The 2017 Ford Focus spans a wide range of personalities, from efficient commuter trims to the all-electric Focus Electric and the high-output ST and RS hatchbacks. That variety matters at tire time, because this Focus uses six different primary radial tire sizes across its sub-model lineup, with rim diameters ranging from 15 to 19 inches. Some versions stay with practical blackwall performance radials, while others open the door to appearance-driven choices such as redline or wide whitewall styling in 215/55R16. The right decision starts with confirming the exact trim and wheel diameter, then choosing a tire that matches how the car is being kept, driven, and presented.
Which Tire Size Is Right for The 2017 Ford Focus
The 2017 Ford Focus uses six primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All of them are radial tires, but they span 15-, 16-, 17-, 18-, and 19-inch rims, so confirming the trim and the actual wheels on the car comes first. Once that is settled, the real comparison is between the available brands, tire series, sidewall styles, and intended use within the correct size.
225/50R17 is a metric radial size with a 225-millimeter section width, a 50-series aspect ratio, and fitment for a 17-inch rim. On the 2017 Ford Focus, this size is used on the Focus Electric and keeps the buyer in modern radial construction rather than a vintage-style format. Available choices in this size include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. It is a useful size to evaluate when the car already has the correct 17-inch wheel setup and the goal is to balance everyday road use with a more performance-oriented tire selection.
235/35R19 is a metric radial size that pairs a 235-millimeter width with a lower 35-series profile on a 19-inch rim. On the 2017 Ford Focus, this size belongs to the RS, so it should be treated as a trim-specific fitment rather than a general Focus size. Product choices here are blackwall radials from Nitto and BFGoodrich, including the NT555 G2 and g-Force Phenom T/A. This size makes the most sense when the car retains its 19-inch wheel package and the buyer wants to compare available performance-focused tire lines within the proper low-profile fitment.
195/65R15 is a metric radial size with a 195-millimeter section width, a 65-series profile, and a 15-inch rim diameter. On the 2017 Ford Focus, this is the primary size for the S, making it one of the more straightforward trim-specific fitments in the lineup. The size format itself points to a practical modern radial setup centered on standard wheel diameter and everyday drivability rather than an appearance-focused or ultra-low-profile presentation. It is the size to confirm when an S model still carries its original wheel diameter, especially before comparing any replacement tires against wheel width, clearance, and current vehicle setup.
215/50R17 is a metric radial with a 215-millimeter section width, a 50-series aspect ratio, and a 17-inch rim diameter. On the 2017 Ford Focus, this size appears on the SE, SEL, and Titanium, so it is one of the more common 17-inch fitments in the range. Available products are blackwall BFGoodrich options across several g-Force series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size is worth focusing on when the car is one of the 17-inch trims and the choice comes down to comparing tire series and road-use character within the proper fitment.
215/55R16 is a metric radial size combining a 215-millimeter width with a 55-series profile on a 16-inch rim. On the 2017 Ford Focus, it appears on certain SE configurations and the SE with SFE Package, so it should be confirmed by trim and wheel diameter before selection. This size has one of the broadest appearance spreads in the lineup, with blackwall BFGoodrich options as well as American Classic radial choices in redline and wide whitewall form. It is especially relevant when the owner wants to stay with the correct 16-inch fitment but tailor the car toward either modern road use or a more distinctive visual presentation.
235/40R18 is a metric radial size with a 235-millimeter section width, a 40-series profile, and fitment for an 18-inch rim. On the 2017 Ford Focus, this size is used on the ST and on the Titanium with Handling Package, so it is tied to specific higher-spec wheel packages. Buyers can compare blackwall radials from BFGoodrich and Nitto, with available series including g-Force Comp 2 AS, g-Force Sport Comp 2, NT555 G2, and g-Force Phenom T/A. It is the right size to evaluate when the car has the proper 18-inch wheels and the goal is choosing among several performance-oriented modern radial options.
Tire fitment on the 2017 Ford Focus varies significantly by sub-model, so trim identification matters before comparing tires. Several versions share similar wheel diameters, but the lineup as a whole spans multiple sizes and performance levels, making wheel and trim confirmation the first step.

2017 Ford Focus Electric
The 2017 Ford Focus Electric uses a 17-inch radial tire fitment centered around 225/50R17. Tire selection here is mainly about staying with the proper wheel diameter and then comparing blackwall radial options by brand and tire series.
The 2017 Ford Focus RS uses a 19-inch radial setup with 235/35R19. That makes wheel diameter and low-profile fitment especially important, and the next decision becomes comparing the available blackwall performance-oriented tire choices in that exact size.
The 2017 Ford Focus S uses a 15-inch radial tire size, 195/65R15. For this sub-model, the main task is confirming that the car still has its proper 15-inch wheel package before choosing a replacement tire in the correct size format.
The 2017 Ford Focus SE can use either a 16-inch or 17-inch radial tire size, so trim alone is not enough without checking the wheels on the car. Tire selection starts with confirming whether the SE has the 215/55R16 or 215/50R17 setup, then comparing products within that exact fitment.
The 2017 Ford Focus SE (SFE Pkg.) uses the 215/55R16 radial size. That makes the choice more straightforward than a standard SE, with the real comparison shifting toward blackwall versus appearance-oriented sidewall treatments in the correct 16-inch fitment.
The 2017 Ford Focus SEL uses the 215/50R17 radial size. Once the 17-inch wheel setup is confirmed, buyers can focus on comparing the available BFGoodrich tire series rather than sorting through multiple primary fitments.
The 2017 Ford Focus ST uses the 235/40R18 radial size on an 18-inch wheel. Tire selection here centers on choosing among several blackwall performance-style options while keeping the correct rim diameter and overall fitment in view.
