Ok so I have a 66 mustang and am going to be running 17x8 2001-2004 bullitt rims all the way around with a 1" spacer. My question is what tires should I go with? I am not sure about size etc I need for clearance and also for a good look.

a 235 45 17 tire tucks in nicely without problems on alot of these cars. some people go all the way up to a 275, but a 235 generally fits very well if the car is lowered and you want them to tuck

235=the section width
45=the aspect ratio(sidewall height is 45% of the section width)

a 235/45-17 should fit real nice. in fact a 245/45-17 should also fit without problems.

I have 17x8" wheels with 245/45/17s on the rear. The only way people can go wider is by clearancing the rear wheel well or with a shortened rearend.

it really depends on how you want the car to ride, and how well the rear axle is centered in the car. mine came out perfect, but I have heard stories of axles being off by .5" so you really need to check first hand. take a look at the tires that are on it now (probably 215 series width). get under the car and imagine about .5 inches added to each side. that is a 235 tire. Imagine .75 on each side. that is a 245 tire. tell us what kind of clearance you have. I minitubbed my car so I can run up to 275 without crazy issues, but some people already have (iz). I suspect a 275 can't be used and actually tuck the quarter panels

235/45/17's might fit in the front, but you better be willing to roll your wheel well lips and get an alignment with at least 2* negative camber.

I have 225/45/17 front and 245/45/17 rear on 17" X 8", w/ 4.75" backspacing. I could have gotten a 255/45/17 on the rear, but I don't think I could squeeze in a 235/40/17 in the front.

That -2 will certainly make it stick on the turns

I ran 235 45 17 successfully on a 17x8 with -1 for year. I now run 245 40 17 on the front but I do have -2 plus on the camber. I also have never rolled the front fenders
