The 2008 Dodge Trucks Ram 2500 ST sits in the heavy-duty pickup era when three-quarter-ton trucks were expected to handle real work while still serving as everyday transportation. For owners keeping one on the road, tire choice matters as much for load support and road manners as it does for stance and overall utility. This Ram 2500 ST uses a 245/70R17 radial tire on a 17-inch wheel, and that same primary fitment carries across the covered cab and driveline configurations. Available choices in this size lean toward a modern all-terrain radial with raised white letter styling, so the decision centers on intended use, wheel compatibility, and the condition of the truck itself.
Which Tire Size Is Right for The 2008 Dodge Trucks Ram 2500 ST
The 2008 Dodge Trucks Ram 2500 ST uses one primary tire size: 245/70R17. It is a radial fitment on a 17-inch rim, and it is shared across the covered 4x2 and 4x4 regular cab and quad cab ST configurations. That means the main decision is not between multiple factory-type sizes, but between the available tire style, load-focused specifications, and whether the truck still has its original wheel setup.
A 245/70R17 size uses a 245-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2008 Dodge Trucks Ram 2500 ST, this is the core fitment and it suits the truck's heavy-duty, road-ready character better than an older bias-ply format would. In available products, this size appears in BFGoodrich's All Terrain T/A KO2 with raised white letter sidewall styling. It is the size to focus on when the truck retains its correct 17-inch wheel package and the goal is to preserve proper fitment before comparing tread style and rim-width compatibility.
Tire fitment is straightforward across the covered 2008 Dodge Trucks Ram 2500 ST sub-models because each one uses the same 245/70R17 radial size. Checking the exact sub-model still matters when confirming that the truck has the expected 17-inch wheels and has not been altered with a different wheel or suspension setup.

2008 Dodge Trucks Ram 2500 ST 4x2 Quad Cab
The 2008 Dodge Trucks Ram 2500 ST 4x2 Quad Cab uses the same 245/70R17 radial fitment as the other covered ST configurations. Tire selection can stay focused on correct size, 17-inch wheel compatibility, and whether an all-terrain raised white letter look suits how the truck is actually driven.
The 2008 Dodge Trucks Ram 2500 ST 4x2 Reg. Cab also uses a 245/70R17 radial tire. That keeps fitment simple, so the practical next step is confirming wheel width and overall truck condition before choosing among the available tires in this size.
The 2008 Dodge Trucks Ram 2500 ST 4x4 Quad Cab stays with the same 245/70R17 radial sizing. For this configuration, the important choice is less about size and more about selecting a tire that matches the truck's wheel setup, use on pavement or mixed surfaces, and preferred sidewall presentation.
The 2008 Dodge Trucks Ram 2500 ST 4x4 Reg. Cab shares the 245/70R17 radial fitment used throughout the covered ST lineup. That consistency makes tire shopping easier, but it is still worth verifying that the truck remains on proper 17-inch wheels and has enough clearance if anything has been modified.
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.

Tire Size & Fitment
What tire size fits a 2008 Dodge Trucks Ram 2500 ST?
The 2008 Dodge Trucks Ram 2500 ST uses a 245/70R17 radial tire. That primary size applies across the covered ST configurations, including 4x2 and 4x4 regular cab and quad cab models, so the fitment question is more straightforward here than on trucks that changed size by trim or package.
Correct size is only the starting point on a heavy-duty pickup. It is still important to confirm that the truck is on the proper 17-inch wheels, that wheel width is suitable for the tire being considered, and that no previous owner changed ride height, wheels, or clearance in a way that affects fit.
What size rim does a 2008 Dodge Trucks Ram 2500 ST use?
The primary tire fitment for the 2008 Dodge Trucks Ram 2500 ST is built around a 17-inch rim diameter. That matches the 245/70R17 tire size, where the final number in the size code identifies the wheel diameter the tire is designed to mount on.
Rim diameter should not be confused with rim width, and both matter when selecting a replacement tire. A truck may still wear the correct 17-inch diameter wheel but have a different width or aftermarket design, so checking the actual wheel on the vehicle helps avoid mounting and clearance issues.
Do all 2008 Dodge Trucks Ram 2500 ST sub-models use the same tire size?
Yes. The covered 2008 Dodge Trucks Ram 2500 ST sub-models all use the same 245/70R17 radial tire size, including 4x2 and 4x4 versions in both regular cab and quad cab form. That consistency makes the initial fitment choice much simpler than on trucks with multiple OE-style sizes.
Shared tire size does not automatically mean every truck is still configured the same way today. Wheel swaps, leveling kits, lift kits, or suspension wear can change the practical space around the tire, so it is still smart to verify wheel specs and clearance before replacing a full set.
Choosing the Right Tire
What should I consider when choosing a 245/70R17 tire for a 2008 Dodge Trucks Ram 2500 ST?
