I found this free online program after breaking my head about what tire size I needed when lifting my ex. i read a lot of threads but most tell you what they are running. Well, each driver has a different need for what they want. check this Site. out

If your thinking of adding larger tires or lift kit, It lets you see exactly what your Excursion will look like with different tire sizes.

You can change the color to match your Ex or you can see what it would look like in another color
You can customize the high of your truck in real time.
You can test all tire sizes on your truck and add real brand rims in real time.
Helps with tire dimensions and calculations.

Here is the Site. It's free!!

 

I have thought about something like this for YEARS! I just dont possess the programming knowledge. Way cool.

I envisioned it to be used on sites like Riffraff that specialize in a specific vehicle(s) and then you can add ANYTHING they sell to see what it would look like.

 

Very nice! Thanks.

 

I found it very usefull in the planing process. Hope it helps..

 

There are several sites out there that do this. But this is the most accurate by far. I know exactly what tire I need and what I can get away with at different height levels. I just wish it had a way to level off the heights on frontend and rearend separately. But very useful when taking that next step.

 

Hope this helps.

 

Wanted to bump this up for those looking to change tires. Very useful tool.
