Clas C and tires

I put a new set of goodyear load rated truck tires on mine last summer, worked well so far even with a bit of snow. They're the same tires as on my E350 which have held up well except the rv tires are one size smaller. Go figure since the rv is and e450. I put a set of tires from costco on my volvo when I blew one out while away from home. They were cheep and in rage of my limited mini-spare. AWD need to have the same tires on all four wheel so I had to replace them all (needed to anyways) Problem is, those tires suck. They are noisy, poorly track ruts in the road, squeal when going around corners and don't have the traction that the previous set did. Can't wait until they wear out so I can get some good ones.
Tires are the last place you should be cutting corners. I've blown 4 TT tires before the thing finally pulled a major rollover in the middle of the freeway on a wet slippery road. Not pulling a big trailer anymore.
