Default Anyone tried running 5 on 4.5" wheels on 5 on 115m lug

Hi guys, the black steel bullet-hole drilled cop car wheels w/ chrome centers and trim rings I've been running turned out to be bent, enough to have been the cause of my ongoing high speed vibration. I'm done with steel wheels -- I got each pair of the 4 steel wheels from different junkyards, and they are all bent to some degree. Has anyone run 5 on 4.5" alloy wheels on our 5 on 115mm lug pattern? I know this puts some unnecessary strain on the lugs since the pattern is 0.027" off (it will end up being misaligned by around 0.0135" at each hole) but they certainly do bolt up, I test fit a Jeep wheel and it seemed fine.

Thanks

Very, very very bad idea unless you just cruise around at 30mph and never turn. Don't do it.

Your apparent success is not a blessing for everyone to try this. It'* a very bad idea. From a safety standpoint, this is one of the most dangerous things you can do. You can also RUIN your investment. I don't reccommend this at all, much less at freeway speeds.

Wheels aren't running on the lugs nuts, they're on the hub. So while your stuts may fit, you're not having the loads put on the hub like you should. Many aftermarket wheels can require hubcentric rings that put the load back on the hub. Another problem with RWD wheels is that the offsets are very differen't.

Considering the wheels are the one thing that prevents your car from becoming a sled when you least expect it, "close enough" just don't cut it for me.

well u may not recoomend it
take a look at all other GM cars with aftermarket wheels with the 5x115mm 8-10 use the 5x4.5 bolt pattern
what is 115mm / 25.4? it equals 4.527559

im not recomending anything im just saying it works for me and i dont drive like a school girl

I've run plenty of uni-lug wheels on old muscle cars. There are actually plenty of guys running 10 second cars on uni lug wheels. These style wheels have a very large center register that does not contact the hub, and the lugs provide all of the centering and clamping forces. I've never heard of anyone having problems. I'm going to try to find some factory wheels I like in 115mm. The problem here is I need 15x7 wheels, which don't exist from GM, they are all 15 x 6. With 15x6s, which I have currently, there is an unacceptable amount of bulge and sidewall flex running a 225/60, and the tires wear in the center only. I'd rather not go with 16" wheels since I have 4 225/60/15 $130/each Toyo directional tires with 10k miles on them. Jeep Cherokee/Grand Cherokee 4 wheel drive alloys have the correct amount of offset for FWD GM and they have some nice 5 star designs.
