AutoX Tires
Since I got the auto cross bug, I would like to have a set of better race tires on my Rally wheels for the race days, I would like to keep the size of 255/60/15 or a bit larger in the rear. Any suggestions about brand and size of course any recommendations are appreciated

The 15 inch tire is never going to perform as well as a 17 or 18 inch tire. That being said there is not much in the way of performance tires for a 15 inch rim. There just is not that much call for a 15 inch tire anymore. Are you looking for a slick racing tire or a good street tire.

about 15" tires - I was recently going to purchase a Michelin "V" - rated tire in 225/60/15 Pilot® Exalto® A/S

Still considering 17's.

For AX'ing, the OP needs as much footprint of soft compound rubber as he can get on the ground. 225's are on the skinny side for 8" wide rims and in a 60 series would only be ~25.6" diameter. The Avons mentioned are probably the best performing road legal tire available today for 15" rims, but 17" or 18" wheels would certainly open up many other choices.

If you want to stay on 15's you're choices are limited, but Hoosier makes the Street TD sports car DOT bias tires in 245/45, 245/60, and 275/60. They're decent tires but are not as fast as Hoosier A6's or Kumho V710's (but no good 15" sizes in those tires). Hoosier also has 15" choices in non-DOT bias (Vintage racing tires) if those interest you. I believe they have some 15" tires on closeout, check their discontinued inventory.

Steel rally wheels are about the heaviest you can get.

I'd suggest setting the rears a few PSI lower than the fronts. You can try chalking your tires at three points around the circumference where the tread meets the sidewall, and adjust your pressure according to the wear on the chalk marks. If there is no wear on the marks, lower the pressure; if there is wear, raise the pressure.

Hoosier also makes the R6 and A6's for a 15" rim. The 245 fit square on a 8" wide rim. Ran them for years. I am currently running the 275-60 on a 15x8 rim. I normally run the R6's Hoosier. I get a little more life out of a set of R6's than A6's.

I currently run 84-87 style 16" wheels on mine because the tire selection in 15" is almost non-existent. I run Kumho Victoracer V700s or Kumho ECSTA V710 in 265/45/16 size. This combo with the adapters is still lighter than the 15X10" wide circle track wheels we used to run.
Hoosier A6 and R6 do have a 275/35/15 that would work on your 15" wheels, but those tires are $266 a piece at Tire Rack. You would also most likely have to trim some of your fender lips to keep from rubbing.
In the near future I am planning on stepping up to 17" wheels because the tire choices are so much greater. I could even end up running a cheaper tire on the 17" than what I do on the 16" wheels. On that note, anybody have a set of 17"X8.5-9.5" wheels for sale really cheap (looking to stay under $250)? Paint condition or curb rash doesn't matter, just that they are straight and will hold air and fit a 5X4.75" bolt pattern.

MT Street ET rims or tires? Both are for drag racing. The tires have a very weak side walls that allow them to wrinkle for drag racing, something you don't want in autocross. The rims may be to weak to handle the side forces also. Most drag racing rims are, just that, only made for drag racing.
