Barney Eaton Posted December 14, 2001 Share Posted December 14, 2001 Any front wheel drive Cadillac wheel (after '86) will interchange with your Reatta.<P>That does not include the Cimarron Link to comment Share on other sites More sharing options...
tcams76 Posted December 14, 2001 Share Posted December 14, 2001 Barney I hope I spelled your name correctly last night; tirerack has a lot of nice GM (front-drive) wheels, but limited for the Reatta. What year does the interchange end or is it any 5x115 bolt pattern?<BR>thanks in advance Link to comment Share on other sites More sharing options...

Barney Eaton Posted December 14, 2001 Share Posted December 14, 2001 On factory wheels you should be safe with any GM front drive wheel that is 5 x 115.<BR>That would be all the big GM cars, the smaller fwd cars were 5 x 100<BR>On aftermarket wheels, the offset varies quite a few mm and could cause interferrence either on the inside or outside. <P>If you do a search on wheels, there was a couple of long discussions with dimensions and explainations given.

padgett Posted December 14, 2001 Share Posted December 14, 2001 Stock offset for a 16x7 seems to be around 47 mm (what wife's Bonneville wheels are marked). The Enkeis on mine are marked 38 mm and the track is almost an inch wider than stock. The lower the offset, the further the tire sticks out, is apparently measured from the center of the wheel.<P>Am told that backspacing is the real way to measure clearance but few wheel mfrs give that. (American gives both - was going to buy Americans until Sears refused to stand by their sale advt. & went elsewhere for wheels and tires) <A HREF="http://www.americanracing.com/wheels/details.asp?wheelid=85&name=Estrella&picture=Estrella" TARGET=_blank>http://www.americanracing.com/wheels/details.asp?wheelid=85&name=Estrella&picture=Es trella</A> <P>Bolt pattern is 5x115mm. Some have said that 5x4.5" (114.7mm) is so close as to not matter. Do not know about that.<P>Did have secondary consideration: wheels I bought were dual bolt pattern: 5x115 and 5x100 so will also fit my Fiero. Americans above are same (note same part number).<P>BTW, even GM wheels can vary on offset. Wanted 15x7s for my Fiero and found a set of<BR>Beretta wheels for a good price. However the offset was about 3mm less than the Fiero wheel. Fronts fit fine but needed 3mm spacers (listed for a Mercedes) on rear for weights to clear.<p>[ 12-14-2001: Message edited by: padgett ] Link to comment Share on other sites More sharing options...
tcams76 Posted December 14, 2001 Share Posted December 14, 2001 The wheel I ordered from tirerack has a 40mm offset, I should be fine. I was worried there for a second with those wider tires(225x60/16). I had dreams of those young cats with the tires sticking out a foot or more from the fender.

tcams76 Posted December 17, 2001 Share Posted December 17, 2001 Question: Was the 1991 Buick Skylark front wheel drive? Tirerack has a wider selection of wheels for the model. Link to comment Share on other sites More sharing options...
padgett Posted December 17, 2001 Share Posted December 17, 2001 Believe the Skylark has the smaller 5x100mm lug nut circle - same as Fiero, Cavalier, Grand Am, Alero, etc. - that GM used on smaller cars. Reatta has the larger 5x115mm circle.<P>Thing I wonder about is the incredible tortional loads these kids put on the wheel bearings with these extreeme offsets which is multiplied if they ever crank into a corner.<P>Maybe that's it: they never crank into corners.<p>[ 12-17-2001: Message edited by: padgett ] Link to comment Share on other sites More sharing options...
tcams76 Posted December 17, 2001 Share Posted December 17, 2001 You are correct, I just called Tirerack and it is 5x100. Oh well, back to plan #1. Link to comment Share on other sites More sharing options...
tcams76 Posted December 17, 2001 Share Posted December 17, 2001 Off topic: I'm in the market for a new socket set. Is the Reatta metric or SAE? Link to comment Share on other sites More sharing options...
padgett Posted December 17, 2001 Share Posted December 17, 2001 Reatta is metric except where it isn't. (Actually do not think I have found anything that isn't but do not know where TORX came from.)<P>Of course is hard to tell the difference between 1/4" and 8mm (screws on ECM) or 3/4" and 19mm (lug nutz.<P>Sensors may be inch but head on serpentine belt idler is 18 mm.

tcams76 Posted December 19, 2001 Share Posted December 19, 2001 Thanks, I just got my '89 owners manual and '89 service manual, final edition from 'Helm'. $20 for one and $90 for the other; they look brand new. I guess my car will be getting all the Xmas gifts this year. Link to comment Share on other sites More sharing options...
