Tire sizes too small

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!

Great app to figure out what fits.

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.

Quick reference

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
