Maybe someone could reassure me that I have not missed anything here.
We run 2 axle urban tractors with single axle trailers. (basically ex brewery drays). Until now we have always used trailers with air suspension, (tractors have air on drive axle and plate says road friendly). Tax is currently £236 pa to run at 25t.
We now want to occasionally use a trailer with steel spring suspension, running at the same gross train weight.
I had the idea that this would increase the tax payable as the trailer would be “road unfriendly” but I cannot find anything in the tables to say that it should be any different and we can just hitch up and use the thing.
Any advice ?
