2019 Dodge Tire Fitment Guide

2019 Dodge vehicles use eight tire sizes across the Challenger and Charger: 235/55R19, 245/45R20, 275/40R20, 305/35R20, 235/55R18, 225/60R18, 245/55R18, and 215/65R17. Challenger uses 235/55R19, 245/45R20, 275/40R20, 305/35R20, and 235/55R18. Charger uses 245/45R20, 225/60R18, 245/55R18, 275/40R20, 235/55R19, and 215/65R17. Published rim-width guidance appears on some 20-inch and 18-inch products, including 7.5 to 9.0 inches for 245/45R20, 9.0 to 11.0 inches for 275/40R20 depending on tire, 10.0 to 12.0 inches or 11 inches for 305/35R20, and 18-inch rim diameter for 245/55R18.

The practical takeaway is that 2019 Dodge fitment depends on more than year and make. Challenger and Charger do share some sizes, but several sizes belong to one model only, and wheel diameter ranges from 17 to 20 inches across the lineup. Start by checking the size already on the sidewall and confirming the wheel diameter on the car. That narrows the correct choices quickly and helps avoid ordering a tire that matches the brand and model family but not the actual wheel package.

On a 2019 Dodge, 245/45R20 is a metric radial size. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, the R means radial construction, and 20 is the wheel diameter in inches. This size appears on both the Challenger and Charger, and available products in this size use blackwall styling. Where rim-width guidance is published, 245/45R20 fits wheels from 7.5 to 9.0 inches wide.

That code matters because it tells you both the physical tire proportions and the wheel diameter the tire is built for. A 245/45R20 cannot substitute for an 18-inch or 19-inch size without changing wheels, and even within the same 20-inch diameter you still need the correct width and profile. On a 2019 Dodge, this is one of the easier sizes to recognize because it is shared across both model lines, but it still needs to match the wheel actually fitted to the car.

No. 2019 Dodge Challenger and Charger share 235/55R19, 245/45R20, and 275/40R20, but each model also has unique sizes. Challenger alone uses 305/35R20 and 235/55R18, while Charger alone uses 225/60R18, 245/55R18, and 215/65R17. That means there is no single tire size that covers every 2019 Dodge model or every wheel package within those models.

For a buyer, that makes model identification the first checkpoint rather than an afterthought. Once you know whether the car is a Challenger or Charger, the next step is confirming the wheel diameter and the exact sidewall size already on the vehicle. Shared sizes can simplify shopping, but the model-specific sizes are where mistakes happen most often. If the car has been modified, use the actual wheel-and-tire combination on the car instead of assuming the standard size for the model family.

Sidewall style on 2019 Dodge tires varies by size. The 245/45R20 and 275/40R20 products are blackwall only. The 305/35R20 size adds a choice between blackwall and raised white letter styling, while 245/55R18 is available with a redline sidewall. Those sidewall treatments create a very different look even when the wheel diameter and basic fitment are correct.

Choosing the sidewall is mostly a question of appearance and how you want the car to present itself. A blackwall keeps a modern, understated look that suits most late-model performance applications. Raised white letters bring a more aggressive muscle-car visual cue, and a redline can lean into a custom or heritage-inspired style. Before making that decision, confirm that the sidewall treatment you like is offered in the exact size your 2019 Dodge uses, since sidewall options are not uniform across all sizes.

2019 Dodge fitments in the available sizes come from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. In 245/45R20, the choices come from BFGoodrich and Nitto. In 275/40R20, they come from M&H Racemaster, BFGoodrich, and Nitto. In 305/35R20, they come from M&H Racemaster, BFGoodrich, Nitto, and Pro-Trac, while 245/55R18 appears from BFGoodrich.

Brand choice matters because each maker tends to serve a slightly different buyer. Some options are oriented toward mainstream street performance, while others are more specialized in appearance or drag-focused use. The best approach is to narrow by your exact size first, then compare the brands that exist within that size rather than starting from the badge on the sidewall. That keeps the search centered on fitment and intended use instead of making assumptions across the whole 2019 Dodge range.

In 245/45R20 for a 2019 Dodge, both BFGoodrich and Nitto offer blackwall radial tires on 20-inch rims. BFGoodrich options include W-rated choices to 168 mph and Y-rated choices to 186+ mph, with published rim-width guidance of 7.5 to 9.0 inches and load figures around 1,929 to 1,930 pounds at 50 psi on products where that information appears. The Nitto NT555 G2 in this size is W-rated to 168 mph and weighs 30.38 pounds.

That means the choice is less about basic fitment and more about the specific character of the tire within the same size. A buyer comparing these should look at the speed rating, the published rim-width range, and whether the intended use is regular street driving or a more performance-focused setup. Since both brands sit in the same 245/45R20 envelope, the smart move is to match the tire’s published spec to the wheel and to how the 2019 Dodge is actually driven.

Published rim-width guidance on 2019 Dodge tire options varies by size. In 245/45R20, products fit 7.5 to 9.0-inch wheels. In 275/40R20, some products call for a 9-inch wheel while others span 9.0 to 11.0 inches. In 305/35R20, one product uses an 11-inch wheel and another spans 10.0 to 12.0 inches. Rim-width guidance is tire-specific, not just size-specific, so the exact product matters.

That matters most when a car has aftermarket wheels or when you are switching among performance-oriented tires in the same nominal size. Two tires that both say 275/40R20 may not carry the same approved wheel-width range. Before fitting a tire on a 2019 Dodge, compare the wheel width on the car to the individual tire’s published range rather than assuming every product in that size mounts the same way. That extra check is especially important with the wider 20-inch fitments.

