Talked to the Schwab dealer and the guy didn't have any news about a new tire with a higher weight rating. It looks like the heaviest tire they sell for a 16x8 inch wheel is the 285/75 at 3740 pounds. I currently have the 265/75 at 3415 pounds rating. About 400 pounds per wheel more load capacity. I could also go with the 255/85 with the same 3415 load rating. that's the widest tire I'd use on my stock aluminum wheels.
TOYO tires. Click Specifications tab.I also got my front wheel alignment done after discovering I needed to get 4 ball joints replaced. The quote for all was 650.00 but they charged me 552.00 so I was happy with that.
