I have a quick question, I was looking into some MT Drags, but I'll need a 15 inch rim. Would it be a good idea to get a wider rim then say a stock 15 inch stock mustang rim?

 

great thread.

 

I would say, yes.

I see many run a 9" wheel and would put allow some additional contact patch. You can go wider, say a 10" wheel, but don't know much about M/T's or DR's in general. There may be some clearance issues with bulging sidewalls that are soft, so would do some poking around to those that are into the 1/4 mile.

PS. Thanks, Kingnut!

 

Know an easy way to find out an unknown rim width, my friend's car has 15 inch aftermarket wheels that are on 215/60/15's at the moment and he wants to figure out his rim width so he can maybe go with a wider tire when he has to get some soon.

 

No exact science here, but generally tell by looking at thow the tire "fits" the wheel. If he has a 215/60 tire, I would expect this to be a 7" wheel with the tire appprox. 1/4~1/2" wider than the outside edge.

Great thread!! But still in a little rut have had Nitto555r's on my 02 gt mustang since I have had it, Love the look and and performance(when they are new). But looking to go with something with a little more grip. Has anyone had much luck with the NT05R, Bfgoodwrench g-Force T/A KDW 2, Bridgestone Potenza RE-01R, Dunlop Direzza Sport Z1 Star Spec, or any other tire these are just a few I have looked at any help would be appreciated.

 

Hey there Jazzer The Cat,

I've seen mention of Mustang owners with 10" wheels running tire widths ranging from 275 to 305...

Quick Question: What tire width would keep the tire's side wall extending straight down from the wheel?

Interesting to note that the Ford Racing data sheet for the FR500C specifies Hoosier 275/35/18's. Not quite as wide as I'd imagine. But then again these are racing tires which when combined with the 500C's overall suspension set-up, may intentionally be slightly narrow...?

 

If mounted on a 10" wheel, a 275/35 is a nice fit to achieve a pretty much vertical sidewall. I happen to like a 265 on a 9" wheel, but a 275 is really rated to fit one. They just tend to be sloppy in the corners due to excessive sidewall, so hence the 265 recommendation. If one were more serious corner-carver, I would say a 255 or even a 245 for very aggressive AX set-up.

For an 8" wheel, a 235 is probably going to be pretty close to straight on sidwalls, but different manufacturers will vary.

Thanks for the clarification on tire fitment for 10" wheels.

Regarding 275's v. 265's on a 9" wheel: Are the tires in this case 275/35/18's v. 265/30/18's?

Thanks again!

 

I have never seen a 265/30 nor a 275/30, for that matter, so would be a 35 series in an 18" wheel.

On a side note, a higher profile tire will tend to bulge a bit more so will not be flush with the wheel profile and "appear" to be wider. This width does not add any contact patch and will reduce the turn-in response, so I have always preferred a lower profile tire. I run a 30 series all around currently and would go lower if a size was available.
