K11 wheel & tyre setup

I have recently purchased a set of
JBW ultra rallys and they are running new continental tyres that are
175/50/13 7j
And I have run into a few problems in terms of poke

I am wanting to lower it obviously, which would be the best way of going about that, as I'm on a budget....and want some low

Regards
Brad

Your tyres, at 175 width, are too narrow for 7J rims, the tread blocks will close up and not work as designed in the wet, they should be at least 195 but 205 would be optimum......... as a rule of thumb the wheel width should be no wider that 90% of the tyre width, with 175 tyres the wheel width is greater than the tyre width....
