2014 RAM Trucks Tire Fitment Guide

2014 RAM Trucks vehicles use eight sizes across nine models: 275/60R20, 265/70R17, and 285/45R22 for the 1500; 275/70R18, 285/60R20, 285/70R17, and 245/70R17 for the 2500; and 275/70R18, 285/60R20, and 235/80R17 for the 3500 range, with the Tradesman using 275/70R18 and 235/80R17. The active product range here covers 17- and 18-inch applications, with rim-width guidance of 7.0 to 9.0 inches for 265/70R17, 7.0 to 9.0 for 275/70R18, 7.5 to 9.5 for 285/70R17, 6.5 to 8.0 for 245/70R17, and 6.0 to 7.5 for 235/80R17.

The practical takeaway is that 2014 RAM Trucks do not share one universal tire size. Start by identifying whether your truck is a 1500, 2500, or 3500, then confirm whether it carries a 17-, 18-, 20-, or 22-inch wheel package. That step narrows the field much faster than comparing tread patterns first, and it prevents crossing over into a size that belongs to a different duty class or wheel diameter.

On a 2014 RAM Trucks tire, 265/70R17 is a metric radial size. The 265 is the nominal section width in millimeters, 70 is the aspect ratio, the R indicates radial construction, and 17 is the wheel diameter in inches. On this year of RAM, that size is used on the 1500 rather than the heavier 2500 or 3500 models.

Understanding that code helps you separate tire diameter and wheel diameter from appearance alone. A 265/70R17 and a 275/60R20 can look similar at a glance on a truck, but they do not fit the same wheel. If your 2014 RAM Trucks 1500 wears a 17-inch factory wheel, 265/70R17 is the code to confirm on the sidewall before comparing load version, speed rating, or sidewall style.

No, 2014 RAM Trucks models do not use the same tire size. The 1500 has three model-specific sizes, the 2500 shares 275/70R18 and 285/60R20 with much of the 3500 range but also has its own 285/70R17 and 245/70R17 fitments, and the 3500 lineup commonly uses 275/70R18 or 235/80R17, with some trims also using 285/60R20. That spread reflects different wheel packages and different truck roles within the RAM lineup.

For a buyer, that means year and make are only the starting point. The same 2014 RAM Trucks badge covers a half-ton pickup, a three-quarter-ton truck, and several one-ton trims, each with different wheel diameters and tire proportions. If you are unsure which version you have, checking the current sidewall code and wheel size on the truck will usually answer the fitment question more quickly than comparing trim names alone.

2014 RAM Trucks tires here come in two sidewall styles: RWL and RBL. The 265/70R17, 275/70R18, 285/70R17, and 245/70R17 BFGoodrich options use raised white letters, while the 235/80R17 BFGoodrich option uses a raised black letter sidewall. That means sidewall appearance can differ even when the tires are all modern radial truck designs.

The choice matters mostly for appearance. Raised white letters give a more aggressive, aftermarket truck look that many owners prefer on 1500 and 2500 builds, while raised black letters tend to look more subdued on work-focused heavy-duty trucks. If visual authenticity matters to you, match the sidewall style to how your 2014 RAM Trucks is being restored or presented, instead of treating sidewall lettering as an afterthought.

BFGoodrich covers the active 2014 RAM Trucks sizes here, with All-Terrain T/A KO2 products in 265/70R17, 275/70R18, 285/70R17, 245/70R17, and 235/80R17. Those are all radial light-truck tires and they span both lighter-duty and heavy-duty RAM applications. The sidewall appearance depends on size, with most using RWL and 235/80R17 using RBL.

That concentration around one well-known all-terrain line simplifies the decision if you want a consistent brand family across trucks of different duty levels. The next step is not choosing by brand first, but confirming the exact size your 2014 RAM Trucks uses and then comparing the available load version and speed rating inside that size. That approach is especially important in the 265/70R17 and 285/70R17 ranges, where the available specs are not identical.

