The OEM wheels weigh about 22 lbs, for those of you that wanted to compare. That may not be perfect as it was a "bathroom scale" measurement. Needless to say, that's just the wheel, itself, tire not included.

I remember a Mustang comparo back when the '05 GT and Saleen w/ 325 hp were in the same article. The stock GT was .1 or .2 tenths quicker in the 0-60 times. I thought this was strange! Paying all that money and 25 extra horsies and getting beat in both the 0-60 and 1/4 mile. Well, the Saleen had the 20" rims. The GT had the 17" rims. If you're performance minded and you don't have a blower, the 20's are not for you. If you're all about looks, AND THERE'S NOTHING WRONG WITH THAT, then strap on the 20's and enjoy. I'm somewhere in between the two.

That is lighter than I thought, so my tires must weigh around 28lbs.

Most 20's i've looked at weight around 36lbs so my comparison between having a one piece aluminum is probably pretty close. So if you want 20's and still want to hang with a GT without 20's just get yourself a 1 piece shaft and hope the other guy doesn't have one.

Why are you starting crap with me? Are you that bored, or just that much of an ass? All I know is that I get a lot of thumbs up and compliments. Nobody cares if you think they look out of place. This thead is not about opinions of how they look. I only mentioned getting looks, because that is the only change that I noticed after putting them on. Since you think the car only looks good with a retro look, did you grind your calipers to fit 15" Cragers and white letter tires? If you don't like the way 20s look, start your own thread instead of hijacking one just so you can tell us.

Nitto Tire emailed me today to tell me that their 255/35ZR20 tires weigh 29.5 lbs. I guess the entire wheel/tire package I'm looking at will weigh in at 64.5 lbs. Anyone out there with 18's wanna tell us what your wheel combos weigh? Maybe our engineers can chime back in with HP loss data now.

grabber orange, i have 20-10s and 20-8/5s, 275/35/rears 245/35 fronts my rear rim weight is 28lbs rears and fronts 26lbs. its the tires that make a huge difference, some tires weigh almost 3 to 4lbs more than others!! maybe a 4 to 5hp difference nothing to lose sleep over, plus if you drive primaraly on the street you will never tell the difference(if you have power adders of course) all in all do what makes you feel good

I weighed 235/55/20's on my bathroom scale and got 66.2 lbs. I weighed it three times to make sure I was seeing it right. Its a little heavier than I thought it would be but I should have expected that because the dealership put them on before the car was purchased.


If you get lonny2's front rims and the nitto tires you could have a 55.5lb combo. hmmmmmm maybe I should change.

Your guessing? It doesn't even say how much those weigh. I'm guessing that a 17 inch rim with a tire of 30 diameter or more will result in less rwhp, but probably hook at hell of a lot better than any 245/35/20 will.

This is insane! Anyone with 20's who wants to race?

There are some 20” rim/tire combos that OUT PERFORMS some 17” rim/tire combos in drag racing and that is why I choose to fight this battle!





i am guessing that these:

with 245/35 will allow more rwhp than 17x9.5 chrome spinners with 295/50


I wish you lived in Texas, I'm actually curious to see if my new 295's (20's though) slowed me down or sped me up (in terms on hooking/times, not dyno numbers). 295s vs 235 but 18" vs 20".

well dotsonian if you read mmff they weighed stock 18' with 255 45's and that combo weighed 55 lbs, the stock wheels no matter what size have some weight to them. factory makes them heavy and strong! now let me see v6 , chrome wheels, bathroom scale,,,,, hmmmmmm buy the way i used a ups scale to weigh my wheels.

I have 17's and i'm willing to bet those tires will slow you down.

Well, lonny2
Just so you know, my hmmmmm was intended to be shown as a pause for self thought, not sarcasm. My reference to your front rims was that if a person wanted light rims they could use the kind you have and end up with a 20 inch tire wheel combo that would have no increase in weight from the stock configuration. Your rims are a good example of 20's, mine on the other hand are a not good for performance.

I am happy with what I have and probably would change to lighter rims but I feel that I would upset the person that gave me the car as a birthday gift. I definately do not want to do that.

BTW, my bathroom scale is certified for medical use and regularly checked for accuracy. Just as the ones at most medical clinics are.

i ran 13.56 @ 101.78 yesterday with 20s, a system, full tank, spare tire, and a 30mph headwind. i cant say that the 20s themselves hurt me too much there.

20's Hurt you performance because:
1. There is less sidewall to actually bend during launches so that the tire doesn't put all the power in one woop to the ground but a more progressive (Look at a dragster wheel, the rim turns almost 1/2 way before the tire starts moving)
2. Most 20's are made for looks and not performance thus they tend to weight more which this in turn means more rotational weight and approx 1lb rotational = 4lb regular weight
3. Since they have less sidewall and tend to weight more and have a bigger radius that means the weight is more concentrated farther from the center of the wheel which this in turns makes it harder to turn.

I am trying to get a friend of mine to our local dyno to prove the actual hp loss on stock 17's vs 20's. Of course I am gonna weight his 20's so you guys get an idea of the 20's weight.

I agree with some of what you are saying about weight and sidewall flex but the radius on the tires will remain the same. Thats why you have a small sidewall. I think the weight thing plays an important roll in performance and the fact the 20" combo does weigh much more than 17's or 18's does rob power but so does a full tank of fuel and passengers. Just have to pick your battles.
