Thanks to the help. To make it clear, I bought new set of tires plus spare (5) total. Spare is riding in storage box below. Reason for questions is I am new to RV's, the old ones I had was dated 2005 if I read right, had splits in center of tread, my trailer is a 2006 model.
Read that it is best to keep out of sunlight when not using. Not sure
why it is worst for trailer tires than cars? Also not to put armor all stuff on them as well.
Since I dropped some $$$ on them want to protect my investment. So looking to those who use them or not or make their own for suggestions?
As to different brand names, like everything else out there, more than 1 brand, maybe better quality?
Maybe this helps to understand question.
Thanks
