You guys on this site are quite knowledgable. I'm hoping you can help me out. Does anyone know if a 20"x10" wheel will fit on the rear of a 2009 nnbs RCSB with a 4/6 drop? Being old school, I like the bigger/smaller front to rear look.

 

Yes, with the right offset (+30ish). You're going to go smaller than a 20 on the front? Even 20's look TINY on these trucks with the huge fender wells.

I run a 24x10+30mm on the rear and it's fine.

 

Thanks for the reply. Im gonna run 20's front and rear. 8.5 front with the 10's out back. After looking at all the trucks on this site and others, I think I'm gonna go with 20's. I like JB's truck with the GM 22's. But there was one other black truck with factory 20's with a 4/6 drop that just had a better looking stance. I'm looking at running Billet Specialties wheels.

 

I had factory 20's once upon a time

 

JB, your truck with the chrome GM 22's looks awesome. I wanna run polished aluminum Billet Specialties with a little taller tire on the rear. I live in So Cal, but don't want to copy your truck.

 

lol....10's will be fine with like a 305/45/20...what offset do the offer?

 

I'll have them custom made. Not sure on the offset. My first lowered truck was a rcsb 93 chevy. I recall that everyone ran different size tires and wheels on the front and rear. Just trying to achieve that same thing. With that being said, I've been looking for a nnbs with different sizes front to rear, and haven't seen one yet. Everyone seems to run the same size tire/wheel front and back.

I might be missing something here..........

 

I was gonna do the same thing, problem is you need to run the same dia from to back or it throws codes for ABS etc.

you just need to run some calculations

 

Good point....If I use the same diameter tire front and rear I should be OK. I'm gonna use 20x8 up front with 20x9.5 in the rear. Thanks for your input.........
