2018 Dodge Trucks Tire Fitment Guide

2018 Dodge Trucks vehicles use five sizes across two models. The Durango uses 265/50R20, 265/60R18, and 295/45R20, while the Journey uses 225/55R19 and 225/65R17. Those sizes correspond to 20-inch, 18-inch, 20-inch, 19-inch, and 17-inch wheels respectively, so fitment depends on both the model and the wheel package on the vehicle.

That means there is no single tire size that covers every 2018 Dodge Trucks application. A buyer should confirm the model first, then verify the size already fitted to the vehicle or the factory tire placard before comparing tread designs or brands. That simple check prevents mixing Journey and Durango sizes that may look close on paper but mount on different wheel diameters.

On a 2018 Dodge Trucks tire, 265/50R20 is a metric radial size. The 265 is the nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of the section width, R identifies radial construction, and 20 is the wheel diameter in inches. On this year and make, that size applies to the Durango.

Reading the code correctly matters because a 265/50R20 is not interchangeable with another 20-inch size just because the wheel diameter matches. Width and sidewall profile change the overall fit, look, and driving character. If a 2018 Dodge Trucks Durango already wears 20-inch wheels, matching the exact sidewall code is the safest starting point before moving into brand or tread-pattern decisions.

No, 2018 Dodge Trucks models do not use the same tire size. The Durango and Journey have completely different fitments, and even within each model there can be more than one correct size depending on wheel diameter and package. Durango sizes stay within 18-inch and 20-inch wheel fitments, while Journey sizes use 17-inch and 19-inch wheel fitments.

That is why identifying the model is more important here than on a year-and-make page where every vehicle shares one size. A Durango owner should not assume a Journey size will cross over, and a Journey owner should not rely on make alone. Checking the exact model and the tire size currently on the vehicle will narrow the search quickly and avoid an expensive mismatch.

Sidewall style variety for 2018 Dodge Trucks tires is limited in the summarized product range here. The 225/65R17 Journey size is available with an RBL, or raised black letter, sidewall from BFGoodrich. No broader sidewall-style spread is established across the other four sizes in this year-and-make range, so sidewall appearance should be confirmed on the exact tire selected for each application.

For most 2018 Dodge Trucks owners, sidewall style is more about appearance than authenticity, since these are modern crossover and SUV applications rather than concours-era collector cars. An RBL sidewall gives the tire a more rugged visual character, especially on an all-terrain pattern. If appearance matters, confirm the sidewall description on the exact size you need rather than assuming another size in the range offers the same finish.

BFGoodrich is represented in the current 2018 Dodge Trucks product range through the 225/65R17 Journey fitment, using the All-Terrain T/A KO2 series. That product is a radial tire with an RBL sidewall and an S speed rating. No other brand spread is established across the remaining sizes in this year-and-make range here.

Brand choice becomes more meaningful once the exact model and size are confirmed, because a Journey on 17-inch wheels may have a very different use case from a Durango on 20-inch wheels. A buyer interested in a more aggressive tread look, a highway-oriented pattern, or a specific sidewall treatment should start with the exact size and then compare what exists in that fitment rather than searching by make alone.

For 2018 Dodge Trucks vehicles, the main difference is intended use. The BFGoodrich All-Terrain T/A KO2 available in 225/65R17 for the Journey is built around a more aggressive all-terrain character than a typical road-focused crossover tire, and it carries a 2,150-pound maximum load rating at 65 psi with an S speed rating. That makes it a distinctive option within this year-and-make range rather than a generic passenger-tire replacement.

A buyer should think about where the vehicle actually spends its time. If a 2018 Dodge Trucks Journey is driven mainly on pavement, ride feel, noise, and appearance may steer the decision one way; if rough roads or light trail use matter more, an all-terrain design may be appealing. The key is staying with the exact size and load class that matches the wheel and intended service.

A confirmed rim-width range appears for the 2018 Dodge Trucks 225/65R17 Journey size. That tire fits a 17-inch wheel and is suited to rim widths from 6.0 to 8.0 inches. A wheel-width range is not summarized here for the other four sizes, so the practical fitment anchor across the full year-and-make page remains the exact tire size and wheel diameter.

Rim width matters because two wheels can share the same diameter but still differ in how well they support a given tire section width. Journey owners using 225/65R17 can treat 6.0 to 8.0 inches as the target range for that specific tire. For other 2018 Dodge Trucks sizes, verify wheel specs on the vehicle or through the wheel manufacturer before changing size or moving to an unusually wide or narrow tire design.

