Hankook tires 20,000 miles. Car shakes, tires choppy and very loud on highway. Dealer has rotated every 3,000 miles and 2011 Ford Focus SE is aligned properly. Worse tires in the world and no satisification from dealer, the Ford co. Or tire company. They are waiting for injuries just like when they put firestorm tires on tree vehicles.

Letter from senator grassley on behalf of constituent regarding his recent experience with his 2011 Ford Focus and his concern that the tires are defective by design; please reply to the attention of sherry kuntz. The consumer stated at 42,000 miles the left tire began wobbling. It was discovered, the tire was out of round. The mechanic rotated the tires and balanced them. The consumer drove the vehicle beyond 43,000 and both front tires began wobbling in the same fashion, but worse. The mechanic noted the tires were bursting radial steel reinforcing wires and going out of round, although the tires had a lot of tread left. The consumer replaced the hankook tires, with Michelin tires.

Ford Focus tires 2011 Ford Focus problems with tires/suspension and warranties purchased 2011 Ford Focus new 20 months ago (with kumho tires, evidently installed at factory) and it has had regular dealer(s) maintenance. Took to purchasing dealer - (luther) North country, coon rapids mn for regular maintenance on November 16, 2012 with 35,366 miles. Was told that tires were 2/32 showing cord (several 1" by 3" spots), 2/32, 4-6/32, and 4-6/32; and dealer recommended 4 new tires (tiger paw) costing $561.95. I asked and was told there was no price reduction from either Ford or kumho warranty. Note that Ford tire warranty guide booklet states 30% for 24K 36K miles; kumho (web) states 60K mileage coverage and 40% for 36K. Incidentally as a conservatively driving mechanical engineer, both my new Sable and Ranger met/exceeded tire mileage coverages. I have been happy with North country, but have lost confidence with Focus and kumho tire company; just got new tires from a local, well-regarded, tire shop; and think Ford/kumho should reimburse me at least $180 (30% of the new tires cost). Note: I hadn't imagined 60K miles tires going through the cords at 36K miles. We recently returned from a 4500 mile mainly interstate trip. If it had been much longer, a tire might well have blown.on the interstate.

The car has poor steering, poor suspension control over bumps, an acknowledged but unrepaired transmission mount, severe alignment issue, tires are feathered and cupped per dealer and dealer is not willing to fix it. The care is unsafe to drive but the dealer states if we do not purchase new tires, pay for an alignment that they will not fix the faulty transmission mount. It has been at 3 Ford dealers in the past 3 weeks. I said nothing is wrong (thomas Ford in beverly MA), next fixed a bearing and 2 suspension parts and said it is fixed (it was not) (danvers motor company, danvers MA) and finally the selling dealer said the alignment, tires and transmission mount are faulty (jack madden Ford, norwood, MA). This care is unsafe and is under bumper to bumper warranty.
