My 67 Duetto has the standard factory wheels (15 x 4.5 steel) and the original tires were 155-15s and the car currently has 165-15s.

Without changing wheels at this stage, what choices do I have with regards tire sizes.

Someone once told me 185/65-15s would fit on these (15 x 4.5) rims. Will that work? What's the rule of thumb with what tire fits on what wheel?

Also - will I get rubbing with that size tire? How much heavier will the steering get?

Thanks for your advice,
