Although the sidewalls on an RFT are obviously stiffer is it still the case with a normal tyre at its proper inflation? i.e. an RFT with low or no pressure can support the car whereas a conventional tyre obviously could not. However, if inflated to the correct pressure then both support the car so exactly how stiffer, if at all, is the RFT? All I know is that you can specify NOT to have RFTs on many models and I doubt BMW change the spring rates should you select that option.
