the 30 series is .5" smaller but the 35 series(both in a 305) is .7" taller. So neither is going to be correct.
I just prefer more of a sidewall that’s all. It’s just a bonus that going with the higher profile is cheaper. Also fills out the wheel well more if you are stock suspension.
Louk -- See Dusten's comment above. When I used a wheel tire size calculator the 30 profile tires (in the 20 size at least) were slightly closer to the OEM tire diameter than the 35s and thus creating a bit less speedometer inaccuracy.
db252 -- Beautiful, thanks so much! Do you happen to have any shots looking down the side of the car? I want to get a sense of how much tires, especially the fronts, extend past the wheel well.Not a Bullitt but those sizes you mentioned exactly.
That'll be dependent on wheels.
I'm on JRZ coilovers and lowered about an inch. I have no extension of tire/wheel outside the fender but I’m very close inside with no rubbing. My front offset is 35 and rear is 50 with 10” and 11” wide respectively. I’m also around -1.8 camber on the front for my street setup. I’ll get a specific pic though if you still want.
1.5 vs1.1 off mph at 60. One is reading higher the other lower. Considering that no speedometer is true speed and most have a % that they deem is “in spec” it doesn’t matter but to each there own.
At this point, most likely going with the Carroll Shelby CS-11 "Bullitt" style wheel in Gunmetal. I believe they are 20 x 9.5 for the fronts and 20 x 11 for the rears. They are also suprisingly light weighing about 27.8 and 29 lbs respectively.
when i went to 295/30/20's my speedo was 6.7% off gps verified. Its now less than 1% thanks to forscan
I love those! They are going to be my replacements when the stocks rubber is done.
Yes, the Special Service Duty wheels I believe are made for Steeda's law enforcement/patrol vehicles and look like they only come in black from the factory. i would most likely get them painted something closer to the dark grey of the original '68 Bullitt GT 390 movie car.
