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.

EA90, my EAII has 225/60/15 Yokohama tyres all round on 7 inch CSA alloys.

Since I bought the car, it already had 225's fitted on - I'm not pretty happy. I need bigger.

235's front and 255's rear. I am not sure if the front can fit 245's but it would be nice!

(I contacted Beaurepaires and they have those sizes, aftermarket tyres, 235 and 255's... $700 approx for all but you have to get yourself the rims and mags. The front 7.5 inch and the rear 8.5 inches)

We beat the commodores, commodores only can take maximum of 225/60/15's!!

PHIL82,

We have covered this topic before have'nt we?

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.

the commodore can only take 225/60/15's? what are you on? how do you explain 235/45/17's on the ss, or the 20 inch wheels on the ute?

PHIL82

I'm talking about the VB/VC/VH and VK's can only take 225mm wide tyres... can be on 15, 16, 17 or 18 x 7 inch rims.

Maybe it's best to have 235/60/15's on the 7 inch CSA alloys I have right now.

EA90

I might go buy some 225/60/15 G-Grides or Eagle F1,s

Thanks again.

phreeky

what could i fit on the 15" S pack rims?

i would like to fit 225 on. could it happen, safely?

what sort of cost difference is there between 205/65/15s and 225/60/15s?

PHIL82

The 205/60/15 is the most expensive around $105 for each tyre and the 205/65/15 at around $90 each tyre.

Is there any such tyre size as 255/60/15's? diameter must be the same as the front for eg 235/60/15's to avoid gearing probs and speedo probs.

PHIL82,

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.
