The 2018 RAM Vans ProMaster 1500 is a front-wheel-drive cargo van built for urban delivery work, contractor duty, and commercial hauling where load stability and predictable road manners matter every day. Its tall-roof, cab-forward design makes tire choice more than a cosmetic decision, because the van’s stance and carrying role put real importance on correct size and wheel compatibility. This ProMaster 1500 uses a 225/75R16 radial tire on a 16-inch rim across its covered fitments. Available choices here focus less on multiple sizes and more on selecting the right construction details, load-oriented specifications, and sidewall style for the van’s intended use and current wheel setup.
Which Tire Size Is Right for The 2018 RAM Vans ProMaster 1500
The 2018 RAM Vans ProMaster 1500 uses one primary tire size: 225/75R16. It is a radial fitment on a 16-inch rim, and that same size carries across the covered wheelbase and Base configurations. That means the main decision is not choosing between different factory sizes, but selecting the right tire within 225/75R16 based on load specification, sidewall appearance, and the way the van is actually used.
Fit(s): (118 inch wheelbase)(C-Type Tires), (136 inch wheelbase)(C-Type Tires), and Base
Construction: Radial|Rim: 16 in
The 225/75R16 size uses modern metric radial sizing, where 225 is the section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2018 RAM Vans ProMaster 1500, that means a contemporary radial tire matched to a 16-inch rim rather than a vintage bias-ply fitment. The available product choice in this size uses the BFGoodrich All Terrain TA KO2 series with raised white letter sidewalls. This is the size to evaluate when maintaining proper wheel compatibility and load-conscious service for a working or dual-purpose ProMaster 1500.
Tire fitment is straightforward across the covered 2018 RAM Vans ProMaster 1500 sub-models, because each one uses the same 225/75R16 radial size. Checking the exact sub-model still matters as a good confirmation step before comparing tires, especially on vans that may have seen commercial use or wheel changes.

2018 RAM Vans ProMaster 1500 (118 inch wheelbase)(C-Type Tires)
The 118-inch wheelbase C-Type Tires version uses the same 225/75R16 radial fitment as the other covered ProMaster 1500 configurations. Tire selection here centers on choosing the right 16-inch radial specification for the van’s workload, wheel condition, and intended road use rather than sorting through multiple primary sizes.
2018 RAM Vans ProMaster 1500 (136 inch wheelbase)(C-Type Tires)
The 136-inch wheelbase C-Type Tires version also uses 225/75R16 radial tires. Since the primary size stays the same, the practical choice is comparing tire characteristics within that size and confirming the van still has the correct 16-inch wheel setup if it has been modified or upfitted.
The 2018 RAM Vans ProMaster 1500 Base uses the same 225/75R16 radial tire size. That keeps fitment simple, so the focus shifts to selecting a tire that matches the van’s service demands, load expectations, and wheel specifications instead of trying to sort out alternate primary sizes.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2018 RAM Vans ProMaster 1500 Tires for Sale
Available 225/75R16 tires for the 2018 RAM Vans ProMaster 1500 focus on radial construction in the BFGoodrich All Terrain TA KO2 series. The current option uses raised white letter sidewalls and a 16-inch fitment with a 6.0 to 7.0-inch rim-width range.
Common questions for the 2018 RAM Vans ProMaster 1500 usually center on the correct 225/75R16 size, 16-inch wheel fitment, choosing the right radial tire, and checking wheel, load, and condition details before putting the van back into regular road use.
Tire Size & Fitment
What tire size fits a 2018 RAM Vans ProMaster 1500?
The 2018 RAM Vans ProMaster 1500 uses 225/75R16 tires. This is a radial tire size fitted to a 16-inch wheel, and it applies across the covered 118-inch wheelbase, 136-inch wheelbase, and Base versions shown here.
That makes fitment simpler than on vehicles with multiple factory sizes, but it is still worth confirming the van’s actual wheel setup before replacing tires. Commercial vans are often upfitted or serviced repeatedly over time, so checking the installed wheel diameter, wheel width, and overall clearance remains an important step.
What size rim does a 2018 RAM Vans ProMaster 1500 use?
The primary tire fitment for the 2018 RAM Vans ProMaster 1500 uses a 16-inch rim. The 225/75R16 size is built around that wheel diameter, so matching the tire to a true 16-inch wheel is essential.
Wheel diameter is only part of the picture on a working van. Rim width should also be checked, especially if the van has replacement steel wheels, aftermarket wheels, or fleet-service changes. A tire can share the correct diameter and still need width and clearance verification before it is put into service.
Do all 2018 RAM Vans ProMaster 1500 sub-models use the same tire size?
The covered 2018 RAM Vans ProMaster 1500 sub-models all use the same 225/75R16 radial tire size. That includes the 118-inch wheelbase C-Type Tires version, the 136-inch wheelbase C-Type Tires version, and the Base model.
