Hello everyone,

I’ve seen this issue talked about on this site a couple times; however, I just want to make sure for my specific instance.

Today I got a tire swap over to winter tires (I run a staggered setup), previously I had 275/35/19 on the rear and 245/40/19 on the front. This time around I swapped over to 265/35/19 rears and 245/40/19 front, and after about 10 minutes of driving my AWD light started blinking (about once a second). I drove home and didn’t notice any issues, but I just want to make sure I can continue to run this setup for the winter or if it could cause worse issues.

So I am quite certain it is because of the rolling diameter difference. On most posts I read 3% difference prior to buying the tires, but now I’m seeing a lot of under 1% difference. My current ones are at a ~1.5% rolling diameter difference. Could this cause any major issues and is there anything I should look out for?

Thank you.

 

I’m going to follow this thread. I don’t play on changing my tire size from stock, but will be interested if that’s all it takes to trigger all wheel drive light. It will be interesting to see if others have encountered this issue and the cause.

 

I wonder if you risk damaging your transfer case if you continue to drive with the warning light flashing.

 

For awd stagger setups, its best to stay under 1%.
