How much use does the Val get John? A mate of ours owns a loyd carrier and all of the return rollers have shed their rubber, its been like that for a few years and hasnt caused an issue, and he uses it fairly often. I mean, the tyre cant really go anywhere can it, its trapped in there. A Val does what, 15mph max? I don't really see it as much of an issue. But if you are really set on fixing it, have a yarn to your local forklift bloke, he should know where to get it sorted. But for a price ofcourse.
