i have a 95 3.0 xlt automatic with a 3" body lift and 4" suspension lift with 33" mud tires and stock axles.

anybody having trouble keeping the alignment set so it wont eat tires? so far have had it aligned 3 times in the last 6 months.

i drive 50+ miles to work, go off road and drive the 50+ miles back home daily.
the off road part is mild trails with smallish mud holes and a few small fallen trees to go over. i drive it easy cause i know if i break it on the trails i wont get home that night. and trust me i so want to sling mud when im in the slop!

 

Something is shifting around when driving.

Are you getting a 4-wheel alignment?

Where is the tire wear?
Only on front?
inside tread or outside

What are "they" changing/adjusting when they re-align the truck?

 

my alignment guy was impressed with the kit i got because it was so complete, including alignment bushings!
yes it is a 4 wheel alignment
most of the time he just adjusts toe but one time he had to adjust camber as well. as far as tire wear, it saw toothes the tires in front bad. and i rotate and balance right after at another shop just to keep the wear even.
he is a one man alignment shop and you can help with the work done! and its computer laserd

 

Sawtooth wear is "normal" on aggressive tread tires

It occurs most on non-drive tires so rotating tires more often will help spread out this type of wear.

Long, straight roads at speed cause the most saw tooth wear.

Description of what is happening:
The larger gaps between blocks means they can move more, so the more aggressive the tread the more wear(saw tooth) it will have at the edges, interior blocks have support on all 4 sides so less deflection wear

Tire pressure recommendations are not specific for use, you may want to try different pressures, maybe get a mini 12volt air compressor and a small air tank, so you can lower pressure for off-road use and then add pressure when you will be back on the road.

 

oh i have a small compressor, because i do air down a lil to get through the sloppy holes!
mostly i take it in when i can hear the tires over the music! lol so your saying i need to switch to agressive at tires instead of mt tires? im running mt tires because i use my truck.it is not a perfect " mud show queen", i have dents and scratches im proud of!

 

You have aggressive tires now, mud tires, they have the "blocks" with wider gaps so can twist and scuff causing the saw tooth.

Any tire that makes noises has the wider gaps, the noise is from air trapped in the gaps trying to get out when compressed as tire is in contact with road

 

the hum dosnt bother me because when the alignment is right the hum is not very loud.
when the hum gets loud thats when i take it in
