93' cobra wheels, max width tire?

[xplo89gt]

I have 93 cobra wheels. Which I believe are 17x7.5. Looking to get new rear tires and want to put the biggest tires on them. I want maximum contact area, so obviously I'm not going to try to put too big of a tire on there. I have a 245/45/17 on there now, and I'm just wondering if a 255 would work or should I stick with 245?

Also while i'm on the subject of 93 cobra wheels. What can I do to the front so they don't rub when doing a full turn? I'm planning on upgrading front brakes soon, so I would like to consider things that would help it not rub as well as best braking.

I've got 255/45 17's on the back and they fit well, but they do rub if I take a hard corner. just out of curiosity, how did you mount your wheels? Did you use a spacer? My front wheels rub as well, I just sort of ignore it

 

[xplo89gt]

Nope no spacer. I have just been ignoring it. Guess ill just stick with 245's in the rear. Someone told me if you have 93 cobra rotors it wont rub. Not entirely sure.

The 93 cobra spindles stick out further than a regular fox. I have the same issue with rubbing while turning and i use spacers too. Matt90Gt's website might tell you which spindles to run with these wheels.

I have seen people with 275's on them in the rear no problem at all

If you want the full tread to maintain good contact with the road, a good rule of thumb is to have the section width of the tire not any more than 2" wider than the wheel width. 7.5" + 2" = 9.5". 9.5" is 241 mm (25.4 mm/in). The first number in the tire size is the section width. So a 245 is about as wide as you'd want to go with a 7.5" wheel while allowing the tread to remain in full contact.

I had Original 93 cobra wheels on my old '89 gt vert. They rubbed at first and then I got my musatng shop to notch out the lowere a-arm to prevent rubbing at full tilt. It is only a small piece so I'm pretty sure there were no issues of less strength or I'm sure the guy wouldn't have done it.

I would sell your original 93 Cobra wheels and buy 3 sets of Replica's. As already mentioned, the wheels are made for the 93 Cobra, and not any other Fox. The 93 Cobra has a wider track. These wheels will stick in more and cause rubbing problems. www.wheelreplicas.com Jeff is a great guy. Give him a call and get the wheels that look IDENTICAL and will have the CORRECT offset and backspacing for a Fox body Mustang (minus the 93 Cobra). I have a set and they fit like a GLOVE!!

Speaking of Cobra

For yall's consideration...I have 255/45-17's all around on mine and no issues. Pics attached or see my garage

If they are original offset 1993 cobra wheels, just buy 1993 cobra front rotors

They are the same rotors, but with a 0.75" taller hat. It's like running a spacer, but much safer. The rotors will work with stock spindles and calipers

Out back, you should use either a 3/4" spacer, or a thbird rear disk setup which pushes the wheels out 3/4" each side
