Ford F-350 SRW tire size
Original tire sizes for the Ford F-350 SRW, model years 2005 through 2024. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.
Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted, which can differ from what a previous owner put on. Our guide on reading a tire size shows exactly where to look.

Which brand should you pick?
Ford does not stamp its own approval code on tires the way Porsche or BMW do. Any tire in the right size that meets or exceeds the load index and speed rating on your door placard is a legitimate replacement, so pick on wet braking, tread life and price. Our picks for each size are on the size pages below.

The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
What those tires cost
About the Ford F-350 SRW
The F-350 SRW is the single-rear-wheel version of Ford's one-ton Super Duty pickup, sitting between the F-250 and the dual-rear-wheel F-350 DRW. It carries more payload than an F-250 on the same footprint and is bought by people who tow gooseneck and fifth-wheel trailers. Tire buyers land here because every fitment is a load-range-E light-truck tire and the difference between an E and a lesser rating is the difference between legal and overloaded.
Launched in 1998. Launched in 1998 for the 1999 model year, the Super Duty split Ford's heavy pickups onto their own platform with a separate cab, frame and front axle, ending the era when an F-350 was simply a heavier F-150.
How to tell the model years apart
Wheel and tire sizes follow the generation, not the badge, so identifying yours matters before you order.
1999-2004
First generation Super Duty
Tall, upright cab with a big rectangular grille and separate round headlights, and the 7.3-liter Power Stroke diesel for the first four years. Single-rear-wheel trucks ran narrow, tall 16-inch light-truck tires; the DRW versions used LT215/85R16 on six wheels.
Tire sizes: LT215/85R16
2005-2016
Second and third generation
A far bolder nose with a three-bar grille from 2008 and, from 2011, Ford's own 6.7-liter Power Stroke diesel replacing the Navistar engines. SRW trucks moved to 17- and 18-inch wheels, with LT245/75R17 on XL work trucks and LT275/65R18 on better-equipped models.
Tire sizes: LT245/75R17 and LT275/65R18
2017-2024
Fourth generation
Unveiled at the 2015 State Fair of Texas, this is the aluminum-bodied Super Duty with a fully boxed high-strength steel frame and a much squarer, taller grille. Tell it by the C-clamp headlight signature. SRW trucks run LT275/70R18 or, on 20-inch wheels, LT275/65R20.
Tire sizes: LT275/70R18 and LT275/65R20
What the press said
Super Duty reviews are dominated by capability numbers, and Ford has led the class on tow and payload ratings for most of the last decade. Reviewers praise the diesel's torque, the trailering camera systems and the cab's comfort on upper trims, and note that the aluminum body of the 2017-on trucks saved enough weight to raise payload. Criticism is consistent across generations: an unloaded ride that is harsh because the springs are sized for weight the truck is not carrying, a turning circle that is difficult in towns, and pricing on King Ranch and Platinum trims that reaches luxury-car territory.
Ford's mightiest pickup can be outfitted for any duty, no matter how super.
Car and Driver, 2026
Was it a success?
The Super Duty is one of the most profitable vehicle lines in the world and has led the US heavy-duty pickup market for decades. Resale on diesel four-wheel-drive crew cabs is exceptionally strong, to the point where used prices sometimes approach new. Reliability is good on the 6.7-liter Power Stroke from 2011 onward; the 6.0-liter diesel used from 2003 to 2007 is the generation to avoid, with head gasket and EGR failures well documented.
Did you know?
- The 2017 Super Duty's body is aluminum, which saved around 350 pounds and allowed Ford to add that weight back as payload.
- Ford does not publish separate Super Duty sales figures, so the truck's volume is hidden inside the F-Series total that has led the US market since 1977.
- The F-350 SRW and F-250 use identical tires and wheels in most configurations; the difference is in the springs, axle and the sticker on the door jamb.
Tire options on the Ford F-350 SRW
Every SRW fitment is a light-truck tire in load range E, rated around 3,750 pounds each: LT245/75R17 on older work trucks, LT275/65R18 and LT275/70R18 on 18-inch wheels, and LT275/65R20 on premium trims. Nothing is staggered and run-flats do not exist in these sizes. Load range is the single most important number on the sidewall here, since gross combined weight ratings run past 30,000 pounds with the diesel; fitting a load range C or D tire because it rides better will put you over the tire's rating when the trailer is hitched. Original equipment has been Michelin LTX A/T2, Goodyear Wrangler and General Grabber, with the AT-style tread standard on FX4 and Tremor packages. Owners who go off pavement move up to a 35-inch LT size, which usually needs a leveling kit on 18-inch wheels. In snow, a severe-service-rated all-terrain in the OE size is usually the practical choice, since dedicated winter tires in load range E are expensive and limited.
