Hi guys I am seeking help with the wheel/tire combination that I have decided to put on my truck.I want to put on Pro-Comp Rockcrawler series 97 black wheels on my white 1994 GMC Sierra K1500 xcab.They are 15x8" with a 4.5" backspace. The tires I have chose are 33x10.50-15 BFGoodrich a/t KO.I need to know if these are going to fit without any problems such as rubbing the frame or bumper.I don't think they will rub the bumper because I took off the plastic air dam and did a 1.5" t-bar crank a long time ago to level it out.Both these things made it sit higher and leveled out.Some people have told me that this combo is not going to fit my truck so I have come to this forum for advice. Please help me out!!

Thanks,
Trey

 

It won't rub dude. Relax.

The only thing you have to worry about is people making fun if you for getting wimpy *** skinny tires. WTF? 33/10.5? I've got 33/12.5s and they look skinny to me....

 

I just put 33 12.5 r16 on my 1990 reg cab 4x4 with no rubbing at all so far.

 

They won't rub, and you can go wider. I have 285/75R16 (roughly 33x11) on my stock Z71 and they don't rub.

 

What rim are you running and what backspace??

 

Mine are on the factory alloy wheels. I'm not sure what the specs are on them.

 

Mine have all been the 4.5 back spacing.
