Random question with little or no point to it...... the 20 inch wheels on the insignia are 235/35/20.. can you actually get tyres for it!?! been doing some day dreaming on 'design your own' and wondered how much they would cost.. could only see a few and some are £200 each?! dont get me wrong, it'll be a long time before I can get one (dammit) but this is just out of interest!
