So on my 1986 SR5 4x4 Extra Cab, I've worn the outside 1/3-1/2 of the front tires and it's been all in the last few months, I'm 75% sure why I just wanted to get some feedback from the community.

So for starters, I torsioned up the front about 2" and put 1-1/2" shackles in the rear, so leveled it out. Tossed the sway bar too (Idea #1). I'm running the cheapo stamped steel offset wheels with BFG AT 31x10.5-15s.

Idea #2 - I just moved up into the hills and I drive my poor old truck like it's a Lotus, I corner really hard.

So I'm pretty sure that my driving style, combined with the torsion up and the lack of front sway is doing this. I'm reluctant to get the 33's I want if I'm just going to tear those up too.

We just aligned the truck, after I bashed in the idler arm and replaced it, and everything was in spec.

Crappy iPhone picture, sorry it's snowing here today, and yes they've been moved to the rear of the truck for now...

 

If you just aligned it, I'd rotate them & see how they do for the next 5000 miles.

 

i have some weird tread thing goin n my taco as well. however its just my front right tire. The outside of it has wear on it and yet my other front tire is fine. I checked the air pressure all are at about 38 39(40 is recomended). I rotated my tires about 3000 miles ago. im sure my truck needs to get re aligned but would it just wear on just one side of my tires and just on that one tire????

 

X2.

You need an alignment and you need to check to see if any parts have excessive wear (other than that one tire).

 

The alignment was done in the spring. It was spot on, I slammed a rock with my idler arm, it gave it 3.5 degrees tow in, I fixed it on the trail (eye ball) then replaced the idler when I got home. Took it to the shop and re-aligned it.

So it's been fine for the season (so far as I know...)
