Has anybody put drag radials on the stock rims? I have been looking and the best/closest I can find to the stock tires(225/45/18) are the BF Goodrich drag radials, but they are 245/40/18. That means they'll be an inch to an inch and a half wider. They should be the same height, but I'm worried about the turning radius of the wheels with them. Any input would be great.

 

If your going to use them for the drags why worry about turning? just kidding I haven't got a clue.

 

I would tend to want to use smaller wheels like a 15 or 16. The 18 isn't much of a sidewall for a drag launch. Also, BFG's tend to run wide across the board.

 

They measure out at 2 cm wider,about 1/2 an inch, and still the same overall diameter. I would run them, but I do not need them for a couple months when snow melts. Would make a big difference at the track. The best would be go to a smaller wheel to keep the rotating mass down and a taller side wall to aid in flexing, it would help your overall ET's.

 

I agree, I would rather put some Weld Draglites on the car and run them, but with the Brembos I can't quite do that. Until I figure out a 17" rim that will fit over them, I am stuck with the 18s.

 

Another thing to consider is the rather small clearance between the tire tread and the strut. A DR with 18 or so Lbs pressure is going to have a lot of tread ripple and will encircle an area larger than the static diameter of the tire. (I learned this the hard way with my snow tires.) You could make a very good case for a smaller overall diameter. Improved safety and cheaper than changing gears in the diff.

 

get WHyperV6 he did a winter wheel change for those who live in the snow proned areas...We don't get that crap here in H-Town thank goodness...

 

You should be fine man. Mickey Thompson also makes a drag radial this size.

 

Here's a thread by another member wanting drag radials...not sure if the Brembo clearance question has ever been answered with this 17" steelie or not?