The biggest differences within the BFGoodrich All-Terrain T/A KO2 range for 2014 RAM Trucks are load version, inflation pressure, speed rating, and approved rim-width range. In 265/70R17, one KO2 is rated 2,470 lbs at 50 psi and another is rated 3,195 lbs at 80 psi, both with an S speed rating. In 285/70R17, one version carries a 116Q marking with 2,755 lbs at 50 psi, while another carries a 121/118R marking with 3,195 lbs at 80 psi. Weights vary too, from 45.7 to 53.5 pounds in 265/70R17 and 50.3 to 58.2 pounds in 285/70R17.

Those differences matter most if your 2014 RAM Trucks sees real payload, towing, or rough-service use. A lighter-duty version may suit a truck that spends more time unloaded, while a higher-load version aligns better with heavier service when the wheel and application support it. Compare the sidewall markings on your current tires and verify the wheel width before choosing, because the tire code alone does not tell the whole story within the same nominal size.

Rim-width guidance for 2014 RAM Trucks tires varies by size. The 265/70R17 fits 7.0 to 9.0-inch rims, 275/70R18 fits 7.0 to 9.0-inch rims, 285/70R17 fits 7.5 to 9.5-inch rims, 245/70R17 fits 6.5 to 8.0-inch rims, and 235/80R17 fits 6.0 to 7.5-inch rims. Those ranges are not interchangeable just because two tires share the same 17-inch rim diameter.

This matters most on 2500 and 3500 trucks, where several 17-inch sizes appear across the lineup. A wheel that accepts 235/80R17 may not be the best match for 285/70R17, even though both mount on a 17-inch rim. If you are moving away from the size currently on your 2014 RAM Trucks, confirm the actual wheel width before changing tire dimensions so the tire and rim work together as intended.

The 2014 RAM Trucks radial products here do not carry tube-type markings in their size descriptions, and they are modern radial truck tires intended for contemporary wheel applications. That makes them tubeless-style fitments in normal use. None of these sizes are presented as antique or bias-ply tube-type applications.

Even so, the correct setup still depends on the wheel being in good condition and appropriate for tubeless use. On a 2014 RAM Trucks pickup, inspect the bead seats, valve stems, and wheel condition whenever tires are replaced, especially on work trucks that may have seen corrosion or hard service. A tire can be correct in size and still give trouble if the wheel itself is damaged or poorly maintained.

A 2014 RAM Trucks should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that age rubber. Keep the truck on clean pavement or a barrier surface rather than bare dirt, and maintain the tires at proper inflation during storage. Periodic movement helps prevent long-term flat spotting and keeps the casing from sitting under one static load point for too long.

That advice matters even on modern radial truck tires, especially when the vehicle spends long periods parked between uses. Heavy-duty 2500 and 3500 models put significant static load into the tire when stored, so leaving a truck motionless for months can age the tires faster than many owners expect. If the truck will be down for an extended period, inspect the sidewalls before returning it to regular service.

Tires on a 2014 RAM Trucks should be judged by age as much as tread depth. A sound rule for collector and low-mileage use is to begin careful evaluation around five to seven years and consider replacement around ten years, even if the tread still looks strong. The DOT date code on the tire sidewall is the quickest way to confirm age.

That matters because many trucks age out their tires before they wear them out. A lightly used 2014 RAM Trucks may still look fine in the driveway while the rubber has hardened, cracked, or lost flexibility over time. If the truck tows, hauls, or sees highway use, aging becomes even more important, since load and heat put greater stress on an older tire than casual around-town driving does.

Tires on a 2014 RAM Trucks deserve a visual inspection before every drive and a more careful check before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, and signs of impact damage, and confirm that each tire is holding the expected air pressure. On working trucks, also check for punctures or tread damage from gravel, jobsite debris, or curb contact.

Regular inspection is especially important because 2014 RAM Trucks can range from lightly used personal pickups to heavy-duty haulers. A tire that looks acceptable from a few feet away may still show shoulder wear, age cracking, or bead damage when examined closely. Catching those issues early is far easier than dealing with them after the truck is loaded, towing, or already out on a longer highway run.

A 2014 RAM Trucks 1500 used modern radial tires from new, not bias-ply construction. Within this year and make, the 1500 appears with 265/70R17, 275/60R20, and 285/45R22 depending on configuration, which reflects how modern full-size pickups often varied tire size by wheel package and trim direction. The exact original brand could differ by build and market.

