Excellent App for Tire shop!

This app is amazing !!! Helps a lot with explaining customers on tire sizes and how it will effect their braking and suspension when purchasing new wheels and tires specially if they aren’t OEM sizes!

Excellent

Works great. I wanted new wheels for my truck, but wanted them to be about 5/8”-1” inside the fender flares. The factory wheels were offset so far in, the truck looked like it was wearing roller skates! I didn’t want them sticking out too far, and didn’t like the factory tucked in offset. This helped with find the perfect fit. The wheels ended up being exactly where I wanted them! Thank you!
