buick Cascada arrived as a modern four-seat convertible with a touring-minded character that set it apart from more aggressive open-top cars of its era. Its blend of relaxed road manners, contemporary proportions, and upscale Buick branding makes tire choice especially important, because the wheel-and-tire package has a big influence on ride quality and appearance. Every 2017 Buick Cascada sub-model uses a 245/40R20 radial tire on a 20-inch rim. That single fitment still leaves room to choose among blackwall, raised white letter, and redline styles across several performance-oriented radial series. The key is matching the correct size first, then selecting the look and driving character that suit the car.
Which Tire Size Is Right for The 2017 Buick Cascada
The 2017 Buick Cascada uses one primary tire size: 245/40R20, a radial fitment for a 20-inch rim. That same size is shared across Base, Premium, and Sport Touring models, so the main decision is not size selection but choosing the right tire within that fitment based on sidewall style, tire series, and the kind of road use or appearance you want.
In 245/40R20, the 245 identifies the nominal section width in millimeters, the 40 is the aspect ratio, the R indicates radial construction, and the 20 is the wheel diameter in inches. On the 2017 Buick Cascada, this modern radial size supports the car's contemporary 20-inch wheel fitment and is used across the covered sub-model range. Available choices include blackwall options from BFGoodrich, Nitto, and Pro-Trac, along with Pro-Trac Street Pro III versions in raised white letter and redline form. That gives you room to keep a restrained late-model look or add a more custom visual treatment while staying in the correct size.
Tire fitment is straightforward across the 2017 Buick Cascada range, because the covered sub-models share the same primary tire size. Checking the exact sub-model still helps confirm that the car remains on its original wheel setup before comparing tire series or sidewall style.

2017 Buick Cascada Base
The 2017 Buick Cascada Base uses the same 245/40R20 radial fitment found across the model range. That keeps tire selection focused on choosing the right product style, brand, and sidewall treatment rather than sorting through multiple primary sizes.
The 2017 Buick Cascada Premium also uses 245/40R20 radial tires on a 20-inch rim. With fitment staying consistent, the decision comes down to the appearance and product characteristics that best match a stock presentation or a more customized look.
The 2017 Buick Cascada Sport Touring shares the 245/40R20 radial tire size with the other covered trims. That makes it easier to compare blackwall, raised white letter, and redline options while keeping the correct overall fitment starting point.
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.

Common questions for the 2017 Buick Cascada usually center on its single 245/40R20 fitment, 20-inch rim compatibility, sidewall-style choices, and what to inspect before road use on a modern convertible that may have seen seasonal or low-mileage service.
Tire Size & Fitment
What tire size fits a 2017 Buick Cascada?
The 2017 Buick Cascada uses a 245/40R20 radial tire. That fitment applies across the covered Base, Premium, and Sport Touring sub-models, so the primary size question is unusually simple for this vehicle.
With only one primary size in play, the real next step is confirming that the car is still on its intended 20-inch wheel setup. If a previous owner changed wheels or altered the suspension, verify wheel width, tire clearance, and overall condition before choosing among the available 245/40R20 tire options.
What size rim does a 2017 Buick Cascada use?
The 2017 Buick Cascada uses a 20-inch rim with its 245/40R20 tire fitment. That 20-inch diameter is consistent across the covered sub-models, which keeps the fitment picture straightforward.
Rim diameter is only one part of the match, so it is still worth checking actual wheel width before mounting replacement tires. Some available 245/40R20 products include specific rim-width guidance, and that becomes especially important if the car has aftermarket wheels or a stance change that affects clearance.
Do all 2017 Buick Cascada sub-models use the same tire size?
Yes. The 2017 Buick Cascada Base, Premium, and Sport Touring all use the same 245/40R20 radial tire size. There is no split in primary tire size among those covered sub-models.
That consistency means you can focus more on tire style and product character than on decoding trim-level fitment differences. It is still smart to inspect the actual car before ordering, since wheel swaps, damaged rims, or prior modifications can change what should be checked for clearance and mounting compatibility.
Choosing the Right Tire
What should I consider when choosing a 245/40R20 tire for a 2017 Buick Cascada?
