What size tire?

in the rear u can go 275/60r15 and the fron i suggest u stay with a 15 and just use a 225/60r15. thats what i used on my car not too long ago. maybe u should try that.

i run 275/60/r 15s on the back.. i fun 205/50/r 15s on the front... i plan on going eventually to pizza cutters on the front.. maybe 175s

I have a '66 coupe and I'm getting new tires and wheels for it soon. I was just wondering what size I should get. I know their is a chart, but I can't go to it for some reason, so don't show it to me. I want to get the biggest possible tire on the back without rub and I don't really know about the front. I want to go with a "drag racey" look. I was thinking maybe a 15x8 size wheel in the back and a 14x7 in front. also, what size backspacing will I need?

These are the wheels I might get because they are cheap and I like the style. are these alright?

Thanks

Why can't you pull up my chart? What is the problem?

To answer your question, you WILL not get 275 on the rear of your car without them rubbing unless you do something terrible like add air shocks which is highly discouraged.

On a 15x8 rim with 4.5 backspacing you can fit a 235 60 15 without rubbing.
There is a chance 245 60 15 will fit without rubbing but suspension age, and setup, and manufacturing tolerances have a lot of affect on this region.

In the front you can run a 205 65 15 for a skinny look to get that drag race look. You can also considering a 205 60 15 for a shorter tire up front to accentuate a raked look.

whatever you do, get 15's up front and out back... No sense in buying 2 differnt size tires and nonsense. You wont really be able to see teh difference in the 2 wheels anyways.

If you want a real race look, get some draglights.. 15x8 out back and 15x3 up front

I'm not sure. Whenever I try to open it, I get an error and it closes.

Thanks for the replies. And do those wheels I have a link for seem good?

All those outlaws II look to have 3.75 BS...on a 15x8 rim that will hold the wheel out too far to fit the widest tire in the rear.

Nick - I was looking last night at how much room I had back there. It appears that 245's would fit no problem with the TTII's (4.5 BS). There is at least an inch between the tire and anything else.

What are you running (width wise) on yours? With all that power you're putting out 235's would seem to be awful narrow!

I'm actually considering getting new wheels with less BS to pull the tire away from the frame.

I know.. that 245s are no problem.. but if you are making good power.. you can get 275's with minor mods.. roll the inner and outer fender lips.. air shocks are a plus.. only if you plan on running 60's.. u also could use shackles if you want a nice raked effect..(mine is a drastic rake)
Look at http://forums.stangnet.com/showthread.php?t=425564

oh yeah no offense but i dont like those rims.. They were on the car when I first bought it.. I didnt like them at all. they bent really easy... but opinions are like butts everyone has one and some stink...

I run a 255 40 17 on a 17x8 wheel with 4.75 bs with rolled rear fenders and lowering springs. I also have rear disc brakes or else I would be running a 265 40 17 rear tire. The disc brakes change my track width slightly. The original question asked what would go on with no problems and no mods I know 90% of the time 245 go right on the rear with the correct back spacing, but there is a lot of variance between mustangs so I like to make sure I preface my answers as such.

With no offense to others on this board I have yet to see a 65-6 mustang with 275 rear tires that were actually under the fenders. I have seen 265 40 17 on a 65 on a 17x8 w/ 4.75 bs and a small spacer to keep it off the springs. He also has heavily rolled fenders like mine. As the sidewall size goes up, the overall width of the tire increases as the side walls flex out and bubble. Overall tire size has a lot to with the manufacture specs. 2 265 40 17 tires from different manufactures are completely different sizes with regard to section and overall width.

I know sometimes with the 275 in combination with a stiff stock height suspension or shackels that lift the rear and/or air shocks they fit without rubbing because of how stiff it is or because you have added items that artifically prevent the suspension from going through full range of motion. I will be sure to preface and say it is my opinion that these setups are less than ideal and are a throw back to the late 70s early eighties in styling and function. But because I do not care for there does not mean they will not work for you...and hey..it is your car...don't let the opinion of a faceless poster weigh too heavily..if you like the way the car looks thats all that is important.

AS a FYI too, the problem with airshocks is the shock is bacially supposrting the weight of the car, not the leaf springs. The air shocks bolts into sheet metal under/behind the rear seat and is not designed to hold that kinda weight. As time goes by the stress on the mounting pointing causes metal fatigue in the area and the whole top of the shock has been know to punch through.

One of the reasons I invested the time compiling/creating and continuing to spend time updating the Modyfied Wheel and Tire charts is because of the huge variance between identically equiped mustangs. As my charts have continued to grow you can start to see trends within the data as to what works 100% of the time, 90% of the time, 75% of the time without mods....and then what mods are possible..or from another direction what the widest tire I can fit with this set up is with 100% accuracy, 90% accuracy...etc.

I will heavily qualify Nicks comments about the problems with air shocks. My PO had air shocks installed when I bought the car and the right side shock did in fact punch through the upper mount. I have it temporarily repaired while I prep the replacement shock mount. By the way, did you know that there are about 1/2 of the number of spot welds in that piece as in the cowl cover? What a major PIA!

I would stay away from air shocks at all costs.

Hey 66'Stanger - I am getting ready to order a 15 x 8 inch styled steel wheel from Stockton wheel to put on the rear of my 1965 Mustang Fastback. They make the wheels and will do any custom backspace. I am going to go with around a 4.5" backspace. The tires will be BFG Drags, 235/60/15 which is 26.1 inches tall and 9.5 inches wide. Also, they have many other wheel options there. I would check out the website and call them if you are interested. www.stocktonwheel.com Good luck! -Taylor
