Lisa Needs Braces (tyre question)

I'm in Ireland and my 91 High Top Camper LH119 4WD failed the DOE test, I knew it would I need new sills welded on the dreivers side and around the side back windw. It's booked, I'm aiming for a respray too but other things keep cropping up and sucking money from the budget.

The passanger side front wheel baring was loose and needed adjustment. Got that done and mechanic siad that I need a new tyre as it worn on the inside.

At the moment I've Marshals Light truck load index is 106/104. Can't fault then but can't get them anymore. I'm looking at two of the below for now on the front or back and then later I'll get the alloys refurbed and two more.

re: 100T tyre rating

100 = 800kg per tyre (x4 tyres = 3200kg total load capacity - standard Super Custom weighs 1800kg)

T = speed rating of up to 190kmh ..but good luck there    

Must get mine weighed the test says it's about 1400kg an axle so I was working off 2800kg want some over engineering head room. It's a 4wd high top camper
