please don’t yell at me to search as I did and didn’t find. I’m looking to swap out my rims for 20s with the largest size tires that will fit without level or lift. If I go 20s what offset do I go for and what’s the largest tire I can run
The correct, and foolproof, way to find out is to get a tape measure and get under your truck. I’ll be glad to type it all up for you...
We have already had a member on here who was “told” it would fit and had to buy a lift kit because the wheels and tires he was told would fit, didnt fit.
Here goes. You’ll need a helper to turn the wheel and hold it at lock so you can measure and then turn the other way and measure. You need a helper because if you turn to lock and let go, the steering will roll back quite a bit.
Once you find out how much room you have (btw, it’s not much) then you will have to do math to figure out what size tires you can fit around a 20” wheel.
You’ll need to find out how much room you have on all four “corners” of the tire. Near the inner fender and against the sway bar are very close on stock wheels and tires. If you change your offset, you’ll move the problem to the outside of the fenders so be aware of how your wheel width and offset will effect your measurements.
Offset is done the same way. Measure and do math. You need to understand what offset is, how it is measured and how it changes relative to wheel width. If you already know all this, then you’ll agree that what I have said is important. If you don’t, then you need to do some research. It’s ok, you’re not dumb. I had to research it as well because in the past I’ve only dealt with backspacing I didn’t know what offset was.
I did everything that I have just typed. I practice what I preach. My end result was a truck that has the exact look I was going for and zero rubbing issues. Ended up with smaller tires than I originally wanted, but I don’t have a millimeter to spare.
Thanks a ton. That the same size as the Denali 20s. I’m guessing there’s no chance of squeezing anything else in there. I don’t mind trimming. I just don’t want to lift or level. If those are the biggest tire that fit Any idea what offset I need on the aftermarket rim to fit
