Tire Information — Important Buyer Note
The current tires carry a DOT date code of 4220 — manufactured the 42nd week of 2020 (October 2020), making them approximately 5.5 years old. This places them at the upper edge of the 5–7 year service window that industry guidance generally recommends for RV tire inspection and replacement, regardless of remaining tread depth. These are heavier ST215/75R17.5 LRH commercial-grade tires designed for the unit’s 22,500-lb GVWR. As part of pre-purchase due diligence, Your RV Broker strongly recommends that prospective buyers have all tires evaluated, and is happy to discuss tire-replacement options at the time of sale.
