OEM wheel and tire fitment specs for the 2006 Ford F-350, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2006 Ford F-350 Fitment Specs
Baseline mounting dimensions used for interchange decisions.
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.

Important notes. The 2006 F-350 was offered in single rear wheel and dual rear wheel versions. Wheel sizes, offsets, and tire sizes can differ significantly between SRW and DRW as well as trim packages and GVWR. If a value is unknown above, confirm it on your specific truck using the door-jamb tire and loading sticker, the owner’s manual, or an OEM parts lookup by VIN. You can also measure your current wheels and use the on-page calculator to back into offset and backspacing.
How To Use The Wheel Interchange Calculator
Pick Wheels from (donor vehicle). Choose the vehicle or manually enter a wheel and tire size you want to try.
Pick Installed on (your vehicle). Select 2006 Ford F-350 or enter your current wheel and tire size.
Set Custom wheel size. Adjust rim diameter, width, and offset to match what you plan to install. The tool will show how far the wheel moves inboard and outboard compared to your current setup.
Set Custom tire size. Adjust section width and aspect ratio. When you change rim diameter, the tire comparison updates overall tire diameter so you can keep speedometer error in check.
Review clearances. Check inner clearance to suspension and brakes, outer poke relative to fenders, and overall tire diameter change. Aim to keep overall tire diameter within about plus or minus 3 percent unless you have confirmed gearing and clearance are acceptable.
Save your numbers. Record the offset and backspacing that provide safe inner and outer clearances before purchasing.
Fitment Checklist Before You Buy
Bolt pattern. Must be 8x170 to fit the studs without adapters.
Center bore. Wheel center bore must be at least 124.9 mm. Exact 124.9 mm typically centers on the hub. If larger, the wheel will center on the lugs. If you choose to run hub-centric rings to reduce a larger bore, use quality metal rings with adequate temperature and load capability for a heavy truck.
Thread size and lug seats. The studs are M14 x 2.00. Match lug nut seat type to the wheel seat design. Do not mix conical, mag, or spherical seats. Verify hex size clearance in wheel holes.
Load rating. Each wheel and tire must be rated at or above the axle’s GAWR. Example method. If your rear GAWR is 7,000 lb on SRW, each rear wheel and tire should be rated at or above 3,500 lb. For DRW, divide by four. Check your door sticker for GAWR values.
Offset and backspacing. Incorrect offset can cause rubbing on suspension or fenders and alters scrub radius. Use the calculator to visualize inner clearance to control arms, leafs, and brake calipers and outer poke relative to fenders and mudflaps.
Brakes and calipers. Verify spoke and barrel clearance over front calipers and rear drums or discs. Test fit before mounting tires.
SRW vs DRW. Dual rear wheel setups use different offsets and wheel constructions. Do not mix SRW and DRW wheels without confirming spacing, offset, and load ratings.
Stud engagement. A common safety target is full thread engagement at least equal to the stud diameter. If wheels are thicker or you add spacers, verify you still achieve proper engagement.
Spacers or adapters. If used, they must match 8x170, be hub-centric where possible, use high-grade studs, and meet or exceed axle load. Re-torque after 50 to 100 miles.
Tire clearance at full articulation. Check at full steering lock and with the suspension compressed. Inspect cab steps, inner fender liners, sway bar links, and brake hoses.
TPMS and valve stems. If your truck is equipped, ensure compatible sensors and correct clamp-in or snap-in high-pressure stems for your load range.
Plus Sizing And Common Upgrades
Keep overall diameter close. Staying within about plus or minus 3 percent of stock overall diameter limits speedometer and ABS impact. Use the calculator to dial in section width and aspect ratio when changing rim diameter.
Mind width and offset. Wider wheels often require reduced positive offset to clear inner suspension, which can increase outer poke and fender contact. Validate with the calculator and a physical test fit.
Tire load range. Choose a tire load index and load range that meet or exceed your GAWR and towing needs. Many heavy-duty truck tires are Load Range E or higher. Verify on the sidewall and door sticker.
Unsprung mass. Larger diameter wheels and heavy tires can reduce braking and acceleration and increase wear on hubs and steering. Consider lighter yet properly rated wheels where possible.
Backspacing and offset relationship. Backspacing in inches equals half the measured wheel width plus the 0.5 inch flange allowance, plus offset converted to inches. backspacing = (wheel width + 1) ÷ 2 + offset(mm) ÷ 25.4.
Installation Tips
Test fit each axle without tires first. Spin the wheel by hand and check caliper and suspension clearance.
Clean mating surfaces. Remove rust and debris from the hub face and the wheel mounting pad so the wheel sits flush.
Hand start all lug nuts. Use a star pattern. Seat the wheel fully before applying final torque.
Torque to the Ford service manual specification. Apply torque in stages. Do not lubricate studs or lug seats unless the manual explicitly instructs.
Re-torque after 50 to 100 miles. Re-check again after towing or off-road use.
Verify clearance under load. After installation, drive slowly in a tight circle both directions and over a bump to confirm no rubbing.
DRW specifics. Ensure correct inner and outer wheel orientation, clean mating surfaces between duals, and adequate dual spacing to prevent heat buildup.
Which other vehicles share wheels with a 2006 F-350
Do not assume interchange by model name alone. Use the calculator to compare a donor vehicle’s wheel specs against your 2006 F-350 and verify three things. Bolt pattern 8x170. Center bore at least 124.9 mm. Offset and width that preserve inner and outer clearance. Always confirm load rating and test fit.
What is the stock wheel offset for a 2006 F-350
It varies by SRW vs DRW and trim. Check the back of your OE wheel for an ET stamp, the owner’s manual, or ask a Ford parts department with your VIN. You can also measure backspacing and compute offset using the calculator.
What tire size came from the factory
It varies by configuration. Read the tire and loading sticker on the driver door jamb or the owner’s manual. Enter that size in the calculator as your baseline before testing alternatives.
Can I use 8x6.5 wheels on my truck
Not directly. 8x6.5 is a different bolt circle. Adapters exist but add thickness, change effective offset, and must meet or exceed axle load. If you choose adapters, buy high-quality, hub-centric parts, verify stud engagement, and re-torque after 50 to 100 miles. Many owners avoid adapters on heavy towing setups.
Do I need hub-centric rings
If your aftermarket wheel has a larger bore than 124.9 mm, the wheel will center on the lugs. Many trucks run safely lug-centric with correct conical-seat nuts and proper torque. If you want rings, choose metal rings with adequate heat and load capacity. Best practice is to use a wheel with the correct bore.
What lug nut torque should I use
Refer to the Ford service manual or the tire and loading sticker for your exact spec. Torque values can vary by wheel type and finish. Do not lubricate studs or seats unless the manual specifies. Torque in stages and re-torque after the first 50 to 100 miles.
Can I swap DRW and SRW wheels
Usually not without changes. DRW wheels use different offsets and spacing requirements. Confirm with the calculator, measure dual spacing, and verify load ratings and clearance before attempting any swap.
