Can I put these rims on my Reatta?

After much deliberation, I have decided on the wheels that I want to put on my '89. They are 17" X 7" Cadillac DTS rims.<BR> <A HREF="http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1848506596" TARGET=_blank>http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1848506596</A> <P>A couple of questions.....<P>Will they fit?<P>What tire size should I use? <P>(I'm not particularly worried if the speedometer is slightly off as I tend to drive too fast anyway, but I wouldn't want it to be really far off.)<P>I would hate to spend big bucks putting these wheels on the car to find out there are clearance problems, any advice would be apprieciated.

JJ (Jerry Sellers) has all the experience with these swaps, he has a set of 16' x 7" Caddy rims on EBay as we speak. I think he's done the 16" swaps a number of times-not certain on a 17"<BR>Ask him. wink.gif" border="0

You should have no problems with those rims....however, I too think they are on the high side $$$ Keep an eye on ebay and you should be able to get new take off for under $1000... the place selling the rims pictured apparantly takes rims and has them chromed and they are in the business of making money.<BR>Look for a better deal.<P>If you choose the proper 17" tire, your speedometer should stay correct. Checking an earlier post about 17" and the size that owner choose was 225/50r17. You can play with the sizes at <A HREF="http://www.powerdog.com" TARGET=_blank>www.powerdog.com</A> <BR>What you are looking for is a rim/tire combination that has the same revolutions per mile as your original 215/65r15 tires.<BR>You will not find an exact match but anything within +/- 1% will be fine.<P>Example...215/65r15 is 776 rev/mile<BR>225/50r17 is 780 rev/mile or +0.6%, about as close as you can get.<p>[ 08-03-2002: Message edited by: Barney Eaton ]

Rawja: <P>I've done seven switch-overs, but they've all been 16-inchers. Tried a DeVille Touring Sedan 17-inch wheel/tire (don't remember the size of the tire, but it was off an '03) and the clearances were a little too tight. Plus $1100 seems very high for a set; I paid $900 for a set of seven-spoke '02 STS chrome wheels with new tires. Check eBay for these two sellers: ngobros2000@aol.com and going*going*gone! Both have great prices.<P>Jerry

My experience with GM rims is that the later cast aluminum wheels have a size and offset cast somewhere into the reverse side of the wheels. My 7" factory wheels all have an offset of 46 mm (reads something like "16x7x46" - not at home as usual so cannot look).<P>Do not know which do and which do not though.

I just got my rims slapped up on the car, some 17 inch rims with 225/50-R17 Nitto 450 Tires. Here are some pics.<P><A HREF="http://www.geocities.com/itsguild/DSC00075.JPG" TARGET=_blank>Rear Rim</A><P><A HREF="http://www.geocities.com/itsguild/DSC00076.JPG" TARGET=_blank>Side View</A><P>Now just to figure a way to rid teh giant wheel well space. Any solid ideas?<p>[ 08-03-2002: Message edited by: 90RedReatta ]

What is the bolt pattern size on an '88? I want to put some wheels on this thing that would give me a wider thread instead of these narrow little tires. For example would some 225/14/75's work on this? Is wheelwell clearance a problem with wider track rims?

I was wondering if the effective tire circumference of a 225/75/14 or 225/70/14 would be about the same as a 225/65/15, so as to keep the odomoter accurate. I did this on an older Honda, changing from 185/65R/14 to 175/70R/13 without effecting the odometer. I had to buy the wheels of course, but over 210,000 miles, I saved a lot on the lower price tires.
