About the Gladiator X Comp HP

Track-Inspired Grip for the Street

Best forDrivers of sports cars, performance coupes, and spirited sedans seeking sharp handling and strong grip in warm-weather conditions.

The Gladiator X Comp HP is a high-performance summer tire built for sports cars, performance coupes, and spirited sedans. Its asymmetrical tread pattern and motorsport-inspired compound deliver confident grip, precise cornering, and responsive steering in warm, dry, and wet conditions. Drivers who push their vehicles hard will find the X Comp HP rises to the occasion as temperatures climb.

The X Comp HP uses a motorsport-grade rubber compound that builds grip as operating temperature increases, rewarding aggressive driving with more traction, not less. An expanded contact patch keeps more rubber planted during hard acceleration and cornering, while cross-patch siping and twin inner grooves channel water away from the tread face for improved wet-road confidence. A dual-layer polyester carcass with steel-belted radial construction sharpens steering response and maintains stability at elevated speeds.

Questions about this tire

What does 315/30ZR19 100Y mean?

315 is the tread width in millimeters, 30 means the sidewall is 30% of that width, and R19 is the 19-inch rim it mounts on. 100 is the load index (1,764 lbs per tire), and Y is the speed rating (up to 186 mph).

Is the Gladiator X Comp HP a summer-only tire, or can I use it year-round?

It is a warm-weather performance tire, not an all-season product. The soft, grippy compound that makes it effective in warm conditions stiffens noticeably when temperatures drop below roughly 40–45 °F, reducing traction and increasing the risk of poor handling. If you live in a region with cold winters, a dedicated winter or all-season tire is a safer choice for those months.

How does the X Comp HP perform in the rain?

The tire's asymmetrical tread incorporates cross-patch siping and two interior grooves designed to push water out from under the contact patch, helping to maintain grip on wet pavement. While it handles typical rain conditions well, it is not intended for standing water at high speed, so appropriate speed and following distances remain important in heavy rain.

What kind of vehicles is this tire designed for?

The X Comp HP targets passenger vehicles with a performance focus — sports cars, coupes, and performance-oriented sedans or crossovers. Its construction and compound are tuned for drivers who want responsive steering and confident cornering rather than maximum ride comfort or fuel economy.

Is the X Comp HP a radial tire, and how is it constructed?

Yes, it uses steel-belted radial construction paired with a two-ply polyester carcass. This combination provides the structural integrity needed for high-speed stability while keeping the sidewall responsive enough for quick directional changes.

What mileage warranty does the Gladiator X Comp HP carry?

The X Comp HP is covered under the manufacturer's standard warranty rather than a separate mileage guarantee. For full warranty terms and conditions, contact us directly or refer to Gladiator's official warranty documentation.

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.
