Yep, I run 315/75/16 LTs Maxxis Razrs on Truckus, on NSW rego on 16 x 8 dynamic steel rims. IN NSW you still need engineering sign off for these as well, as the original model was a 275/65/17 and we are only allowed 7 percent increase without certification.
That said, the footprint is excellent , especially when air down to 15 psi for sand , crawling or rock work, and I run at 42-44 psi for the bitumen for the best wear based on my alignment, with minimal wall roll.
