The 2016 Buick Cascada arrived as a modern Buick convertible aimed at drivers who wanted open-air cruising with contemporary road manners rather than vintage compromise. Its combination of upscale styling and everyday usability makes tire choice more about preserving the car’s balance of appearance, ride, and response than sorting through multiple factory-era fitments. The 2016 Buick Cascada uses a 245/40R20 radial tire on a 20-inch rim, and both Base and Premium models share that same size. Available choices include blackwall, raised white letter, and redline sidewall treatments across several radial series. That makes it important to match the tire not just to size, but to the car’s look and intended use.
Which Tire Size Is Right for The 2016 Buick Cascada
The 2016 Buick Cascada uses one primary tire size: 245/40R20, a radial fitment on a 20-inch rim. Base and Premium models share that same sizing, so the main decision is not which size fits the car, but which tire best matches the way the Cascada is driven, the sidewall style you want, and the product characteristics that matter most on a modern convertible.
A 245/40R20 size uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2016 Buick Cascada, this is a modern low-profile radial fitment that supports the car’s contemporary wheel-and-tire proportions and keeps tire selection centered on handling feel, appearance, and wheel compatibility. Available choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall styles represented in the size. This is the size to evaluate when you want to keep the Cascada on its intended 20-inch setup while comparing tire series and visual character.
Tire fitment is straightforward across the covered 2016 Buick Cascada range because both sub-models use the same 245/40R20 radial size. Checking the exact trim still helps confirm that the wheel setup has not been changed from the original 20-inch format before choosing among the available tire styles and series.

The 2016 Buick Cascada Premium also uses 245/40R20 radial tires on a 20-inch wheel format. For this trim, the decision centers on choosing the right tire character and appearance while confirming the car still carries the expected wheel 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:

Tire questions for the 2016 Buick Cascada usually come down to confirming the 245/40R20 fitment, understanding the 20-inch wheel requirement, and choosing among available radial, sidewall, and brand options. The FAQs below also cover maintenance, modifications, and road-use checks.
Tire Size & Fitment
What tire size fits a 2016 Buick Cascada?
The 2016 Buick Cascada uses a 245/40R20 radial tire size. Both the Base and Premium sub-models use that same primary fitment, so there is no split between trims in the covered lineup.
That makes the buying decision more about selecting the right tire within the 245/40R20 size than figuring out which size belongs on the car. It is still smart to confirm that the Cascada still has its 20-inch wheels, especially if it was purchased used or has had aftermarket wheel changes.
What size rim does a 2016 Buick Cascada use?
The 2016 Buick Cascada uses a 20-inch rim with its 245/40R20 tire size. That 20-inch diameter is central to the fitment, since the final number in the tire size must match the wheel diameter.
Rim diameter is only part of the picture, so wheel width should also be checked when comparing products. Several 245/40R20 choices in this fitment are intended for wheels in roughly the 8- to 9.5-inch range, which matters if the car has replacement wheels that differ from the stock setup.
Do all 2016 Buick Cascada sub-models use the same tire size?
Yes. The covered 2016 Buick Cascada sub-models share the same 245/40R20 radial tire size. That includes both the Base and Premium versions, so trim level does not change the primary tire size here.
Shared sizing simplifies replacement, but it does not eliminate the need to inspect the actual wheel-and-tire package on the car. A used Cascada may have aftermarket wheels, replacement tires in a slightly different marked size, or suspension changes that should be understood before selecting a new set.
Choosing the Right Tire
What should I consider when choosing a 245/40R20 tire for a 2016 Buick Cascada?
Start with the correct 245/40R20 size and 20-inch wheel requirement, then compare the available radial tire series, sidewall styles, and wheel-width compatibility. For the 2016 Buick Cascada, the core decision is choosing a tire that suits the car’s intended use and visual style without stepping outside the correct fitment.
