Ok, so in the city I have dropped off from around 15.5(min)-17 to 14.5. Not good.
I recently added a 3 inch lift (can't see how that would matter), and new Goodyear Wrangler Silent Armors 265/75R16 123's . I had the same size but worn down BFG's before. Except I don't think the load factor was 123. But I'm not sure. I am running them at 35 psi as this is what Discount Tire (American Tire if you are in CA), recommends.
Also, I have been noticing a squeaking noise that happens after I have been on the brakes, but not while I am on them. It emanates from the left front wheel. It was happening before the new lift and tires. When I had the truck up for the lift, I could spin that wheel and hear some sort of friction. Like an idiot I did not go to the other side to see if the same thing happened. Has anyone else heard this noise when you have the truck up and on the jack, or after braking?
So anyway, could the tires be the culprit? Is it possible that the noise and possible friction could be aiding this, or not related? Theories? I would appreciate anything.
