About the Mickey Thompson Street Comp

Race-Bred Grip Built for the Street

Best forMuscle cars, classic performance builds, and Pro Touring vehicles driven on public roads in warm-weather conditions.

The Mickey Thompson Street Comp is an ultra-high-performance summer tire built for muscle cars, classic builds, and Pro Touring applications. It delivers strong dry and wet grip, responsive steering, and confident high-speed cornering during warmer driving conditions. Drivers who demand both aggressive looks and real-world street performance will find this tire a capable, purpose-built choice.

The Street Comp uses a symmetrical tread pattern paired with a performance-tuned rubber compound engineered for enhanced grip, traction, and steering response on both dry and wet pavement. Reinforced shoulders and dual center ribs maintain stability and control at elevated speeds, while lightweight construction helps resist uneven wear and supports long-term durability. Note: this tire is not suited for use when temperatures consistently fall below 45°F.

Questions about this tire

What does 245/40R18 97Y mean?

245 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 97 is the load index (1,609 lbs per tire), and Y is the speed rating (up to 186 mph).

Can I use the Street Comp year-round?

The Street Comp is a dedicated summer tire, meaning its compound is optimized for warm-weather performance. Once temperatures consistently drop below 45°F, grip and pliability decrease significantly, making this tire unsuitable for cold, winter, or snowy conditions. Drivers in climates with real winters should plan to swap to an all-season or winter tire during colder months.

Is the Street Comp a good fit for late-model American muscle cars?

Yes — the Street Comp is specifically designed with muscle car and Pro Touring applications in mind. Its tread compound, shoulder design, and dual center ribs are engineered to handle the high torque and speed demands common to these vehicles while maintaining predictable handling on public roads.

How does the Street Comp perform in wet conditions?

The Street Comp's compound and tread design are tuned to provide traction and grip on wet pavement, not just dry. That said, as a summer UHP tire, it performs best in warmer temperatures; cold or near-freezing wet roads will reduce its effectiveness compared to an all-season alternative.

What rim sizes does the Street Comp come in?

TFS Wheels stocks the Street Comp in 15 sizes spanning 17-inch through 20-inch rim diameters. Use the size selector on this page to confirm fitment for your specific vehicle.

Does the Street Comp carry a mileage warranty?

Warranty coverage is provided per the manufacturer's terms. We recommend contacting us or reviewing Mickey Thompson's current warranty documentation for the specific details applicable to your size and purchase.

Buying from TFS Wheels

Shipping, returns & guarantees

Authorized Dealer — 100% Brand New Wheels & Tires

TFS Wheels is an authorized dealer for every brand we carry. Every wheel and tire we ship is brand new, unused, and packaged in its original manufacturer's box. We never sell refurbished, demo, or return-stock product. All manufacturer warranties apply and our warehouse is staffed by people who only handle wheels and tires — no in-transit damage, no test-fits, no surprises.

Free Shipping (Lower 48)

Free shipping on every order — wheels, tires, and accessories — to the contiguous United States. No minimum order, no hidden fees.

Standard delivery is 4–7 business days; expedited is 1–4 business days. Orders placed before 1:00 PM ET typically ship the same day. We do not ship internationally or to PO boxes.

Fitment Guarantee

If a wheel or tire marked "Direct Fit" or "Aftermarket Fit" for your vehicle arrives and does not fit as expected, we cover both the restocking fee and return shipping. The same applies if the bolt pattern does not match — provided your vehicle information was submitted at checkout.

To qualify for the guarantee, enter your year, make, model, and submodel before placing the order.

Manufacturer's Warranty

Every wheel and tire is covered by the full manufacturer's warranty against defects in materials and workmanship. Coverage terms vary by brand — most cover structural integrity for the life of the wheel and finish for 1 to 2 years from purchase. If you ever have a warranty question, contact us first; we work directly with the manufacturer on your behalf so you don't have to.

Accessories Included with Your Order

When you submit your vehicle information at checkout, the right lug nuts and (if needed) hub-centric rings are automatically added to your cart in the correct sizes — no guessing, no separate ordering.

TPMS sensors are also available in the cart. We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed. This typically saves customers the dealer or installer's programming fees, which often run several dozen dollars per wheel.

Returns

Returns are accepted within 30 days of purchase on items in new, unused condition. A 25% restocking fee applies to general (change-of-mind) returns, and the buyer covers return shipping.

The restocking fee and return shipping are waived for incorrect items, transit damage, or fitment issues when vehicle information was provided at checkout. Single wheels, single tires, mounted items, special orders, and accessories (lug nuts, locks, hub-centric rings, TPMS sensors, installation kits) are final sale.
