6 inch Rim, how narrow can you go with the tyre ?

Ok, so I have some 6 inch Porsche rims and I want to put some narrow tyres on them...........how narrow can I go, REALISTICALLY ?

I have a 135 Nankang on a 6 inch as a spare, but i dont think i would drive very far with it !!

So maybe a 165 ?

Who has done this and what size do you have !

Cheers

Try plugging you sizes into this, it gives the safe rim widths for a given tyre size.

Cool..thanks for that 🙂

i have 145s on a set of brms up front of my bus n same on my beetles' radars..
works a treat drive everywhere on em n i think they are 5.5" from memory
so should fit nicely on the 6ers
135s maybe a bit ''aye curumba' at + speeds
