Military is running the XZL at 75 mph all day long on the JLTV. It's a non issue.

Prices for Petlas RM910 and RM900+ tires vary significantly by tire size and retailer availability. Since these are heavy-duty military/industrial tires, shipping (freight) is often a major additional cost (typically $200+ per tire).

1. Petlas RM910 Prices
The RM910 is an all-terrain, high-load tire often used on expedition vehicles (like Unimogs or converted trucks).

• Size: 335/80R20 (12.5R20)
  • Best Price: ~$853 per tire at Mascus (Marketplace listing, check current availability).
  • Alternative: ~$1,124 per tire at Buckstop Truckware.
  • Note: This size is popular for lifted trucks and expedition builds.
• Size: 395/85R20
  • Best Price: ~$984 per tire at Budget Truck Tires (Note: Often listed as backordered).
  • In-Stock / Marketplace: ~$1,189 per tire at eBay (plus ~$220 shipping).
  • Retail: ~$1,400 - $1,600 is the standard list price at major specialized tire retailers like Tires-easy.
• Size: 16.00R20
  • Price: ~$2,196 per tire at AZ Tire Warehouse or OTRUSA.

2. Petlas RM900+ (Plus) Prices
The RM900+ is a similar heavy-duty off-road tire.

• Size: 14.00R20
  • Best Price: ~$709.50 per tire at OTRUSA.
  • Alternative: Listings on Tires-easy typically start higher, around $1,264, though this may vary by specific ply rating (20PR vs 24PR).

Buying Advice

• Check "Ply Rating" (PR): These tires come in different load ratings (e.g., 18PR vs 22PR). Ensure the cheaper tire isn't a lower load rating than you need.
• Freight Shipping: Because these tires are "oversized," almost all sellers will charge LTL Freight shipping. If you have a commercial address with a forklift/dock, shipping is usually cheaper than delivering to a residential driveway.
• Availability: These specific models are frequently backordered. It is highly recommended to call the retailer (like OTRUSA or Budget Truck Tires) to confirm physical stock before placing an order.

These tires need to be replaced at 10 years MAX from the DOT date. Period. End of discussion. Full stop. 7 years is the max for mounting. 10 years from DOT is EOL. Or you risk death in a roll-over. Condition, storage, tread, appearance are all completely and utterly meaningless. You buy NEW tires and you keep them for no more than 10 years if you like breathing unassisted by machines. When these fail they delaminate and the sidewalls get chewed by the rim and the asphalt. Unless you pull over immediately they will appear to have ZERO sidewall. That will occur in 1/4 mile of driving at 5 mph once the tire is deflated. It indicates nothing about how or why the tire failed. It failed from rubber deterioration due to age. Nothing more.

These are the general Army guidelines and what units with experience Motor Sargents will stick by regardless of command trying to say that weather checking is "cosmetic" - that's how soldiers get dead on US freeways in peace time.

I can attest to that. Before I realized this, I had a 13 year old tire disintegrate at 10 miles an hour. Didn't realize I had such an old tire. Now mine are 4-7 years old, and will not go older then 9 before replacement.

There have been several accidents involving VFDs and old ndt tires on brush trucks. The Texas Forest Service has issued advisories.

I have a number of tires with a 158M designation right below the tire size, and couple with K. What does the M mean?
