tires for 1969 dart

Biggest I could fit was 245 60 15 and they came super close to the fender lip and the springs (wheels 15 x 7 4.25 bs) , so I put on 235 60 15 , did not want to roll the fender , body is so perfect did not want to mess with it .
Wish I could fit the big tires some of you have on your cars , could use the traction
