Concept
To help us move forward, we brainstormed appropriate solutions based on the opportunities we identified during the consumer journey. In addition to categorizing our ideas, we went through multiple rounds of discussions to find what we thought were the key tasks.

Prototype V.1
• 🧮 Tire Life Calculator
The tire life calculator is the main requirement of the customer. The calculation of the tire life is done by using the MAXXIS’s database, with the current tire mileage entered by the customer, combined with the tire's date of manufacture.
• 📡 Tread Scanner
Use the LiDAR lens on the phone to accurately scan the tread depth of the tires before a long trip. Once the scan is complete, the app will display the exact tread depth and advise customers when to change tires.
• 📝 Personalized Advisor
By inputting personal driving information, such as car models and driving areas, MAXXIS can provide customers with more professional advice through its database.
03 EVALUATION
We tested Prototype V.1 with five users and, based on this data, finalized the design using problems from the testing and feedback from users. Listed below are the problems we found and how we analyzed them and redesigned them.
User Testing
On-site Testing
• Insight 3 : 🤯 Manual data entry is too time-consuming and frustrating for users.
Change :
Information Architecture & Logic
In our tests, we found that users are very resistant to manual data entry, and almost every user feedback that this will reduce the frequency of their use of the product, so we switched to GPS positioning to provide user information and allow them to actively filter whether to upload data, such a process can greatly reduce the burden of users in the use of the product.
When the application detects that the user is moving at the vehicle's speed, it will record the time on the trip page, and the user can select which data belongs to the mileage they have passed while driving and upload it to the tire life progress bar on the home page.
• Insight 2 : 😰 Can't find the key information.
Change :
Highlight key messages as well as features
1. To the user, it's very meaningless to give a date indication, they are more sensitive to the number of the depth of the tread, so we changed the depth of the tread to a more visible place.
2. Features located in the scanning screen are very difficult for users to recognize, so we gave the flashlight and the scanned part of the background to highlight the icon so that users won't be confused by the complex screen.
• Insight 1 : 😵💫 Overly complex, users are overwhelmed.
Change :
Adjusting the functional hierarchy of a page
1. Users are easily distracted by the cars on the screen and become accustomed to clicking on them when they are in use, resulting in many errors. So we reduced the proportion of cars on the page to allow users to quickly locate the information they need.
2. Users often need to click on the front and rear wheel switches to refresh their memories, which is very unintuitive for them, so we display all tires directly on the homepage so that users can see them at a glance without having to do much.
3. Through user feedback, we realized that the features that were originally in the main feature list were not used as much as they should be, so we moved the features that were used more often to the list.
Change :
Provide enough motivation to the user
1. Users don't have enough knowledge about the product, so we directly categorize the product on the search list to let users know the main features of the product and make it easy for them to make a purchase.
2. During user testing, users reported that there were no other ratings and reviews provided to users, leaving them without a reliable basis for browsing the product. Therefore, we imported the existing data from the official website to provide users with a reference.
In the end, we presented the final version to the stakeholders and they were very satisfied with the results, and we recommended the proposal to their marketing team to help transform the brand by combining existing products with digitization.

Tire Life Calculator
Customers can get expert advice on whether or not to replace their tires with LifeSaver, which combines tire mileage and year of manufacture to assess tire life. By detecting the user's daily driving path, it automatically updates the mileage and age of the tires so the user knows when it's time to replace them.
Tread Scanner
When customers need to travel long distances, Lifesaver can scan the tire tread depth through the LiDAR lens on the phone and use the results as suggestions for customers to change tires. In addition to this, it also provides a guide to tire depth and safety.
DESIGN SOLUTION
Design an application to assess tire life using MAXXIS’s database to provide customers with services before and after tire purchase.
Personalized Settings
It meets the needs of different users through personalization and multiple settings. When replacing tires, simply scan the invoice or serial number of the tire for quick uploading, and it also offers the ability to add other vehicles, allowing users to manage the life of tires on all their vehicles at the same time.
