Irregular tire wear

[craig_mc]

I have a Gen 1 with 135K on 315 BFG KM3s. The front tires are wearing irregular with rows that are showing road contact and adjacent rows that are not (and they are actually worn down more). They are also very loud and have a “womp, womp, womp” sound at low speeds. Looking for advice. Ride is stock other than the tires.

Side note…just purchased BFG 37” K02s and am asking opinions as to what I should do on the front and back suspension. Thinking mid perch Geisers for the front and 2.5 Deavers for the rear?

Any issues with tires first and parts later if I plan to stay on the pavement until I get the parts?

How many miles on this set of BFGs? What air pressures are they set ay? When was your last alignment?

Would also like to know how often you rotate the tires, and if the shocks have been rebuilt. This type of wear can be caused by several factors

25K on the KM3s, 2years since last alignment, rotation at 10K and 20K…now at25K. Stock shocks, never changed or rebuilt. 45 psi on all four. Thank you for your advice.

45 psi in the tires? WAY to high.

Dude, shocks need to be rebuilt. Should have twice already.

Rotate tires every 5k miles with the oil change.

Rebuild your shocks, replace the tires, do an alignment. I'd also look at the front end bushings and tie rods for replacement.

@Nex for the win.

Do NOT mod with a known problem. I wouldn’t do tires until you have the $$$ and time for the bushings, tie rods, shocks and alignment. The new tires will just get shagged along the way the longer the repairs wait.

^^^^ What he said

Thank you. Any advice on new shocks and springs with 37s? Thinking mid perch Geisers for the front and 2.5 Deavers for the rear?

Beautiful truck! I had a 14 Ruby Red SE that I bought new. Love the SE graphics and wheels! I can't help on the suspension and other mods needed to run 37s, but agree with the advice concerning rebuilding your shocks and that you're running your air pressure way to high.

Check all the other things they've mentioned above, and repair/replace as needed. Once you do this, you'll feel like you bought a new truck...lol. Going to 37s could start a whole new set of issues that you may regret unless you like wrenching on your truck. But having 125K on original shocks prompts this warning more than anything. Good luck!
