I want to run a 17" rim on my mustang and had some questions. which works better 17x7 or 17x8? could I run a 17x8 with 4.5" bs with a 235/45 and not rub? What setups are you guys using to run 17"s? I dont want to use any spacers. Right now my car is stock suspension with drums all around. If you guys who have 17's on your cars chime in thatd be awesome and pictures are always good! I know this has been talked about many times but I just want to know for sure what works and what doesnt. I already have dodgestangs chart but wanted some feedback from people on here of actual setups they are running.

At the time I was going to put on 17's, I went to the photo part of the website and took a look at everyone's rides who had 17's. I just PM them and receive lots of feedback from them on what BS they had and what they used in wheel size. My BS was 4.5 but sincw you want to run the 17x7, I think 4.25 might be better. I was going to do 17x8 all around, but made that mistake. I was told 17x7 for the front was best, and 17x8 would be the max for rear. You'd probably end up having to fender roll all around as well. As for tires, I was going to do 245/40 in the rear, and front were 225/40 I believe. Can't remember but sounds like the size tires I had.

When I first read the BS.... Well you know what I was thinking.
As for running 17's on a 65 Mustang, IMO they are just too big for that body style. Don't get me wrong I'm all for bigger rims & tires, but the biggest I would go on a 65-66 is 16". They just seem like a more natural fit.
And yes the key is the front UBJ and with the 16's you should be fine with clearance.

I completely understand jspagna1's viewpoint on wheel size. Some people are just going crazy. The proportions of the car are thrown out of whack with 20 inch.

That said, I think my comfort zone is a little bigger than his. I run 17x7 (4.5 bs) on front with a 225/45 and 17x8 (4.5 bs) with a 235/45 out back. I have a slight rub out back in hard right turns. My car is in the shop right now getting new quarter panels and I told my body man to see if you could get me a little more room in the wheel well.

I have had no problems up front.

i have 18's all the way around on my car with slight rubbing in the rear and front. i would run 17x7's up front with 225 40 or 45 series tires. in the rear you should be ok with 17x8's running a 245 40 or 45 series. 4.25 bs up front 4.5 in the rear. if youre in the process of doing body work still i would def roll all your fender lips, something i wish i did for sure. hope this helps.

I put 17 x8 4.75'' backspace 235/45/17 all around on a 1965 stock suspension and nothing rubs, front fender is rolled though I don't think it is needed. If you use 4.5 inch backspace use a 225 tire instead of 235, if you want stagger you cAn use 17x7 and 17x8 215 tire front 235 rear.

first off thanks everyone, this is exaclty the info I was needing.

Now another question, if I run 17x7 or 17x8 am I able to lower the car any if I decide to down the road? or am i going to have to roll fenders alot or what. Anyone running 17's with a lowered car? if so, what problems did you encounter and how much lowered?

thanks again,
Dan

I have 17x8 with 4.5" back spacing and am running 235/40's. Had to roll my fenders because of the rubbing but haven't had any issues since.

Most lowered mustangs roll the fender lips, but if you want to lower it and are against lip rolling I would say 17x7 front 205/45 or/50 tire and 17x8 back 225/45 tire guarantee no rub, 215 front 235 back probably wouldn't rub but it could. Rolling fender lips you can lower and use up to a 245 tire front and 255 tire back with 17x8s 4.75 inch backspace. The backspace determines how wide of a tire you can fit without rubbing the fender lip, best sizes are 17x7 4.25 inches and 17x8 4.75. 17x7 with 4 inch and 17x8 with 4 1/2 inch works but you have to use skinnier tires.

I am running 17x7's on the front with 225/45 Dunlop Direzza Star Specs and a 1" 620 drop with no rub. On the rear I have 17x8's (4.81" BS) with 245/45 matching tires, a 5 leaf mid eye 1" drop and also no rub. I think I could have gone with a 255/40 or 45 on the rear but it would be tight.

The attached picture was taken on the very first drive after restoration. The suspension has since settled a bit. I am very happy with the results and the final stance of the car.

Good luck.

John

JPM1221- thats exactly what I want to do! what was the backspacing on your rims? is it the same front and back? you said "(4.81" bs)" but that was when you were refering to the rear wheels and i was unsure if it was the same for the front as well?
