Re: Tire & wheel options for '67 105

[Sidney Gage <sidney_gage@domain.elided>]

John,

We have Dunlops on my wife's stock '67 GTV in 185/65-15 size on the
4.5"x15" Fergat wheels; they work fine. I vintage race my '57 spider on
185/65-15 Continentals on the original steel Borranis without problems.
There are others I run with who use the AVSi on 4.5" rims with no problems.

Be careful of the 105 15" Fergat steel wheels if you autocross or race; I
have seen them break in the center section.

Cheers,
Sid Gage