Start with the correct 245/70R17 size, radial construction, and 17-inch wheel diameter. On this truck, those basics matter because the Ram 2500 ST is a heavy-duty platform, so the replacement tire should also be evaluated for rim-width compatibility, load capacity, and the kind of road or mixed-surface use the truck actually sees.
Appearance and tread character also play a role. A tire such as the BFGoodrich All Terrain T/A KO2 adds an all-terrain look and utility-focused personality, while its raised white letter sidewall gives the truck a more assertive visual presentation than a plain blackwall-style sidewall would.
What sidewall styles are available for 2008 Dodge Trucks Ram 2500 ST tires?
The available 245/70R17 option for the 2008 Dodge Trucks Ram 2500 ST uses an RWL sidewall, meaning raised white letters. That gives the tire a more visible, traditional light-truck appearance than an all-black sidewall and can change the truck's overall look even when the size remains completely correct.
Sidewall style is mostly an appearance decision unless a buyer is trying to match an existing set or preserve a certain period of truck styling. It still makes sense to keep fitment first by confirming size, wheel compatibility, and use case before letting the sidewall treatment decide the purchase.
What brands offer tires for the 2008 Dodge Trucks Ram 2500 ST?
The available product in the 2008 Dodge Trucks Ram 2500 ST's 245/70R17 size is from BFGoodrich. It appears in the All Terrain T/A KO2 line, which keeps the selection focused on a recognized all-terrain radial rather than splitting the buyer across several brands with very different sizing or visual presentations.
With a narrower brand spread, the comparison shifts toward whether that tire's character fits the truck's role. Owners should look at wheel-width compatibility, load support, sidewall style, and how closely the tire's all-terrain personality matches the truck's real mix of highway, work, and occasional off-pavement use.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Dodge Trucks Ram 2500 ST?
For a period-style 2008 Dodge Trucks Ram 2500 ST, the right starting point is the correct 245/70R17 radial size on the proper 17-inch wheel. Since this truck belongs to a modern heavy-duty pickup era rather than a bias-ply restoration era, keeping the original-style sizing approach matters more than chasing an older construction type.
Appearance can then be shaped through tread character and sidewall presentation. An all-terrain radial with raised white letters gives the truck a strong late-2000s light-truck look, but buyers seeking exact historical authenticity should also compare against original sales literature, window sticker information, or marque-specific references.
How does tire construction affect the appearance of a restored 2008 Dodge Trucks Ram 2500 ST?
Tire construction affects both the look and the stance of a restored 2008 Dodge Trucks Ram 2500 ST, but in this case the primary fitment is already radial. That means a restoration-minded owner is usually deciding within the correct modern construction family rather than choosing between a vintage bias-ply look and a modern radial profile.
Visual differences are more likely to come from tread style, sidewall treatment, and how the tire fills the wheel opening. Keeping the truck in the proper 245/70R17 size on a 17-inch wheel preserves the intended overall presentation far more reliably than experimenting with a different diameter or profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Dodge Trucks Ram 2500 ST?
Yes. Even though the 2008 Dodge Trucks Ram 2500 ST uses a straightforward 245/70R17 radial fitment, modifications can still change what works on the truck. Aftermarket wheels, altered wheel offset, leveling kits, lifts, worn suspension parts, or body changes can all affect clearance around the tire.
A truck that has been modified may still carry the same nominal tire size but behave differently at full steering lock or under load. Checking wheel width, actual wheel diameter, suspension travel, and space at the fender and inner wheelhouse helps prevent rubbing or mismatch before mounting replacement tires.
What should I inspect before driving a 2008 Dodge Trucks Ram 2500 ST on new tires?
Inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering before driving a 2008 Dodge Trucks Ram 2500 ST on new tires. It also makes sense to confirm air pressure, verify that the tires were mounted on the correct 17-inch wheels, and look for any immediate clearance concerns.
A heavy-duty truck places meaningful demands on its tires, so the condition of the rest of the chassis matters. Uneven wear patterns, loose front-end components, or alignment issues can shorten tire life quickly, and any signs of vibration, pulling, or rubbing should be addressed before normal driving resumes.
How should 245/70R17 tires on a 2008 Dodge Trucks Ram 2500 ST be maintained?
245/70R17 tires on a 2008 Dodge Trucks Ram 2500 ST should be maintained with regular pressure checks, routine visual inspections, and attention to tread wear across the full width of the tire. Owners should also watch for cuts, punctures, bulges, sidewall damage, and signs of irregular wear that may point to alignment or suspension issues.
Because this is a three-quarter-ton truck, tire maintenance should match actual use rather than casual passenger-car habits. Long idle periods, heavy hauling, and mixed on-road or off-road use can all change wear patterns, so periodic rotation and checking for slow air loss help preserve both road manners and service life.
