yes, but they will be quite a bit smaller as they are 4 sizes smaller.
Yes, that is a pretty good substitute.
My 95 GC LTD needed new tires, shocks and wheels (the oe wheels were oxidized to the point that the bead wouldn't seal). So.... 15 inch American Racing chrome wheels, new shocks and a set of BF Goodrich AT/ta tires in size 2357515. I tried to go to a 30X950 tire but they rubbed even with the shock update. I believe that, unless you lift several inches from the stock suspension, 2357515 tires are the largest you can go. And the BF Goodrich tires are really nice looking and performing on this vehicle. When these tires wear out I'll be doing a 3 - 4 inch lift and heading to some larger tires just for the appearance. Good luck !!!
You can substitute these tries if need be. But if you do this your car will be off balance.
no
Yes, you can substitute the 205/75-15 for the 215/70-15.
Yes, they can
Yes, you can
Yes you can
Yes, they can
No, that is a very bad substitute. If you want to go with a 70 series tire go with a 195/70-15 which is a great substitute.
The rim size must match the tires unless you also change the rims to match the tires.
It is an acceptable substitute, but know that your speedometer will read 58.7 at a true 60 mph.
