ND MX-5 Tires — Street, Autocross, and Track
Tires are the single largest factor in the ND MX-5’s grip level. This page is the starting point: pick a tire by what you actually do with the car. Street-only, the occasional autocross, a full season of events, or regular track days all point to different tires — and the most common mistake is buying more tire than your driving needs.
If you’ve already committed to a discipline and want per-tire behavior in detail (how each warms up, when it fades, how many runs or sessions it lasts), jump to the deep dives:
- Autocross tires — single-run peak grip, warm-up, heat-cycle life, classing
- Track tires — sustained-lap behavior, fade, chunking/graining, durability across sessions
A note on the model picks here: tire lineups refresh every few years, but the reputation of a tire family (and the trade-offs between families) ages slowly. We name models and describe what owners report living with — not a “best tire of the year” ranking. Always check current reviews and availability in your exact size before buying.
Start here: what do you actually do?
Section titled “Start here: what do you actually do?”| You mostly… | Buy | Why |
|---|---|---|
| Daily drive, no events | UHP summer (PS4S / ExtremeContact Sport 02) | Best balance of dry/wet grip, tread life, quiet, all-weather competence |
| Daily + your first autocross or two | A great UHP/max-performance summer tire — not a 200-treadwear | You’ll learn faster on a forgiving tire, and 200TW is overkill that wears down on your commute. See the callout below. |
| Daily + a full autocross season | One streetable 200-treadwear set (Falken RT660) | Streetable enough to drive to events; competitive on course → autocross deep dive |
| Drive to track days / HPDE | A durable, heat-tolerant 200-treadwear (RT660) | Survives sustained laps without falling off → track deep dive |
| Dedicated competition (trailered/second set) | Discipline-specific — RE-71RS, A052, R888R, etc. | Peak grip per discipline; see the two deep dives |
| Winter / snow daily | Bridgestone Blizzak WS90 (195/50R16) | RWD + light rear needs real winter rubber, not all-seasons |
Doing your first autocross? You don’t need race tires.
Section titled “Doing your first autocross? You don’t need race tires.”This is the most common question from daily-driver owners, and the honest answer surprises people: for your first one or two events, run a good street tire. A set of 200-treadwear race tires won’t make you faster while you’re still learning car control — and they wear quickly on your daily commute, take heat to come in, and hydroplane in the rain. A quality ultra-high-performance summer tire (the same one that makes your commute fun) has plenty of grip to learn on. Buy the dedicated 200TW set once you’re hooked and chasing tenths — and at that point, the autocross tires page is for you.
Tire categories
Section titled “Tire categories”Ultra-high performance summer (UHP)
Section titled “Ultra-high performance summer (UHP)”- Use case: Street, occasional autocross, rare track day
- Characteristics: Good wet grip, reasonable tread life (25–40k miles), quiet, moderate dry grip
- Temperature range: Effective from cold; degrades above 200°F surface temp
- Examples of the category: Continental ExtremeContact Sport 02, Michelin Pilot Sport 4S, Bridgestone Potenza Sport
Max performance summer
Section titled “Max performance summer”- Use case: Aggressive street, regular autocross, light track
- Characteristics: High dry grip, reduced tread life (15–25k miles), louder, moderate wet grip
- Temperature range: Better heat tolerance than UHP; still has a tread life to manage
- Examples of the category: Michelin Pilot Sport Cup 2, BFGoodrich g-Force Rival S 1.5
Extreme performance / 200-treadwear
Section titled “Extreme performance / 200-treadwear”- Use case: Autocross competition, track days (driven to)
- Characteristics: Near-race-tire dry grip, short tread life (8–15k miles), poor wet grip, noisy
- Temperature range: Designed for sustained high temperatures
- Examples of the category: Bridgestone RE-71RS, Falken RT660, Yokohama A052, Toyo R888R, Nankang AR-1
DOT race tires
Section titled “DOT race tires”- Use case: Time attack, competition, track only
- Characteristics: Maximum dry grip, minimal tread life (one weekend to a few events), near-zero wet capability
- Temperature range: Requires warm-up; works best at elevated temperatures
- Not street-suitable: Extremely short life on street, dangerous in rain
All-season (not recommended for performance)
Section titled “All-season (not recommended for performance)”- Use case: Winter/wet commuting only
- Characteristics: Adequate in all conditions, excellent in none
- For the ND: Only relevant for year-round daily driving in mild climates; defeats the car’s purpose on track or twisty roads
Street tires: owner-favorite models
Section titled “Street tires: owner-favorite models”Price tiers are relative within the ND market: $ budget, $$ mainstream, $$$ premium.
| Model | Common ND sizes | Price | What owners report |
|---|---|---|---|
| Michelin Pilot Sport 4S | 205/45R17 | $$$ | The default “do-everything” street tire. Sharpest steering feel and top-tier dry and wet grip; the premium price is the main complaint. |
| Continental ExtremeContact Sport 02 | 205/45R17, 205/50R16 | $$ | Repeatedly rated a near-draw with the PS4S in independent road tests — about $200/set cheaper with better tread life. Owners describe a “race compound feel” on dry roads and strong wet confidence. |
| Bridgestone Potenza Sport / Goodyear Eagle F1 | 205/45R17 | $$ | Solid alternates if the two above aren’t available in your size. |
For a street ND that sees the occasional canyon run or autocross, the PS4S / ExtremeContact pair is where most owners land — the ExtremeContact wins on value, the Michelin on outright feel.
