how big a tire can you put on a 62 dart b body?

how big a tire will go on a 62 dodge dart? 28x10 ? what rim back spacing ? how much do you actually gain by moving the springs in? no wheel tubs. probably 62-63-64 pretty much the same .any info would help .thanks

'62 Dart has the biggest opening of any of the early Bs, followed closely by '62 Plymouths. Can't give you a size though. 9x30 on a 7 or 8 rim, 4.5BS seems to just fit in most '63-'65 w/o mods. 11" of sidewall width is the max on my '63-'64 wagons, fairly tight near the springs. Narrowing the rearend to 53" flange/flange helps with 4.5BS; doing that, I can stuff 285/70x15s into a wagon, but it's tight.

I had Hoosier QTP's that were 29 x 11.5 on 8" wheels on my 63 Sport Fury. They fit but they were close enough that they rubbed some on turns so I went to the 30 x 9 Hoosiers on a 7" wheel which fit great and have plenty of room. Ron
