Does anyone know the widest tyre size that will fit the std Mk1 steel wheels.

Ta

ideally the rim width should be 85% of the tread width and not less than 75%

MK1 on 12" Rims ?

165/60x12" --- even that might be a bit too wide, tyres which are on the wide end of the fittment range for a rim tend to muck up the handling the original 155x12" is a better bet.

I thought they were 13", maybe that's Mk2

RS MK1 models were 5.5Jx13 all the rest were on 12" rims as they cam from the factory although a few 1300GT may have had 5Jx13".

Ahhh right, thanx for the info. Need 13's

I think you would have real difficulty getting any choice in 12"

Mini's have 12" wheels so there is quite a choice but i want 13's. Ebay has come up with some nice wheels so i'll keep my beedy eyes on them!!
