I just put American Outlaw Bunker wheels on my truck they are 18x8.5 with a +10mm offset. The stock wheels are +31mm offset so it actually negatively offset from stock -21mm. That being said I have a Truxx leveling kit and im running 34/12 Nitto Trail Grapplers and I had to do small fender mod as described on this forum by Nor Cal Nick. Once I was all done I fixed the rubbing but it is still a really tight fit. Based on the info you gave me and my limited experience, I think you will make them fit (just barely) with the small fnerder mod and a leveling kit. I will soon being doing a BDS six inch lift to completely solve the problem.........

 

Well, went with the 18x9 Dropstar 645 with 4,5 BS and -12mm offset.

Looking at tires now...going with toyo mt's but unsure of which size yet

Either a 285/70R18 (33.7) or 285/75R18 (34.8)

The bigger tire is almost 30 dollars cheaper per tire...

 

Here is my truck with 18 x 9 XD Hoss with -12mm offset and 33 x 12.50 Toyo MT. It works with trimming and leveled. In NO way will you fit either of those tires you listed without some major hacking or a lift.

Save the mess and energy and order a 33 x12.50:

with a -12 and that wide of a tire you are going to need some trimming. the 75 will require much more than the 70.

Sorry homie but the 285/75 ain't gonna fix without massive rubbing

Both are very correct.

 

post some pics once there on. i was looking at the dropstars too

I ain't scurred on trimming. Will be a few weeks till they're on. Still snow on the ground here and lots of salt

your truck looks good.

Thanks for the replies, makes me re think a few things.

I would like the bigger tire of course, my buddy runs a Kelly Safari TSR with a diameter of 34.8 on his truck with a 16 inch rim with a 0 offset. He has 2 inch blocks and keys in the front on his 02 Duramax.

Will that -12mm offset make that much of a difference on my truck to where it will rub even with the same type of "lift" he has? And remember, that 285/75R18 is 11.22 inches wide instead of 12.5 inches...

I appreciate all the help a lot...just trying to see where i stand with what i want. And I am also not worried about it hitting the front bumper or valance, since that is going to go in the scrap bin and i will be building one.

 

Why the bigger tire? What purpose will it serve?

I know that the 285/75 is a narrower tire, but won't change a thing with the wheel offset. It is still going to rub. Things to consider with a "key" lift are CV angles, ride quality and what clearance you still need on the backside. I understand you are scrapping the front bumper. You still have the inner fender to contend with. I rubbed some and was just careful with mine at full lock. I can't imagine how bad it could be with a taller tire.

Would a 0 offset be a better choice?

Yes it would definitely help, but a shorter tire would be the biggest help. Just trying to make sure you won't regret.

 

Would a 0 offset be a better choice?

 

I have 285/65R18's, -12 18x9's, torsion bars maxed, still rubs, this is a 32.7" tire from the manufacturer specs.

 

Hmm, I'm still not decided on tires i guess. Think ill be ordering the 0 offset, since i can always get 12mm wheel spacers to bring the rim out if i would like

 

truck is nice

 

Well whenever I got confused for choosing the rim for my truck I simply go GMC Truck Wheels Rims - Buy OEM Wheels/Rims, Aftermarket Lights & Mirrors w/Lifetime Warranty. , it will helps me a lot for choosing correct and suitable rims for GMC, well you should also try this, it surely helps you.

 

OP, did you ever get the tire and wheels? I'm in the same boat right now. Trying to decide between 18's and 20's and what tire to run. Only going to level my truck for now. I like the dropstars and looking for some reviews on quality.

 

large fender mod is your friend. i havent done it, but it looks pretty easy and quick...crank keys and you can fit 35s with a small positive offset...
