Just been to have my tracking done , and the nice man said, that the wheel size on the rear are to small, they are 225-50-16 and should be 245-45-16 any thoughts if this is correct ,ta

Are they stock JDM wheels?

Yes si

Then 225 50 is correct. He maybe looking at the data for UK cars as they use 245 45.

Ta si , he said they put bigger size on the rear to help the handling at speed , should i leave alone then or would it help ?

UK cars had a 8.5" rear wheel with 245 tyre

JAP cars had a 7.5" rear wheel with 225 tyre

Ta for the info , now ive new shocks , its a bit more lively on the rear on pulling away, if i put the 245 on would that help [ more tread on the road ]?

Just get some UK rears. It'll look a LOT better as well. If you put wider tyres on your current wheels, they'll roll more on the rim.

Getting my clutch replaced first , so new wheels nxt , thanks for all the info

ahh..just seen your sig pic. They are 200sx S14 wheels.

I know , they look cack , i will have to put a new thread up for a set of uk wheels , and ive only just put 4 new tyres on lol
