The 1998 Dodge Trucks Ram 3500 sits squarely in the era when heavy-duty pickups were expected to tow, haul, and work hard without giving up everyday road manners. In dual-rear-wheel form, this Ram 3500 is valued for its straightforward capability and its place in late-1990s diesel and gas truck culture. For this exact truck, the primary tire fitment is a 215/85R16 radial on a 16-inch rim, giving owners a modern metric size rather than an older bias-ply format. That keeps the decision focused on matching the correct size and wheel setup, especially on DRW trucks. The right choice starts with preserving proper fitment, load-carrying confidence, and clearance for the truck as it is actually equipped.
Which Tire Size Is Right for The 1998 Dodge Trucks Ram 3500
The 1998 Dodge Trucks Ram 3500 uses one primary tire size: 215/85R16 radial on a 16-inch rim. Both covered dual-rear-wheel sub-models use that same fitment, so the main decision is not between multiple primary sizes but making sure the tire matches the truck's wheel setup, intended use, and overall condition before road use.
215/85R16 is a metric radial size in which 215 identifies the nominal section width in millimeters, 85 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On the 1998 Dodge Trucks Ram 3500, this modern radial format suits a heavy-duty pickup that depends on stable highway behavior and proper wheel compatibility. Because this is a straightforward modern size rather than a vintage alphanumeric or numeric bias-ply code, selection usually centers on confirming the exact wheel arrangement and overall tire condition. It is the fitment to evaluate when keeping the truck in its intended 16-inch tire sizing.
Tire fitment is straightforward across the covered 1998 Dodge Trucks Ram 3500 sub-models, with both dual-rear-wheel configurations using the same 215/85R16 radial size. Checking the exact sub-model still matters because DRW trucks should always be matched to the correct wheel and rear-wheel arrangement before replacement.

Frequently Asked Questions
These FAQs focus on 215/85R16 fitment, 16-inch rim compatibility, dual-rear-wheel considerations, and the practical checks that matter before putting a 1998 Dodge Trucks Ram 3500 back into regular road or work use.
Tire Size & Fitment
What tire size fits a 1998 Dodge Trucks Ram 3500?
The covered 1998 Dodge Trucks Ram 3500 dual-rear-wheel models use a 215/85R16 radial tire. That size applies to both the 4x2 (DRW) and 4x4 (DRW) versions, so the primary fitment question is straightforward for these configurations.
Even with one primary size, it is still important to confirm the truck's actual wheel setup before replacement. A work truck may have had wheel, suspension, or axle-related changes over time, and on a DRW Ram 3500, the tire choice needs to match the existing 16-inch wheel arrangement and the truck's intended hauling or road-use demands.
What size rim does a 1998 Dodge Trucks Ram 3500 use?
The 1998 Dodge Trucks Ram 3500 fitment covered here uses a 16-inch rim with the 215/85R16 tire size. In that size code, the final number, 16, is the wheel diameter in inches and is a key part of matching the tire correctly.
Rim diameter should be confirmed at the truck itself before mounting replacement tires, especially on an older heavy-duty pickup. A truck that has seen fleet service, towing duty, or aftermarket wheel changes may no longer be wearing its original wheel setup, and DRW applications also need the correct wheel arrangement maintained from side to side and axle to axle.
Do all 1998 Dodge Trucks Ram 3500 sub-models use the same tire size?
The covered sub-models do. Both the 1998 Dodge Trucks Ram 3500 4x2 (DRW) and 4x4 (DRW) use the same 215/85R16 radial tire size, so there is no split fitment between those two configurations.
That shared size simplifies replacement, but the truck should still be checked carefully before ordering tires. Dual-rear-wheel spacing, wheel condition, and any prior modifications can affect whether the current setup still matches the intended fitment, so it helps to confirm the mounted wheel diameter and overall rear-wheel arrangement rather than relying on age alone.
Choosing the Right Tire
What should I consider when choosing a 215/85R16 tire for a 1998 Dodge Trucks Ram 3500?
Start with the correct 215/85R16 size and make sure the tire is appropriate for the truck's 16-inch wheel setup. On a 1998 Dodge Trucks Ram 3500 DRW, the decision is less about sorting through multiple primary sizes and more about preserving the fitment the truck was built around.
A good selection process also includes checking the actual wheel arrangement, the condition of the rims, and how the truck is used today. A Ram 3500 that spends time towing, hauling, or sitting for long periods should have its tire condition, age, and air retention reviewed carefully so the replacement matches both the truck's setup and its workload.