Winter tires
Section titled “Winter tires”| Model | Common ND sizes | Price | What owners report |
|---|---|---|---|
| Bridgestone Blizzak WS90 | 195/50R16 | $$ | ND owners running winter Blizzaks repeatedly say the car becomes “more fun in winter than summer” — quieter, more tossable, and confidence-inspiring even when provoked into a slide. |
Because the ND is rear-wheel drive with little weight over the driven wheels, owners in snow country are emphatic that real winter tires (not all-seasons) are what make cold-weather driving safe. A dedicated 195/50R16 winter set on a second pair of wheels is the common setup.
200-treadwear at a glance
Section titled “200-treadwear at a glance”This is the most-discussed category for ND owners, because the car is light enough that 200-treadwear tires transform it. The right one depends entirely on whether you autocross (rewards single-run peak grip) or run sustained track laps (rewards heat tolerance and consistency). The table below is the quick comparison; the autocross and track pages break down each tire’s behavior in detail.
| Tire | Best for | Peak grip | Holds up over a session? | Longevity | Price |
|---|---|---|---|---|---|
| Bridgestone RE-71RS | Autocross single runs | Highest, strong even cold | Falls off as it heats | ~100–150 autox runs | $$$ |
| Falken RT660 / RT660+ | Value all-rounder; autox + some track | High | Best lap 1–2, then ~0.5–1s off | Best of the group (~15–20 track sessions) | $$ |
| Yokohama A052 | Max grip in short, hard efforts | Very high | Fades in sustained heat | Short — wears fast | $$$ |
| Toyo Proxes R888R | Track heat-cycle workhorse | High | Holds heat well across laps | Long for track use | $$$ |
| Nankang AR-1 / NR-2S | Budget | Good | Decent | Decent | $ |
The short version owners repeat: RE-71RS for the fastest single autocross run, RT660 for the best value, durability, and consistency across a session, A052 when you want maximum grip for a short burst and don’t mind buying tires often, Nankang when budget decides it.
Fitment considerations
Section titled “Fitment considerations”See wheel and tire fitment for complete size compatibility. Key tire-specific notes:
Common sizes and what they mean
Section titled “Common sizes and what they mean”| Size | Width | Aspect | Use case |
|---|---|---|---|
| 195/50R16 | Narrow (stock Sport) | Good tire life | Street economy |
| 205/45R17 | Stock GT | Balanced | Daily+ |
| 205/50R16 | Slightly taller than stock | Common upgrade size | Street/autocross |
| 225/45R16 | Wider (requires 8” wheel) | More grip | Autocross/track |
| 245/40R17 | Wide (requires 8–9” wheel) | Maximum grip for size | Track, may need fender work |
Owners running 245/40R17 (typically on a 17x9) report it needs a fender roll front and rear, and that on a lowered car it can rub the plastic fender liner at full steering lock or over big bumps — exact behavior depends on ride height and alignment. A frequent reason owners choose 245/40R17 specifically is SCCA Solo classing: the ND in Street Touring (STR) runs up to a 245/40R17 on a 17x9 wheel (with a fender roll). If you compete, check your class limits before buying — they often dictate the size more than grip does.
Width vs. grip vs. hydroplaning
Section titled “Width vs. grip vs. hydroplaning”Wider tires provide more dry grip but reduce wet performance:
- Wider tires generally increase dry lateral grip, but the relationship is non-linear and depends on load, compound, and pressure
- Each 10mm of additional width reduces hydroplaning resistance
- The ND’s low weight means it benefits less from extreme widths than heavier cars
- Diminishing returns above ~225mm widely observed for a ~2,400 lb car
Tire pressure guidelines
Section titled “Tire pressure guidelines”| Use case | Front (cold) | Rear (cold) | Notes |
|---|---|---|---|
| Street | 29 psi | 29 psi | Per door placard; adjust for non-OEM sizes |
| Autocross | 32–36 psi | 30–34 psi | Adjust based on tire temp readings |
| Track | 30–35 psi | 28–33 psi | Target even tread temperature |
Hot pressures on track will be 4–8 psi above cold pressures. Set cold pressures so that hot pressures land in the tire manufacturer’s recommended range.
Reading tire temperatures
Section titled “Reading tire temperatures”For track and autocross, measure tread temperature at three points (inner, middle, outer) immediately after a session:
| Reading | Interpretation | Adjustment |
|---|---|---|
| Inner hotter than outer | Too much negative camber | Reduce camber or increase pressure |
| Outer hotter than inner | Not enough camber | Add camber or reduce pressure |
| Middle hotter than edges | Over-inflated | Reduce pressure |
| Edges hotter than middle | Under-inflated | Increase pressure |
| Even across the tread | Correct | Optimal setup |
Seasonal considerations
Section titled “Seasonal considerations”The ND MX-5 is rear-wheel drive with limited weight over the driven wheels. In cold or wet conditions:
- Summer performance tires lose significant grip below ~40–45°F / 5–7°C
- All-season tires provide adequate cold-weather grip but poor dry performance
- Winter tires in 195/50R16 are available and transform cold-weather confidence
- Many ND owners store the car in winter rather than drive on compromised tires
Tire life expectations (ND MX-5)
Section titled “Tire life expectations (ND MX-5)”| Category | Estimated life (miles) | Notes |
|---|---|---|
| UHP summer | 25,000–40,000 | Depends on alignment and driving style |
| Max performance | 15,000–25,000 | More aggressive compound wears faster |
| 200-treadwear | 8,000–15,000 | Track events consume life rapidly |
| DOT race | 1,000–5,000 | Designed for competition, not commuting |
These are street-driving estimates. Track use accelerates wear dramatically — a 200-treadwear tire may last 5+ track days or as few as 2 depending on conditions and driving intensity.
