Well the car is my family members car and it used up tires in about 40 ,000 kms . i am an appentice mechanic and i've seen this problem so many times and fixed this problem many times .... Fords idea on rubber bushings in the rear suspension is to say the least WEAK.....theses bushings in the lower control arms wear out and cause camber and toe adjustments in the rear to go way out burning up tires in the worst way....fixing this problem involves replacing the entire control arm....as the is no replacement bushings available ... Talk about a pain and a hole in the pocket book

In June of 2006 I bought my focus (with new tires). I am now on my 3rd set, needing my 4th. The rear tires wear out so fast, I am a little over 20000 miles on my current tires and the wires are showing. I took it into the shop today to see how much warranty I have left on these tires. The first set I had put on I bought used/good tires, thinking the dealer just lied and the car didn't come with new tires. Within a month I needed new tires. I went to the Ford dealer and they said that I probably got ripped off buying used. They put on new. A few months later my car started to shake and I looked, I needed new tires again. I went back to the shop and they scratched their heads. I got new tires, warranty covered some but I had to pay some also because I do put alot of miles on my car. After putting them on we noticed wear only after a short time. We went in and had tests done on the car to see if it had ever been in an accident, we have had it aligned everytime we got new tires put on. Went to the shop today to see how much I have to pay again. The mechanic didn't even want me driving it off the lot it is so dangerous. One big problem that we have besides the tires wearing out is that when it rains or snows there is no control of the car. The smallest puddle makes the car slide. If I hit the smallest pebble in the road the car jumps. These things happen even when I drive it off the lot with new tires on. This car is so dangerous that I am afraid to drive it with my kids in the car. I cannot afford to put new tires on the car every 6 months.

We bought a 2003 ford four door focus we noticed a shake in the front end at about 12,000 miles. The dealership checked it out found out that the tires had excess wear so Ford replaced two and we bought two @ $200.00 a piece perilli low profile tires. So at about another 10,000 miles we had another front end shake so we took it back to the dealersip they looked at them again and said that we had excess wear on our tires so this time they couldn't say it was our fault and they had to replace the tires again all four. So we had perilli check the tires they had no good answer as to the wear. At about another 15,000 miles we developed another shake so now the dealership put balancers and stablizers on the car the car developed another shake and bad tires AGAIN so now the dealership has my car and everyone is scratching there heads so we don't know now what is going to be done the saga continues!!!!!!!!
