tire rubbing issues due to inadequate back spacing.
« on: January 22, 2008 - 08:19:12 AM »
I have a set of ARacing alloys that are 15 x 8 with only 3.5" of back space. I was planning on running 235/60/15 front, 255/60/15 rear but to be on the safe side, what would you say to me looking at or for some 55 series tires? Say 235/55/15 and 255/55/15 versus the 60 series? I believe the 55 is shorter, so I thought  that would help out with any rubbing issues?

UPDATE: After consulting with other members, it appears that 215/60 front and 245/60 rears will suit me just fine.

Since you are only using 255 tires, you might luck out with the 55 series tires, but with 15" wheels I'm not sure if you will like the look of the smaller tire.  Unfortunately what you really need is the 4.5" backspace.  With that I believe you could easily go up to 275/60's.  I had a shot at a free set of AR TT's, but could not use them because of the 3.5" BS (I will be using 275/50/15's).

There still won't be much in it. I doubt it will fix it and if it doesn't rub it's still not a lot of room, especially allowing room for normal road driving. Instead of buying tires, I'd buy some wheels with the correct BS.

 :iagree:  Your problem is unused backspace with those 3.5BS wheels. Unfortunately it's impossible to add backspace. Best to sell and recoup your money and buy the correct BS wheels. 5.5 BS is going to make your life much easier and provide correct clearance on fender and springs.

Find out what cars are running that narrow 3.5 BS and bolt circle and you will know your target audience. Maybe older mustang? You shouldnt have any problem selling them.

Sorry, but that 'Cuda needs better wheels that what you have chosen there.  Just not appropriate for a vintage musclecar.

These AR wheels came with the car- and only  3.5" of back space. I was thinking of using them with smaller tires (215/245) but have been considering something else. I would prefer alloys on this car, anyone got some ideas? I'd love to find some wheels with tires already mounted.

 :iagree:  I agree with IMNCARN82.  Look around on craigslist or something like that.  For the price of a couple of new tires you can probably find a nice used set of tires/rims.  I got a set of Keyston Klassics with nice tires for $250 off craigslist.

Check these out, Keystone Raider wheels.  I think they are like Cragar S/S style.  Check the bolt pattern and backspace!!!!  In Tallahasse.

thanks, I have responded to the Keystone wheels for sale in tallahassee. He mentions they are for a truck, I wonder if the back spacing would be 4.5" or close?

If you can trust him, ask him to measure the back spacing so you can get a round about idea.  Then if they look about right, go there and measure for yourself. 

I just noticed there isn't price listed.  How much does he want?

I think these Keystone are hard to find.  Do a Google search, you won't see much info.  I don't know if they were made a long time ago or what, but keep this in mind incase you bend a rim or have to replace on, etc....

You can get Keystone classics new. Cragar bought them out and is still producing them. Jegs and Summit both have them.

Lotsa wheels out there cheap if you dig. Craigslist of a great place to start and since it is free, tends to have more lower priced stuff than Ebay. Search classifieds here and on moparts and mopowerstyle for some more options.

Supposedly the wheel on the right is a Keystone Raider wheel?  It's a little different than a Cragar S/S. Looks like it bulges out a wee bit.  :dunno:

....and the hub is pentagon shaped rather than round like the Crager. More like a pentastar!  :2thumbs:

Another idea? Re: tire rubbing issues due to inadequate back spacing.

What do the member say about the 17x8 Mustang Bullet wheels (like from the Movie Bullet) THey look similar to Cragars. I kind of like them but dont know the back spacing. Would anyone know what 2005 Mustang wheels have?
