165/65-13 i think i was also using the same on my 1997 zen with HR alloys wheel,for sure the ride was bumpy

and i had installed spacer rings at the rear suspension,moreover the pain was no power steering and stiff steering wheel:( got fed up with this and then finally one sold it,but i did good outstations on that car without even a punture till date i sold.I was using goodyear.
