Huge Rear Axle On My TRD Off-Road Trim - 9.5" Upgrade | 4th Gen Tacoma Forum

Decided not to wait for stock Goodyears to wear out. Did the takeoff thing yesterday. Nitto Terra Grappler G3 (and spare, easily fits underneath ) 275/70r18 (barely bigger than stock) seemed the winner after research for many reasons. Sure, would like 34's, but not enough to get outta "SL" land. Nope, not gonna do it. Too much "tax". They are 3 peak snow rated and VERY quiet.

For those wondering, Toyota did give us a lot of what we asked for in this new truck. One crazy important feature, the 9.5" rear axle. This axle is nearly as big as a Dana 60, only .25" smaller. Naturally, they are super strong. You could technically run a 40" tire with relatively little issues. My plan is to run 37s bare minimum in the next few months, and 40s only if I decide to throw it on portals. But I'm beyond stoked on the beefier rear end. Hopefully the front can keep up! The 3rd Gen had a max size of 8.75". While still a good size, these new ones are much better.
