2021 Aries. Pain in the ass

Wish I could just plug it into the OBD connector instead of the green box. It would be a lot easier. You have to remove the dashboard to get to the green box.

Pros
  • Stylish and modern design
Cons
  • dim

Mandatory for large wheels

A must for those changing tire sizes to ensure your speedometer reads correctly. However, it's important to remember that once you use it on a vehicle, it's "married to your vehicle." This means it cannot be used on other vehicles.

Pros
  • Ideal for outdoor activities
Cons
  • Having trouble

Works great for sensors

Did what it said it will do. I used it on my classic 2019 Ram 1500 on which I mounted 35" tires. Measured the tire on the vehicle and entered the data into the programmer. On the first try, the speedometer deviated slightly. On the programmer, reduced the size by 0.5" and after that everything was fine. It was a very simple process.

Pros
  • Lots of positive emotions
Cons
  • Everything is fine

My speedometer is correct now but it was a pain to get there!

If I had to do it again I would just pay the dealer to change the tire size. I went up 1" from the factory, but set the programmer 1" smaller than the factory, which is 2" off the advertised tire size. You must measure the actual tire size and subtract 0.5 to 1 inch for it to display correctly.

Pros
  • Good product for the price
Cons
  • Some cons

Ease of use: Electric

This product was very easy to use, just plug it in and follow the instructions. I have a RAM 5.7L 2019 with 35x12.5x20. At highway speeds I was 4-5 mph faster than my speedometer showed using Waze and the speedometer app. I googled my tire sizes which came up with 34.53 inches but using a tape measure shows around 34 inches. I first tried using 34.5 during reprogramming but the speedometer showed about 2-3mph slower than what the apps showed so I went with 34 inches and the apps seem almostโ€ฆ

Pros
  • Consistent test results
Cons
  • Newer model could have been chosen

Is it worth? for speedos

I bought it on my Ram 1500 5.7l 2019. First of all, the installation instructions said update first, that was the first problem. When you go to a website and click refresh, malicious Bytes and Windows Defender block the download. They think it is a teal backdoor Trojan, which is scary to say the least. I had to turn it off for both installing on the PC and updating the tool. I emailed rude country and got no response. I took a chance and built and mounted 33.5" tires to 285/60/20 specs. Myโ€ฆ

Pros
  • a nice thing
Cons
  • I don't remember but there was something

A MUST FOR FITTING TIRES!

Great product. I put new tires on my Ram 1500. Were 275/60R20. Went for 65s. They knocked out my truck. Went from an average of 18mpg to 14 and drops. The truck will no longer go into eco mode on the freeway unless I'm driving at 55-60 mph. Got this little device, followed the simple instructions. It is important to know that when connecting, it will ask for the tire size in inches. So google the tire size in inches beforehand. Mine was 34.3 and the car gave me a choice of 34.25 or 34.5. Iโ€ฆ

Pros
  • Best
Cons
  • Ugly packaging
