I've got 4.5"x10 MiniLifes with Cooper Offset on my Traveller. 165/70 10 Yokohama A008 tyres. Front brakes are 7.5" Cooper S and rears have spaced Minifin drums. I have KYB Gas-a-Just shocks ad have no clearance problems.
When I had standard drums all round I have 5"x10 Dunlop D1's with 165/70 10 A008's.
If you want a more standard look you could go for 4.5" Cooper S steel rims with hub caps
or perhaps some Rostyles as used on early 1275GTs
i wonder if these are 165/70 on this Rostyles???
