Have just changed my 18" AMG Grand Edition Alloys over for some 19" AMG III and Goodyear asymmetric 2 tyres, look great! Will be putting the old alloys up on here and eBay shortly, they are in excellent condition and plenty of life left on the Dunlop Sport tyres too. Can I check the pressure the new tyres should be, I looked in petrol cap and seems to suggest 30 PSI for normal load but just want to check this pressure still applies to the change of alloy size? Was thinking of going bit higher just to allow for when load is slightly higher, say 32? Thanks All!
