So far so good. They are a little louder than I thought that they would be on the road and I haven't had a chance to air them down yet and see what they can do but the appearance of them is great.
Have you noticed any major change in MPG? I had them for about a month on my 2012 DCSB and they had to go. I lost like 45 miles on a tank.
It hasn't seemed so. But I also regeared my truck to 4.56 gears from Nitro so I'm not really sure. Before the regear and tires I was only getting 280ish out of a tank. After the regear I'm at about 330ish. So I have no idea.
