About the Continental ProContact GX

Precision Engineering for Every Mile Ahead

Best forAn ideal everyday tire for drivers of performance coupes, sedans, and CUVs seeking confident handling, all-season capability, and a comfortable ride.

The Continental ProContact GX is an all-season touring tire built for drivers of performance coupes, sedans, and CUVs who expect confident handling alongside everyday comfort. Selected as original equipment on a range of performance vehicles, it delivers responsive steering, reliable year-round grip, and a smooth, composed ride — making it a capable choice for drivers who don't want to compromise between performance and refinement.

The ProContact GX uses a symmetrical, multidirectional tread design engineered to maintain grip across a variety of road conditions. Four circumferential grooves channel water away from the contact patch to resist hydroplaning, while dense siping supports traction in light snow and cold weather. Select sizes are available with SSR run-flat construction, Conti-Silent noise-dampening technology, and ContiSeal self-sealing capability. The tire carries a 45,000-mile tread life warranty and is backed by Continental's Total Confidence Plan.

Questions about this tire

What does 235/55R18XL 104H mean?

235 is the tread width in millimeters, 55 means the sidewall is 55% of that width, and R18 is the 18-inch rim it mounts on. 104 is the load index (1,984 lbs per tire), and H is the speed rating (up to 130 mph).

Are any ProContact GX sizes available as run-flat tires?

Yes, select sizes of the ProContact GX are built with Continental's Self-Supporting Runflat (SSR) technology. If a puncture or sudden pressure loss occurs, SSR-equipped tires allow you to continue driving up to 50 miles at speeds under 50 mph, giving you time to reach a service location safely. Not every size in the lineup includes this feature, so confirm at the time of purchase if run-flat capability is a requirement.

How does the ProContact GX handle wet roads?

The ProContact GX is designed with four circumferential grooves that actively channel rainwater out from under the tire, reducing the risk of hydroplaning on wet pavement. The tread pattern and siping work together to help maintain contact and grip when roads are damp or slick. Drivers generally report solid wet-weather confidence for everyday commuting and highway use.

Can I use the ProContact GX through winter weather?

The ProContact GX handles light winter conditions reasonably well — its all-season compound, wide grooves, and siping provide adequate traction in light snow and cold temperatures. However, it is not Three-Peak Mountain Snowflake certified, which means it has not met the threshold for severe-snow service. If you regularly face heavy snowfall, packed snow, or significant ice, a dedicated winter tire will outperform it in those conditions.

Is the ProContact GX a quiet, comfortable tire?

Continental computer-tunes the tread pattern to minimize road noise, and most drivers find the ProContact GX notably quiet and smooth for a performance-oriented all-season tire. That said, some owners of run-flat-equipped sizes report slightly more road noise and a firmer ride compared to standard construction tires — a common trade-off with run-flat technology. Select sizes with Conti-Silent technology can help reduce interior cabin noise further.

What warranty coverage comes with the ProContact GX?

The ProContact GX includes a 45,000-mile tread life warranty. It is also covered under Continental's Total Confidence Plan, which bundles road hazard protection, a customer satisfaction trial period, flat tire roadside assistance, and a limited manufacturer warranty. Restrictions and limitations apply, so review Continental's current warranty terms for full details.

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.