Shared sizing makes replacement easier because the main fitment question is usually not the size itself. The better next step is confirming the wheels currently on the van and comparing tire details such as load specification, rim-width compatibility, and the kind of road or jobsite use the van sees most often.
Choosing the Right Tire
What should I consider when choosing a 225/75R16 tire for a 2018 RAM Vans ProMaster 1500?
Start with the correct primary size, which is 225/75R16 on a 16-inch rim. From there, compare radial construction details that matter on a commercial van, including load capacity, inflation requirements tied to that load rating, rim-width compatibility, and the type of service the van handles.
Appearance may matter less on a ProMaster than on a collector vehicle, but sidewall style and tread character can still influence the final choice. It also helps to consider whether the van spends more time on pavement, mixed surfaces, or heavily loaded duty, then verify that the wheel and suspension setup still matches the intended tire.
What sidewall styles are available for 2018 RAM Vans ProMaster 1500 tires?
The available 225/75R16 option for the 2018 RAM Vans ProMaster 1500 uses an RWL sidewall, which means raised white letters. That gives the tire a more pronounced, off-road-inspired appearance than a plain blackwall commercial tire.
Sidewall style does not change the basic fitment size, but it can change the van’s visual character quite a bit. On a work van, some owners prefer a more understated look, while others like the extra visual contrast. The practical decision should still begin with the correct size, wheel fit, and service requirements.
What brands offer tires for the 2018 RAM Vans ProMaster 1500?
The available tire option for this 2018 RAM Vans ProMaster 1500 fitment comes from BFGoodrich. It is offered in the 225/75R16 size and uses radial construction for the van’s 16-inch wheel application.
When the brand selection is narrow, the comparison shifts toward the tire’s individual characteristics rather than choosing among several manufacturers. Pay attention to the series, load specification, rim-width range, and intended use so the tire matches how the ProMaster is driven and what it is expected to carry.
Restoration & Appearance
Which tire should I choose for a period-style 2018 RAM Vans ProMaster 1500?
A period-style approach on a 2018 RAM Vans ProMaster 1500 usually means staying with the correct 225/75R16 radial size and keeping the van’s overall stance and wheel fitment close to its original working character. Since this is a modern commercial platform, appearance choices tend to be more subtle than on older collector vehicles.
The safest visual starting point is the correct size on the proper 16-inch wheel, then deciding whether the available tread and sidewall presentation suit the van’s intended look. If originality matters closely, compare the current wheel and tire presentation with vehicle-specific reference material before making an appearance-driven change.
How does tire construction affect the appearance of a restored 2018 RAM Vans ProMaster 1500?
On a 2018 RAM Vans ProMaster 1500, tire construction is already a modern radial fitment, so the appearance difference comes more from tread style and sidewall treatment than from choosing between bias-ply and radial construction. The visible effect is more functional and contemporary than vintage or highly decorative.
That means a restored or cleaned-up ProMaster usually looks most coherent when the tire size remains correct and the wheel fitment stays proportional to the van’s body and ride height. A more aggressive tire design can change the visual tone, but it should still be checked against load needs and wheel specifications first.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 RAM Vans ProMaster 1500?
Yes, modifications can affect tire fitment on a 2018 RAM Vans ProMaster 1500 even when the original size is 225/75R16. Changes such as aftermarket wheels, altered offsets, suspension work, lift or lowering changes, and body upfits can all influence clearance and the way the tire sits in the wheel opening.
A van that still uses the correct nominal tire size may need closer inspection if its wheel or suspension setup has changed. Steering clearance, inner sidewall clearance, and fender space are all worth checking, especially on a working vehicle that may have seen hard service or multiple rounds of fleet maintenance.
What should I inspect before driving a 2018 RAM Vans ProMaster 1500 on new tires?
Before driving a 2018 RAM Vans ProMaster 1500 on new tires, inspect the wheels for damage, confirm the tire size and wheel diameter match, and check that inflation is appropriate for the tire being installed. It is also wise to look over the valve stems, lug hardware, and general wheel condition.
A short road test should follow once the tires are mounted and balanced. Pay attention to vibration, rubbing, unusual steering feel, and any sign of uneven clearance. On a van used for cargo or commercial service, it also helps to recheck pressure and wheel hardware after the first stretch of driving.
How often should tires on a 2018 RAM Vans ProMaster 1500 be inspected?
Tires on a 2018 RAM Vans ProMaster 1500 should be inspected regularly, especially because this model often serves as a working van rather than a lightly used hobby vehicle. Frequent checks for tread wear, air loss, cuts, bulges, and sidewall damage are a smart habit on any vehicle expected to carry cargo.
Inspection intervals should become even shorter if the van sees jobsite use, curb contact, heavy loads, or long periods parked between trips. It is also worth checking for uneven wear that could point to alignment or suspension issues, since those problems can shorten tire life even when the size itself is correct.
