The 2018 Lexus RC F pairs modern Lexus refinement with a naturally aspirated V8 coupe character that stands apart in an era increasingly defined by turbocharged performance cars. Its chassis and visual stance rely heavily on a staggered tire setup, with different sizes used at the front and rear to support the car’s balance and footprint. This RC F uses 255/35R19 front tires and 275/35R19 rear tires, both in radial construction on 19-inch wheels. Available choices focus on performance-oriented blackwall radials from BFGoodrich and Nitto across several series. The key decision is matching the correct front and rear sizes while confirming wheel specs and overall setup before replacement.
Which Tire Size Is Right for The 2018 Lexus RC F
The 2018 Lexus RC F uses two primary tire sizes, and the first step is recognizing that this is a staggered setup rather than a same-size arrangement at all four corners. Both sizes are radial tires for 19-inch wheels, with 255/35R19 used at the front and 275/35R19 at the rear. The real decision is selecting the right tire within each position, then confirming that the current wheels and vehicle setup still match those specifications.
275/35R19 is a modern metric radial size with a 275-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2018 Lexus RC F, this size is used at the rear as part of the car’s staggered fitment, so it should not be treated as interchangeable with the front size. Rear tire choices include BFGoodrich blackwall options in several g-Force series as well as the Nitto NT555 G2. This is the size to evaluate when replacing the rear pair and confirming that wheel width, tire profile, and rear clearance remain appropriate.
Sub-model fitment on the 2018 Lexus RC F is straightforward in one sense and specific in another: the covered configuration uses a dedicated front size and a dedicated rear size. Checking position matters because the car does not use the same tire size at both ends.

Tire Size & Fitment
What tire size fits a 2018 Lexus RC F?
The 2018 Lexus RC F uses a staggered radial tire setup with 255/35R19 at the front and 275/35R19 at the rear. Both sizes are designed for 19-inch wheels, so the car does not use one universal tire size at all four corners.
That matters when replacing tires because the front and rear positions should be matched to their correct sizes, not mixed casually. A quick check of the current wheel setup is smart, especially if the car has had aftermarket wheels or previous tire changes, since wheel width and clearance still need to suit each axle’s intended tire size.
What size rim does a 2018 Lexus RC F use?
The 2018 Lexus RC F uses 19-inch rims with both of its primary tire sizes. The front 255/35R19 and rear 275/35R19 both mount on 19-inch wheels, which keeps rim diameter consistent even though the tire widths differ between the two positions.
Rim diameter is only part of the fitment picture, though, because wheel width also affects whether a given tire is appropriate. Before choosing replacements, confirm that the wheels on the car are still the correct diameter and that their width matches the tire’s usable range, particularly on a performance coupe with staggered front and rear sizing.
Why does the 2018 Lexus RC F have more than one tire size?
The 2018 Lexus RC F has more than one tire size because it uses a staggered setup, with 255/35R19 on the front and 275/35R19 on the rear. That means the front and rear axles are assigned different tire widths rather than sharing one common size.
For the buyer, the practical takeaway is that tire selection starts with position on the car. Front replacements should stay with the front size, and rear replacements should stay with the rear size, unless the entire wheel and tire package has been changed intentionally and clearance, wheel specs, and overall compatibility have all been verified.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 and 275/35R19 tire set for a 2018 Lexus RC F?
Start with the correct staggered sizes: 255/35R19 for the front and 275/35R19 for the rear. From there, compare the available radial tire series, wheel-width specifications, load figures where stated, and how the tire will be used, whether that means routine street driving or a more performance-focused setup.
A good choice is not just about matching the size code on paper. It also means making sure the front and rear tires suit the wheels currently on the car and that the selected series aligns with the look and driving character you want, especially when comparing multiple performance-oriented options in the same fitment.
What brands offer tires for the 2018 Lexus RC F?
Tires for the 2018 Lexus RC F are available here from BFGoodrich and Nitto, depending on size and position. BFGoodrich appears in both the 255/35R19 front size and the 275/35R19 rear size, while Nitto is available in the 275/35R19 rear fitment.
