    I have bfg 235/60R-15 drag radials on my dart, but I moved the springs in 3/4". It is possible that they would fit with the springs in the stock location, but it would be tight on the spring side.

    DJVCuda, do you have a photo of those tires and rims. I have 225 - 60 x 14" BFG's on 6" rims right now, but wanted to go to the 245 - 60 x 14". The one thing that had me worried was how much sidewall bulge I'd have with those tires on a 6" rim. Thanks.

    i had pix on here a while back.. there on my home computer for sure..i'll post them tonight when I get home

    the back of the tire does rub the springs under hard corners, but I have had those tires on the car for 12 years and it just shines them... 0/

    Thanks for the reply. Shine is fine, but scuff is rough.

    Re: Biggest rear tires on a 66 BCuda

    With all the help I've gotten from this board, tha one single thing I keep running into is when someone asks about the biggest tire size they can get under a stock, unmodified early A body. It seems that it never fails someone will respond with "Mine is minutubbed and..." or " I moved the springs and... or I radiused the wheelwells and the tires stick out like a ricer, but...

    Just kidding on that last one, folks LOL

    But really What is the largest practical size on a stock spring location, non tubbed (Mini or MAXI), non radused, rear wheelwell on a '64ragtop Dart Now how about the front

    Thanks a bunch. folks, and no offense meant to anyone!

    Hi Fstfish66,

    I am currently building a 66 Barracuda just like yours and I wanted to know how you welded your 4 link or ladder bar clip to the rear of your car? Do you have any pictures you could send me?

    I asked a few years ago and your correct, meats mean spring relocation or tubs. I tried a set of 275/60R15 for giggles (had a set of custom 5 on 4 15 rallys at the time) and they hit, but even some smaller ones ran into a snag. I couldnt even get them on without taking the shock off so the rear would fall down enough to fit the tire up in there. I think 245's are about it on a STOCK rear/spring/fender/rim combo and that encroaches on the safety margin of the rim width. Tires are so much better today traction wise. sticky street/drag radials are better than the old M&H Dragmaster slicks your dad ran. only the guys who run some wide tires now can tell you for sure.
