Hello, i have a triumph TR7 and have some MGF 16 wheels to fit but am unsure what size tyres to use. The old wheels are 13 inch diameter and 5.5 inches wide with a tyre of 185/70R13. The new wheels are 16 inch by 7inch. what size should i use to keep the same over all size.

Thanks.

205 / 215 would be suitable I would have thought.

I think I'm running 205/225 45/50 R15 at the moment on my 15x7 compomotives.

I'll be running 245/40/R16 Toyo Proxes/R888s on my 16x8 MOs if I ever get round to sorting out my Toyo sponsorship again lol.
