No, your speedometer will be off and power and fuel mileage will be adversely effected.
yes
Yes, this is an excellent substitute.
If the front tires have enough room to turn without rubbing anywhere,
Can you put a 215 70 r15 tire and a 215 65 r15 tire on same car
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
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.
185 60 r 15 could replace them.
Normally. yes.
Yes, you can
Yes, that is a pretty good substitute.
no there is too much height difference
