They are safe but do put more strain on the hub and may decrease the longevity. ALWAYS get hub centric 78.1 spacers. I have 2" I'm putting on next week with my leveling kit.
Measured the new tires. Not even a 34" on stock TB 18s with 41psi warm. That final picture is stock Duratracs next to 60% 33x13.50x15 swamper LTBs on 15x10s. Sent from my SM-G960U using Tapatalk
Installed 35x12.50x18 supposedly 34.6" on my stock TB just now. No rubbing at all on pavement and speed bumps on my way home. Installing a leveling kit next week because my TB has a 3' rake Sent from my SM-G960U using Tapatalk
I'm including my pictures with the same LEDs you used because your pictures don't do them justice. Took me less than 30 minutes with pictures and testing prior to each installation.
