FL5 Factory Tire Specifications

All FL5 Civic Type R models came with identical factory tire specifications across all markets:

The factory Michelin Pilot Sport 4S tire carries a 93Y XL (Extra Load) rating, indicating a reinforced internal structure capable of carrying heavier loads at higher inflation pressures compared to Standard Load tires. This load rating is critical for the FL5’s front-heavy weight distribution (62% front / 38% rear) and high cornering loads generated during spirited driving. When shopping for tires, ensure the load index meets or exceeds 93 and always select XL (Extra Load) rated tires rather than SL (Standard Load) variants.

When using a tire size different from the OEM specification, the rule of thumb is to maintain a ±3% variance in overall tire diameter. This ensures:

• Speedometer and odometer accuracy remains acceptable
• ABS, traction control, and VSA systems function properly
• Vehicle dynamics such as braking and handling are not adversely affected
• Sufficient tire clearance is maintained within the wheel wells
• Indirect TPMS system can properly calibrate

The following sections list all compatible tire sizes within 3% of the factory diameter. Please note that these are theoretical tire size fitments based on diameter calculations. Having a size listed here does not mean a tire is manufactured in that size, nor that your desired tire model will be available in that size. Consult the Tire Recommendations by Category section to verify actual tire availability.

18” Tire Sizes for the FL5 Civic Type R

The 18” wheel diameter is the most popular choice for FL5 owners seeking improved durability, reduced unsprung weight, and access to superior tire compounds. The factory 265/30R19 has an overall diameter of 25.3 inches (64.3 cm). The 18-inch sizes below maintain this diameter within the 3% tolerance.

The 18” diameter offers the widest variety of tire options across all performance categories, from extreme performance summer tires to all-season and winter compounds. The 265/35R18 size paired with 18x9.5” +45 wheels represents the most common downsizing setup for the FL5, providing near-perfect diameter match to OEM (-0.2% variance) while dramatically improving ride quality and pothole resistance.

19” Tire Sizes for the FL5 Civic Type R (OEM)

The 19-inch wheel diameter is the factory specification for the FL5. While these sizes deliver sharp steering response and minimal sidewall flex, they sacrifice ride quality and are highly susceptible to wheel damage from road irregularities.

Tire Recommendations by Category

The FL5’s front-wheel-drive layout, 315 hp of turbocharged power, and high cornering capabilities make tire selection critical for performance and safety. The 18” diameter offers the widest variety of options across all categories.

Extreme Performance Summer Tires

For track days, autocross, and maximum dry grip, extreme performance summer tires deliver the ultimate in cornering capability. These tires typically feature 200-treadwear ratings or lower, aggressive tread compounds, and stiff sidewalls that provide exceptional steering response and lateral grip. The trade-off is cost, reduced treadlife, and unsuitable performance in temperatures below 40°F (4°C).

Popular choices in this category include the Yokohama ADVAN A052, Bridgestone Potenza RE-71RS, Falken Azenis RT660+, Nankang Sportnex CR-S. These tires are purpose-built for competitive driving where ultimate grip outweighs daily usability.

Max Performance Summer Tires

The sweet spot for enthusiastic street driving and occasional track use, max performance summer tires deliver exceptional dry and wet performance while maintaining the road manners expected of high-end vehicle fitments. These tires typically feature 300-treadwear ratings, refined ride quality, and predictable behavior that can handle spirited driving and daily commutes with equal capability. The trade-off is reduced ultimate grip compared to extreme performance tires, though they compensate with superior wet traction, longer tread life, and better everyday usability.

Popular choices in this category include the OE-speced Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, and Bridgestone Potenza Sport. These tires are engineered for drivers seeking performance that can transition from canyon runs to daily commutes without compromise.

Ultra High Performance All-Season Tires

For drivers seeking year-round capability without sacrificing performance, ultra high performance all-season tires balance dry and wet grip while remaining usable in light winter conditions. These tires typically feature 500+ treadwear ratings, refined ride quality, and the quiet comfort expected of premium vehicle fitments. The trade-off is reduced ultimate dry grip compared to summer tires, though they compensate with genuine winter capability that summer tires cannot provide.

Popular choices in this category include the Michelin Pilot Sport All Season 4, Continental ExtremeContact DWS06 Plus, and Bridgestone Potenza RE980AS+. These tires are engineered for drivers in moderate climates who want one set of tires capable of handling everything from spirited driving to snow-dusted morning commutes.

Winter / Snow Wheels and Tires

For true winter conditions, dedicated winter tires are essential. The FL5’s front-wheel-drive layout and high power output demand proper winter tires for safe operation in snow and ice. A popular winter setup is downsizing to 18x8.5” or 18x9” wheels with approximately +45 offset paired with 245/40R18 or 255/40R18 winter tires. The narrower footprint and taller sidewall maximize contact pressure to cut through snow and slush while providing additional sidewall protection against winter potholes.

Performance Winter and Snow

Performance winter tires balance winter grip with year-round usability. These tires feature aggressive tread patterns with sipes (small slits) to enhance snow and ice traction, while maintaining reasonable handling on dry roads. These tires are engineered for drivers in moderate winter climates who need reliable cold-weather performance without sacrificing too much summer handling.

Studless Ice and Snow

Studless ice and snow tires deliver maximum winter performance without metal studs, using advanced siping and tread rubber compounds that remain pliable in extreme cold. These tires excel in severe winter conditions including ice, packed snow, and slush, but trade away some dry-road handling and tread life. These tires are best suited for regions with long, harsh winters where maximum winter grip outweighs summer usability concerns.

Tire Pressure and TPMS Calibration

The FL5 employs an indirect TPMS system that infers pressure loss by comparing relative wheel speeds, rather than using physical sensors mounted in each wheel. This means you do not need to transfer sensors or purchase additional TPMS units when installing aftermarket wheels.

Calibration Protocol

Whenever wheel size or tire pressure is adjusted, the TPMS system must be recalibrated:

1. In your infotainment system navigate to: Settings > Vehicle > TPMS Calibration
2. Ensure all tires are set to desired cold pressure
3. Initiate calibration - the system will learn the new rolling radius
4. Drive for 10-20 minutes to complete the learning cycle

Important Fitment Notes

While all sizes listed are within 3% diameter tolerance, tire size alone does not determine fitment. You must also consider:

Wheel Width: Tire manufacturers publish recommended wheel width ranges for each tire size. A 265/30R19 tire on an 19x8.5” wheel will have different fitment characteristics than the same tire on an 19x9.5” wheel. See our FL5 CTR Wheel and Tire Combo Cheatsheet for validated combinations.

Wheel Offset: Lower offsets push the tire outward toward the fender, increasing the likelihood of rubbing. See the FL5 Wheel Fitment Guide for offset recommendations.

Suspension Height: Lowered cars have reduced fender-to-tire clearance. What fits on stock suspension may rub when lowered.

Tire Shoulder Profile: Some high-performance tires, particularly 200TW “competition” tires, feature “square” shoulders that measure wider than their stated section width. For instance, a 265/35R18 Federal 595RS-RR may measure closer to 275mm in actual width. This can affect fender clearance on aggressive fitments.

Load Rating Requirements: Always select XL (Extra Load) rated tires for the FL5 CTR. The OEM uses 93Y XL. Never downgrade to SL (Standard Load) tires, as they cannot safely support the vehicle’s weight and dynamic loads during cornering and braking.

Where to Buy Tires

For purchasing tires, we highly recommend Tire Rack. Their prices are highly competitive, and their comprehensive network of recommended installers ensures you have a nearby expert for mounting and balancing. You can also ship directly to your installer for ultimate convenience.
