Like 2 months ago, I went to Big O Tire and got my alignment done. F/R. All the cambers were like -1.1 or -1.2. The toes were pretty bad like 2 or higher all around. My front tires are almost new and rear tires needed to be changed because the inner side worn down. Because i corrected the toe to the rear tires that ALREADY lost the inner tread, do i need to get it re-aligned after changing the rear tires?

 

you might talk to some of the locals in the SoCal regional threads for some assistance.

 

How does changing tires alter the alignment.? Think before posting silly questions.

 

Well, If the alignment is CORRECTED on the tires that are worn down unevenly, then that alignment spec wouldn't be good for the new tires.

 

I may be wrong but I believe alignments are done while the car is on a lift and the condition of the tire does not affect the alignment at all. The alignment should have been done to the cars specs and not adjusted for personal preference (unless you race or something). Unless you told them to adjust it a certain way (which I don't think any shop in their right mind would do unless they know you, as it could turn into a liability issue quick) then you don't need to worry about another alignment.

 

One time i took my brother's g35 too discount tire center for the alignment fix because the rear tires unevenly worned down. Those tires needed to be replaced but i decided to just keep them for a little longer after fixing the alignment (lifetime warranty). The guy told me why fix the alignment on these old tires that need to be replaced. If i change the alignment now, then i'll have to fix the alignment again when i get the new tires. The alignment will be set to the unevenly worn down tires so with new ones, it needs to be re-aligned. I don't trust him fully though.

 

like I said I could be wrong... but I'm pretty sure he was just trying to make some commission.

If the tire was worn uneven, obviously you would want to do an alignment and get a new tire. But if the alignment is right and you've just been rolling on a tire that needs replacing, all you need to do is replace the tire since you already know the alignment is in check.

I may have been redundant there lol. Bottom line --> If you had an alignment done recently then theres no need to worry about another alignment.

 

So ur guess is that i don't have to do the alignment again even though the alignment was done recently on the UNEVENLY worn tire, right?

 

Right, even though the tire was uneven, they should have done the alignment according to the 350z's recommended specs, not a "worn tire spec" or "corrected spec". So when you put new tires on the alignment will still be within the cars recommended specs and all will be well.

I usually use analogies but I can't think of any that would help lol.

 

oh wow. I understand now. They prolly aligned to the 350z spec not the worn tire spec. i hope that's what they did

 

*obligatory facepalm for every single one of your threads*

 

Did you born with all the knowledge you need about cars?

 

The internetz... a dangerous place

 

Correct. The alignment is a "wheel" alignment. You could take off the tires and put them in the trash.

 

You don't need to worry about re-alignment.