2019 Dodge applications here are all radial sizes, and tubeless marking varies by product in some cases. One 305/35R20 BFGoodrich product is explicitly marked TL, while several other tires in the same family of 20-inch sizes do not carry a tube marking in the size description. That means tube status should be confirmed on the exact tire being chosen rather than assumed across every product in a given size.

On a modern Dodge wheel, the usual expectation is a tubeless setup, but the tire’s own sidewall marking and the wheel’s condition still need to agree. If the car is using factory-style late-model wheels, the key concern is making sure the chosen tire’s construction and marking match the wheel and valve setup already in service. Any time the size description, product description, or wheel history raises a question, verify before mounting rather than discovering a mismatch at installation.

Original 2019 Dodge wheels cannot be treated as universal across all eight tire sizes because the lineup spans 17-inch, 18-inch, 19-inch, and 20-inch rim diameters. A 20-inch wheel can only use the 20-inch sizes, a 19-inch wheel needs 235/55R19, an 18-inch wheel must stay with one of the 18-inch sizes, and a 17-inch wheel uses 215/65R17. Diameter compatibility comes first before any question of width or brand.

Within a single diameter, wheel width is the next checkpoint. That is especially relevant on the 20-inch applications, where published rim-width recommendations differ among 245/45R20, 275/40R20, and 305/35R20 products. If a 2019 Dodge still has its original wheels, the current sidewall size is usually the clearest guide. If the car has aftermarket wheels, measure or verify the wheel width before moving to a wider or lower-profile replacement tire.

A stored 2019 Dodge should be kept away from direct sunlight, standing moisture, and ozone-producing equipment such as electric motors, welders, and some battery chargers. Tires hold up best when they are clean, properly inflated, and not left supporting the full vehicle weight in one position for very long periods. Even though these are radial applications rather than old-style bias-ply tires, long static storage can still create temporary flat-spotting and accelerate age-related sidewall deterioration.

For longer storage, move the car periodically or support it in a way that reduces continuous load on one contact patch, while still following safe lifting practice. Keep the garage temperature as stable as possible and avoid parking on bare earth or damp concrete. When the 2019 Dodge comes back into service, inspect each tire for cracking, deformation, and pressure loss before the first real drive rather than assuming a low-mile collector car is automatically road-ready.

Tire life on a 2019 Dodge is better judged by age and condition than by mileage alone, especially on cars that see seasonal or weekend use. A sensible rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat around ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall is the quickest way to determine the tire’s actual age.

Performance-oriented cars often accumulate fewer miles than daily drivers, which can make an older tire look serviceable long after the rubber has begun to harden. Heat cycles, storage conditions, and inflation history all matter. On a 2019 Dodge, that is especially important if the car is used for spirited driving, highway travel, or occasional events rather than routine commuting. Tread depth alone is not enough; age, cracking, and ride quality all deserve equal attention.

Tires on a 2019 Dodge should be inspected before every drive and again before any longer highway outing. Look for cuts, bulges, abnormal shoulder wear, punctures, embedded debris, and sidewall cracking, and confirm that all four tires are holding the intended pressure. On wide 20-inch performance sizes, uneven wear can also signal alignment or suspension issues that deserve attention before the tire itself is blamed.

A quick pre-drive walkaround catches many problems early, especially on cars that are not driven every day. Monthly pressure checks are a good baseline, but a visual inspection should happen more often than that. If the car has been parked for weeks, pay extra attention to flat spots or a tire that appears lower than the others. The spare, if carried, also deserves the same age and condition review before trusting it on the road.

2019 Dodge tires in these available sizes can be suitable for highway driving when the tire’s condition, size, and speed rating match the way the car is used. Among the published ratings, W-rated tires carry a ceiling of 168 mph and Y-rated tires carry a ceiling of 186+ mph. Some sizes, such as 275/40R20 and 305/35R20, also include more specialized performance-oriented products, so the exact tire matters just as much as the size itself.

For normal highway use, a healthy tire in the correct size is usually a more important safety factor than chasing the highest possible speed symbol. The broader condition of the car still matters too, including alignment, brakes, suspension, and inflation pressure. Before relying on any 2019 Dodge for sustained highway travel, confirm that the tire is not aged out, damaged, or mismatched side to side. A high speed rating does not override poor condition or an incorrect fitment.

Inflation pressure on a 2019 Dodge should follow the vehicle placard or owner’s manual for the specific model and wheel package, not a one-size-fits-all number. Tire pressure figures shown on some products are load-related maximums rather than vehicle-specific operating recommendations. For example, some 245/45R20 and 275/40R20 products show load capacity at 50 psi, but that does not mean every 2019 Dodge using those sizes should be run at 50 psi.

Use the factory recommendation as the baseline for street driving, then compare it with the tire manufacturer’s published limits for the exact tire you choose. If the car has aftermarket wheels or a non-original tire size, be more careful about assuming the door-jamb number still applies without adjustment. The safest habit is to check pressure cold, recheck it regularly, and keep all four tires matched to the intended setup rather than inflating by appearance alone.

Before a longer drive in a 2019 Dodge, inspect each tire for cracking, cuts, bulges, punctures, and irregular wear, then confirm cold inflation pressure and tread condition. Also check the valve stems, the age of the tires, and the condition of the spare if the car carries one. On 20-inch performance sizes, it is wise to confirm that the tires are evenly worn and that there is no rubbing or clearance issue at full steering lock or suspension travel.

Tires are only one part of the pre-trip picture, but they are the easiest place to catch a problem before it turns into a roadside issue. A longer drive also deserves a broader mechanical check that matches the car’s use, including brakes, fluids, lights, and battery health. If the 2019 Dodge has been parked for a while, take a short local drive first to feel for vibration, flat spotting, or pull before committing to a full highway run.
