For 35×12.50R18 tires, start with the General Grabber A/TX for all-terrain use, the Nitto Ridge Grappler for a hybrid-terrain design, or the Toyo Open Country M/T for a mud-terrain-focused build. The right choice depends on how you drive and whether the exact tire specification is approved for your vehicle and wheels.
The size alone is not a fitment guarantee. These three listings differ in load range and service description, and even two tires marked 35×12.50R18 can have different measured widths and diameters. Have the complete combination checked before ordering a set.
35×12.50R18 tire shortlist
| Tire and verified listing | Exact size and rating | Best reason to compare it |
|---|---|---|
| General Grabber A/TX, 04508240000 | 35×12.50R18LT, 123R, load range E | All-terrain design with the three-peak mountain snowflake marking |
| Nitto Ridge Grappler, 217130 | 35×12.50R18LT, 128Q, load range F | Hybrid-terrain pattern for mixed pavement and off-road use |
| Toyo Open Country M/T, 360090 | 35×12.50R18LT, 123Q, load range E | Open-shoulder mud-terrain tread for an off-road-focused vehicle |
These are specific tire variants, not interchangeable approvals for every truck running 18-inch wheels. The linked retail products are individual tires; confirm quantity, mounting charges and any additional services before comparing the total cost.
General Grabber A/TX: the all-terrain starting point
The Grabber A/TX is General’s all-terrain option intended to balance pavement use with off-road capability. The manufacturer describes a durable tread construction, the three-peak mountain snowflake symbol and provision for winter studs. For a truck that spends much of its time on roads but also sees unpaved routes, this is the first category to investigate.
The verified Amazon listing identifies part 4508240000, equivalent to the leading-zero manufacturer number 04508240000. General’s manufacturer product flyer confirms that exact article number as a 35×12.50R18LT 123R, load-range-E, raised-white-letter tire with an approved rim-width range of 8.5–11 inches.
Check the supplied part number: General’s current online specification data uses 04505650000 for this size, while the verified retail listing retains 04508240000. Ask the seller to confirm which article number and production specification will arrive. Do not silently treat the two records as the same revision, especially when matching existing tires.

Nitto Ridge Grappler: a hybrid-terrain option
Nitto identifies the Ridge Grappler as a hybrid-terrain tire. Its tread includes staggered shoulder lugs, stone ejectors and supported tread blocks. This makes it worth comparing when you want a design positioned between a conventional all-terrain and an aggressive mud-terrain.
The exact 217130 variant is 35×12.50R18LT F 128Q. Nitto lists an inflated diameter of 34.76 inches, width of 12.52 inches, and an approved rim-width range of 8.5–11 inches, measured on a 10-inch wheel. Those published dimensions are more useful for clearance planning than assuming every “35” is exactly 35 inches tall.
Its load-range-F specification differs from the load-range-E options here. Do not select it solely because F sounds stronger, or assume a higher load range improves comfort. Confirm the required load capacity at the correct inflation pressure and the wheel’s rating with your installer. This guide does not claim it is quieter or better braking than the other tires; those would require comparable testing.
Toyo Open Country M/T: the mud-terrain choice
The Open Country M/T uses hook-shaped tread blocks, open shoulders and tread extending over the shoulder. Toyo positions those features for off-road traction and clearing mud and debris. It is a sensible candidate when difficult off-road surfaces are a central part of the vehicle’s job.
The verified listing is 360090, 35×12.50R18LT 123Q E. Toyo’s current size table distinguishes it from the 360820 variant in the same nominal size, which is rated 128Q. For 360090, the table gives a 35-inch diameter, 13.2-inch width and an approved 8.5–11-inch rim range.
That measured width is an important difference from the Nitto above. More aggressive shoulders and a larger actual section width can change available clearance. Choose the mud-terrain category for a real terrain requirement, and consider the pavement, noise and winter-driving trade-offs with your tire professional rather than buying on appearance alone.
What the size means, and what it leaves out
In 35×12.50R18, the first number is nominal overall diameter in inches, 12.50 is nominal width, R identifies radial construction, and 18 is the wheel’s bead-seat diameter. The tire therefore requires the correct 18-inch wheel. A 35×12.50R17 or 35×12.50R20 listing is not a substitute.
A nearby metric size is not automatically equivalent either. Actual diameter, width, load capability, rim-width approval and clearances all need checking. Product selectors sometimes group many sizes and ratings on one page, so review the selected variation, full service description and manufacturer part number at checkout.
Fitment checks before buying 35-inch tires
- Vehicle approval: verify the year, model, trim, axle loads and original tire requirements.
- Wheel compatibility: check diameter, approved width, load and pressure ratings, offset and backspacing.
- Clearance through movement: inspect at steering lock and suspension travel, not only with the vehicle parked straight.
- Vehicle systems: ask whether the size change affects speedometer calibration, braking, stability systems or drivetrain operation.
- Spare and matching: confirm the spare strategy and any manufacturer limits on circumference differences, especially on four-wheel-drive vehicles.
A lift or leveling kit does not by itself establish safe fitment. Toyo’s safety guidance warns that larger tires and suspension changes can alter handling and rollover characteristics. A professional should evaluate the whole vehicle rather than approving a purchase from a generic “fits trucks and SUVs” retail field.
Load, speed and pressure are separate checks
The 123 or 128 number is the load index; Q or R is the speed symbol. Load range E or F is another construction/load designation. Select a replacement that meets the vehicle’s required capacity and service specification. Increasing tire capacity does not increase the vehicle’s rated payload or towing capacity.
Use the vehicle manufacturer’s cold-pressure specification for an approved original-size setup. When changing size or tire type, obtain the appropriate recommendation from the tire manufacturer or qualified dealer using load-and-inflation information. The tire’s maximum sidewall pressure is not an automatic everyday target.
NHTSA recommends monthly pressure checks with cold tires and an accurate gauge. Also inspect the tires and include the spare. Mounting, balancing and inspection belong with a tire professional; a tire that has been driven flat may be damaged even after it holds air.
Do you need winter capability?
General documents the three-peak mountain snowflake marking on the A/TX. Do not assume the other tires provide equivalent winter capability because a seller uses “all-season” or the tread looks aggressive. Check the actual sidewall and manufacturer specification.
For frequent snow and ice, compare dedicated winter tires as well. Toyo’s winter-tire guidance explains why winter compounds and tread designs can improve cold-weather performance. No tire removes the need to slow down and leave extra stopping distance.
Bottom line: begin with the Grabber A/TX for an all-terrain brief, compare the Ridge Grappler for hybrid use, and choose the Open Country M/T when mud-terrain capability is the priority. Buy only after the exact part, load rating, wheels and vehicle clearances have been confirmed.
