305/55r20 on stock wheels. 2" lift

[Ezekiel2517]

Folks I finally did it. I put on the p305/55r20s on my 6.2 LTZ max tow 4x4.  I have a 2" motofab upper spacer in the front and a 1.5 generic block in the back. My rims are the RST style that I had swapped for when I bought it.  It is damn close to rubbing on the upper control arm but about 1/4" clearance.  No rubbing on mud flaps.  I think I may replace the back block with a 2"

I would love to replace the original 275/60 tires with 305/55 with the original r20 rims on my new 2021 Chevrolet Silverado RTS without any leveling or trimming,, do you guys think is possible???

Do you think the same tire would clear with a 1.5” leveling kit in the front? My truck looks level from the factory, I have maybe 1” rake and you can’t really tell. I really don’t want to lift the back any.

275/60/20 is 33"

305/55/20 is 33.21"

 

Overall Diameter is nearly the same, so no issues there. The extra width is where it gets iffy with clearance and may require a lift and/or removal of the mudflap brackets.

Im pretty sure 305/50 will fit. Might need a .375 spacer.

I know the size, I used to change tires on my trucks like people change socks lol. The OP said he didn’t have any issues with a 2” lift. I’m wondering if a 1.5” would have enough clearance and not rub the mud flap. I’ve have lifted and leveled trucks and really I’m kind of over that $hit, I’d like to keep my stock wheels but put some wider tires on. I wouldn’t be against a 1.5” level as these trucks seem to sit low, but I use my truck so even if I level it I don’t want to do rear blocks. Hell if I could get away with a 1” level I would do that, my truck seems to sit pretty level from the factory..

Did you ever do this?

I'm doing a 2" leveling kit and 305/55/20 Nitto Ridge Grapplers on mine today so I'll take some pics after. Here's a few before pics with stock 275/60/20 tires.
