Re: Low profile tyres for Ute
I think you'll struggle to find anything suitable - even in 16" tyres there isn't anything else with the load rating as they were specially made for Ford 1 tonne utes. Perhaps there will be some alternatives in the future.
The other option would be to speak to Ford about how you could get 17's on. If only all RTVs weren't 1 tonners I suppose.
The only other option is just do it anyway, providing you will be within the load parameters of the new wheels and tyres.
