Wheel/Tire Dillemma
I had a flat tire on my 1988 Custom Cruiser. It is a 245/60/15. I could not find one anywhere, I finally had to have Tire Discounters order one. This tire cost $170.
The other front tire is the same size, but with minimal tread.
The back driver is 255/75/15 and back passenger is `235/70/15.
I've already bought the one for the front, so I might as well get it a matching front tire. But I need to know if i should just get new rims altogether for the back. I don't need these stupid expensive aftermarket sizes on my wagon.
When I bought it, it was lowered about two inches. the dumbasses cut the springs, so I don't know if it has anything to do with the size of the tire they put on there.
I don't even know what size is supposed to be on there.
what would YOU do

If I remember right, original tires were 225-75-15.
So according to tirerack's conversion chart, a 235-70 or a 255-60 could be used also. I am guessing a 245-65 would be int here, IF such an animal was made.
I would replace the springs to stock, unless you want it lowered. However, make sure that your camber is correct though to keep a good look and tires wearing evenly.
Many times, cutting that much off the spring will cause camber adjustments to be maxxed out.

If it was me, I'd buy new springs and install them. I'd also put on matching rubber front/back to suit my needs. What kind of moron puts 235 /70 on one side and 255 / 75 on the other? That car would have leaned a little funny right off the line

I can see it now. In 5 years, one would have 12" wheels on the left, 24's on the right.
Good choice. Maybe that fire-breathing 307 will quit smoking them up so fast...

Just an afterthought. If the guy chopped the springs and got them wrong maybe he was trying to make up for ride height by compensating with tire sizes. Another good reason to change the springs.
Wouldn't odd size tire combos like that have a negative effect on alignment and suspension?

My 77' 88 coupe originally had G-70-15(about 225/70/15) on 7" wide rims. Later went with 255/60/15 tires on 8.5" rims, and much better. Actually had to grind the the rear wheel house inner lip, for the white letters to clear. If on a buget, couple things you can do about the lowered springs. Moog Cargo Coil rears, and some rubber spacer donuts front would be easiest. Could go air shocks, or spring air bag inserts rear. Might ride pretty stiff with the air options though.
