I have one new (March 2016 is replacement date) tire on my motorhome that replaced one with a small cut in it.
Went to Rv dealer today to get oil change. They checked tires and said one of my inside duallies was cracked along the rim so I needed a new tire. Tire dealer said I needed to replace three other tires and maybe all older tires--5 in all because some were beginning to crack. Because I am short of $$$ after spending a lot of repairs and two new crowns on my teeth recently ($3,000 worth) so I said to just order 3. Will get two more later this year when I can afford it.
Now the tire guy said best tires should go on rear dual tires. I said I wanted two new tires on front. They argued against that vehemently.
So, am I nuts???
