How to Adjust Speedometer for Bigger Tires Ram 1500

If you have ever put bigger tires on your Ram 1500, you may have noticed that your speedometer is now reading incorrectly. The reason for this is because the larger tires cause the truck to travel a greater distance per revolution than the smaller ones did. This means that when traveling at the same speed, the larger tires are actually covering more ground and going faster.

Fortunately, there is an easy way to adjust your speedometer so that it is accurate again.

  • Park your Ram 1500 on a level surface and turn off the engine
  • Locate the speedometer cable where it enters the vehicle on the driver’s side near the firewall
  • Unscrew the retaining clip that secures the cable to the vehicle with a Phillips screwdriver
  • Pull the speedometer cable out of its housing enough so that you can access the end of it
  • Place one end of a pair of needle-nose pliers onto the small, square-shaped tab at the end of the speedometer cable, and pull gently until it comes off completely
  • Insertthe new square tab that comes with your bigger tires’speedometer recalibration kit into place on top of Needle-nose pliers,and press firmly until it snaps into place

2022 Ram 1500 Speedometer Calibration

Are you looking to calibrate your 2022 Ram 1500 speedometer? If so, you’ve come to the right place! In this blog post, we’ll walk you through the steps needed to ensure your speedometer is accurate.

First, let’s talk about why calibration is important. Your speedometer is what lets you know how fast you’re going, so it’s important that it’s accurate. If it’s not, you could end up speeding and getting a ticket, or worse.

Speedometers can become inaccurate over time due to wear and tear, so it’s important to calibrate them regularly. Now that we know why calibration is important, let’s get into the steps needed to do it. First, you’ll need to find a flat stretch of road where you can accurately measure your speed.

Once you have that, start driving at a consistent speed and use a stopwatch or your phone to time yourself for one mile. Compare that time with the mileage reading on your odometer – if they match up, then your speedometer is accurate and doesn’t need any adjustment. However, if there is a discrepancy between the two readings, you’ll need to adjust your speedometer accordingly.

To do this, simply multiply the difference between the two readings by 100 (this will give you percent error). For example: if your odometer reads 20 miles after one hour of driving but your stopwatch says it took 50 minutes to complete those 20 miles – thenyou would multiply .5 (the difference in time) by 100 which would giveyou 50%. This means thatyour speedometererrorsby 50% and needsadjustment.

There are a few different ways that you can adjust yourspeedometer;which methodyou choose will depend on whetheryourvehiclehas an electronic or mechanicalspeedometerrating system: Mechanical Speedometers:If yourspeedometerrating systemis entirelymechanical(i.e., no electronics are involved),thenyoushould be ableto make adjustmentsby looseningor tighteningthe cablethat connectsit toyourtransmission .

How Do You Recalibrate Your Speedometer for Larger Tires?

If you have larger tires on your vehicle, you will need to recalibrate your speedometer so that it is accurate. This can be done by using a GPS speedometer app or by visiting a local shop that specializes in vehicle calibration. Most newer vehicles have what is called a tire pressure monitoring system, or TPMS, which can be used to help with this process.

The TPMS will sense when the tires are low on air and alert the driver. It can also be used to help determine the correct air pressure for the new tires. Once you have the new air pressure for the tires, you will need to adjust the settings in the speedometer.

This can usually be done through the vehicle’s infotainment system. Look for a menu option that says something like “vehicle settings” or “tire pressure.” From there, you should be able to enter in the new information for your tires.

How Do You Change the Tire Size on a Dodge Ram 1500?

If you need to change the tire size on your Dodge Ram 1500, it’s important to know a few things first. Tire sizes can be expressed in many different ways, and each way tells you something different about the tire. The most common way to express tire size is with the width, height, and rim size, like this: P215/75R15.

The first number in this example (215) is the width of the tire in millimeters. The second number (75) is the height of the sidewall as a percentage of the width. In other words, if the sidewall was exactly 75% as tall as it was wide, it would be 150 millimeters tall (75% of 215mm).

However, most tires are not exactly 75% as tall as they are wide – that’s just an average. The last number (15) is the diameter of the wheel that this tire will fit on, in inches. Now that we know how to read a tire size designation, let’s talk about changing tire sizes on your Ram 1500.

There are a few reasons why you might want or need to do this: perhaps you’re going off-roading and need some bigger tires for more ground clearance; maybe you want to improve your fuel economy by switching to lower-rolling-resistance tires; or maybe you just want a different look for your truck. Whatever your reason may be, there are a few things you need to keep in mind when changing your Ram’s tire size. First and foremost among these is speedometer calibration.

If you don’t calibrate your speedometer after changing tire sizes, your speedometer will give false readings – meaning you could end up speeding without realizing it! This could lead to costly tickets or even accidents. Fortunately, there are many ways to calibrate your speedometer after changing tire sizes; consult your owner’s manual or an automotive technician for more information specific to your vehicle model year and engine type.

Another thing to consider when changing tire sizes is load capacity rating. This is basically how much weight each individual tire can support safely – both while driving and while parked/stopped – and is expressed in pounds (or kilograms). It’s important not exceed any one single tire’s load capacity rating; if you do so regularly, premature tread wear and blowouts could result.

Can I Put Bigger Tires on My Ram 1500?

Yes, you can put bigger tires on your Ram 1500 as long as they are the same diameter as the factory tires. If you go with a larger diameter tire, you will need to make sure that the new tires fit inside the fenders and do not rub when turning. You may also need to adjust the air pressure in the shocks to accommodate for the larger tires.

How Do You Change the Tire Size on a 2021 Ram 1500?

The 2021 Ram 1500 comes with a few different tire size options from the factory. If you’re looking to change the tire size on your Ram 1500, there are a few things you’ll need to take into account. First, you’ll need to know what size tires your Ram 1500 came with from the factory.

You can find this information in your owner’s manual or on the door placard located on the driver’s side doorjamb. Once you have this information, you can start shopping for new tires. When choosing new tires, it’s important to make sure they are compatible with your Ram 1500’s suspension and drivetrain.

You’ll also want to make sure the new tires are of a similar size and load rating as the original equipment tires. Failure to do so could result in decreased performance and handling, as well as increased wear and tear on your truck’s components. Once you’ve found the right tires for your 2021 Ram 1500, changing them is relatively straightforward.

If you’re comfortable working with tools and lifting heavy objects, you should be able to complete the job in about an hour or so.

Speedometer Calibration – Adjust for Bigger Tires – Accurate Shifting & Fuel Economy

Conclusion

If you have bigger tires on your Ram 1500, then you will need to adjust the speedometer so that it is accurate. There are a few different ways that you can do this, but the easiest way is to use a GPS speedometer calibration device. You can find these devices online or at most auto parts stores.

Once you have one of these devices, all you need to do is drive your truck at a constant speed for a few miles and then enter the new tire size into the device. The device will then recalibrate the speedometer for you.
