Planing to get new wheels & tires for my 2005 V6 and really like the look of the bullitts. I'm currently undecided between 18" and 20" (not only cost-wise).

Any recommendations? Will the change from the stock 16's to a larger wheel / tire combo affect the speedometer significantly? Will the 20's cause any problems on the V6 (rubbing, etc.) (Sorry, but I'm a total aftermarket-tire-noob)...

Left: 18's Right: 20's

 

Increased wheel diameter + decreased tire sidewall = factory outside diameter ~ 27"

Check tire size calculator on any website (google it).

Bite the Bullitt and go with 18" Polish Aluminum!

 

...for the tip... The tire size calculator I found said that 265/35-18 shouldn't affect the speedo at all...

 

20s! I loved mine when I had them on (off for winter). You can see em in the background in the pic.

 

Those are the ones I'm looking for... Where did you get them, American Muscle (formerly Mustang Tuning) ?

 

Yep sure did. Best price I could find.

 

Those look so good.

 

Or you could always go 18s:

It a toughie, I am trying to decide for myself. I like the meatyness of the tires on the 18's, but the 20's seem to fit the car so well!

 

i like 20's...

 

Well, besides making your unsprung weight horrible and putting a lot of strain on your poor V6 engine to push those heavy 20's around. Should look cool.

 

I would go with the 18's.

 

I vote for the 18's. I have 18x10 (rear) 18x9 (front).

 

Not a fan of anything bigger than 18's.

 

I used to have the 17's on my car (stock pirelli tires mounted on chrome bullitts from 99-04). Right after I got my Roush Bumper I started having problems with the bumper scraping on driveways (the Roush Bumper is about an inch closer to the ground then the stock bumper).
Called the shop that sold me the bumper and they suggested 20's, but once I started looking at that size wheel and tire I decided I didn't like the look so I went with 18's and I'm real happy with the choice I made.

 

18's ...................

 

Really depends on the look your going for. For example 18s on my car would look extremely wierd, the 20s looked right at home. I just wouldn't do blingy 20s, maybe some anthracite bullitts or black bullitts or something with color. If you want to fill up the huge wheel wells go with 20s, if you want that old hotrod look a set of 18s is gonna be your best bet since you can do the huge tire look.

 

Not to hi-jack but, I love the look. Plans to lower it I hope?

 

That's exactly what I was going to do, fill up those huge wheel wells... The standard 16 just look too tiny in there... (that's the same diameter I used to have on my Mini Cooper...)

 

My opinion: Go with the 18", 20" is to big. The mustang is classic american muscle, which was about more tire, less bling. Nascar still uses 15" wheels.
