Tires are not directional Murray so you can rotate left to right as sizing is different front to rear but realize unless you reprogram your sensors they will be register pressures on opposite sides on your dash
Oil Change schedule changed??
- Thread starter DCV1
- Start date

Not on tires that are directional! lol
So you got nothing!
Hmmm I realize I cannot put the left wheel on the right because the tire would be facing backward, but if I take the tire off the left wheel and mount is on the right wheel still directionally correct but the lettering is inside isnt that OK?
I sent off a note to Michelin. The Michelin Canada site does not list the All Season so I have asked about that and rotating both versions. I have to admit I never rotated tires on my C4 or SLK350 so not sure how critical. I did see
And so if the first is the most important I will do it once not knowing why the first is most important

It will say on the tire wall if it is rotational. I couldn't see it on the tirerack web site.
I just went out to confirm that the A/S are not directional, though they are asymmetrical
LOL, Well, I bought one from Tirerack. Now that I look, I can't find them! HMMM
How can they put them on Canadian non Z51 cars at the factory?
Ya, those are summer only tires
The new Pilot Sport 4S's are not directional. They can go side to side on the same axle.Not on tires that are directional! lol
So you got nothing!
Actually those are the correct All Season Tires so this is getting stranger because Michelin told me they dont make them. Plus when I looked at the Michelin site I did a search by 2020-21Chevrolet Corvette and these did not show up. I also notice Michelin lists them as 70k km warranty but Kal tire says 50k km I give up !
It keeps changing! They weren't there earlier.
<shrug> I give up also.
As others have stated they are not quite directional, but they do have an orientation as shown here. They tell you which is the outside.
As long as they were mounted correctly to begin with! lol.
Not sure why you'd want to other then it's free!
I got my 2020 so late in the fall that it hadn't even been broken in yet and when I took it out in the spring I got a reminder the oil had to be changed. Had less than 800 kilometres on it. The dealership said I had to change my oil by either miles or age. So I'll probably have to change it in the spring again.
The oil life monitor system uses a date based countdown and also a mileage algorithm. For date based it is one year. The reason is the additives will wear just being in the engine and contacting air, fluids and metal. Most companies put the date based countdown at 1 year although that is conservative.
The mileage based oil life depends on how the engine is run based on sensors: how many cold starts, how many short drives, how high temp, acceleration etc. For example I change the oil just prior to storage in the October. The date based countdown reads:
Nov 93%
Dec 85%
Jan 78%
Feb 70%
Mar 63%
Now I take the car out of storage and 2 possibilities:
1) I do long highway drives. In this case I may be able to go about 20k km.
2) I do short, city, spirited driving the oil life monitor will indicate change about 12k km.
If I do less than these miles the indicator will revert back to date based and tell me to change in October. So if you are going to change the oil yearly and store the vehicle, its best to do it in the fall. What I do is if I need the oil change in the summer due to mileage, I do one but if September I wait and do it in October.
Not clear.
1. Does this apply to Canada?
2. This does NOT explain what happens to the 2nd free oil change. Our 2020 came with 2 free oil changes, I think that had to be used up in 2 years.
So if you drag out your first oil change to 2 or 3 years, do you lose the 2nd free oil change????
3. I can not believe that of all the users on this forum, that nobody has a contact at GM Canada to query. Anyone?
Thanks.
No. I contacted GM Customer care and really hounded them about the differences in US and Canada as far as free service. In Canada the 2020 and 2021s get two free oil/filter changes that must occur in year 1 and year 2. The 2022 includes DCT filter change. I hope everyone in Canada with 2020-21 contacts GM and maybe they will respond with additional DCT service but soon it will be too late.