Start with the correct 245/40R20 size and confirm that the tire matches the car's 20-inch wheel setup. From there, compare radial tire series, sidewall style, and any available rim-width guidance so the tire suits both the vehicle and the way it is used.
Some owners want a clean late-model blackwall appearance, while others prefer a more distinctive raised white letter or redline presentation. It also helps to compare details such as product weight and load-related specifications where available, especially if the car sees regular road use rather than occasional fair-weather cruising.
What sidewall styles are available for 2017 Buick Cascada tires?
The available 245/40R20 choices for the 2017 Buick Cascada include blackwall, raised white letter, and redline sidewall styles. That gives the car a broader visual range than many late-model fitments that are limited to plain blackwall tires.
Blackwall works well for a restrained factory-inspired presentation, while raised white letter and redline options create a more custom or performance-themed look. Sidewall style does not change the need to stay with the correct size, so appearance should be chosen after confirming wheel compatibility and the kind of driving the car will actually see.
What brands offer tires for the 2017 Buick Cascada?
Tires for the 2017 Buick Cascada are available from BFGoodrich, Nitto, and Pro-Trac in the 245/40R20 size. Those options span several radial tire series rather than a single product style.
Brand choice is best treated as one part of a broader comparison instead of the only decision. Looking at tire series, sidewall treatment, rim-width guidance, and the overall presentation you want from the car usually gives a better result than choosing only by name, especially when several products share the same basic fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Buick Cascada?
A period-style approach for a 2017 Buick Cascada still begins with the correct 245/40R20 radial size, since this is a modern convertible with a contemporary low-profile fitment. Within that size, a blackwall tire usually keeps the presentation closest to a restrained original-era look.
Raised white letter or redline versions can shift the car toward a more personalized appearance without changing the primary fitment size. If exact originality matters at a show level, compare the tire's visual details against Buick sales literature, period photos, or marque-specific references before making the final choice.
Which sidewall style suits a period-style 2017 Buick Cascada?
For a period-style 2017 Buick Cascada, blackwall is generally the most understated choice among the available sidewall treatments. It complements the car's modern touring-convertible character without drawing attention away from the wheels and body lines.
Redline and raised white letter versions introduce a stronger custom accent, which may appeal more to an owner shaping a personalized street look than a stock-leaning presentation. The best match depends on whether the goal is subtle authenticity-inspired appearance or a deliberate visual update within the same 245/40R20 fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Buick Cascada?
Yes. A 2017 Buick Cascada may start with a straightforward 245/40R20 fitment, but aftermarket wheels, suspension changes, or body-height adjustments can affect how that size sits in the wheelwell. Even when the size code stays the same, the overall setup can change the fitment result.
Wheel width, offset, and steering clearance deserve close attention on any modified car. A Cascada with lowered suspension or replacement wheels should be checked for fender, inner-liner, and suspension clearance before mounting new tires, since the correct size on paper does not override changes made to the actual vehicle.
What should I inspect before driving a 2017 Buick Cascada on new tires?
Before driving a 2017 Buick Cascada on new tires, inspect the wheels for damage, confirm the tires are properly seated and inflated, and make sure there is no rubbing at full steering lock. It is also worth checking for uneven wear clues that may point to alignment or suspension issues.
A convertible that sees seasonal use can hide problems that are easy to miss in the garage, including aging valve stems, weak shocks, or dried suspension bushings. A short, careful test drive followed by another visual check helps confirm that the 245/40R20 tires are operating cleanly on the car's actual wheel setup.
How often should tires on a 2017 Buick Cascada be inspected?
Tires on a 2017 Buick Cascada should be inspected regularly, not just when tread looks low. Collector-minded or fair-weather cars especially benefit from routine checks for cracking, punctures, bulges, irregular wear, and pressure loss because low annual mileage does not prevent tire aging.
Monthly visual checks are a sensible habit, with a closer inspection before longer drives or after the car has been stored. Paying attention to inflation pressure, tread condition, and any vibration or pull on the road can help catch problems early and protect both the tires and the 20-inch wheel package.
