New tires and rims!

Cosmic Kustoms · January 25, 2022

Upgraded to 20” Chrome LTZ rims and low profile tires! Love the look. Looking at it now I think I would have gone with a tire that has a bit more sidewall. At first, the tire shop I had install these tires don’t even BALANCE them! They rode terrible. Afterwards, it’s a whole lot smoother. Only thing is that now because of the low profile the ride is still a little rough. Mainly on stretches of freeway that aren’t so smooth… Nothing I can’t live with! I’ve been debating between 4/6 and 3/5 drop for the longest but I think I’m just going to start at a 3/5 for now and eventually get a little bit more beefier tires. Maybe a 265/50r 20

I love the look of a 4/6!!! It’s what I really wanted but I only worry about clearance issues. We have a lot of dips around here and I drive a lot of freeway miles. I do plan on installing helper bags ! But as for front clearance I’m unsure

Here's a 4/6 next to my +14"

20" difference back bumper height.

Do the 4/6 sir

Wow nice! That looks awesome. Maybe I just will do the 4/6… everyone says I should so I think I’ll listen to them lol. I bought the Hypertech Speedometer Calibrator this morning so I can correct the speedometer. Didn’t think the difference in tire size would make the speedo be off by as much as it is. It’s only about 3 MPH on the freeway but in the end I would just rather have the truck running good and shifting right !

Do you remove the lower air dam on the bumper for more clearance?

You could remove it. I would do the drop and see how close it is to the ground.

4/6 on a K2XX is really not that low. A lot of people around me do a 5/7 or 6/8 and I live in a city with some of the worst roads I've ever drove on. Helper bags will be good if you still tow.

I would remove the air dam just because it looks ugly, if we are talking about the same air dam

Thanks ! That's good to know. Honestly I think I might regret my tire size choice lol. I took the tires in for balancing but man they still get bumpy on the freeway. Dunno if it's the tread or not. I'll see how long I can live with it. Might upgrade to Michelin Defender LTX 265/50r 20 in the near future. Rn I have Goodyear Eagle GT II.

The air dam I mentioned is the lower part of the bumper that seems like it'd get hammered on steep dips and driveways , mine actually looks like the previous owner might've jumped a curb at some point cause the passenger side looks a little shredded lol

Post a picture of it, I think I know what you are talking about but want to be sure.

No idea about those tires. I am at 265/50r20 on some Falken tires I believe. You may be able to get some taller tires in a K2XX though

I think we’re on the same page. The air dam I was talking about is the lower part of the plastic lower bumper that can detach. It’s a really skinny long piece

Yeah take that off it looks ghey

Definitely gonna do that then! And definitely once I get some more $$$ gonna get new tires. These look cool but eh the ride isn’t worth it. I had a GMT800 (06 RCSB Silverado WT) and this is the wheel and tire combo I wanted. I know a lot of guys run 275/45 20 on GMT800s so I thought we’ll since i don’t have the cateye anymore might as well do it to the K2XX I’m a noob to trucks so yeah I guess I didn’t think that over lol. I’m so used to tuning with carburetors and lowering with blocks and cutting springs this is all brand new to me !

shakenfake · January 26, 2022

Like I said I run that 265/50r20 tire and wheel setup on my truck. 2/4 drop but I think I am a bit lower than that on the front. This is my fitment

As you can see they fill my wheel wells up much more than yours. I would be looking at bigger tires.

Another option on the air dam... On mine and it looks like on yours the license plate mount is part of it. (Although my Silverado isnt dropped but leveled instead ) I didnt want to drill holes in bumper to mount the license plate so the air dam had to stay. I always thought that it just sat too low. I came across several threads here that mention it is actually 2 long pieces screwed together. You can take the bottom part off which will give you more clearance and just put top half back on.
