Right now I'm running 275/60/17s on my stock height 2000 silverado RCSB. I was looking at lowering it and different things and I did some measuring in my fender well and with the wheels cut it looks like i can only lower it like an inch in the front without them rubbing. I haven't measured my rims but I think they are the 7.5" wide ones. Any input on what I could do? I wanna get 18s and do like a 2/4.

 

you can do a 2/4 with 255/55/18's without rubbing issues, but any lower and you will likely have a problem.

 

if this helps....im running 285/50/20 on a 20x8.5 rim with a 2/4 djm drop and they only rub on the inner plastic fender well(theres a part that sticks out father than any where else) at FULL turn.but as for normal driving their perfect.

 

you could runa 2/4 with the tires you have now...I had a 2/4 with 31.6" tall tires.

yours are exactly 30" tall

 

I have 275/60/17s with a 2/4.. works good.

 

what rims do you have? do you know the backspacing?

 

Weld EVO 17x8, 5" BS

 

Thanks for the info. I'll prolly just go with you guys cause you know a lot more than I do about this stuff.
