The 2014 Cadillac ELR arrived as Cadillac’s sleek, coupe-bodied luxury plug-in, blending dramatic Art and Science styling with a modern grand-touring character that set it apart from more conventional electrified cars of its era. Buyers looking at an ELR today are usually balancing appearance, road manners, and proper fitment on a distinctly contemporary 20-inch wheel package. This model uses a 245/40R20 radial tire, so the main decision is less about finding the right size and more about choosing the right version of that size. Available choices include blackwall, raised white letter, and redline presentations across several performance-oriented radial series. That makes wheel compatibility, intended use, and visual style the key points to settle before selecting tires.
Which Tire Size Is Right for The 2014 Cadillac ELR
The 2014 Cadillac ELR uses one primary tire size: 245/40R20, and it is a radial fitment on a 20-inch rim. The ELR Base uses that same size, so the main decision is not which primary size applies, but which 245/40R20 tire best matches the car’s wheel setup, driving use, and preferred sidewall appearance.
A 245/40R20 tire uses a nominal section width of 245 millimeters, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2014 Cadillac ELR, that modern low-profile radial format suits the car’s contemporary wheel package and keeps selection focused on performance-oriented street tires rather than vintage-style construction choices. Within this size, available options include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments. Choosing among them comes down to confirming wheel width, comparing tire-series character, and deciding whether the ELR should keep a clean modern look or a more distinctive sidewall presentation.
Fitment is straightforward for the covered 2014 Cadillac ELR sub-models. The key point is simply confirming that the car is the ELR Base and still retains the correct 20-inch wheel setup before choosing among the available 245/40R20 radial options.

2014 Cadillac ELR Base
The 2014 Cadillac ELR Base uses the same 245/40R20 radial tire size as the model core fitment. That keeps selection centered on wheel-width compatibility, tire-series preference, and whether a blackwall, raised white letter, or redline sidewall best suits the car’s intended look.
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 2014 Cadillac ELR?
The 2014 Cadillac ELR uses a 245/40R20 radial tire. That size combines a 245-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter, which gives the ELR its modern low-profile fitment and keeps tire selection within contemporary radial offerings.
Because the ELR uses one primary size, the real fitment check is confirming that the car still has the proper 20-inch wheels and suitable wheel width for the tire being considered. If the car has aftermarket wheels or any suspension changes, compare the tire and wheel setup carefully before installation.
What size rim does a 2014 Cadillac ELR use?
The 2014 Cadillac ELR uses a 20-inch rim diameter with its 245/40R20 tire fitment. That 20-inch diameter is central to the tire size itself, since the final number in 245/40R20 identifies the wheel diameter the tire is built to mount on.
Rim diameter is only part of the fitment picture, so wheel width still matters when comparing specific tires. Some available 245/40R20 products are intended for wheels in the 8- to 9.5-inch range, making it worthwhile to confirm the actual wheel dimensions before choosing among the available radial options.
Does the 2014 Cadillac ELR Base use the same tire size?
Yes. The 2014 Cadillac ELR Base uses the same 245/40R20 radial tire size. That makes sub-model fitment straightforward, since there is not a separate primary tire size to sort through for the covered ELR Base configuration.
Even with shared fitment, it is still smart to verify the wheel setup on the individual car before replacing tires. An ELR that has been modified with different wheels, altered ride height, or cosmetic changes may need additional clearance and wheel-width checks before a new 245/40R20 tire is selected.
Choosing the Right Tire
What should I consider when choosing a 245/40R20 tire for a 2014 Cadillac ELR?
Start with the correct size, which is 245/40R20, and make sure the tire matches the ELR’s 20-inch wheel setup. From there, compare construction details, tire series, sidewall style, and any stated wheel-width requirements so the tire suits both the car and the way it will be used.
Appearance can matter as much as fitment on an ELR, especially when deciding between blackwall, raised white letter, and redline sidewalls. It also helps to compare useful product details such as weight and load information where available, then match those factors to your wheel dimensions and overall driving expectations.
What sidewall styles are available for 2014 Cadillac ELR tires?
