The 2014 Acura TSX sits at the end of Acura’s compact sport sedan era, blending everyday refinement with the sharper road manners that made the model appealing to drivers who wanted more involvement than a typical midsize sedan. It remains a practical modern enthusiast car, especially when wheel and trim differences are respected during tire replacement. Tire fitment centers on two radial sizes: 225/50R17 for Base and Special Edition models, and 235/45R18 for the V6. Available choices stay performance-oriented, with blackwall options from BFGoodrich and Nitto across several g-Force series. The key is matching the exact sub-model and wheel diameter first, then comparing tire character, rim-width compatibility, and intended use.
Which Tire Size Is Right for The 2014 Acura TSX
The 2014 Acura TSX uses two primary tire sizes, and the right one depends on the specific sub-model and wheel diameter. Base and Special Edition cars use a 17-inch setup with 225/50R17 tires, while the V6 uses a 235/45R18 tire on an 18-inch rim. Before comparing brands or tire series, confirm whether the car is a Base, Special Edition, or V6 and verify the wheel size currently on the vehicle.
In 235/45R18, the 235 is the nominal section width in millimeters, 45 is the aspect ratio, R means radial construction, and 18 identifies the rim diameter in inches. This size belongs to the 18-inch-wheel setup used on the 2014 Acura TSX V6, so it should be treated as a sub-model-specific fitment rather than a universal TSX size. Product choices are blackwall radial performance tires from BFGoodrich, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. It is the correct size to evaluate when the car is a V6 and still carries its 18-inch wheel package.
Tire fitment for the 2014 Acura TSX is not the same across every sub-model. Base and Special Edition models share one radial size, while the V6 moves to a different size on a larger wheel, so confirming the exact trim matters before selecting a tire.

2014 Acura TSX Base
The 2014 Acura TSX Base uses the 225/50R17 radial tire size. That keeps replacement straightforward, with the main decision shifting to brand, tire series, and whether the current 17-inch wheels remain original to the car.
The 2014 Acura TSX Special Edition also uses the 225/50R17 radial tire size. Selection comes down to comparing the available blackwall performance options and confirming that the car still carries its 17-inch wheel setup.
The 2014 Acura TSX V6 uses the larger 235/45R18 radial tire size. That makes wheel diameter the first confirmation point, after which the choice is between the available 18-inch blackwall performance tire series.
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.
Best 2014 Acura TSX Tires for Sale
Available 2014 Acura TSX tire choices focus on modern blackwall radial performance tires in 225/50R17 and 235/45R18. Buyers can compare BFGoodrich and Nitto options by tire series, rim-width compatibility, weight, and load capacity where stated.
These FAQs focus on the exact tire sizes used on the 2014 Acura TSX, how fitment changes by sub-model, and what to compare when choosing between the available radial performance tire options.
Tire Size & Fitment
What tire size fits a 2014 Acura TSX?
The 2014 Acura TSX uses two tire sizes depending on sub-model. Base and Special Edition models use 225/50R17 radial tires, while the TSX V6 uses 235/45R18 radial tires. Both are modern metric radial sizes, but they are tied to different wheel diameters and should not be treated as interchangeable across the full TSX range.
The first step is confirming whether the car is a Base, Special Edition, or V6, then checking the wheel diameter actually on the vehicle. A TSX with replacement wheels or a previous tire change may no longer match its original setup, so verifying both the trim and the current rim size avoids ordering the wrong tire.
What size rim does a 2014 Acura TSX use?
A 2014 Acura TSX uses either a 17-inch or 18-inch rim, depending on sub-model. The Base and Special Edition use 17-inch rims with 225/50R17 tires, and the V6 uses 18-inch rims with 235/45R18 tires. The tire size itself confirms the intended rim diameter, with the final number in the size showing the wheel size in inches.
Wheel diameter needs to be confirmed before comparing tire choices because a 17-inch tire cannot mount on an 18-inch wheel, and the reverse is also true. It also helps to check wheel width when selecting among products, since the available tires in these sizes are designed around specific rim-width ranges.
Do all 2014 Acura TSX sub-models use the same tire size?
No, all 2014 Acura TSX sub-models do not use the same tire size. The Base and Special Edition share the 225/50R17 size, but the V6 uses 235/45R18. That means the TSX lineup has two distinct fitment paths, each tied to a different wheel diameter and sub-model configuration.
This matters because tire selection starts with identifying the exact trim, not just the year and model name. When a car has been modified with different wheels, the safest approach is to verify the sidewall size already on the vehicle and measure the wheel diameter so the next set matches the actual setup.
Choosing the Right Tire
What should I consider when choosing a 2014 Acura TSX tire?
