i have a 2019 silverado with all the shudder an slip problems. I have not received a letter. how can I get involved?

Nice chart you have there. I'm putting on 275/70/R18 tires, I have the 6 speed trans with a 3.42 rear end. My stock tires were 265/65/R18. I'm looking for a chart that will show me the rpm's with different gear ratio options. I plan on getting a tuner as well. I never tow anything. I'm just a city and highway driver. I just want to make sure I don't need a different gear ratio. I don't want to put excessive stress on my trans or engine.

I'm looking for a gear ratio and tire chart for the GM 6 speed transmission. I have a 3.42 rear end and I'm wanting to put 33 tires on. I can't seem to find a chart to reflect the 6-speed transmission.

Thanks everyone for the reply. I think I will stay with stock tires and put my new rims on them. These are called Dirty Harry. Can you see the revolver, lol

I'm new to this forum. Here is what I have..... I just purchased a 2019 Silverado 1500 (old body style) 4X4 with 14,000 miles on it. It has the 6 speed trans with a V8 5.3 with a 3.42 rear end and stock tires (265/65/r18). I had a 2 inch leveling kit put in the front. With a tonneau cover I'm getting 24 mpg highway and 22 mpg city. I just ordered $3200.00 in rims and 35 inch tires for no other reason than the coolness look. The rim manufacture said the new 18 inch rims and 35 inch tires would fit. The stock rims have a 26mm offset and the new rims have a 18mm offset. So....... after I ordered my rims and 35 inch tires It came to my attention that I should change my gearing from a 3.42 to maybe a 4.11. Thats another $2,000 there abouts, I dont want to deal with that at this time. So I called the tire shop and cancelled my 35 inch tires and will put my new rims on my stock tires. Now I'm wondering if I can keep my 3.42 rear end and put 33 inch tires on. I've been reading so much the last few days it is making my head spin. How much bigger in tire size can I go if any and keep my 3.42 rear end? Dont forget I have the 6 speed trans with a 2 inch leveling kit in the front. Can anyone point me in the right direction? Thanks GM Rat