The available 245/40R20 tires for a 2014 Cadillac ELR include blackwall, raised white letter, and redline sidewall styles. Blackwall keeps the most understated modern appearance, while raised white letter and redline options add a more expressive visual treatment without changing the basic size category.
Sidewall style does not override fitment, so the first priority remains choosing the correct 245/40R20 tire for the wheel. Once size and wheel compatibility are confirmed, sidewall treatment becomes a useful way to shape the ELR’s presentation, whether the goal is a clean contemporary look or a more custom-oriented appearance.
What brands offer tires for the 2014 Cadillac ELR?
The 2014 Cadillac ELR has 245/40R20 tire options from BFGoodrich, Nitto, and Pro-Trac. Those choices span several radial tire series, including BFGoodrich g-Force lines, Nitto’s NT555 G2, and Pro-Trac Street Pro III, giving the ELR owner more than one brand and style direction to consider.
Brand choice should be evaluated alongside the specific tire series, sidewall treatment, and wheel-width compatibility rather than in isolation. Two tires may share the same basic size but present the car differently, so it helps to compare the details of each 245/40R20 option against the ELR’s wheel setup and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Cadillac ELR?
A period-style approach for a 2014 Cadillac ELR still begins with the correct 245/40R20 radial size, since this is already a modern low-profile fitment. From there, the visual choice is mostly about tire series and sidewall treatment rather than bias-ply versus radial or vintage sizing conventions.
Blackwall options tend to preserve the cleanest contemporary luxury appearance, while raised white letter or redline versions can give the ELR a more personalized presentation. If exact showroom-era appearance matters, compare the car’s existing look with period photos, original sales material, or marque-specific references before settling on a sidewall style.
How does tire construction affect the appearance of a restored 2014 Cadillac ELR?
On a 2014 Cadillac ELR, tire construction is not a bias-ply-versus-radial restoration question because the primary fitment is already radial. Visually, the bigger difference comes from the tire’s profile, tread presentation, and sidewall style within the correct 245/40R20 size rather than from a change in tire construction type.
That means appearance decisions are more closely tied to whether the car should look understated, factory-inspired, or more customized. A blackwall radial generally maintains a cleaner contemporary look, while raised white letter or redline treatments create a stronger visual statement without changing the fundamental ELR fitment format.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Cadillac ELR?
Yes. A 2014 Cadillac ELR may use the correct 245/40R20 tire size from the factory-style setup, but aftermarket wheels, wheel-offset changes, altered ride height, or suspension modifications can all change how that size sits in the car. Even small changes can affect clearance on a low-profile 20-inch application.
Checking the actual wheel width and overall wheel position is important before mounting new tires on a modified car. Steering clearance, inner suspension clearance, and fender clearance should all be reviewed, especially if the ELR has been lowered or fitted with custom wheels that differ from the original-style setup.
What should I inspect before driving a 2014 Cadillac ELR on new tires?
Before driving a 2014 Cadillac ELR on new tires, inspect the wheels for damage, confirm the tires are properly mounted and inflated, and make sure the 245/40R20 fitment clears the suspension and bodywork through steering and suspension travel. Lug hardware should also be tightened to the proper specification.
A careful walkaround after installation is worthwhile, especially on a car that may sit for long periods. Look for uneven ride height, rubbing marks, or signs of air loss after the first drive, then recheck pressures and overall tire condition so the ELR is road-ready before regular use or a longer trip.
How should 245/40R20 tires on a collector 2014 Cadillac ELR be maintained?
245/40R20 tires on a collector-driven 2014 Cadillac ELR should be inspected regularly for air loss, tread wear, cuts, bulges, and sidewall cracking. Because many specialty or low-use vehicles spend long periods parked, tire condition matters just as much as tread depth, especially before the car returns to regular road use.
Keeping the ELR stored away from prolonged sunlight, heat, moisture, and ozone sources can help preserve tire condition over time. It also helps to maintain proper inflation, move the car periodically, and inspect the tires before any longer drive so age-related issues are caught early rather than discovered on the road.