How do I choose between the available 215/85R16 tires for a 1998 Dodge Trucks Ram 3500?
Use fitment as the first filter. Any tire under consideration should match the 215/85R16 size and the truck's 16-inch wheel diameter, since that is the core fitment for the covered 1998 Dodge Trucks Ram 3500 DRW models.
From there, focus on practical details such as the truck's present use, the condition of the wheels, and whether the setup remains stock. A truck that still sees regular hauling needs different priorities than one used occasionally, but in both cases the smarter approach is to keep the size correct and verify clearance, dual-wheel spacing, and overall condition before returning the truck to service.
What rim-fitment details should I compare when choosing tires for a 1998 Dodge Trucks Ram 3500?
The most important rim-fitment point is matching the tire to the truck's 16-inch wheel diameter. Because the 1998 Dodge Trucks Ram 3500 covered here uses 215/85R16 tires, the wheel must match that diameter before any replacement tire is considered.
Beyond diameter, the wheel setup should be inspected for condition and consistency, especially on a DRW truck. Bent wheels, mixed wheel types, or prior changes to the truck can affect how the tires sit and how much clearance exists between duals, so checking the actual mounted wheels is just as important as choosing the right size on paper.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Dodge Trucks Ram 3500?
A period-style starting point for the covered 1998 Dodge Trucks Ram 3500 is the original fitment size itself: 215/85R16 radial on a 16-inch rim. Because this truck uses a modern metric radial format, preserving that size is usually the clearest way to keep the overall look and stance in character with the truck's late-1990s heavy-duty appearance.
Appearance should still be balanced with the truck's actual wheel setup and use. A restoration-minded owner may want the truck to look right at a glance, while a work-oriented owner may care more about service readiness, but both goals start with the proper size and a careful check of wheel condition, ride height, and tire age.
Does correct tire fitment matter for a 1998 Dodge Trucks Ram 3500 restoration?
Yes, correct tire fitment has a major effect on how a restored 1998 Dodge Trucks Ram 3500 looks and functions. Keeping the covered DRW truck in its 215/85R16 radial size helps preserve the proportions, wheel-to-tire relationship, and heavy-duty visual character that belong to this generation of Ram 3500.
Fitment also matters mechanically, not just visually. Restorations often involve fresh paint, suspension work, and wheel refinishing, so the tire choice should be checked against the actual finished setup before road use. That is especially important on a dual-rear-wheel truck, where spacing, wheel matching, and overall clearance need to remain consistent after the build is complete.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Dodge Trucks Ram 3500?
Yes, modifications can affect tire fitment on a 1998 Dodge Trucks Ram 3500 even when the intended tire size remains 215/85R16. Wheel changes, suspension work, altered ride height, or other chassis modifications can change how the tire sits in relation to the truck and how much clearance is available.
That matters even more on a DRW truck, where the full wheel arrangement needs to work together correctly. A Ram 3500 with aftermarket wheels or suspension changes should be checked for wheel diameter, dual-wheel spacing, steering clearance, and any signs of rubbing before replacement tires are put into regular use.
What should I inspect before driving a 1998 Dodge Trucks Ram 3500 on new tires?
Begin with the basics: confirm the tires are the correct 215/85R16 size, inspect the wheels for damage, and make sure the tires are mounted on the proper 16-inch rims. It also helps to look over valve stems, wheel hardware, and the general condition of the truck's suspension and steering components.
A heavy-duty pickup deserves a closer walk-around before road use, especially if it has been sitting. Check inflation, look for any visible interference, and inspect older components for cracking, looseness, or uneven wear patterns that could point to alignment or suspension issues. On a DRW Ram 3500, make sure the rear-wheel arrangement is consistent and free from clearance problems.
How should 215/85R16 tires on a collector 1998 Dodge Trucks Ram 3500 be maintained?
Collector-use tires on a 1998 Dodge Trucks Ram 3500 still need regular attention even if the truck is driven only occasionally. The 215/85R16 tires should be checked for proper inflation, visible sidewall cracking, tread condition, cuts, bulges, and any gradual air loss that can go unnoticed during long storage periods.
Storage conditions matter just as much as mileage. Keeping the truck away from prolonged sunlight, excess moisture, and ozone sources helps protect the tires, while periodic inspection helps catch age-related problems before a longer drive. On a DRW truck, it is also wise to look at spacing and wear patterns across the full rear-wheel setup rather than checking only the outer tires.
