2019 Ford F350 Tire Size

Q: Can I fit winter tires in a different size on my 2019 Ford F350?

Yes — the standard winter-tire fitment pattern is one width step narrower than OEM (e.g. 225 → 215) with the aspect ratio bumped up to preserve overall diameter. Narrower tires increase contact pressure on snow for better traction. The Compatible alternative sizes table includes any winter-friendly options that fall within ±3% OD for this vehicle.

Check a different size against this vehicle

Type any tire size below; we'll compute its overall-diameter delta against the OEM 275/65R18 and verdict using the ETRTO ±3% rule.

Common upgrade paths

Plus-1: 255/65R19; one rim size up, -0.07% OD change. Sharper steering, mild ride penalty, modest cost premium.
Plus-2: 255/60R20; two rim sizes up, -0.09% OD change. Noticeable ride penalty, higher pothole risk, meaningful tire-cost premium.

Use the plus-size calculator to evaluate any rim step against the OEM size.

How to choose tires for the 2019 ford F350 xlt-4wd

The 2019 Ford F350 XLT-4wd ships from the factory on 275/65R18 tires mounted on R18 wheels. 2 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.

Tire choice on the Ford F350 comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number), speed rating (must match or exceed the placard), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.

For 2019 Ford F350 XLT-4wd owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.

Before purchasing, verify the tire size on the driver-door placard of your specific 2019 Ford F350 XLT-4wd, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

I WAS EAST BOUND ON INTERSTATE 8 EAST OF ALPINE, CA PULLING A TRAILER UP A 6% GRADE. I NOTICED SMOKE FROM THE REAR OF THE TRUCK. I PULLED ONTO THE SHOULDER OF THE ROAD TO INVESTIGATE. THE SPARE TIRE HAD SHIFTED IN ITS MOUNT NEAR OR AGAINST THE TAIL PIPE. THE TIRE HAD IGNITED AND WAS IN FLAMES. IT IS MOUNTED AGAINST THE BOTTOM OF THE REAR FUEL TANK. I EXTINGUSHED THE FIRE, AND REMOVED THE TIRE FROM THE TRUCK. I HAVE BEEN INFORMED OF 3 OTHER INCIDENTS OF THIS OCCURRING ON OTHER FORD PICKUP TRUCKS SINCE THIS INCIDENT. IN ALL FOUR INCIDENTS, THE TRUCKS WERE PULLING TRIALER UP HILL. MY CONCERN IS THE POSSIBILITY OF THE BURNING SPARE TIRE IGNITING THE FUEL IN THE REAR FUEL TANK. I CAN PROVIDE THE VIN NUMBER LATER IF YOU STILL NEED IT.

What size tires fit a 2019 Ford F350?

The OEM tire size for the 2019 Ford F350 is 275/65R18 mounted on R18 wheels.. Trim levels and option packages can shift the original fitment; confirm against your specific vehicle's driver-door placard before purchase.

Can I run a different tire size on my 2019 Ford F350?

Plus-sizing (larger rim, lower aspect) is possible within ±3% of the OEM overall diameter per the ETRTO safe-fit standard. The Compatible alternative sizes table on this page lists every safe option for the OEM size. Always confirm with the manufacturer or a qualified tire shop before deviating from the placard.

Where can I buy tires for my 2019 Ford F350?

Online tire retailers in our affiliate network carry every size documented for this vehicle. Use the Shop online buttons above to compare prices across them; variance of $20–$40 per tire is common between merchants. The <a href="/tools/tire-install-cost-calculator/">install cost calculator</a> estimates the out-the-door including mount, balance, TPMS, and disposal by state.

What is the recommended tire pressure for the 2019 Ford F350?

The cold-inflation pressure is printed on the driver-door placard of your specific vehicle and varies by trim, tire size, and loaded vs unloaded condition. Typical OEM front and rear pressures fall between 30 and 36 psi for passenger trims and 32–40 psi for SUV/truck variants, but the placard is the authoritative source.

Can I fit winter tires in a different size on my 2019 Ford F350?

Yes; the standard winter-tire fitment pattern is one width step narrower than OEM (e.g. 225 → 215) with the aspect ratio bumped up to preserve overall diameter. Narrower tires increase contact pressure on snow for better traction. The Compatible alternative sizes table includes any winter-friendly options that fall within ±3% OD for this vehicle.

How often should I rotate the tires on my 2019 Ford F350?

Every 5,000–7,500 miles is the typical OEM recommendation for passenger vehicles. AWD vehicles and high-torque trucks benefit from the shorter interval. Documented rotation history is also a tire-warranty prerequisite; most manufacturer treadwear claims require rotation receipts at the warranty inspection.
