The short answer

RV tires should typically be replaced at 5–7 years regardless of tread, because the rubber degrades with age and UV. Read the DOT date code (last four digits = week/year) on every tire; aged tires are a negotiating point, not a deal-breaker.

What it means

RVs sit parked for long stretches, so tires age and dry-rot faster than they wear. An aged tire can blow out and cause serious damage to the rig.

Frequently asked questions

Where is the DOT date code?
On the sidewall after "DOT", the last four digits are the week and year of manufacture (e.g. 2419 = 24th week of 2019).
Do I really need to replace tires with good tread?
Yes, age-related failure is independent of tread. Most RV tire makers recommend replacement by 5–7 years.
