Keep in mind that genuine performance 15" tires (at least ones sized to fit
larger cars) are getting very scarce these days. I don't think the 255-55
size you're thinking of even exists. There used to be some decent 245-50-15
and 265-50-15 tires available, which were a good fit for 15 x 7 and a15 x 8
on a classic. BFG Comp T/A, GY Eagle VR could be had, but now it's mostly
"cruiser" stuff like Radial T/As, or a drag radial tire. Dunlop still has
245-50-15 in the Sport 8000 line, which is a decent tire.
I've been looking at wheel and tire options for my Cougar, and am running
into the same thing. I scrapped the idea of running 18" Marauder wheels,
and am considering lots of other ideas. If you have the budget to up to
16", your choice expands quite a bit. With 16 x 8 all around, you can go
with 245-50-16 at all 4 corners, or a 245-50 / 255-50 staggered combo. Lots
of good stuff available in those sizes. I'd say to stay pretty close with
front and rear tire sizes. Remember that adding grip to the rear (with
larger tires), is going to increase understeer. Great tires will make the
most difference to your car IMO. I'd rather have a car with good tires and
shit suspension, than the other way around.
As far as the suspension goes, Mike covered the basics. It depends on your
budget really. My Cougar has KYB Gas-A-Just shocks, generic 620 lb. front
springs, 1" control arm relocate, and stock rear springs with lowering
blocks. Rear shackle bushings are being replaced this spring. The car is a
decent handler, other than the random worn-out factory power steering. LOL
It currently has 225-60-15 Firehawk SZ50 tires (Firestone's old top line
Z-rated performance model), mounted on 15 x 7 69 Shelby wheels. I was
trying to find a source for re-rimming or replacing the Shelby wheels, to go
up to 16" or 17". But so far, all I can find is 15 x 7 or 15 x 8. I'd
happily go with the 15 x 8, if there was any tire choice left.
