Spare Tire Recall

[HammerBoss]

I was at the dealership yesterday getting an oil change and the guy that scheduled the appointment said there was a recall for 2019-2022 Silverados that came with 20' & 18" optional wheels that had a 17" tire. I looked it up and they did recall them for this but when I put my VIN number in there is nothing listed. Anyone got any info on this? Apparently, this may cause the anti-lock brakes not to function if you use a 17" wheel with 3 ea. 20" wheels!

Only 626 trucks were effected.

Yes I saw that. But not sure what that means but mine is done that way and is not included.

It's not the wheel size that matters, it's the tire size. It's diameter needs to match that of the tires on the truck.

So yeah I think that's what I said. The truck was sold new with 20" wheels. (and tires of course) The spare is 17" in diameter. That does not compute on so many levels.

TIRE DIAMETER!!!! You could have a 1" wheel on there as long as the tire is the same diameter as the others. WHEEL SIZE DOESN'T MATTER!!!!!

What part of 20” wheel do you not get? 20” is the diameter.

Diameter of the wheel is irrelevant, its the diameter of the tire that matters.

You do know that the only tire that fits on a 20" dia. wheel is a 20" dia. tire right?

You must also account for tire height to get overall diameter, not just rim diameter. Your spare overall diameter even with a 17” rim needs to be close to your overall diameter with the factory 20” rim.

I try to be nice on here, but you are DUMB. OVERALL OUTSIDE TIRE DIAMETER!!!!! NOT THE INNER DIAMETER!!!

Take a deep breath guys.

So if your factory wheels are 20" rims they will have rather low profile tires (thinner sidewalls) than say the factory 18" wheels do. But if you stood them beside each other the 20" would not be 2" shorter than the 18".

So, a 17" wheel (rim + tire) with a fat tire on it could easily be the exact same height as your 20" wheel (rim + tire).

Another visual way to look at this already mentioned above. In this example a tire and 16” rim and a tire and 20” rim have the same overall diameter.

Any of us (me included) who have increased our tire size and not increased our spare have created a similar issue as the recall... I am running 295/70/18 Wildpeaks that are a 34.4" diameter and my stock spare is 265/70/17 that is a 31.7" diameter. This is a significant difference. If I need to run my spare, the smaller diameter will have to spin faster than the other 3 tires to go the same distance causing the truck to think that wheel is losing traction and activating traction control. Not a big deal for short distances or off road, but will set a MIL over long distance. New tire technology is really good and I carry a plug kit and an air compressor on long trips so I don't worry to much about it, but it is good to know...

Difference in diameter from one side of the rear axle to the other can cause differential damage. I bought an Avalanche and didn't realize it had two different size tires on the rear axle a week later when I had to put new brake pads on. I bought the correct size and put it on as soon as i could. I don't know how long it was on there but the diff blew up/locked up not long after. If you have to run with two different diameters, put the unequal size on the front and don't run it in 4wd.
