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
