Problems with 2010 Nissan Versa TIRES

I have ordered a pair of tires from discount tire direct and after i put them on the car, i thought they are ok, so i ordered another pair. few months later one of the tires developed un-round shape and it was torn from the inside. i have contacted discount tire direct, and they forced me to pay another $14, and i returned the bad one and they sent me another one same make and model. this week i have the same problem again. one of the tires developed that un-round shape again. both incidents happened on our family car where my little kids are inside the car. thats unacceptable; if any of these deformations would have caused the tire to explode, that would have caused unacceptable harm to my family. this product threatens the well being of my family. at this time i no longer accept this product at all and i demand a full refund for all the money i have paid so far. i have all receipts, photos for the first tire, photos for the second tire, and all 4 tires. note: the tires writen on them milestar ms932 88h nss-01-12f0

My nissan started leaking air out of the tires....all 4 of them. my son-in-law filled them up to the correct pressure and in a day or two they would be down 4,5, or sometimes 8 lbs. this went on for months until i took it back to the dealership. they said there were no recalls on it. (i asked). they did plug one tire because it had a nail in it, but the other three they said "were just fine". they added pressure to the tires, i paid them and away i went. two days later when i got in the car, the tire pressure light was on again. took it back down to my- son-in-law, he looked at it and the pressure was down 6 lbs. in each tire. went out and bought 4 new tires two days ago. my friend who has a versa bought new tires, but it didn't solve her (same) problem. holding my breath and hoping mine will be ok. why didn't the dealer know of the defect in the tire pressure valve,or were they playing stupid because i was a woman? *tr

The tpms (tire pressure monitoring system) light refuses to go off. the tire pressure is correct per manufacturer's specifications and it has been checked monthly. when the outdoor temperature reaches 80 degrees f., the light shuts off. living in new england, the light is on most of the time. ironically, 3 months into car ownership, we had a flat tire and the light did not come on. the car currently has 14,500 miles on it. *tr

My 2010 nissan versa, with less than 10,000 miles on it, has steel belts popping out the sidewalls of the continental contipro contact p195/55 r16 tires. both front tires have belts popping out. the dealer (empire nissan) has not offered an acceptable solution. the tires are supposedly 60,000 mile tires, but the dealer, in conjunction with the manufacturer, is only offering 25% off list price to replace with another set of continental (crap) tires. there has not yet been an accident, but i am uncertain of how dangerous this condition is. i just noticed the problem 4 days ago. i have photos. *tr
