Guys u know i got a fairmont ghia i just wanted to know what is the maximun diameter of tyre can i get on my fairmont ghia rims. IE can i get 225/60/15 on them with out doing much damage to my speedo readings.
I'm pretty sure thats the maximum limit for the fairmont ghias. I have an S-Pac with the exact same tyre ratio.
Standard they come with 205/65/15's.
But without changing rims, the 225/60/15 would be the biggest you could fit, especially without affecting your speedo reading.
The 225/60/15 are almost exactly the same diameter as 205/65/15 so will not affect gearing or speedo accuracy noticably. I have had them on ED Classic 6.5" rims no problems.
235/60/15's will fit on 7" rims, don't worry about the 7.5" - too hard to find and hardly make any difference.
255/60/15 are getting a bit tall (large diameter) and will also affect the speedo & gearing.
As you have told us before that what you have is BALD please just go out and buy something.
Yes, there are 255/60/15's but they may be hard to find.
No, gearing and speedo have NOTHING to do with the diameter of the front tires, it won't be affected if the front & rear diameter are different. It ALL depends on the rears.
Why do you believe that 225's are the widest that will fit early commodores and EA-EL falcons. It all depends on wheel offset being correct. Brock VK Director Commodores had 245/45/16 as standard! Amazing what you can do with wheel offset and still remain within the confines of the wheelwell.
As I have said before there is even an EL parked nearby sometimes with 265/50/15 front and 275/50/15 rears all on 15x7" chrome 12-slotters and yes it all fits under the gurads and doesn't appear to rub, I've had a good look.
Not to my tastes but to each his own.
