Wheel & tire size question
 

2018 Ram 2500 series quad cab 4X4. Looking for input on what would be the tallest tire that would fit without suspension mods and rubbing the fronts in the middle of a turn. Want to fill up the wheel wells better than the stock 17 inch steel wheel and tire combo. Likely going with 18 inch wheel. haven't considered width yet, but don't want them sticking out like the "cool kids". Thanks in advance.

You might want to research / check with dealer before you buy taller rubber. Besides changing final gear ratio, I think tire size is tied into the computer and you could create a real dog unless someone can reprogram.

Thanks. I have somewhat considered gear ratio being affected. With 3:73 rear, I'm hoping it won't be affected too bad. May be best to consider adding 1-2 inches total tire height, instead of filling up the wheel well completely.
I'm not up to speed on what it takes to have a newer vehicle's speedometer calibrated/adjusted. Prior to this truck, newest vehicle I've had is 1998. I'm sure it's not difficult, but not cheap either...

My 2018 Ram 2500 4x4 Off Road package has 275/60/18
and they look pretty nice!
