Humm I found a posting that Chuckie B has 275 on his rear and it does not look to bulge at all which is why I think it may be a 17x9 rim? I wonder if it's safe?

I've run over 200 passes on mine ranging from 12-16psi. If it was going to blow off a tire it should be doing it with launches or running over 100 in the traps. I would feel confident telling you that it will hold up as it has for me.

Well I did it. I installed the rear 275/40/17 Toyos today and it looks nice. I had the shop measure the rim and it is a 9 inch so they fit nicely. I guess these are a variation of the cobra rim.

May cost some cash, but Try a "Rubber bullet" Craytex wheel on a dremel tool to buff out the scratch, then use a wire polish head for the dremel with a decent amount of polish grit, then switch to a horsehair brush with very fine polish grit....

A guy I work with polishes punches for dies....the finish is damn near mirror, not chrome but I'm sure it will restore the shine.. I can give you the polish grade numbers if your interested

Those rims are the 99-01 Cobra style. The same exact identical rims were used on 03-04 GT Premiums as an option. They are 17X8 with a 5.5BS. They are NOT reproduced, only new Ford versions are available. And I cant tell from your picture if they are the chromed ones or polished, but they were available chromed, clearcoated polished, and painted Silver from the factory. Depending how bad the lips are scraped, possibly they could be repaired. Not that it would be cheap

CJ Pony and many others sell those wheels new

I have the exact rims and had the tire shop measured them with a caliper which came in at 9 inch so I went with 275/45/17 on the back at it looks good. Yes they are polished

they are 8'' wide rims. You dont measure a rim by going from edge to edge. You measure just inside the lip on each side. same exact concept with diameter

275's will fit okay but buldge out a little and are a better fit on 9'' wide rims.

255's are a pretty good fit on the 8''s

good thing you rely on the tire shop to measure it correctly :) I also went with the 275 to keep the same revs of 811. Live and learn.

I was being sarcastic, meaning you go to a professional thinking they know how to measure a rim and they measure edge to edge and tell me the wrong size.

oh ok lol. yes I'm sorry to say they did. I actually bought a set of "18X8" Boyds aluminum wheels on eBay and sure enough when I got them they were 17X7. And I even asked the person to make sure they were the exact dimensions he told me they were. Heck they even had 17X7 stamped right into them. But he didn't know how to correctly measure a rim, so I ended up getting a backspacing that isnt worth a hell for my Mustang. I've seen it all, one time at a Ford dealership my dad handed the parts manager a diagram of the rear suspension for a Mustang so he could point out the part numbers of the spring insolators. He guy got all huffy and goes to my Dad "YOU KNOW, this is the front suspension, not the rear" I cant remember what my Dad said back to him but the guy basically made a fool of himself and didn't appologize.
