Size limits not withstanding, I wonder if the rapid
transitions of solo are more agreeable with overtired
rims, which seem to be a little more forgiving of
sudden brake/steering inputs. Note that E/F/G/H
production cars, which have 6-7" rim limits, all have
cantilevered 9-10" tires on them (the ultimate stiff
sidewall).
I know on my DSM, the 225's did not have much if any
less raw grip than the 245's, but I had to be very
careful not to overdrive the 225s (too much brake/gas
too late) or they would breakaway into a long slow
slide. The 245's let me be about 10-20% more
aggresive (or careless) and just mush briefly then
take a set. This was on Kumho's, not sure about
hoosiers.
