33s AND NO LIFT

RN12CT · May 7, 2019

Hello, do you think I can run 33x12,50 on 17x10 -30 offset on a 2014 Silverado Z71 with factory lift of 1.20 inches ?

Sorry for the boring question.

No. I'm running 33x12.50 on a -25 with a 2.5 suspension lift & had to norcal cut to make it work. That offset would rub on just a 2 to 3 inch lift. People claim you can do it. In my real world experience no way. Unless you like extreme rubbing and only being able to turn your wheels so far. 6 point turns type of thing. Have to three point just going left or right in a parking lot. You need the norcal trim more than the lift for clearance.

Maybe with a zero offset wheel and a trim

And stay stock height.

GM offered a factory lift of 1.20 inches? How did you get that and what was the RPO code? Would be a much better choice than aftermarket, though I have never heard of such a lift except aftermarket dealer installed.

Maybe is aftermarket, I don't know because here in Italy we haven't this trucks officially and the lift was already installed on the truck when I imported it.

I check for RPO code.

By the way the lift is 3cm/1.20inches, do you think I can run the 33x12,50 on 17x10 -30 offset with no problems ?

No you will need to cut away metal.

You’re absolutely correct, so many BS’s in these forums claim their tires don’t rub when they actually do and when they do claim it rubs, only rubs a little at full lock. Same ones that argue with me all day long when I say “Rubbing is not a good thing” and better off getting a real lift in order to fit wide 33’s and bigger!

In this video the NorCal Mod is explained very good but it's done on a 2018.

On my 2014 it's the same work or the truck body is different ?

I have those plates and they make for a clean trim, good value. but if you stay stock height you may need more clearance and there is only so much room to work with. If I remember you said -30 offset, that is substantial. You need a cut and a lift, unless you just want to like a 4"+ lift and could still rub. Most things that clear run zero offsets with a low height lift.

Wide negative offsets can work but require work, not plug and play. Notice all the statements on custom offsets have a disclaimer "may not work for you, even though it worked for the other guy". That's because as Txgreek said most people don't fully disclose the truth that they either have rubbing and live with it, or modded more than what they mentioned.

So you think that cutting and trimming is not enought to avoid tires to rub but I must lift the truck ?
