Recommended Replacement Tires
When it's time for new tires on your 2023 Ram 2500, consider options that offer durability, good towing performance, and a comfortable ride. Here are a few popular choices across different price tiers:
- BFGoodrich All-Terrain T/A KO2 (Premium): A highly regarded all-terrain tire known for its exceptional traction in various conditions, long tread life, and robust construction. Excellent for those who frequently drive off-road or in challenging weather. Expect to pay in the upper tier for these.
- Michelin Defender LTX M/S (Premium): An excellent highway-terrain tire that provides a smooth and quiet ride, excellent wet and dry traction, and impressive longevity. Ideal for drivers who spend most of their time on paved roads and prioritize comfort and fuel efficiency. Also in the upper price tier.
- Firestone Transforce HT2 (Mid-Range): A durable highway-terrain tire designed for heavy-duty trucks, offering good all-season traction and a strong load-carrying capacity. A solid choice for towing and hauling without breaking the bank. Mid-range pricing.
- Goodyear Wrangler Workhorse HT (Mid-Range): Engineered for commercial and heavy-duty use, this tire provides reliable all-season traction, long tread life, and good resistance to chips and cuts. Another solid mid-range option for hard-working trucks.
- General Grabber HTS60 (Value/Mid-Range): A good all-season tire that delivers a comfortable ride, dependable traction, and a decent tread life at a more accessible price point. A strong contender if you're looking for value.
When to Inflate to Max Load PSI
For heavy-duty trucks like the Ram 2500, understanding maximum load tire pressure is crucial. The maximum cold inflation pressure listed on the tire's sidewall (e.g., 80 psi) is the pressure required to support the tire's maximum rated load capacity. You should inflate your tires to this maximum pressure when:
- You are towing a heavy trailer: Especially when nearing the truck's maximum towing capacity.
- You are carrying a heavy payload: Such as a loaded bed or a heavy slide-in camper, approaching the truck's Gross Vehicle Weight Rating (GVWR).
- You are consistently operating the vehicle at or near its maximum capacities.
In these scenarios, insufficient tire pressure can lead to excessive heat buildup, premature tire wear, reduced stability, and potential tire failure. Always refer to your truck's door jamb placard for minimum recommended pressures, and adjust upwards for heavy loads up to the maximum pressure listed on the tire sidewall. When unloaded, you can often reduce the rear tire pressure closer to the placard
