Wheel Height.

I know my 275/45/20 rubbed on mine up front, but I have the jdm 4-6 and my wheels are +18 offset. 1 more inch up front and I probably wouldn't have had any issues.

if that is true those tires will be way too big for a 3" drop up front. the factory tires on Z71's are that tall. The tires I currently have on mine are 28.6 tall and only have a couple of inches of travel before hitting the inner fenderwell.

Im going by the tire calculator on Discounts website. Your 275/45/20 comes out to be 29.74" so I guess we can say give or take an inch and be in the ballpark. It does sound like a big tire for that amount of a drop though.

Well, I bought it with 275 all around. The 275s rubbed terribly so I put 245/45r20 up front after I bought it and they don't rub at all. The Discount Tire calculator is what I was using too.

The stock tires are General 255/70-16's. I would be running a 50 series due to towing. And the total tire height on them right now is 29". I would be running either a 285/50-20 or 275/50-20. Would that ten mil. really make that much or a difference?

You won't be able to get away with that big of a tire on a 3-4 drop unless you are 4X4. If sidewall is that important then you either need to only do a 2-4 or get 18's, or stagger and put smaller tires up front. You would be surprised at how much difference even a 1/2" on either dimension makes. They tires I have now are almost 1" shorter and 1" narrower than the 275/45/20 that rubbed up front like crazy on my 4-6. That 1/2 inch on either side made all the difference in the world. you gotta remember, even the 275/50 is going to be 1"bigger and 1" taller, which means it will be 1/2" wider on either side, and 1/2" more at top and at bottom. Once again, you would be amazed at how much of a difference that is. You might want to think about doing the 275/50 in the back and a 275/45 in the front, that may work with a 3-4.
