I don't think I can run a 235 DR. That is 2 inches shorter and 2 inches narrower than what I have now. I have traction issues as it is. I also have 15x10 wheels so a 235 might be pushing it there as well.
You want a 10 wide wheel with a 235, or 8 inch slick. You will have a bigger contact patch area. If you have traction issues look at your suspension. Just giving you something to look at.
