Looking to replace my m/t 325/50/15 drags radials with possibly 315/60/15 drag radials and wondering if I will have any clearance issues under my 68 b-body and how such a tall tire will effect my track time with a 354 rear gear? My best time with the 325`s is 11.82@119mph any ideas on what the taller tire will do? And also thinking about a set of hoosier drag radials and looking for some feedback on them vs the m/t`s. I do use them for street driving so some consideration for that must be taken in as the m/t`s have gone about 2500+ miles. Any input would be appreciated.

The 295-65 will fit better and is 30" tall. I think the 315-60 will be a VERY tight fit.
The M/T will last a lot longer than the Hoosier, so I am told.

I wouldn't run a radial in a stick shift car at the drag strip, my expereince is that once the M/T ET Street Radials break loose they don't recover, at least on my car they don't, I have to peddle it or shift it  I have not tried those tires on a stick shift car so I'm not saying that based off of actual expereinces with them on a stick shift car  Have you used them on your car yet? I would buy a set of stick shift 9x30 slicks and have them mounted on another set of rims for track use only  I have both the M/T ET Streets and M/T ET Street Radials mounted for my car, I use the radials at the good tracks and the bias plys on the street or at marginal or bad tracks, like Friday night test and tune races

No prob. I doubt you'll be able to fit the 315-60 unless you have minitubs and/or inboard spring kit. The 295-65 is a 30x10 tire and is what I run on my cuda. Hoosiers are a softer compound and wear much faster than the M/T. I've never had a pair of them myself, but did a lot of asking around about them recently. The Hoosier is more race only, the M/T more street/strip. Just put on a new pair of M/T's on Monday.

Chip is correct,
I have mini tubs & relocated the springs on my 70 Challenger to fit 315's.
After thinking about it the 315/60 tires will not fit without some extra work. The 295-65 seem like the ticket for a sticky street tire and the extra height will help with all the highway driving I do. Plus it seem to be the taller tire will help a bit getting it down the track when I get it out to play.

E bodys and B bodys are not the same on many things, especailly tire clearances Trust me on that I have owned and raced both. Measure your section width inside your wheel wells(both sides )and subtract 1/2 inch per side and go from there on which tire size to use I have ran both sizes(315x60x15 and 295x65x15) on my Duster, I have a used set of the MT ET Street Radials 295x65x15 that are almost worn out that I could bring to MATS if that would help you see how they fit Let me know if you have any way of getting them to you from thier
