I Had Toyo's on mine but they wear a little too quickly for me, 10k fronts were still going strong tho' at 15k.
I changed from Toyo's and are on GT Radials there's not a great deal of difference just that they seem to be wearing better.
As long as you don't mix them, and to be honest that's not 100% true. I've mixed brands due to the fact fronts and rears wear at different rates, and not noticed any difference. I think you'll find that all the issues are related to the 16" wheel sizes and the TF's in particular. Make sure that they are XL Rated for Load, you'll need the extra stiff side wall. Also if you are having difficulty getting the 185's for the front try 195x50x15 there's usually more choice to choose from.
