Dodge Trucks Ram 1500 ST Tires

Dodge Trucks Ram 1500 ST uses two tire sizes across the 2005 to 2010 range: 245/70R17 and 265/70R17. The 245/70R17 size appears on 2005 through 2008 trucks and uses a 17-inch rim, while 265/70R17 appears from 2005 through 2010 and also uses a 17-inch rim. Among the listed products, the 245 size fits 6.5 to 8.0 inch rim widths, and the 265 size fits 7.0 to 9.0 inch rim widths.

That means the main fitment question is not wheel diameter, since both sizes use 17-inch rims, but whether your specific Ram 1500 ST was equipped for the narrower or wider tire. Check the existing sidewall marking, confirm the wheel width, and compare the truck's year with the size range before choosing. For 2009 and 2010, the fitment is simpler because only 265/70R17 is listed.

On Dodge Trucks Ram 1500 ST, 245/70R17 is a metric radial size. The 245 is the section width in millimeters, 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, R identifies radial construction, and 17 is the required rim diameter in inches. The listed product in this size also fits wheels measuring 6.5 to 8.0 inches wide.

Reading the size correctly helps you avoid choosing a tire that is close in diameter but wrong in width or wheel fit. On an early Ram 1500 ST, this size points to the narrower of the two listed fitments, so it should be matched to the truck's actual wheel and current tire specification. It is a modern size format, which makes sidewall verification straightforward.

A 2005 Dodge Trucks Ram 1500 ST can use either 245/70R17 or 265/70R17, and both sizes share the same 17-inch rim diameter. Because there is no rim diameter split and both listed products are radial, the difference points to a configuration split within the model range rather than a change in wheel size or tire construction. The narrower 245 fitment and the wider 265 fitment were both used in the early years.

That means year alone is not enough to choose correctly for 2005 through 2008 trucks. The practical way forward is to inspect the size already on the truck, confirm wheel width, and compare overall setup before replacing tires. If the truck has changed hands or wheels have been swapped over time, do not assume the present tire size matches the original configuration.

Dodge Trucks Ram 1500 ST uses a 17-inch rim diameter for both listed tire sizes. The 245/70R17 fitment and the 265/70R17 fitment are both built for 17-inch wheels, so there is no wheel diameter change across the 2005 to 2010 span covered here. The main variation is tire width and associated approved rim width range, not the wheel diameter itself.

That simplifies one part of the search, but it does not make every 17-inch tire interchangeable. You still need the correct section width, aspect ratio, and suitable wheel width to keep the fitment consistent with the truck's intended setup. Verifying the wheel stamp or existing tire marking is the quickest way to confirm the correct 17-inch specification.

A 2007 Dodge Trucks Ram 1500 ST can use either 245/70R17 or 265/70R17, so the correct choice depends on the specific configuration. Both sizes use a 17-inch rim, but the listed products differ in approved rim width ranges: 6.5 to 8.0 inches for 245/70R17 and 7.0 to 9.0 inches for 265/70R17. The sidewall size on the truck and the wheel width are the two most useful checks.

Start by reading the complete size code on the existing tire, then compare that with the wheel's actual width rather than assuming every ST was equipped the same way. That matters especially on older trucks that may have had wheel or tire changes during service life. Matching both the size and the wheel width range will keep the replacement consistent with the truck's setup.

The listed Dodge Trucks Ram 1500 ST products use RWL sidewalls. RWL stands for raised white letters, a style commonly associated with all-terrain and light truck applications. Every product shown for both listed sizes shares that same sidewall treatment.

If you want the truck to keep the period look reflected by these available products, RWL is the sidewall style represented here. Appearance still depends on how the tire is mounted and whether the white-letter side is turned outward or inward, but the core style remains the same. Buyers focused on a consistent visual match should compare all four tires before installation.

None of the listed Dodge Trucks Ram 1500 ST products are identified as made to order. The available 245/70R17 and 265/70R17 options are presented as standard radial product listings rather than special production runs. That means there is no separate made-to-order consideration affecting the listed fitments here.

