Technical  wheels

Go to www.oponeo.co.uk look at Steel wheels and record the details and compare. ET is the offset, how far from the centreline of the wheel the mounting flange is. A larger ET will move the same width wheel inwards. Gets more complicated when larger width wheels are fitted. If moving from a 4.50 width to 5.00, the rim is half inch wider (13mm approx), so the ET needs to be 6-7mm less to keep the wheel centreline as was. Check however that there is room for wider rims without fouling suspension or bodywork. (Sorry its not a simple thing, which is why so many end up with fouling issues.)
