Gday all,

I was wondering if a 235/60/15 will fit on a 7inch width rim. I wanna fit bridgestone eagers to a el ghia rim. i can also get them in 225/60/15.

Comments/thoughts??

Thx

Yes it will. I have them on my EA. They fill the guards nicely.

Just to be sure, are the EL ghia rims definitely 7"? Not 6.5"?

Yep, I believe they are 6.5" not 7'.

The widest you could comfortably fit on a 6.5" is a 215/60/15 or if you want bulging side walls, 225/60/15. Also ensure you rolling diameter is within required specs.

If you have the rims without tyres fitted, it might be best to measure them yourself. Measure between the flanges, where the beads sit.

I looked at one tyre's specs, a 265/35R18, and the narrowest rim it was designed to fit was 9".

My guess is they will rub bad. If so, where they rub will mostly be a product of their offset. 245 is the common fitment to these rims, i haven't heard of more than this fitted to the front. You could adjust the offset to remove any rubbing on the inside, but then being so wide they may rub on the outside, on the guards, and may project beyond the guards.

Maybe go for a 255 and make them work and show everyone it can be done! But patience and $$$ might be required.

I bet many would think a 235/75R15 could not be fitted to the front, but i am doing it.

Yes, they are 4wd tyres. 30mm hub adapters are required to clear the
EBII upper balljoint. Other minor and moderate mods are required to
prevent fouling. They project beyond the guards and rub them, so
something will have to be done there.

I think the EA stub axles are different, the upper balljoint may be in a
slightly different location, i hope to try them soon, but i can make the
EBII one's work anyway, so they aren't crucial.

As long as you don't have to repaint the guards i reckon it's pretty cheap.

EA to ED the stub axles are all the same, except for drilled and tapped holes for the ABS sensor. The changes were the upper arms as in placement of the hole for the upper balljoint.
I think the EF & EL stub axles might fit also.

255's might need a 5mm wheel spacer, if so, to test for clearance one
could fit 10mm of washers behind a 245, and without driving it of course,
see what it looks like and turn from lock-to-lock.

Thanks for that. Last week i tried a larger wheel on an EA and the upper
balljoint seemed in exactly the same position, which correlates with what
you say. I also tried to try an EF but the car was too low to the ground to
fully fit, but so far seemed if anything worse, so i gave up.

It seems i will need to do my guards and respray, to fit the 235/75R15's.