A Cascada driven mainly for cruising may lead a buyer toward one appearance, while a car used more regularly may put greater emphasis on product character and specification details. Looking at rim-width suitability, sidewall treatment, and any stated load information helps narrow the field without treating all 245/40R20 tires as identical.
What sidewall styles are available for 2016 Buick Cascada tires?
Available 245/40R20 tires for the 2016 Buick Cascada include blackwall, raised white letter, and redline sidewall styles. Each keeps the same basic size fitment but changes the visual presentation of the car in a noticeable way.
Blackwall suits a clean modern appearance, while raised white letter and redline options create a more expressive look. Sidewall style does not replace the need to confirm the proper size, wheel compatibility, and general suitability, but it can be one of the easiest ways to tailor the Cascada’s stance and personality.
What brands offer tires for the 2016 Buick Cascada?
The 2016 Buick Cascada’s 245/40R20 fitment is available from BFGoodrich, Nitto, and Pro-Trac. Those choices span several radial tire series, giving the size a useful mix of product character and appearance options.
Brand alone should not be the only deciding factor. It helps to compare each tire’s series, sidewall treatment, wheel-width suitability, and any available load specification so the selection matches the car’s setup and the way it is actually driven rather than relying on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Buick Cascada?
A period-style approach on a 2016 Buick Cascada still begins with the correct 245/40R20 radial size, since this is a modern convertible with a contemporary low-profile tire format. The visual choice then comes from the available tire series and sidewall treatments rather than from older bias-ply or tall-sidewall styling cues.
For a restrained appearance, a blackwall tire keeps the look clean and current. A buyer who wants the car to stand out more may consider raised white letter or redline options, but the wheel size, tire dimensions, and overall presentation should still stay in balance with the Cascada’s original design language.
How does tire construction affect the appearance of a restored 2016 Buick Cascada?
On a 2016 Buick Cascada, construction is less about choosing between vintage formats and more about staying with the proper modern radial presentation. The covered fitment is radial only, so the appearance difference comes more from tire profile and sidewall styling than from switching between construction types.
That makes visual consistency especially important on a car with large 20-inch wheels and relatively short sidewalls. Keeping the correct 245/40R20 size preserves the intended proportions, while details such as blackwall, raised white letter, or redline sidewalls allow the finished look to lean subtle or more expressive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Buick Cascada?
Yes. Wheel, suspension, and ride-height changes can affect tire fitment on a 2016 Buick Cascada even when the tire size stays close to 245/40R20. Aftermarket wheels may alter width or offset, which can change how the tire sits relative to the fender, suspension, and steering components.
A modified car should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension movement before replacement tires are chosen. That matters especially on a low-profile 20-inch setup, where small changes in wheel specification can create rubbing or appearance issues more quickly.
What should I inspect before driving a 2016 Buick Cascada on new tires?
Before driving a 2016 Buick Cascada on new tires, inspect wheel condition, valve stems, tire pressure, and overall installation quality. The tires should be the correct 245/40R20 size, seated properly on the 20-inch wheels, and free from visible mounting damage, cuts, or bead issues.
A short initial road check helps confirm that the car tracks properly and that there is no rubbing, vibration, or unusual steering behavior. It also helps to recheck inflation and inspect for any signs of air loss after the first drives, especially if the Cascada has sat for long periods or recently received wheel service.
How often should tires on a 2016 Buick Cascada be inspected?
Tires on a 2016 Buick Cascada should be inspected regularly, not just when tread looks worn. A modern convertible that sees seasonal or low-mileage use can still develop age-related issues such as sidewall cracking, flat spotting, air loss, or damage from curb contact and road impacts.
Monthly pressure checks and routine visual inspections are a sensible baseline, with extra attention before longer drives. Looking for uneven wear, bulges, cuts, and changes in ride or steering feel can catch problems early, and that is particularly worthwhile on 245/40R20 low-profile tires where wheel and tire damage can be easier to miss.
