Apps fantastic works great especially when trying to calculate what will fit, however if you’re running tires larger then 33” the screen runs out of room and the edges of the tire vanish which makes it hard when you’re looking at a few different tires. Also if there was an option to enter the measurements of the knuckle or brake caliper clearance would be fantastic!

What a great app, and it’s free! Used it to see how large a tire I could fit on my Miata MX-5. Being able to change the offset and have a comparison between two tires is awesome. It has helped me calculate just how large I can go.The only change I would make is on the speed side. Show me what the speedometer shows and what your actual speed is. I can do this now in a round about fashion.

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. 🤓

I have used this quite a bit for quick reference . The only thing I wished is that it had one more speed limit comparison, as most highway speeds are above 60 mph now a days
