opinion on wheelbase and tire size??

[yukon635]

I am building a rock racer to beat on and just have fun with so I am not worrying about specs right now. I am just looking for some inputs on whether you like the 2.2 or 1.9 look and at what wheelbase.

or any other suggestions you have. I was thinking the 2.2 at 12", 12.5, or 13" to give it a low profile. by the way, if i go 2.2 i will be using the rock crushers

or the 1.9 at 11" with rock crushers

try 1.9 with a 10 in wb or a 9 should equal about 100" or 90" in 1:1
