I'm supposed to be getting my truck back from the body shop on Tuesday andddd.......

I'm buying a set of machined black Rockstars and need to know for CERTAIN if they'll work, I've got a 06 KC SE 4x4. Completely stock.

Going with 18X9. 6 on 139.7 (5.5). It says the offset is +00

Will these wheels work for my truck?

The offset is a bit agressive for your truck but should work depending on the tire size. What tire size do you plan on running?
Stock 265/70/18's.

You should be good to go with your stock tires. My guide shows these will be flush with your fenders.

What guide are you looking at, I am looking at changing out my 18" wheels on my 06 CC LE 4x4 and want to put 17's on and need to know the offset I need to look for.

I have an internal fitment guide. What look are you going for with your truck?

The backspacing on those are 6.18". Stock is 5.5" so they are tucked in pretty far, 0.68" more, probably better for a street tire. This also means the rim will only stick out 0.32" more than stock.

A better setup would be their 5.71" backspaced, (+18 mm offset on a 9" rim), version. This rim will stick out about 3/4" more than stock rims.

What if i got the 20x10. They're backspaced 4.79". How would that look?

Not so good. They would stick out almost 2.75" more than stock and would cause the tires to rub bad when turning. Even with a stock tire, they would rub.

Yea, i figured they would rub, and i dont feel like doing any cutting so ill probably go with the 5.71" backspace. thanks

There are a lot of Titans running LT325/60R18's on stock rims, and they are a little wider than the 12.5's. Toyo has them listed as an 8.5" width minimum, but when I ran mine in a LT295/70R17 on the 7.5" O.R. rims, they were supposed to be on a 8" minimum, and the 1/2" didn't cause me any issues. They handled the curves great and lasted 37K miles ... pretty good for no freeway driving.

Yall really seem to know your stuff. All of those offsets are like chemistry formulas to me. I have a stock '08 Crew Cab Long Bed Titan. I need more ground clearance as I am constantly bottoming out anytime I'm not on asphalt. I'm looking at bigger tires and planned on getting rims also. I know the stock tires are equal to 32.6" and the most popular size that I've been able to find are 275x70-18 (33.2"). I've also found a tire I like that is reasonably priced that is a 295x70-18 (34.3"). I planned on getting the Bilstein 0-2.5" adjustable shocks for the front because it just doesn't look like a bigger tire will fit in there without rubbing. Anybody have any insight on this?

Also what bolt pattern and offset do I need for rims? I don't want the tires to stick out of the wheel wells.

Mine are +00 offset and they are flush with the wheel wells. 6x139.7 or 6x5.5 lug pattern will work for your truck.

Leveled, by Bilsteins or other methods, the least likely rims to cause the LT295/70R18 to rub will be the stock 18's or and aftermarket rim with slightly more backspacing. Stock is 18x8 with +25 mm offset, which on a 8" rim gives 5.5" backspacing. With an 5.75ish inch backspacing on a 8" width aftermarket rim, you will be a little better, (at avoiding the Pinch Weld Mod .... see link in my sig). On a 8" rim, that would be around a +32 mm offset. Some aftermarket rims will rub the brakes though, so they end up having to have some grinding or wheel spacer have to be used.

If you went with a 9" rim with a +18 mm offset, the backspacing, (how far the rim sticks in), would be about 5.71", but because of the extra width, they would stick out 3/4" more than stock, so would be a lot more likely to rub at the pinch weld, (not as bad as a -12 mm offset though, which stick out 2" more than stock).

Or if you stayed with an 8" width, but got a smaller backspacing like my 4.5", (which also sticks the rim out, then rubbing will be bad, since they stick out 1" more than stock 8's).

And yes, the bolt pattern is 6 on 5.5", and is also listed in metric as 6x139.7
