2004 Silverado SS

[Rex]

I have a 04 SS Silverado so I have the U7193. The truck came with 20" wheels
and I put 24" wheels on. There is about a good inch or so hight diff between the two tires. I went to change the tire size and it kept on telling me that it was
not a good tire size. Do I not have that op?? Also what do I have to do to get a tune made for my truck.. I have some aftermarket ops on it???

If you are entering the metric tire size from the sidewall, it should be good.
What size are the tires?

If you need a tune we have a nationwide network of CMR dealers that can do a tune for you right on their dyno.
Use the where to buy tab above to find a dealer in your area.

The Tires are 305/35/24......

I cannot see why the Predator would not allow you to enter this size.
If it will not work, try entering the height of 32.5" or enter 305/44/22, this will register as the same size.

Thanks
