275/55- 20 to 275/60-20 and rear lifting block removal

275/55- 20 to 275/60-20 and rear lifting block removal

Postby John F [OP] » Oct 22 2019, 12:43pm

I have a 2013 GMC Sierra Z71 4x4 with OEM 20" wheels and 275/55-20 tires. It has about a 2 3/4" rake. I'd like it to sit a little more level, but not totally level since I haul dirt bikes and tow a light trailer now and then. I also don't want to lift the truck at all if I can help it. I looked at the tire charts, and found 2 entries where it looks like I can get 275/60-20 tires in there without a problem. I'd like to do that to fill the wheel wells a little bit more. Can anybody confirm? Anybody done this and removed the lifting blocks in the rear? Removing the lifting blocks looks like it'll drop the rear a little more than 1". Any thoughts? Thanks

Removing the rear block will drop it down exactly 1in. And will still have a little rake. I did it to mine for a while.

I think you may need a little help in the front to fit the 275/60r20s they are a 33" tire. I had to level my 2009 to fit a 33 with no rubbing.

I have 275/60/20 Michelin Defenders on my '13 with a 2" front level. The tires are 32.6" tall and I get a very slight rub at full lock either direction. You'll have to do something to the front-end if you want to run the 60 series tires.

I'm running 275/60R20 KO2 on my stock 20" wheels (2008 Silverado) and I get slight rubbing as well and that's with a 2.5" level. It's only a full lock and I haven't looked to see where it's rubbing but I know it's plastic. My level is Halo Coilovers with forged UCs and diff drop bracket.

Like GBSierra said, you'll likely need to lift/level it to prevent rubbing at stock height.

Thanks for keeping me from making a mistake. I’ll probably lower the rear and stay with the 275/55s.