If authenticity matters, the goal is to match the original size format, wheel diameter, and sidewall character that suit your truck's factory-style configuration. Because 2014 RAM Trucks used several different 1500 fitments, a quick sidewall check on the truck or a factory equipment reference is more useful than assuming every 1500 left the factory on the same size. For show-level accuracy, a RAM specialist or marque forum can help confirm the original combination.

Correct tire fitment does matter when presenting a 2014 RAM Trucks in judged or detail-oriented settings. Judges and knowledgeable enthusiasts often notice whether the truck wears the right overall size, the correct wheel diameter, and a sidewall appearance that matches the truck's intended character. On a modern truck, an obviously wrong wheel-and-tire combination can stand out as quickly as an incorrect trim badge.

That does not mean every show demands one exact brand or tread pattern, but it does mean a 17-inch work-truck size should not be confused with a 20- or 22-inch appearance package. A well-matched tire supports the whole presentation of a 2014 RAM Trucks, especially when the truck is otherwise restored or carefully preserved. Event standards vary, so marque groups and model-specific communities remain the best source for judging expectations.

On the 2014 RAM Trucks 2500, BFGoodrich All-Terrain T/A KO2 options differ meaningfully by size and by the exact version within a size. The 245/70R17 KO2 carries a 3,000-lb rating at 80 psi on a 6.5 to 8.0-inch rim, while 275/70R18 reaches 3,640 lbs at 80 psi on a 7.0 to 9.0-inch rim. Within 285/70R17, one version is a 116Q rated 2,755 lbs at 50 psi and another is a 121/118R rated 3,195 lbs at 80 psi.

For a restoration-minded owner, those differences matter because they affect how closely the tire matches the truck's intended stance, wheel package, and service role. A 2500 kept close to factory character should stay within the correct size family for its wheel diameter, then use the load version that best reflects how the truck will actually be driven. Matching the nominal size alone is not enough when several KO2 variants carry different working specifications.

Yes, the radial 2014 RAM Trucks tires here are highway-capable when they are in good condition, correctly inflated, and matched to the truck's actual use. Speed ratings in these sizes include Q up to 99 mph, R up to 106 mph, and S up to 112 mph, depending on the exact tire. The 275/70R18 carries an R rating, 245/70R17 and 235/80R17 carry S ratings, and 285/70R17 varies between Q and R.

The bigger concern on a full-size pickup is usually condition, loading, and overall truck setup rather than raw speed rating alone. A 2014 RAM Trucks 2500 or 3500 towing or hauling on aging, underinflated, or overloaded tires is a much more serious issue than whether the tire's speed ceiling exceeds normal interstate pace. Confirm the sidewall code on your exact tire, then match your cruising speed and load to that specific tire's rating.

Inflation pressure on 2014 RAM Trucks tires depends on the exact size and version. Available figures include 265/70R17 at either 50 psi for a 2,470-lb version or 80 psi for a 3,195-lb version, 275/70R18 at 80 psi for 3,640 lbs, 285/70R17 at either 50 psi for 2,755 lbs or 80 psi for 3,195 lbs, 245/70R17 at 80 psi for 3,000 lbs, and 235/80R17 at 80 psi for 3,085 lbs. Those are tire ratings, not universal truck settings.

Use the truck manufacturer's recommendation for the specific axle load and configuration as your starting point, then verify that the tire you choose supports that use. Do not transfer a pressure number from one 2014 RAM Trucks size to another just because the trucks look similar. Differences in load version, wheel package, and front-versus-rear duty can change the correct working pressure substantially.

Before a longer drive in a 2014 RAM Trucks, inspect every tire for cracking, cuts, punctures, bulges, and uneven wear, and check air pressure when the tires are cold. Make sure the spare is usable and inflated, and look closely at valve stems and wheel condition. On heavy-duty trucks, pay extra attention to signs of overload wear or sidewall stress if the truck tows or carries weight regularly.

Tires are only one part of a smart pre-trip inspection on a full-size pickup, but they are the part in constant contact with the road. A 2014 RAM Trucks that appears ready for a trip can still have aged rubber, a marginal spare, or a damaged tire from previous work use. Catching those issues before departure is especially worthwhile on a 2500 or 3500, where load and heat can magnify small tire problems quickly.