The 2017 Ford Focus Titanium uses the 215/50R17 radial size. With the primary fitment narrowed to one 17-inch size, the buyer can concentrate on tire series and road-use priorities rather than sorting through multiple wheel diameters.
The 2017 Ford Focus Titanium w/Handling Pkg. uses the 235/40R18 radial size. That puts it in the same general size family as the ST, making correct 18-inch wheel confirmation the first step before comparing available blackwall radial performance options.
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.

Depending on fitment, buyers can compare g-Force, NT555 G2, and Asymmetrical Tread series within the correct wheel diameter.
These 2017 Ford Focus tire FAQs focus on the details that matter most once the exact trim is known: size, wheel diameter, sub-model differences, available tire styles, and the checks to make before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2017 Ford Focus?
A 2017 Ford Focus does not use one universal tire size across the whole model range. Depending on sub-model, the primary radial sizes are 195/65R15, 215/55R16, 215/50R17, 225/50R17, 235/40R18, and 235/35R19.
The correct choice starts with identifying the exact trim and confirming the wheels currently on the car. An S, SE, ST, RS, Electric, or Titanium can require a different size, and a standard SE may use more than one factory wheel diameter, so checking the sidewall and wheel before ordering is important.
What size rim does a 2017 Ford Focus use?
The 2017 Ford Focus uses several rim diameters depending on sub-model and tire size. The lineup includes 15-, 16-, 17-, 18-, and 19-inch wheel fitments, matched to the corresponding tire sizes used across the Focus range.
Rim diameter is the first fitment detail to verify because a tire must match the wheel exactly. A 17-inch tire will not mount on an 18-inch wheel, and a Focus that has had wheels changed over time may no longer match the original trim-based setup, so checking the actual wheel on the car is the safest first step.
Why does the 2017 Ford Focus have more than one tire size?
The 2017 Ford Focus covers several distinct sub-models, including economy-oriented trims, the Electric, the ST, and the RS, and those versions do not share one common wheel and tire package. That is why the range spans from 195/65R15 up to 235/35R19.
This means tire shopping for a Focus is really trim-specific rather than model-wide. A buyer should confirm the exact sub-model and also check whether the car still has its intended wheel diameter, especially on SE and Titanium variants where different wheel packages can change the correct tire size.
Choosing the Right Tire
What should I consider when choosing a 2017 Ford Focus tire?
Start with the correct size for the exact 2017 Ford Focus sub-model, then compare tires within that fitment by construction, brand, tire series, and sidewall style. All primary Focus fitments here are radial, but the available products vary from straightforward blackwall performance tires to redline and wide whitewall options in 215/55R16.
The best comparison points depend on how the car is used and presented. A daily-driven SE, an appearance-focused 16-inch setup, and a performance-oriented ST or RS do not call for the same tire character, so wheel diameter, rim-width compatibility, load figures, and visual style should all be reviewed before making a final choice.
What sidewall styles are available for 2017 Ford Focus tires?
Sidewall style depends on the tire size. Blackwall is the most common treatment across the 2017 Ford Focus product range, while 215/55R16 also includes redline and wide whitewall radial options from American Classic.
That gives 16-inch Focus applications a different appearance path than the rest of the lineup. Buyers keeping a standard modern look can stay with blackwall tires, while someone building a more customized visual presentation may want to compare the redline or wide whitewall choices and confirm that the car uses the correct 215/55R16 fitment.
What brands offer tires for the 2017 Ford Focus?
Available 2017 Ford Focus tire brands include BFGoodrich, Nitto, and American Classic, depending on the size. BFGoodrich appears across several 16-, 17-, 18-, and 19-inch applications, Nitto is offered in selected 17-, 18-, and 19-inch sizes, and American Classic appears in 215/55R16.
Brand choice should come after the correct size is confirmed. Once the trim and wheel diameter are settled, the useful comparison becomes which series and sidewall treatments are available in that exact fitment, rather than assuming every brand shown for one Focus tire size also applies to the rest of the model range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Ford Focus?
Yes. Wheel changes, altered suspension height, and body or brake modifications can all affect tire fitment on a 2017 Ford Focus, even when the car began with one of the correct factory tire sizes. That matters even more on lower-profile 18- and 19-inch setups where clearance margins are typically tighter.
A Focus with aftermarket wheels should be checked for actual rim diameter, width, and clearance at full steering lock and suspension movement before new tires are chosen. The same applies if springs, struts, or alignment settings have changed, because a size that matches the trim on paper may not suit the car's current wheel and suspension setup.
What should I inspect before driving a 2017 Ford Focus on new tires?
Before putting a 2017 Ford Focus back into regular road use, inspect the wheels for damage, confirm the tire size matches the trim and rim diameter, and check that each tire is seated and inflated correctly. It also helps to look over the suspension and steering for worn parts that could affect tire wear or tracking.
A short visual inspection should continue after installation. Look for rubbing marks, uneven clearance, air loss, or any sign that the tire is too close to suspension or body components, especially if the car has non-original wheels or a lower-profile fitment such as 235/40R18 or 235/35R19.
How should tires on a 2017 Ford Focus be maintained?
Tires on a 2017 Ford Focus should be checked regularly for pressure, tread wear, cuts, sidewall damage, and any signs of slow air loss. Even on a later vehicle like this, infrequently driven cars can develop age-related issues long before the tread appears worn out.
Good maintenance also means watching for uneven wear that may point to alignment or suspension problems. Cars with larger wheels and lower-profile tires deserve extra attention because impact damage and shoulder wear can appear sooner, so periodic inspections and prompt correction of vibration, pull, or pressure loss are worth making part of routine ownership.
