New to the message board (just introduced myself in the newbie section) and was wondering if anyone could give me some pointers on installing Portawall white wall inserts? Took my 15" ones to a tire shop who said they had installed them before, but now I'm not sure they ever had. The inserts would go on OK until they starting putting air to the tire and then would "bunch" up in a couple of places and stick out from the tire's sidewall. It appears to be seated evenly around the wheel bead, but is definatley not right. The tire guy at first said it would be ok like this until I could take it home and use a hair dryer on it to make it lay down flat (ughhh???) When I told him I didn't think that was the fix, he said the inner diameter part of the Portawalls was too large for my wheel's bead and that was the reason of the bunching up. He said I needed to trim some of this off and it would work. This sounds more likely the reason, but after his hair dryer comment, I'm a little hesitant to follow his advice. No where on the Lucas Tire website where I bought the portawalls does it say that "trimming may need to be done". Anyone else have this problem with their Portawalls and found a solution?
