I am new to RV world and just purchased a 2005 Monaco Dynasty that needed new tires 295/80R/22.5 Hard to find. I priced local companies and found Firestones at $700 vs most shops at $900. I didn't think to check manufacture date and now see that dates are from 2016 and 2017. I called tire company and they said I shouldn't be concerned. Should I insist on 2019 manufacture date? Any comments are greatly appreciated.
