Greetings! (and please help with my alignment)

Hello,

I have owned four 1st gen Tundras and have been lurking this forum like a swamp thing for years. I currently have a 2005 limited AC 4x4 with just over 225,000 miles that I intend to keep forever. Here she is : (pic taken when I was in a slight pickle with my boat trailer)



Anyway, the truck is leveled with Bilstein 5100s and Old Man EMU 2884 coils. It also has Freedom Off Road upper control arms, new lower ball joints and new lower control arms and camber bolts. I had an alignment done in June and had new tires installed (Falken Wildpeak A/T3W 265/75R16 116T). Current alignment specs here: Current alignment specs.pdf .

I recently noticed the driver side front tire is wearing on the outer tread faster than the rest of the tread. The passenger side front tire seems to be wearing at an angle across the entire tread surface with the most wear towards the outside edge. I want to take it back to have the alignment adjusted and tires rotated. I have been searching the topic and had found this suggestion somewhere and copied it but I can't remember who to credit: " 0.1 to -0.3 camber, 2.6 to 2.8 caster, 0.1 to 0.2 total toe in. For camber, aim closer to -0.1 if you're mostly driving freeway, and if you like corners/onramps at speed, aiming closer to -0.3 will offset outside-edge tire wear somewhat."

Am I on the right track to fixing my issue? Can anyone direct me to the correct thread to review or offer any other suggestions? I can get some tire pictures and find any other information that might be needed.

Thank you!

 

Welcome.

Alignment numbers are here, in the suspension section: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

Slightly updated recently.

Specifically ask the shop to aim for the following, per our resident expert:​

• • For 'normal' or 'mostly freeway': -0.3 camber, 2.6 - 2.8 caster, 0.1 - 0.2 total toe (0.05 - 0.10 per side).
  • For those who like to corner faster: -0.5 camber, 2.6 - 2.8 caster, 0.1 - 0.2 total toe (0.05 - 0.10 per side).

Is it the passenger front that's wearing on the outer edge, per chance? The camber is probably more positive than you want, I'd dial it back. How does the steering feel to you at current caster?

(Note: I'm not a "resident expert" in this area)

 

The passenger side seems to have more wear over the entire surface than the drivers side with the worst being the outside edge. However, the driver's side outer tread also seems feathered and is a few 32nds more worn than the center tread.

 

Just to eek more details out of you, what PSI are all around on those 265/75r16 tires?

Dr Front:
Pr Front:
Dr-Rear:
Pr-Rear:

 

Unless the rack &/or calibration are off you shouldn't have left front tire wear on the outer edge. As you have -0.5° camber.

But its possible. I saw a vehicle that had a spec sheet 2.7° of cross camber from another shop but was actually only 0.3° cross camber with both the machine I use AND a hand held digital angle gauge.

 

I will go confirm the PSI on the tires and take some pictures. Could the left or driver front wear be a result of my driving style? Be back soon.

 

I just checked PSI on the tires and this is what I came up with:

Dr Front: 30.5
PR Front: 33
Dr Rear 32
Pr rear 34.

I was a bit surprised on the variation as I just checked and adjusted tire inflation about a week ago since I have been towing my boat around a lot. I had set at 32 on the front and back at 34 last time I adjusted. It was fairly cold last night in the 40s here so not sure if that added to variation because one side of the truck was getting sun where it was parked. Overall the wear I'm noticing is not extreme so it does not show up well in pictures. I will go through what I took and post any that seem to demonstrate what I'm seeing. To explain further, on the driver side the outer tread lugs are less worn on forward portion of the lug and more worn on the trailing edge (towards the rear of the truck). The center and inner tread on driver's side seems to be wearing normal. On the passenger side this wear pattern is visible on the outer edge in the same pattern, and is also visible on inner lugs getting less noticeable the closer you get to the inside edge of the tire.

 

BTW, Welcome!

 

Here is a picture of the passenger side outer tread. My description of " less worn on forward portion of the lug and more worn on the trailing edge" was wrong. It's actually the reverse of that with more wear on the foreword portion of the lugs and less on the rear. If I run my hand over the tread I can feel those high edges across most of the tread band on the passenger side.

 

Thanks! It was in the 90s this past weekend even in northern Minnesota where I'm located. Cooled off a lot since then!
