Witht he common sized federal tyres over 18 inch, you can normally screw the RRP down a fair bit, I know that with a couple of sizes alone in the federal range, the RRP price is like 80% markup on purchase price, so keep an eye out for the best deals, also the price of federals dropped in all comon sizes about 2 months ago, and most tyre places havent passed the price drop onto the customers, so once again, ask a heap or questions and try to get the best price., I wouldnt pay anymore than $480 for any federal passenger tyre, unless it is the RS's then you will be paying a little bit.. keep that in mind.
