Tire Related Problems of the 2006 Hyundai Santa Fe

Tire Bulge problem

Took vehicle to kauffman tires for wheel balancing. They recommended new tires. They put on cooper discoverer h/t 106t tires. Drove the car home, 2hour drive and immediately noticed bad vibration and the tires felt like they were made of stone! went to dealer, had alignment and wheel balance done. They found the fronts to be one ounce out on each side, and possibly vibration remaining was from a defective tire. Went back to tire dealer with finding. Was told that dealer was probably wrong. I questioned the change from p225's to their recommended p235's, was told by tire dealer that it was ok people use different sizes all the time. I insisted on tires of the car manufacturer recommendation. Had to come back a few days later because they didn't have p225's in stock. When I returned I noticed the right front tire had a bulge as big as a basketball on the side from the rim, across the sidewall and almost to the tread. Tire place put on good year long trails p225's and they seem to be ok. Recommend citizens never trust a tire dealer! always use the tire placard for guidance !.
