About the Arroyo Tamarock R/T

Rugged grip built for trucks that work hard.

Best forLight truck owners who regularly tackle off-road trails, gravel, or mixed terrain while still driving on public roads.

The Arroyo Tamarock R/T is a rugged/terrain hybrid tire built for light trucks that split time between paved roads and demanding off-road conditions. It delivers reliable traction across dirt, gravel, mud, and wet pavement, making it a strong choice for truck owners who need more bite than a standard all-terrain but still want composed on-road behavior.

The symmetrical tread features a wide, flat contact patch and a stable block layout that keeps consistent ground contact for predictable handling. Laterally oriented blocks with stepped edges and aggressive sidewall biting edges dig into loose or uneven terrain for added grip. Lateral and zigzag grooves work together to evacuate water from the footprint, improving wet-surface traction and resisting hydroplaning.

Questions about this tire

What does 265/70R18 116T mean?

265 is the tread width in millimeters, 70 means the sidewall is 70% of that width, and R18 is the 18-inch rim it mounts on. 116 is the load index (2,756 lbs per tire), and T is the speed rating (up to 118 mph).

Is the Tamarock R/T better suited for on-road or off-road use?

The Tamarock R/T is designed as a hybrid that handles both, but it leans toward drivers who spend meaningful time off-road. Its tread pattern and sidewall design prioritize grip on dirt, gravel, and uneven terrain. On pavement it remains functional and composed, though dedicated highway tires will offer a quieter, smoother ride for purely on-road driving.

Can this tire handle mud and rocky trails?

Yes. The stepped lateral blocks and aggressive sidewall biting edges are specifically engineered to grip on loose, muddy, and rocky surfaces. That said, for extreme mud conditions requiring maximum self-cleaning, a dedicated mud-terrain tire may provide an edge over this R/T hybrid.

Is the Tamarock R/T rated for severe snow or winter driving?

No. The Tamarock R/T does not carry the Three-Peak Mountain Snowflake certification, so it is not rated for severe snow service. Drivers in regions with heavy winter weather should consider a dedicated winter or 3PMSF-certified tire for those months.

What is the mileage warranty on the Tamarock R/T?

The Tamarock R/T is covered under Arroyo's manufacturer warranty rather than a specific mileage treadwear guarantee. Contact Arroyo or your dealer directly for full warranty terms and conditions.

What vehicles is the Tamarock R/T designed for?

This tire is built for light trucks and is available in 42 sizes spanning 16-inch through 24-inch rim diameters, covering a wide range of pickup trucks and truck-based SUVs.

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.
