Here is a tireszize calculator that I found that can be helpful http://www.powerdog.com/tiresize.cgi
Just type in your size and any other sizes to compare.

thanks for the help. according to that calculator, the diam. is .9" smaller. will this give me esp failure?

Even if you're running smaller tires, the computer don't know that. Now, run different sized front and rear and the computer might take notice.

I'm running 245/40/20's in front, and 275/50/20's in back, and I haven't had any problems from the computer.

Did you check the correct bolt pattern for those wheels? Last time I checked, the Coys wheels were offered in a 5X4.5(5X114.3) bolt pattern. I think you need the 5X115 bolt pattern if I remember correctly from reading from these posts. Someone correct me if I'm wrong.

I don't want to rain on your parade but I do want you to get the correct bolt pattern for your wheels so that you wont get any vibration problems.

Good Luck

uh-oh, good question. I spoke directly to the owner's son in Utah. He said that they've already fit over 20 Magnums. So I figured he knew what the correct bolt pattern would be. Guess I'll find out soon enough; I get them Friday!

Thanks for your concern. I'll have to check into it.

They are 5*4.5, not 5*115mm. They'll go on, and it seems some have had problems, and some have not. This is my understanding of reading about the wheels on this and other forums.

That is why I ended up getting the RT wheels for my SXT. I wanted the AR Torq IIs or Coys, but neither had correct bolt pattern. Not sure if any manufacturer has the EXACT/Correct one and most are using the Mustang/universal 114.3 size.

Find PhatJay member here he can hook you up with some hubcentric rings for your Coys. I have Coy C5s and after installing the rings they are vibration free ride!

Tire shop I spoke with said there's not much available (except for custom). But if we wati a bit, the manufacturers will be puttin some wheels out soon.

**Lex** · 07-27-2005, 10:45 PM

diamondrmp, where did you get your Coy's? do you like them?? thanks for the tip on the rings. i'll pm PhatJay in the morning.

the rep I spoke with said he used 4.5" backspacing. does that have anything to do with the bolt pattern?
