You could look at downplating your van to a T30?I’d still be worried about insurance without running the correct tyre… but let’s not go there!
Thanks for the photos - I guess the issue I have is that I can’t find any tyres with a low profile like yours that are 103 load rated - they all require a stronger and bigger sidewall - so I suspect I wouldn’t be able to lower the van much and still drive it without the tyres rubbing on the arch liner or wing.
Appreciate your help and advice! Thanks.
