72MachOne99GT

Okay, in effort to be more unique, and to save money, as well as look more old muscle car-like, i am looking for a set up that involves 15" wheels on my 99GT, at stock height, (where it is likely to stay)

Does ANYONE have a similar set up to this? I am hoping for either someone who has this already, or knows enough about old tire ratings and sizes.. namely 15x7/8/10/12.

I want to know what they would compare to with modern numbers, ie: 275 & 315's
( i was already told to go with a 26" tire to prevent from needing to recal the speedo)

here is what im looking at
Back:

Cragar 08/61 Series S/S Wheel
Size: 15' x 10'
Bolt Circle: 5 x 4-1/2'
Rear Spacing: 4-1/4'
OR
Cragar 08/61 Series S/S Wheel
Size: 15' x 12'
Bolt Circle: 5 x 4-1/2'
Rear Spacing: 4-1/2'

Front:

Cragar 08/61 Series S/S Wheel
Size: 15' x 7'
Bolt Circle: 5 x 4-1/2'
Rear Spacing: 4-1/8'
OR
Cragar 08/61 Series S/S Wheel
Size: 15' x 8'
Bolt Circle: 5 x 4-1/2'
Rear Spacing: 4-1/4'

heres what it looks like

IMO it will look terrible but if you like it thats all that matters. You might also want to double check that the rim will clear the brake caliper, there is a good chance it will hit.

I like the way that the fat tire looks on newer (and older cars)

like the pic of code03's wifes car... the fatter tire on a normal looking mustang

but back on course,, did you mean that the wheel, since only a 15" , 'could' have trouble clearing the caliper, as in it woudl rub the inside of the rim?

i thnk thats what you mean is it not?
thanks

I think it will look great, and may do something similar. I've been thinking the old slot style aluminums, Torque Thrust II's or Cragar SS/SS II's with RWL BF Radial T/A's...

Look in the 4.6L forum at code3Gt's 2 cars...

Oh, and yes, you definately need to make sure they will clear your brakes...

only 15s? 15s are tiny

JD1969

Yes that is what I meant. I like a 15 inch on a car with slicks and skinnys, but to each his own.

they arent tiny, stock are 17...lol... well, it depends on your definition suppose

15's are what came on everything old.. which is what i like

I already pm'd back and forth a bunch with code03gt, and i dont think he said anything about having trouble clearing the breaks and such. I might ask him if he doesnt pop in here on his own

so jd, assuming that all fits around the breaks and all,, is there any way other than going out and measuring my current tires, to be able to tell how big of tires i woudl need for each size of rim, wheter i go 7 or 8 in front, and 10 or 12 in back?

i got 15's on mine...

Real easy. Just sit down with your calculator and figure the stock size, and each tire you're thinking about...

245/45/17 is stock... 245 is the tread width in mm, 45 is the sidewall height as a percentage of the tread width, and 17 is the wheel diameter in inches... so, to figure overall outer diameter of the stockers, it would just be...

245mm*.45*2 (=220.5mm) + 17"*25.4 (=431.8mm) = 652.3mm so, just find a tire with a close OD...

I would go with the Torque thrust 2 with some BFGoodrich radial T/A with the white letters facing out, for the muscle car look. I think it could look cool. What really sets that look off is lowering it 1.5"-2". Good luck and let us see the pics. At least your not a sheep!
