So having had no look at finding amorak steels, a already have a set of 20” alloys fitted to my van, 20x8.5 40 offset, supplied by Salop vans, looking at posts on here I think they’ve fitted the wrong size tyres 245/45/20. So I’ve fit my standard 16” steels on to see how the van feels, what a difference, not comfort wise but gearing wise. My questions are? If I change my tyres to the correct 275/35/20 should it feel better? Also as the rims are only 8.5 wide will they be ok with a 275 tyre?? Thanks in advance.
