Tires are the last place to cut corners. I have not read anything good about tires from China and many have had problems with them. I would stay with a well known brand, and verify that they are not made in China.
Remember, if one of the tires blows up you will cause a ton of damage to your MH. Safety first.
For what it's worth: Purchased 6 Samson tires 2 yrs ago for our DP. Dealer said a lot of OTR trucks were using them. Only have approx 6K miles on them, but so far no problems, rides and drives same as the Bridgestones replaced because of age.
