How much does your vehicle weigh
I'm at ~13,500 - 14,000 lbs with the Arctic Fox on w/a long-term, expedition load of equipment.
My rear tires carry 3,880-lbs each when loaded, which is, of course, way more than the 3,195-lb rating of the OEM LT265/70R17 and standard wheels. I looked into LT285/75R17 which are rated to 3,750, so those still fell short of the mark.
The best I can find are the LT295/70R18 E 129 Rated tires, and since the Goodyear Wrangler Duratracs are on backorder - forever - I discovered that NITTO Ridge Grappler tires, in that 18" size, are also rated at 4,080-lbs, which gives me some breathing room, together with the HD METHOD Wheels rated up to 4,500-lbs each.
Sorry - probably way too much info! Ha!
