Ram Wheels - 19mm offset vs stock 24mm

[Pertzbro]

Would 5mm less offset cause issues with the brakes or steering?

https://tiresize.com/wheel-offset-calculator/ shows .2inchs tighter in.

Stock Offset is +28mm, fyi. So a 9mm dif is going to be more like half inch in, and that may hit the caliper.

for 20 inch wheel? Just looking to see if a Ram 20 incher would fit fine for winter tire set. Found some cheap takeoffs.

I can definitely tell you there’s a Silverado around my way with 20” ram wheels on it…. No verification about rubbing though. But I absolutely have seen it

The issue is caliper clearance in the X direction (between the caliper and the spokes), not the radial direction (along the inside of the wheel rim). This is where you need the 28mm offset...I think. I put some 20's on I was "trying out" from a 2020 Silverado, had the same 28mm offset...and they cleared ok, but it was within about 2mm of hitting the caliper. Look close at the caliper face, there is a little bump on it which stresses the clearance.

I could have sworn the 20's are a 24mm offset and the 22's are a 28mm offset.

The lower offset will move the wheel further away from the caliper. I have 20x9 +20mm offset fuel wheels on my Denali and there are no rubbing issues.

Alright, i had it backwards. I thought 19mm moved it in, tiresize.com calculator is not exactly clear.

Offset is relative to the rim's center. What you need to focus on is the backspacing of the spokes.

Except the factory wheels have 28MM positive offset and the ones you are considering have positive. You show in this example negative offset.

Use a 6mm spacer to move it out if needed

A lower positive offset moves the wheel spokes away from the caliper. The closer you get to '0' the further away from the caliper you will get and the further out the wheel will stick from the wheel well, and then below '0' into negative territory is when they really start to stick out. This assuming we are comparing the same width wheel.
