I recently found a pair of polished Super Tricks in 15 x 10". I'm planning to put 29.5 x 9 x 15" MT Bias Ply Slicks on them. My question is... What will the overall width of the tire be like moving from a 10" wheel to an 8" wheel. With the 8", the tire has a pretty good bulge in the sidewall. The new wheels are .250" away from perfect size. Wanted 5.5" back spacing, but these are only 5". Concerned with rubbing the fender lip. These are going on a '69 Road Runner with a stock 8 3/4" rear. Thanks in advance.
 
That tire “9” tire reqires a 8” rim. I would not put that tire on a 10” rim. IMHO
 
Most stock eliminator car run a 10" rim with 9" tires with no issue. The usual rule of thumb is section width gains 1/2" (1/4" per side) per 1" of wheel width increase.

Here's mine 15x10 with 4.5 B's with 29.5-10.5w on a 67 Plymouth B-body

Doug, Interesting, and why I asked... I thought the bulge would decrease (stretch the tire more), and allow it to fit. Not looking to move springs or anything. LOVE the silver '67! May have to see if the 10.5W will fit. Are they ET Streets?
 
You should be fine. I had 325/50-15s on 15x10 with a 5 BS. they cleared everything ok. Tight but if I remember right had .5-.75 clearance on the fender lip. (69 RR)

That is per M/T. I was thinking of using 12" for my 10.5Wx31. A friend measured his on 12" vs mine on 10". His were 7/8" wider on the 12". Though I haven't measured after installing tubes the side wall appears to be narrower.

I believe so I'll check when I get home
 
If you change your mind about the 10" Super Tricks. Let me know what your price would be. I'm interested.
 
The tire will surely be wider in overall width with a 10" rim compared to an 8" rim. Probably about 1/2".
 
FWIW the 315/35/17s I am using on a 9" wide wheel call for a 10" width, but I don't have any noticeable sidewall bulge from the 1" squeeze. 5" backspacing, perfect fit in the rear quarters, like it should have come from the factory that way.
