What Are the Biggest Tires on Stock Ram 1500 4WD? [+How to Install ]

How big is too big? Monster tires on a pickup truck look genuinely extraordinary. But there’s also a need to look at practical realities.  Bigger tires mean higher fuel consumption. A higher center of gravity can also result in tip-overs in an accident. Keeping these factors in mind, let’s look at why it makes sense to have the biggest tires on a Stock Ram 1500 4WD.

Benefits of Installing Bigger Tires on a Ram 1500 4WD

The advantages of having bigger tires include:

More Miles

Can cover more distance with each revolution. Like longer legs, bigger tires can take you further.

Better Grip

Wider low-profile tires offer more grip. More road surface contact = more traction and better control of the truck.

Lifts the Truck

Avoids under-carriage scrapes/impacts. Higher clearance to ride over speed bumps, potholes, and edges.

Softens the Ride

The ride is less bumpy with these tires, as more air cushions with bigger tires absorb uneven road shocks more effectively

Better Reaction

The change is worth it once the truck is on highways. The ride feels smooth. The driver has a high vantage view lets you see further.

While this may not seem much, the extra microseconds of reaction time can make a huge difference in an emergency.

Superb Off-Road

The more significant gain is when driving off-road on dirt tracks. Bigger tires ‘bite’ better as larger contact surfaces grip more.

The higher displacement also reduces damage to the undercarriage.

Are There Downsides to Installing Bigger Tires on a Ram 1500 4WD?

Less Fuel Efficiency

It takes more energy to move bigger – thus heavier – tires.

More Tire Damage

It offers limited wheel space as the turn radius can get reduced, so tires may be damaged by scrapes.

Requires Vehicle Reset

You will need to reset the odometer, speedometer, brakes, and suspension. Adjusting these settings can be tricky as the truck will be moving faster with bigger tires.

Higher Costs

Changing to bigger tires involves extra costs both upfront and in the longer run.

Upsizing can also mean buying larger wheel rims. Further, bigger tires cost more to replace and typically wear out faster.

They push the limit on how to still fit within wheel wells without alterations.

If you want to boost your truck’s appeal to the next level, adding an aggressive yet casual look – this one would be the perfect choice.

  • Feels quiet at high speeds
  • Outstanding tread life
  • Excitingly beautiful tread pattern
  • Extra handling capacity

What We Didn’t Like

  • Not perfect for off-road use

How to Install Tires on a Ram 1500 4WD?

You can DIY install new tires on rims – but it takes a bit of grunt work. The critical factor is to first make sure the tires and rims are the same sizes.

Otherwise, you’ll either have to swap for right-sized tires or get new rims.

Tools needed

  • Screwdriver (s)
  • Prying bar (s)
  • Vise grips (optional)
  • Truck jack & wrench
  • Electric air pump
  • Tire pressure gauge
  • Rags and detergent

Removing the tire

  1. You have to first remove each tire, one at a time. Raise the truck using the jack, loosen the lug nuts with the wrench, then gently pull off the wheel.
  2. Place the wheel flat on the ground to deflate the tire. Unscrew the cap, then gently press the pin within with the screwdriver to release the pressurized air. This can take a while.
  3. Before removing the tire from the rim, apply some detergent around the tire edges (or beads). Wipe clean. Then use the prying bar to push down the tire edge from the wheel rim.
  4. Insert vise grips to keep the tire edges away all around the rim. Alternatively, you can use screwdrivers or extra prying bars.
  5. Now insert a prying bar under the edge and pull it off the wheel rim. Do this every few inches apart till the tire edge is off the wheel rim.
  6. Turn over the wheel and proceed to pry the other tire edge off the rim. Remember that you’re removing the tire, not loosening it. Once the entire edge is pried off, the rim can be lifted off the old tire.

Fitting new tire

Fitting on the new tire is just a reverse process. Before you start, make sure the air pressure valve is fitted correctly.

  1. Place the tire on the wheel and gently pry the edge into the rim well, inch-by-inch.
  2. Once one tire edge is fully fitted onto the rim, turn the wheel over. Repeat with the other tire edge.
  3. When the tire is entirely within the rim well, inflate with the air pump. The tire edges will snap into place.
  4. Use the pressure gauge to ensure the tire is inflated correctly. Then fit back on the truck, tighten the lug nuts with the wrench and release the jack.

What’s next?

This process has to be done for all 4 tires. Since you’ve now gone for what’s the biggest tires for a Stock Ram 1500, you should also replace the spare.

Otherwise, the spare will get old and start cracking. The truck’s drive will be uneven if the defunct spare is used when stuck with a flat tire.

Once all new tires have been installed on the truck, it will be good to visit a workshop for the wheels to be appropriately balanced.

This will ensure a smooth and comfortable drive and reduce tire wear.

Major (FAQs) of  Biggest Tires on Stock Ram 1500 4WD

What is the biggest tire size for my Dodge Ram 1500?

Without any modifications, 35-inch tires fit well on 22-inch rims. Raising the truck’s suspension can use 37-inch tires. Getting any larger will result in a monster-tire truck.

How often should I change tires on my Dodge Ram 1500?

Most tires last around 40,000 – 50,000 miles, typically about 2 years. Use the penny test.

Can you see the wording from the side when a coin has placed the channel between treads? It’s then time to change the tires.

Do tires have expiry dates?

Yes, this is set at 6 years from the manufacturing date. To avoid possible failures, don’t get tires sitting on shelves overlong. It’s best to get tires that are still within 2 years of the manufacturing date.

Should bigger tires have higher pressure?

No. Bigger tires need more air volume to inflate. But the pressure should be what the truck manufacturers recommend.

  • Over-inflated tires reduce the road contact patch area. This affects braking and drive control.
  • Under-inflated tires heat up fast. Sidewalls have to work harder to retain their shape during a drive. When a tire wall is weakened too much, it collapses, and the tire explodes.

Is on-vehicle wheel balancing necessary?

It is highly recommended to reduce tire wear. There will also be less ‘vibrating’ when driving at higher speeds, giving a more comfortable ride.

Why do my tires squeal when driving around corners?

They may be underinflated. If the tire pressure is acceptable, consult a nearby workshop. The squealing could indicate a possible suspension problem.

Conclusion

Always pay attention to the biggest tires on Stock Ram 1500 4WD. They are the only contact between the vehicle and the road.

Remember, size isn’t the only critical point. Choosing the correct type of tire to match your driving habits can often be essential to avoid accidents.

Another good habit is to regularly check tires. Make sure they’re adequately inflated. See if there’s any unusual wear.

Do the same with the spare. Maintenance isn’t just about washing tires, so they look good. You take care of them, and they’ll take care of you.
