Hi..... again. A couple of things... My 1974 camper has lowered suspension on BRM replica alloys and I'm unsure what tyre pressures to use back and front. The camper is away having new roof gas struts/clamps fitted so I can't tell you what size wheel/tyre, but they look like any other bus alloys/low profile tyres...any ideas?? secondly...I've just had to reregister from scratch as website didn't accept my username/password. Any system adninistrater out there know what went wrong?
