Bought my Acadia used last week with 5700 miles on it. Registered it with OnStar and the only thing that seems to be in error is that they say i need a tire rotation allready. The BMW Dealer told me they did an extensive $150 preparation which included tire rotation. If i just relearn the tire pressures after checking the pressures will this satisfy the tire sensor test or must they be reset by a dealer. i am from the old school that says it costs more to rotate tires than to buy new ones when the old ones need it at about 10% less miles.
Any suggestions would be appreciated. Love the Dark Blue SLT-2 FWD.

I don't know about how to reset the OnStar indicators for rotation. Relearning sensors is an easy task, so you might as well try that.

I am not crazy about rotating tires every 6k miles, I probably do it about every 12k on my Mustang or so. are you saying you don't generally rotate at all? I would think that is a little unwise as the treadwear is different for the different positions, especially with a FWD car where steering, propulsion and braking all are centered on those front wheels. I think that 10% improvement in life is a little conservative, it you are really on with rotations and making sure your pressures are right, you can probably get a 20% improvement in life (or diminish life by 20% if neglecting the tires).

And I am not sure about the cost thing. It doesn't cost that much when you do your oil changes to rotate tires, $20-30 I think is common, but a lot of time I find I can do it with coupons from the new dealers, and when I buy a set of tires, then rotation is generally free for the life of the tires. Also if tires don't reach their warranty life, if you have not rotated correctly, it may affect the amount of pro-rated credit you get for the worn tires.

I rotate tires every 10K, keep 40 lbs front and 36 rear in my cars I have had over the years. I have never gone by factory recommended pressures and the treads have always worn even. I probably get a little better mpg too.

True, the long term savings in tire life are nominal, but rotating them isn't about extending tire life alone. Moreso, it is about keeping the treadwear even around all four points of contact on the road.

Due to an extensive number of factors, the front tires on any vehicle invariably wear at a faster rate than those in the rear. Things like added weight to bear due to engine location, bearing the lion's share vehicle brake force weight, accelerated wear due to directional steering, etc., etc. It doesn't seem wise to me that the tires with the MOST extensive wear should be the ones consistently subjected to ALL of those forces.

There's a lot of places where I may tend to be frugal, but tires are not among the things I would skimp on. It is the one and only place where the 4000+ lbs. I'm being hauled around in meets the road. Ultimately, there's a reason why tire rotation is recommended, and that reason lies in this one question I ask myself..............is my personal safety worth the few extra bucks?

Answer: Of course. If fate has it that I die in an accident, it won't be because I had crappy tires up front. Besides, once I'm dead, I won't be able to spend the money I saved anyhoo.

Sorry for the long thread. I'll get off the pulpit now!! :blahblah:

Thanks Everybody.

Its just that are a couple of old farts that don't put over 6000 on our cars a year. Just upgraded to a 2007 DTS and SLT-2. Now OnStar tells us that we don't need oil change for 12000 miles based on their computers (not the old 3000 change of yesteryear). I've heard so many pro's and con's about tire rotation. We trade every 3-4 years and there is always lots of tread on the tires with no cupping or excessive wear but cracks starting to form due to age I guess. Now they want to put nitrogen in them as well as rotate and balance and relearn the sensors so it seems like a lot of expense that just might not be necessary. Gas isn't getting any cheaper and we do need a little money left for Scotch and a little pleasure on our retirement incomes. :beer: :cheers:

Appreciate all your input.

I apologize for not recognizing that we may be in totally different places. I'm still running the rat race every day out on the killer highways so I can have the pleasure of getting to the office and being chained to my desk. Have had a few bad accidents in my day that were no fault of my own that still make me shiver when I think about them. On one hand, I feel like I'm living on borrowed time, and on the other I'm keeping my fingers crossed that I live to see retirement someday ;D

Anyway........Have a Scotch for me, will ya? And enjoy!! CHEERS!! :cheers:

Well the oil change thing is another issue entirely!