The 2018 Dodge Trucks tire range here is radial and modern in format, and the 225/65R17 product summarized does not carry a tube-type marking. That points buyers toward modern tubeless-style fitment rather than the tube-required practice associated with many older collector-vehicle tires. Even so, tire setup still depends on the actual wheel condition and the exact tire chosen.

For a 2018 Dodge Trucks Journey or Durango, the practical step is to inspect the wheel and valve-stem condition at the same time the tire is replaced. A damaged bead seat, corroded wheel, or aging valve stem can create problems even when the tire itself is suitable for tubeless use. Matching a fresh valve stem and confirming wheel condition is the smart finishing step in a modern radial installation.

A 2018 Dodge Trucks vehicle should be stored on clean, properly inflated tires away from direct sunlight, standing moisture, and electric motors or battery tenders that create ozone. Because every size here is a radial, storage concerns center more on air retention, sidewall aging, and avoiding prolonged exposure to heat and UV than on the severe flat-spotting often associated with older bias-ply designs.

If the vehicle will sit for an extended period, move it occasionally to change the contact patch or place it on stands if the storage plan and suspension support points are appropriate. Keep the tires clean, avoid petroleum-based dressings, and recheck pressure before the vehicle goes back on the road. Those habits help preserve ride quality and reduce premature aging on a low-use SUV or crossover.

On a 2018 Dodge Trucks vehicle, tire life should be judged by age and condition as much as by mileage. A good rule is to begin closer inspection once tires reach about five to seven years of age and to treat the ten-year point as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall tells you when a tire was built.

That matters especially for vehicles that are driven lightly, because a tire can age out before it wears out. Cracking, hardening, irregular wear, or persistent air loss are more meaningful warning signs than tread depth alone on a low-mileage Journey or Durango. Checking the age code during routine service is one of the easiest ways to catch an old tire before it becomes a road-trip problem.

Tires on a 2018 Dodge Trucks vehicle should be inspected before every drive and again before any longer trip. Look for visible cracking, cuts, punctures, uneven wear, bulges, and pressure loss, and make sure the tread is wearing evenly across the tire. On modern radial applications such as these, pressure consistency and sidewall condition are usually the first clues that something needs attention.

A quick walkaround catches many problems before they become expensive or unsafe. On a daily-driven vehicle, a monthly pressure check is a sensible baseline; on a low-use vehicle, pressure and condition should be checked each time it comes out of storage. If one tire repeatedly loses air or shows unusual shoulder wear, inspect the wheel and alignment rather than replacing the tire blindly.

2018 Dodge Trucks tires in these sizes are modern radial fitments, which are well suited to normal highway use when the tire is in good condition and correctly inflated. The 225/65R17 Journey tire summarized here carries an S speed rating, which corresponds to a 112 mph ceiling. That is comfortably above typical U.S. highway speeds, assuming the tire, vehicle, and loading condition are all appropriate.

Real-world highway safety depends on more than the speed symbol alone. Tire age, inflation pressure, tread condition, suspension wear, and the vehicle’s load all play a major role in how a Journey or Durango behaves at speed. A tire with plenty of tread but advanced sidewall age is still a poor long-drive candidate, so condition and maintenance should carry as much weight as the size code.

Inflation pressure for a 2018 Dodge Trucks tire should follow the vehicle manufacturer’s recommendation for the exact model and size, with the tire’s own maximum-pressure marking understood as a load-rating limit rather than a universal operating target. The 225/65R17 tire summarized here carries a maximum load of 2,150 pounds at 65 psi. That figure belongs to that tire’s rated capacity and should not be transferred to the other sizes.

The best practice is to start with the door-jamb placard or owner’s manual for the specific Journey or Durango, then confirm that the chosen tire’s load capacity aligns with the vehicle’s needs. Pressure should always be checked cold, not after driving. If the vehicle is carrying unusually heavy cargo or being used in conditions outside normal commuting, recheck both the tire maker’s guidance and the vehicle recommendation.

Before taking a 2018 Dodge Trucks vehicle on a longer drive, inspect all four tires and the spare for cracking, cuts, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the tire size matches the wheel package on the vehicle and that the tread depth is suitable for the conditions ahead. On a Journey or Durango that has sat for a while, age and air retention deserve special attention.

A longer-drive check should also include valve stems, lug-nut security, and the general mechanical condition of the vehicle. Tires are only one part of the equation on a road trip, but they are the easiest place to catch trouble early. If any tire shows sidewall damage, repeated pressure loss, or obvious age cracking, replace or evaluate it before trusting the vehicle on extended highway miles.
