what is the widest tire/rim combo that anyone has been able to fit into the rear wheelwell of a '69-69 skylark... what backspacing was used? what modifications were made (frame notch, rolled fender lips?) thanks wes :3gears:
Well right know I have a 30x9 hoosier on a 15x8 which is 12" sectional with 4.5 back spacing tomorrow I'm trying to put on 29.5x 10.5 Mickey Thompson which is 30" tall i'm going to try it on the 8" rim to see how much room is left if any to see I want to get a 10" rim with a 5.5 back spacing going by the chart the sectional of that tire is 13.1 on a 10" rim so i'll give you an update on how I make out and some pictures of how much cutting I'll have to do ou:
how much cutting have you done so far?.. and yes, detailed pictures would be MUCH appreciated... you could post them for everyone and/or email me at bilgerat671@gmail.com thanks, wes
Had a 12 tire on a 10 centerline in a 68. Had to cut fender lip until it fit. No tubbing or frame notch. The car was also lowerd alot. The car also had a 10 bolt rear so i think that also helped.
you remember what the backspacing was & what the crosssection of the tire was? diameter of the tire.... all the rim specs (dia, width, B/s)? pictures? how much narrower is the 10 bolt or how is it different from the 12 bolt for it to "help"? thanks, wes
Wes my brother and I are running a 15X8 with 4.5" BS on his 69. It has a 12 bolt and I would say that a 5" BS would have been ideal for proper clearence. The 4.5" works but it is still tight on the outside.
I dont know the what the specs were. It was 10 years or better. The 10 bolt is narrower. Its not that hard to measure your setup. Its a good idea to check your car because its not uncomman for the body to be off center. I have pics but they are not that good.
I have a 64-67 width housing which is slightly narrower than the 68-72 housing and use a 5.5 inch backspace 10 inch wheel this is about max with a 30x9 slick the goodyears seem to be a little more narrow in their section width than the Hoosier and MT. I now run a 30 x10.5 Hoosier radial but I had to cut and section the frame a half inch to make them clear,I also can now fit a 295/65/15 MT drag radial. Hope that helps good luck. :3gears:
We ran a 30x9 radial slick on that car. I wanna say when we first bought the car it had a 28x10 or maybe even a 28x10.5 (can't remember honestly). It rubbed a lot even w lip trimming. Especially during turns with the spool. That's when we went 30x9.
