Verifying that these rims fit & thoughts on looks

[mars2878]

Someone local to me just listed these 20in rims for sale. They are off of a 2025 Yukon Ultimate with 5k miles.
My truck is a 2000 Sierra 2wd.
Both are 6-lug.

So I wanted to verify fitment & if anyone for certain if the 2025 used the same lugnut thread as a 2000, as my 2000 uses open faced lugnuts.

Does anyone know how to photoshop? maybe potentially see what my truck would like with them?


The said rims


Oh, they are listed for $800.

Thanks in advance.

Seller only gave 3 pics, this Rim pic, 1 of the tire size, 1 of the tires stacked to see the tread.

I mostly wanted to verify fitment & if anyone knew if the 2025 lugnuts were the same thread as a 2000 as my factory setup has open faced lugnuts.

But I was curious if someone knew how to photoshop & put that Rim style onto my truck to see how it would potentially look?

Sorry, did not read good enough. Did not see that you had not bought yet.

They should have both the same lug pattern and threads.

Sooo.....on the way to work today, I stopped and picked them up. I couldn't pass up the deal. If they didn't fit, I can easily resell to recoup my money.

So here is a pic of 1-wheel sitting against my truck.

What size are the 2025 tires? I believe my brother is running some 20s on his 2000 RCSB 1500 2wd, but IDK what size they are?

Google/AI says the largest tire diameter you can run on a stock 2000 Silverado 1500 2wd is between 31.6" to 31.7".

You always use one of those coil spring donut spacer to get a bit more clearance if you need to. But there should be no issues on the lug/pattern mounting side of things.

Gonna need trimming to fit those, unless the center is different than pic.

Center??

 

[ORVietVet]

Where the hub bolts up at. That tire is not gonna clear as it sits in that pic. It may be different when bolted up and set in the wheel well.

Might need the SoCal wheel arch mod for 275/65R20, which are 33" tall.
GMT800 wheel arches are normally meant to house 31.6" tall tires.

Gotcha

There's about a 3in different in the height of the hubs. So the truck will end up with a slight lift.

I'm kinda skeptical you can fit a 33" outside diameter on your truck, but I may be wrong?

You can mail in your ECU to get recalibrated to the tire diameter. LT1swap.com used to charge like $75 for that, not sure how much it is now. Or befriend someone with HP Tuners, although you need $100 for the 2 credits to modify your tune, so that's actually more maybe?

You are the 1st person here or my daily run-ins to mention about the possible issues of the overall diameter fitment.
It's mostly people talking about the rim fitment, I haven't noticed talking about the actual fitment of a tire when upsizing.
It's been awhile since I've upsized, so it slipped my mind.
Yes, I did have it on my mind about the speedometer calibration.

Guess my only option is to start mounting them this weekend and see what happens. If they don't, I'll just resell them.

See #12 post.

See #12 post.

Yes, see 14

My hub is about 3in lower than the hub of the '25 rim. Once mounted, it would lift the truck & increase the gap between the tire & the wheelwell. That's a given.
But it might not be enough?
