Had the chance to preview an RV (not a Newell) with a family member looking to purchase.  The front tires happened to be smaller but the same manufacture as what we have on our Newell, albeit, made 30 weeks apart with a date code 1816 in the same year. The history of the previewed RV....stored outside, no wheel covers and used several time`s a year.   Our coach's history, that we acquired at the end of 2018 with the front tires date code of 4816.....the PO stored it outside 2017 & 2018 with no covers.  Once we owned the coach, we use it several times a year, stored it out side 2019 & 2020 with no covers then moved it inside late 2020 and I check tire pressures at least monthly and service accordingly.  Also I apply "303 Aerospace Protectant" to the tires monthly.  Take a look at these images of the previewed coach's tires....
       
And now our tires.....
       
Having said all this in order to get to my point of this post.  The difference, I believe, is the monthly application of 303 and servicing tires.  We are about to replace our front tires on the coach with a date code of 4816 with virtually no weather checking on the tires.  Needless to say the new tires will get the same treatment.