For the buyer, the real decision points are size, wheel width range, sidewall style, and load rating rather than build status. On this page, a 265/70R17 buyer should also compare the two available versions because they carry different load capacities and inflation figures. Choosing by vehicle use matters as much as choosing by size.

A stored Dodge Trucks Ram 1500 ST should be kept in a cool, dry, dark environment with the tires protected from sunlight, ozone, and standing moisture. Clean concrete is acceptable, but keeping the truck away from welders, electric motors, or equipment that generates ozone helps preserve the rubber. If the truck will sit for long periods, maintain proper inflation and move it occasionally to reduce flat spotting.

Because Ram 1500 ST uses modern radial truck tires, storage habits directly affect ride quality when the truck returns to the road. Long stationary periods under load can create temporary or lasting shape distortion, especially on heavier pickups. If the truck is part of a collection, periodic movement and pressure checks are simple steps that help extend tire life.

Tires on a Dodge Trucks Ram 1500 ST should be inspected before regular driving and again any time the truck has been stored for an extended period. Look for pressure loss, sidewall cracking, cuts, punctures, uneven wear, and any sign of impact damage. On the 265/70R17 size in particular, also confirm that the tire's load rating still matches how the truck is being used.

Frequent inspection matters because a collector or lightly used truck often ages its tires by time as much as by mileage. A tread pattern can still look serviceable while the casing has begun to harden or deteriorate. Making inspection part of every pre-drive routine is one of the easiest ways to catch issues before they become a highway problem.

Tires on a Dodge Trucks Ram 1500 ST should be replaced when age, cracking, impact damage, bulges, repeated air loss, or severe hardening appear, even if tread depth still looks usable. Collector and low-mile trucks often reach that point by calendar age rather than wear. Any tire that shows structural distress or has an uncertain service history deserves close evaluation before continued road use.

That rule matters on a half-ton pickup because its tire loads can vary widely between light cruising and actual work use. A tire that looks acceptable parked in the garage may not respond safely once heat, speed, and load build on the road. If the truck has sat for years, replacement should be considered part of recommissioning rather than a cosmetic choice.

The listed Dodge Trucks Ram 1500 ST products are modern radial light-truck tires, so they are fundamentally suited to public-road use when the correct size, load rating, and inflation are matched to the truck. The 245/70R17 listing shows a 3,000-pound maximum load at 80 psi, while the two 265/70R17 listings differ at 2,470 pounds at 50 psi and 3,195 pounds at 80 psi. Safety depends on selecting the version that matches how the truck is actually used.

A lightly driven collector truck and a truck that still carries cargo place different demands on the tire, even when the nominal size is the same. That is why the load specification matters as much as the sidewall code. Road use is reasonable with the right fitment, but the truck should always be evaluated as a complete system, including suspension, brakes, and wheel condition.

Before driving a Dodge Trucks Ram 1500 ST, check tire pressure, visible condition, tread wear pattern, and sidewall size to make sure all four tires match the intended setup. Confirm that the wheel width is appropriate for the tire size in use and inspect for cracking, punctures, bulges, or signs of previous impact. Lug torque, brake function, and general chassis condition also deserve attention on a truck that has been parked.

Those checks are especially important on early 2005 through 2008 trucks because both 245/70R17 and 265/70R17 fitments appear in the range. If one axle has been changed to a different size over time, handling and load balance can be affected. A short inspection before each drive is a practical safeguard, particularly for vehicles used intermittently.

Appropriate speed for a Dodge Trucks Ram 1500 ST depends on the exact tire fitted, its condition, and the service load rather than on the model name alone. The listed tires are modern radial products with speed symbols shown in their size descriptions, but real-world safe speed must still reflect inflation, load, age, and overall mechanical condition. A truck with aging tires or uncertain history should always be driven more conservatively than a freshly sorted example.

For a collector-owned Ram 1500 ST, the sensible approach is to build speed gradually only after confirming pressures, balancing, alignment, and general roadworthiness. Highway capability may exist, but it should never be assumed from size code alone. If the truck still sees utility duty, keep tire temperature, payload, and sustained-speed use in mind because those factors can change the safety margin quickly.
