### 5/5 — Выручало меня не рад

*2025-03-29, version 3.10.0*

Лучшее приложение, очень простой интерфейс и без рекламы. За это отдельный респект. Пользуюсь уже несколько лет. Спасибо.

### 5/5 — Это шедевр

*2024-12-16, version 3.9.1*

Не знаю чуваки, чего вы ждете от этого приложения. Я считаю это просто шедевр. Я кучу колес уже прогнал через это приложение. Реально наглядно понятно что да как поменяется относительно сток колес. Или текущий колес. Резину найти подобрать, вылеты. Господи. Никита который это разработал. Чел, просто спасибо тебе большое. Ты очень меня выручил много раз уже!

### 5/5 — Great app

*2024-10-26, version 3.9.1*

I wish the app can let you add the clearance between the tire and fender neigh but great app I love it

### 5/5 — Nice App

*2024-09-04, version 3.9.0*

I really like this App, no pubs no garbage just useful information. Thank you for your work!

### 5/5 — Awesome work, so handy

*2023-05-14, version 3.7.1*

Paid for the app, worth it

### 5/5 — Easily the Best Tire Size App!

*2023-02-02, version 3.7.1*

This is a fantastic app that does exactly what it says it will. I’ve been using it for many years now since it was first released and it never disappoints. 🏆

* It’s free, but you should definitely consider donating to support the developer and quality, purpose-built apps like this. 🍺

* No data-mining or tracking! 🎉

* Particularly great for finding deals on slightly off size tires that are still a perfect fit for you car without looking ridiculous. Also great for if you have a specific goal like increasing tire surface area on the road for better overall grip and that kind of thing. 🤓

### 5/5 — Great App but fix ride height gain

*2022-05-17, version 3.7.1*

Easy to measure, compare & visualize wheel fitment. Couldn’t ask for better. Only criticism is during calculations, it shares two ride height gain calculations. Im assuming one of the other is fender clearance.

### 5/5 — Spot on

*2022-05-12, version 3.7.1*

Really useful app, especially if you are mad about fine stance tuning where every mm counts when it comes to widen your track but not rubbing suspension or fender / arch.

### 5/5 — Maintenance

*2022-04-01, version 3.7.1*

Good app , lot’s of useful information!

### 5/5 — Go to

*2021-12-06, version 3.5.1*

It is my go to app for tire size Fitment thank you !
