'99 Corolla lug nut taper specs?

[dimwittedmoose51]

Tried this post on the wheels and tire forum with no response, so I'll try here.

My son has a set of Pirrelli winter tires mounted on Ronal alloys off an 83 Audi Coupe GT and the bolt pattern is the same as the Corolla, the offset out maybe 20mm, tire size only slightly larger(195/60/14,but we're not sure where to get the taper design/info on the Corolla lug nuts. Comparing the Audi wheel bolts and the Corolla nuts, they appear to have similar or identical tapers, but I'm asking the forum if anyone knows for sure. The nuts are getting 7 full revolutions before tightening up, so stud length isn't a problem. The holes on the Ronals are recessed enough that it's hard to tell how much contact between wheel and nut there really is. Yeah, I guess I could buy some Prussian Blue or other toling dye and maybe see that way, but surely this information is somewhere within the Corolla Nation.

Don't have to have the Ronals on there, but they are already nitrogen filled, and it would save me the hassle of finding winter rims for the Corolla. Wasn't sure how to phrase a search criteria for something like this, so a link to a previous post would be more than okay.

TIA

Most of the lug tapers, especially if the wheels use the deeper - so called, spline nuts of the past or now known as tuner lugs - are wheel manufacturer dependent. Doesn't mean that you couldn't find one that is pretty close now. Most use a 60 degree taper on the end of the lug. As long as the hub of the car fits within the mounting pad of the wheel and the bolt circle is the same - you should be OK.

Corollas are considered hub centric in design (actually more are a combination of lug and hub centric) - meaning that the wheel rides on a fitted flange on the hub and the back side of the wheel pad - the lugs just hold the wheel pad flush to the hub. But that doesn't mean you couldn't run a lug centric wheel, one that is centered and held in place just by the lugs (hub centric will already be centered before you install the lugs). Many aftermarket wheels can be made hub centric with the addition of hub rings (usually made of heavy-duty plastic or aluminum), otherwise you just use the taped lugs to center the wheel onto the hub. Just make sure the wheel is centered perfectly as you can get them, and check the lugs fairly often to prevent "surprises" down the road.
