No!Will not fit.31x10.5 R15 will fit on 15x10. Yes, I have 32-11.50-15 on 15*8 wheels.
Yes, that is a reasonable substitution.
As far as I know, the different sizes you can fit are: 185/60 R15, 185/65 R15, 195/55 R15, 195/60 R15, 205/55 R15 and 215/50 R15 on the 6x15 alloys. Chris from DIDCOT TYRE & EXHAUST
Yes, this is an excellent substitute.
You can but your speedometer will be off. Want to go wider then go with a 195/60-15.
If the front tires have enough room to turn without rubbing anywhere,
Yes, this is a good swap and should work quite well.
No, your speedometer will be off and power and fuel mileage will be adversely effected.
185 60 r 15 could replace them.
If you use 185/75-15 it will work but barely. Your speedometer will read 58.2 at a true 60 mph. I would not advise this swap as your car will handle poorly and your stopping distance will increase.
It is ok, but lessens your overall stopping capacity, - WHY would you want to do that .
Of course not you cannot install 15 inch tires on 14 inch wheels or vice versa. 14 inch wheels require 14 inch tires, and 15 inch wheels require 15 inch tires.
