DragCat Posted April 29, 2019 Share Posted April 29, 2019 Ok I thought there was a wheel and tire sticky but I can't find it. My confusion is Back Spacing. What I have, stock 70 running 15 x 7 rally wheels & p225 60 R 15's no trimmed rear quarters stock suspension. I want to get a set of drag radials to stretch my legs at the track. I want to stay with 15 wheels and run a 235 60 R15 drag radial but I don't know what back spacing to get for the wheel. I currently have about and inch and a half clearance between the existing tire and the quarter at the top. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted April 29, 2019 Share Posted April 29, 2019 You can run the rims you have now or if you want dedicated drag radials rims a 15x8 with 4.5 inch backspacing will work fine. Even if you decide you want to fill the wheelwells with a 275/60 r15. 1 Quote Link to comment Share on other sites More sharing options...
714024SPEED Posted April 30, 2019 Share Posted April 30, 2019 I have a 15x8 with 4. 1/2 backspace with a 275 60 15 tire so you should have no problem with a 235. Quote Link to comment Share on other sites More sharing options...
DragCat Posted April 30, 2019 Author Share Posted April 30, 2019 Thanks, yes i'm going to have a set of dedicated wheels and radials for the track. Hate to get caught cruising around town if it rains without the BFG's on the rear. Quote Link to comment Share on other sites More sharing options...

Yea James, thats going to be my direction, 15X8's 4.5BS with drag radials on the rear. Jegs has a we mount and balance too so I don't have to go to a local tire store. My buddy runs drag radials on his corvette and if he gets caught in the rain on the way to or home he says it can get pretty white knuckle driving. I'm pretty light on the gas pedal if it rains even with the BFG's lol Quote Link to comment Share on other sites More sharing options...
420ponies Posted May 16, 2019 Share Posted May 16, 2019 I run A 5" backspacing on mine. as you can see, no issue with tire scrub on wheel well. Jeg's sells a rally with 15"x 5" BS Quote Link to comment Share on other sites More sharing options...
DragCat Posted May 16, 2019 Author Share Posted May 16, 2019 Thanks again, i'm rethinking my 235 thoughts with all the info and pictures. I think Jegs is spying on me because now i'm getting Drag Radial tire sale emails lol Quote Link to comment Share on other sites More sharing options...
