[Roadsters] wheel size

[Gary and Cindy Ault]

Dave,

Is the factory offset +15 or (-)15?  It's been too long since I looked
into wheels,  but something tells me it's (-)15.  And, I think the (-) means
the plane of the mating surface is offset towards the center of the car --
meaning the outer edge of the wheel rim is furhter out that with a + offset.
 What sticks in my minds it that cars with front wheel drive had positive
offsets, meaning the wheel rim was more towards the car.

What's the straight
skinny?

Gary

William,
On the '70 a +12 may work for you depending on your ride height and tire
size.
We recommend a +18 offset in a 15x7 with 195/60 or 195/65-15 tires.

The 73mm
center bore does not fit most front hubs. You will need to either
modify your
new wheels or use a 1/8" spacer. This will allow the wheel to
clear the front
hub register.

Also the studs may need to be swapped out for longer ones. The
late model
alloy wheels with conical seat lug nuts are thicker than the OE
steels
which can leave you with too little stud/lug nut thread engagement. You
should have 10 turns from start to tight minimum, if not you will need
longer
studs.

We have spacers and studs should you need them.

I hope this helps.
Thank you,
Dave Patten, Owner