Start with the correct size for the car’s sub-model: 225/50R17 for Base and Special Edition, or 235/45R18 for the V6. From there, compare radial construction details such as tire series, rim-width compatibility, weight, and load capacity where those specifications are stated. On this TSX, the available choices are performance-oriented blackwall tires rather than whitewall or vintage-style options.
The right choice depends on how the car is used and whether it still has its original wheel setup. A daily-driven TSX may call for a different tire character than a fair-weather car, but the size and wheel diameter still come first. Checking the current wheels, alignment condition, and any uneven wear will also help narrow the selection.
What sidewall styles are available for 2014 Acura TSX tires?
The available tires for the 2014 Acura TSX are blackwall radials in both 225/50R17 and 235/45R18. That keeps the look contemporary and performance-focused, which suits the TSX’s modern sport sedan character. There are no alternate whitewall, redline, or raised white letter sidewall treatments in the currently available options for these fitments.
Because the sidewall presentation is consistent, the main visual differences come from the tire series and overall tread design rather than decorative sidewall styling. Buyers who care about appearance should still compare how the tires look on 17-inch versus 18-inch wheels, since wheel diameter changes the car’s stance as much as the tire itself.
What brands offer tires for the 2014 Acura TSX?
BFGoodrich and Nitto offer tires for the 2014 Acura TSX within the applicable sizes. In 225/50R17, choices include BFGoodrich g-Force series options and the Nitto NT555 G2. In 235/45R18, the available selections are BFGoodrich tires across several g-Force series, including Comp 2 AS, Sport Comp 2, and Phenom T/A.
Brand choice should be weighed alongside the exact tire series, since series names often signal differences in intended character within the same size. Instead of choosing only by brand, compare the tire that matches the car’s sub-model, the wheel width, and the way the TSX is driven, especially if it sees regular highway use or more spirited road driving.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Acura TSX?
A period-style 2014 Acura TSX is best approached by keeping the correct modern radial size for the specific sub-model and retaining the proper wheel diameter. That means 225/50R17 for Base and Special Edition cars or 235/45R18 for the V6. Since the TSX is a modern sport sedan, a contemporary blackwall radial appearance aligns more naturally with the vehicle than a decorative vintage-style presentation.
Appearance still depends on preserving the overall stance and proportion Acura intended for each trim. A TSX with aftermarket wheels can change that look quickly, so owners focused on restoration-minded presentation should confirm the wheel size now on the car and compare replacement tires that maintain the right profile for the sub-model.
Does correct tire fitment matter for a 2014 Acura TSX restoration?
Yes, correct tire fitment matters on a 2014 Acura TSX restoration because size and wheel diameter are part of the car’s visual balance as well as its road behavior. Using 225/50R17 on Base and Special Edition models and 235/45R18 on the V6 preserves the intended relationship between tire sidewall, wheel size, and trim-specific stance.
Restoration-minded owners should focus first on matching the proper sub-model fitment and then selecting a tire series that suits the finished look of the car. Exact originality questions about wheel design or delivery configuration are best checked against Acura-specific literature, window sticker records, or marque-focused reference material for the individual vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Acura TSX?
Yes, modifications can affect tire fitment on a 2014 Acura TSX even when the tire size looks close on paper. Aftermarket wheels may change width or offset, and suspension changes can alter fender and steering clearance. That matters on both TSX fitments because 225/50R17 and 235/45R18 are tied to specific wheel diameters and sub-model setups.
A modified TSX should be checked for actual wheel size, wheel width, and clearance at full steering lock before replacing tires. Looking at the current sidewall size alone is not always enough. It also helps to inspect for rubbing marks, uneven tread wear, or lowered ride height that could affect how a replacement tire behaves.
What should I inspect before driving a 2014 Acura TSX on new tires?
Before driving a 2014 Acura TSX on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model, and make sure inflation is set properly for the vehicle’s application. It is also worth checking alignment, brake condition, and suspension wear so the new tires are not exposed to problems that can shorten tread life or affect handling.
A short initial drive should include listening for rubbing, vibration, or pulling that could point to fitment or chassis issues. After that, recheck air pressure and look over the sidewalls and tread seating visually. Catching a clearance or alignment problem early is especially important when the car has replacement wheels or a history of suspension work.
How often should tires on a 2014 Acura TSX be inspected?
Tires on a 2014 Acura TSX should be inspected regularly, not just when tread appears worn. Monthly pressure checks are a good baseline, and visual inspections should look for uneven wear, sidewall cuts, bulges, punctures, or cracking. Because the TSX is often driven as a daily or occasional-use sport sedan, routine checks help catch issues before they affect ride quality or safety.
Inspection becomes even more important when the car sits for longer periods or is driven less often than it once was. Air loss can go unnoticed on an occasional-use vehicle, and suspension wear may show up first through unusual tread patterns. Checking the tires before longer drives is a simple way to avoid surprises on the road.