Brand choice should be considered alongside tire series, wheel-width compatibility, and the exact axle position rather than as a stand-alone decision. Since the RC F uses different front and rear sizes, it is worth checking whether the brand and series you prefer are available for both ends of the car before committing to a full replacement plan.
What tire series are available for the 2018 Lexus RC F?
Available tire series for the 2018 Lexus RC F include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The front 255/35R19 fitment is offered in BFGoodrich g-Force series options, while the rear 275/35R19 fitment includes both BFGoodrich and Nitto choices.
Series names matter because they help distinguish the options within the correct size rather than forcing a buyer to compare by size alone. Once the proper front or rear fitment is confirmed, the next step is to compare each series by intended use, wheel-width suitability, and any stated load or weight details that may influence the final selection.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Lexus RC F?
A period-style approach on a 2018 Lexus RC F still starts with the correct modern staggered sizes: 255/35R19 front and 275/35R19 rear. Since this is a contemporary performance coupe rather than a vintage restoration case, the appearance decision is less about recreating an earlier sidewall treatment and more about keeping the correct low-profile, blackwall radial presentation.
Choosing within that look means comparing the available performance-oriented series while preserving the car’s intended front-to-rear sizing relationship. Owners who want the car to retain its original visual balance should avoid experimenting with mismatched profiles or alternate wheel diameters unless the entire package has been planned and checked carefully.
Does correct tire fitment matter for a 2018 Lexus RC F restoration or preservation project?
Correct tire fitment matters on a 2018 Lexus RC F because the car’s stance and proportions depend on its staggered 19-inch setup. Keeping the proper 255/35R19 front and 275/35R19 rear sizes helps preserve the appearance the car was designed around, even when the goal is clean preservation rather than a formal restoration.
Fitment also affects how convincingly the car presents as an unaltered example. A preservation-minded owner should pay attention to profile, wheel diameter, and tire position before focusing on brand or series details, since an incorrect front-to-rear arrangement is usually more noticeable than a change in the specific tire line chosen.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Lexus RC F?
Yes, modifications can affect tire fitment on a 2018 Lexus RC F even when the tire sizes remain 255/35R19 front and 275/35R19 rear. Changes such as aftermarket wheels, altered wheel widths, different offsets, suspension lowering, or body modifications can all influence clearance and how the tire sits within the wheel opening.
That means a size that suits a stock-style setup may need a closer look on a modified car. Any RC F with wheel or suspension changes should be checked for steering clearance, fender clearance, and overall wheel compatibility before replacement tires are chosen, especially because staggered setups leave less room for casual substitution.
What should I inspect before driving a 2018 Lexus RC F on new tires?
Before driving a 2018 Lexus RC F on new tires, inspect the wheel and tire positions to confirm that 255/35R19 is installed at the front and 275/35R19 at the rear. It is also wise to check inflation, verify that each tire is seated correctly on the wheel, and look over the wheels themselves for damage or irregular wear clues.
A short initial drive should be followed by another walk-around to make sure nothing is rubbing and pressures remain stable. On a performance coupe, it also helps to watch for any sign of alignment issues, vibration, or unusual tread behavior early, since those symptoms can point to wheel, suspension, or setup problems beyond the tires themselves.
How often should tires on a 2018 Lexus RC F be inspected?
Tires on a 2018 Lexus RC F should be inspected regularly, not just when replacement time arrives. A quick visual check for uneven wear, cuts, punctures, sidewall damage, and pressure loss is worthwhile before normal driving, and a more careful inspection makes sense anytime the car has been stored, driven hard, or fitted with new wheels.
Consistent inspection matters because low-profile performance tires can reveal setup issues quickly. Keeping an eye on tread condition, air retention, and any changes in ride feel helps catch problems before they become larger fitment or safety concerns, particularly on a staggered arrangement where front and rear tires are doing different jobs and cannot simply be rotated interchangeably.
