1st Tire Rotation by Cadillac dealer - Page 2

st4422 · #16 (**permalink**) 02-11-09, 03:22 PM

At my first and only tire rotation at the dealer, they set the pressure at 35 psi. The problem is that typically the tires are hot when the rotation is performed and so the cold pressure is too low... about 32-33 psi.

It's my understanding that 18" all-season Michelin Pilot HX MXM4 (FE2) and 18" summer Michelin Pilot Sport PS2 (FE3) are both non-directional (asymmetrical) tires, and, therefore, GM/Cadillac recommends rearward-cross rotation for both.

After experiencing the problem you described of due to criss crossing rotation on a prior vehicle; I never ever have criss crossed on other vehicles thereafter and never have had any problems. Our new vehicles have the nitrogen filled in tires versus air; anyone else?

I would be furious with mechanic at dealership and there would be question about them replacing damaged items. I would not let that mechanic work on my vehicle for future jobs either.

Any little scratch is totally unacceptable and the dealer should exchange the scratched lug nuts and buff or re-polish near the center hub. I would go back to the service manger then the general manager of the dealership, if you don’t get a full satisfaction I would call GM and make an official complaint.
I really hate any scratch or dent because I'm the only one who can see them.

I would be irritated. The criss-cross rotation requirement is one of the main reasons I take it to the dealer since it can be difficult to accomplish without a lift. The dealer should always follow the guidelines in the manual unless they can show you a service bulletin that would indicate otherwise.

I don't know if I would get too upset about lugnuts....but the wheels are a different story.

I have the performance tires (PS2's). They are not directional.

I just bought two aluminum race jacks (floor jacks) and some RaceRamps. I'm going to try putting the front on the ramps, remove the back portion of the ramp, then jack both sides of the rear up and place on jack stands, then jack the front up just enough with the floor jacks to get the tires clear of the front part of ramp and place on jack stands.

I've done my own tire rotation 3 times so far with one floor jack and one jack stand. Not too difficult. Just take your time and be careful and place some wheel chocks where appropriate as you go around. Since the rears go straight forward, start with a rear wheel 1st, place a jack stand at that wheel (from this point on you only need your floor jack for the rest of the wheels). Next go to the front wheel (with your floor jack) on that same side, then the other rear wheel, then the opposite front wheel, then back to the rear wheel you started with. Where you need to be the most careful is when you lift the opposite front wheel of the rear wheel that is on the jack stand. Don't forget to torque properly (140 lb. ft.).

On a front wheel drive vehicle, you start this process with a front wheel.

Hope this helps. I'll try to take some pics of the lift points and jack stand points I use. I'll be doing my next rotation Thursday or Friday.

FYI the PS2's are not directional on the CTS. The only specification is an inner and outer sidewall for mounting on the rim - they can be rotated side to side.

Even though I have an STS, I'm thinking lug nut torque is the same for just about all GM wheels. The correct torque value is 100 lb ft (the 140 you mentioin is in Nm)

The rotation pattern is called a "modified x"
Some guys just do what they want instead of looking in the manual to see what GM actually recommends.
TPM resets are a huge issue. To be fair sometimes you get busy and it is hard to remember but if you work it into your routine you never forget.

Wheel damage is not "normal" nor should it be acceptable.
I bought these with my own money to protect your property when it comes to my shop. As you can see they are not that expensive.

When my boss saw me using those sockets he bought 2 more sets for the shop. A worthy investment.

You might ask your SM if he is encouraging laziness or if he is just really unaware that we have moved into the 21st century, but be nice about it.

Wow...never looked at my tires close enough. Assumed they were directional...most Summer only's are.

MY dealer is really good, but I may start taking the cars for service in Virginia.....

Great info! After reading your post I downloaded and printed the product brochure from Astro Pneumatic's website. I'll pass it along to my dealer Service Mgr (after he swore to me that no such product was available). And I'll be nice about it (even though he was not).

ewill3rd, you're THE MAN ... thanks.

It is not the same for all GM vehicles. I was amazed at the torque spec. for 2009 CTS. Please have a look in your owners manual (2009 is what I'm looking at) under specifications on page 5-128. Torque=140 lb ft/190Nm.

According to the 2008 owners manual, you are correct. Looks like a change from 2008 to 2009. I think I'll investigate this more.

I'm glad you brought this up. I'll report back when I get an answer.
