Please assist me with any info and knowledge that you might have in regards to the maximum tire size that can be placed under a 1968 Super Stock Dodge Dart Hemi clone that has been mini tubbed and also had its leaf springs relocated inboard.

I am trying to determine the largest width and height of drag slicks that can be fit under my dart. Listed below is what I have done so far, and the size of the rear wheels that I have.



This is what I have done thus far to my stock 1968 Dodge Dart 270 that I am converting into a Super Stock.

I obtained a rear wheel well template that was traced from an actual 1968 Dodge Dart Hemi S/S. I then placed it onto my stock 1968 Dodge Dart and cut the wheel openings.

I moved my stock wheel wells inboard to gain a larger tire. This tech article located on this site is very helpful ( http://www.bigblockdart.com/techpages/wells.shtml ).

I moved my leaf springs inboard to gain a larger tire. I purchased a leaf-spring relocation kit from Mancini Racing ( http://www.manciniracing.com/manciniabody.html ). This tech article located on this site is very helpful ( http://www.bigblockdart.com/techpages/springs.shtml ).

I purchased two brand S/S new leaf springs from Mancini Racing ( http://www.manciniracing.com/mansupstocsp1.html ).

I purchased two vintage 15''X12'' Cragar Super Trick wheels from a local speed shop that have a 4'' back spacing.

I have an 8 3/4 axle housing that I am going to shorten to accommodate for the rim/tire combo.

My two main concerns are, I do not want the rear of the Dart to sit up extremely high like a monster truck, and nor do I want the tires to stick out and look like the car came from south of Texas....

Thanks for the assistance!

Depends on how far you want it to stick out past the quarter.

13.1 section width fits Inside a factory quarter with the inboard kit and that is tight. I'd say you can add an extra 1.5" to that and be even with the outside of the quarter.
