Tyre size for 19 inch wheels on airlift

[Marky1980]

Hi all, I have a set of 19 inch wheels that I have just purchased, vehicle has abp 3h airlift and have been told max tyre size is 255/40 but unable to find a tyre that has a suitable load rating, anyone else had this issue and found an alternative?
Thanks

Big wheels, air ride and correctly rated tyres don't go hand in hand. You'll likely need to accept a load rating under 100 if you want to fully air out.
