2015 RAM Trucks 3500 Tradesman Tires

The 2015 RAM Trucks 3500 Tradesman uses either 275/70R18 or 235/80R17, depending on the truck's exact configuration. The 275/70R18 size belongs to the 4x2 and 4x4 single-rear-wheel models, while the 235/80R17 size is used on the 4x2 (DRW) and 4x4 (DRW) versions.

That means the first step is identifying whether the truck is SRW or DRW before looking at products. Wheel diameter matters just as much as the tire size itself, so confirm the truck still has the correct 17-inch or 18-inch wheels if it has ever been modified or repurposed for different work.

A 2015 RAM Trucks 3500 Tradesman uses either a 17-inch or 18-inch rim, depending on sub-model. Trucks fitted with 275/70R18 tires use an 18-inch rim, while trucks fitted with 235/80R17 tires use a 17-inch rim.

Rim diameter should be confirmed before ordering any replacement tire, especially on a heavy-duty truck that may have seen wheel changes during its service life. It is also worth checking actual wheel width against the tire's approved range, since correct diameter alone does not guarantee that the wheel is the right match.

The 2015 RAM Trucks 3500 Tradesman has more than one tire size because the fitment changes with configuration. Single-rear-wheel 4x2 and 4x4 models use 275/70R18, while dual-rear-wheel 4x2 (DRW) and 4x4 (DRW) models use 235/80R17.

That difference is not just a brand or style choice; it reflects different wheel setups and intended truck layouts. A buyer should confirm the exact sub-model and current wheel package before comparing tires, especially if the truck has had replacement wheels, fleet-service alterations, or other equipment changes over time.

Start with the truck's exact fitment: 275/70R18 for SRW models or 235/80R17 for DRW models. From there, compare construction, approved rim-width range, load specification, and how the tire will be used, since a heavy-duty pickup often sees a mix of unloaded driving, towing, and jobsite conditions.

The available choices here are all radial BFGoodrich All-Terrain T/A KO2 products, so the real selection point is matching the correct size to the truck's actual wheel setup. Sidewall presentation also differs by size, with raised white letter on the 18-inch option and black sidewall on the 17-inch option.

Sidewall style depends on tire size for the 2015 RAM Trucks 3500 Tradesman. The 275/70R18 BFGoodrich All-Terrain T/A KO2 uses RWL styling, while the 235/80R17 version uses RBL styling.

That gives the SRW 18-inch fitment a raised white letter appearance and the DRW 17-inch fitment a black sidewall presentation. Appearance should stay secondary to correct size and wheel compatibility, but sidewall style can still matter for owners who want either a more traditional truck look or a cleaner utility-focused presentation.

BFGoodrich is the available brand for the 2015 RAM Trucks 3500 Tradesman in these fitments. Both the 275/70R18 and 235/80R17 sizes are represented by the BFGoodrich All-Terrain T/A KO2 series in radial construction.

Since the brand choice is narrow here, comparison shifts to the correct size, the truck's wheel setup, and specification details such as rim-width range and load capacity at the stated pressure. That is especially important on a 3500-series truck, where using the right tire format matters more than chasing cosmetic differences alone.

A period-style choice for a 2015 RAM Trucks 3500 Tradesman starts with keeping the correct original-format size for the truck's configuration. That means 275/70R18 for SRW models or 235/80R17 for DRW models, both in radial construction, rather than changing to a different size simply for appearance.

Because this is a modern heavy-duty truck, appearance usually follows utility more than vintage-style detailing. Owners who want the truck to look appropriate for its era should focus on preserving the right wheel diameter, correct stance, and a tire style that suits the truck's working character instead of forcing a mismatched visual theme.

On a 2015 RAM Trucks 3500 Tradesman, tire construction is straightforward because the correct-format fitments are radial. That keeps the truck visually aligned with its era, since modern heavy-duty pickups were built around radial tire proportions and contemporary wheel sizes rather than older bias-ply styling cues.

Appearance is influenced more by size, sidewall treatment, and whether the truck remains on the proper 17-inch or 18-inch wheels. A raised white letter sidewall on the 275/70R18 setup gives a different look than the black sidewall 235/80R17, so the truck's exact configuration shapes the final presentation.

Yes, modifications can affect tire fitment on a 2015 RAM Trucks 3500 Tradesman even when the tire size itself looks close. Wheel changes, suspension lifts or drops, offset changes, and conversions between work setups can alter clearance, wheel compatibility, and the relationship between the tire and the truck's body or steering components.

That matters even more on a 3500-series truck because SRW and DRW models already start with different factory fitments. Any owner dealing with aftermarket wheels or altered ride height should confirm wheel diameter, width, and clearance at full steering and suspension travel before committing to a replacement tire.

Before driving a 2015 RAM Trucks 3500 Tradesman on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then verify that the tire size matches the truck's exact SRW or DRW configuration. It is also wise to look for any signs of rubbing risk around suspension, steering, and body clearances.

A heavy-duty truck puts real demand on its tires, so a quick visual check is not enough. Make sure the wheels are the correct diameter, the tire sits properly on the rim, and there are no brake, alignment, or suspension issues that could shorten tire life once the truck returns to loaded road use.

Tires on a 2015 RAM Trucks 3500 Tradesman should be inspected regularly, with extra attention before towing, hauling, or taking the truck on a longer trip. Heavy-duty use can magnify the effects of low pressure, uneven wear, punctures, cuts, or sidewall damage much faster than on a lightly used passenger vehicle.

Frequent inspection is especially important if the truck sits for stretches and then returns to work. Check tread condition, air retention, and visible sidewall health, and keep an eye on irregular wear that could point to alignment, balance, or suspension problems rather than a tire issue alone.