I have never been at the lube shop every 3k miles. Manufacturers for every new car I have had have recommended the shortest milage interval being 4500miles, but usually it is about 6k miles- and that is in the maintenance book you get. I will go 6-8k fairly often.

But with the Acadia, before we took our 3000 mile trip, I did have the oil changed with only 3200 miles on the odo. Now extrapolating out the oil life monitor, it will require another oil change at about 16-17k miles. Without trips, that will take 2 years for my wife to put on the car, I just don't see going more than a year between oil changes. I am thinking that as the car reaches 8-9 months old, it is time for the next change (6 months from the last oil change) and the first rotation at that point.

When it comes to tire rotation and wear, be very careful when thinking that you want the best tires on the front. An auto rag a couple of years ago had an article showing that having better tires on the front was actually quite dangerous in winter driving and in rain. If the front has much better traction around a curve, the rear will try to come around on you. I know we have stability control to help prevent that, but there is only so much it can do on ice or during hydroplaning. One of the guys at work found that out the hard way just one week after replacing his front tires only. He spun in a rain storm going around an interstate curve and totalled the car. Even wear/traction is important.

I rotate my tires to get more even tire wear. I want the whole tire to wear out not just the part of the tire that is getting the most abuse at that location. When I replace my tires all four tires are worn about the same. The owners manual tells how to reset the sensors. It's not hard and takes about 10 minutes. You will need a way to put air in the tires to reset the sensors though.

Oil changes are cheap insurance and I do them on a regular basis according to my driving habits during that change interval. If I have been driving in real hot weather, pulling a trailer, lots of short trips or stop and go driving I will change it more often. If I put all the miles on a long trip with little stress on the engine I will go longer, but never beyond 6000 miles. I have never worn an engine out on any car I have owned, and I usually will keep them well past 200,000 miles. If the car didn't use oil when it was new it still will not be using much when I sell it. If you take care of them they will last a very long time. Spending $45,000 on a new car every four years would be throwing my money away in my opinion.

Maybe I should just close my eyes and get the oil changed, tires rotated, and and inspection done once a year. Getting so old that maybe if I get it detailed and have some new car smell deoderant sprayed in I will think I have a new car. Just have to stop listening to dealers and use common sense.

Thanks again everybody

Tires should be rotated every 6K miles. I have noticed some trucks will slightly feather the tires, even when properly aligned. A PROPER rotation will even it out.

This exactly why I rotate mine. When the tires have not been rotated for a lot of miles they get noisy. By keeping the tire wear uniform the car drives much quieter.

Good ? I just got back from NTB having rotation and alignment done, and didnt think to ask ???

I've always brought the back tires up keeping them on the same sides, and cross the fronts when taking them to the rear, but apparently GM thinks it should be the opposite:

The odd thing is that every time I take my cars for tire rotation, they keep the left on the left and the right on the right and just go front to back. They have never crossed the tires like the manuals say. ???

Call me a blasphemer if you want, but the 1995 GMC Jimmy I had before I got my Acadia got 77,000 miles on its first set of tires and 77,000 miles on the second set and was going strong on the third set after 35,000 miles, and I never once rotated the tires. I checked the treadwear occasionally and tire pressures frequently. But no rotating. And no problems.

With the Acadia I'll be checking often to see if its tires present any different wear behavior or problems. If I notice anything that suggests a need to rotate, I'll do it then.

Blasphemer! ;D

Hard to believe you never rotated them. Even once in a while? 15k? 30K? 50k???? Wow.

Nope. Not even once. Michelins came on it and were what I had Sears put on each time as replacements. It will be interesting to see what kind of mileage I get out of the tires that came on the Acadia. Being larger in diameter (18" vs 15"), theoretically they should go even farther before I need new ones.

I rotate mine on all my rides every 5K. Change my Amsoil and Amsoil Filter every 10k with no problems. And my dealer sends me free tire rotation coupons and they call me every month to see if we are happy. Just give me MORE mid-range HP and I'll shud up!
