hi people. can some one tell me what the original wheel and tyre size is for a jdm pulsar. have got 17`s on at the moment with stupidly low profile tyres on, which is fine for any town dwellers but i live in the arse end of nowhere and the roads are shite, also its affecting my acceleration and speedo reading. so would like to go for some 15`s or16`s which work out at the same rolling radius as originals. also does anyone know of abs problems due to larger rims.get a bit of pedal pulsing when light braking. cheers.
