H3 Hummer Rims on '99 K1500 Suburban???

[1990 Suburban]

I'm wondering if anyone has any experience with installing H3 rims on a 'Burb...

I just acquired a 1999 K1500 4x4 Suburban and the tires need replacements. I ordered some 245/75/R16 Bridgestone Blizzak DMZ3's for it off Tire Racks website, taking advantage of a great "closeout" deal.



I came across a set of 2006 H3 rims yesterday, and scooped them up for peanuts knowing the 6-lug bolt pattern was the same.(6x5.5)

I still have to test fit them for clearance but thought I'd ask first...

Do you think it'll be a problem that the center bore of the H3 rim is the larger 100mm size rather than the Suburban's 78.3 c.b.??? Will this cause the load of the vehicle to be dangerously carried solely by the studs, without the help of the pilot on the drum and rotor? I realize both rims are lug-centric, not hub-centric...I'm just concerned.

Stock Rim 78.3mm CB


H3 Rim 100mm CB


Will I run into any clearance issues due to the wider H3 rim (7.5 inch), over the stock Burb rim which is a 7 inch width?

And I don't have a clue if the offsets are different...



Just thought I'd see if someone has already done it..."Search" came up empty.
Thanks in advance.

Well, I spoke with a few people who affirmed the larger center bore would not be an issue. They all pointed out that most aftermarket rims have a large bore to accommodate multiple vehicles and that they are lug-centric anyway.

I had them mounted and balanced today and slapped them on the Burb as soon as I got home.

Here's a couple pics.
