Looking for tyre sizes for 13" Wolfrace Turbo Vecs

Hi,

I have a set of Turbo Vecs I've had refurbished recently and am wanting to put on my '88 Caddy pick-up, they're 13" and 7" from outside of flange to flange.  BUT I'm stuck on tyre sizes.  I've asked on the Caddy forum but not really had any responses so far.

I currently have 195x50x15 tyres on the ATS Cups my Caddy came with.  I'm looking for something smaller diameter, not looking for stretched tyres but don't want a huge side wall.  I want something quite a bit smaller than my current set-up though.

Any ideas please?  Also my speedo works out more than 10% above what it should be according to my sat nav with the Cups so really looing for something which wil take that down allot, I can't remember wich way it works on the old speedo drive stuff with rolling diameter sizes.

Here's a quick shot of one of the new wheels if it helps…



Any ideas please folks?  (need some centre caps also if anyone has any good non E-Bay ideas)

Thanks,

Richard

Your reducing the rolling radius of the wheel so your speedo will always be out unless you go to a high profile tire . Think 155/70 or 75 /13 work well on a 7j .

Check wheel whores for stuff like that probably more knowledge over there .

Is that an error? do you not mean 175/50x 13, a 155/70 is a tall narrow tyre more suited to a 5 inch rim.

yeah ! sorry just re read your post !

Lads, cheers but forget this one -checked them against the Caddy today and they don't clear the brake callipers!!!  Putting them up for sale as I have seen Golfs with hem fitted -I don't want to muck around making something fit or have to buy spacers.
