Hi, I have a set of Nankang tyres sized 165/60R12 that I was going to put on a set of alloy wheels i have.
Unfortunately i now have to sell these alloys, but was wondering if they will fit on my standard steel rims of my 1993 Mini Rio instead?
Or will they be too wide?
The standard size tyre for these steel rims is 145/70R12. It’s a 12 inch wheel.
Any advice most appreciated.

Shouldn't be an issue at all. There's not much difference between 165 and 145. Your speedo may read differently due to the slight change in circumference, but I don't think I know many Minis that have that accurate a speedo in the first place.

Depends on the width of the steel rim.
From experience, a mini wobbles like a jelly with a 165/70/10 fitted to a standard 3.5x10 steel rim.

Ideally for a 165 section tyre the minimum wheel width is 5".

Your steel rims may be stamped showing their diameter and width, so ideally you want to see 12 x 5J stamped on the wheel.

Thanks all for your replies. I will have a look at the wheel width tomorrow, and check the size and go from there.
Many thanks 👍

A 165 tyre will not fir well on a 3.5" wide rime. A 165 tyre is fine on a 4,5" rim and that is what most people fit onto the 4.5" 'S' rims and after-market 4.5 x 10 or 4,5 x 12 alloy rims.

You`re not wrong there

The Mighty Mini racers use the standard 4.5" width rim with Yokohama 165 tyres and it`s fair to say they can corner like they`re on rails so there`s no problem fitting 165`s to yours.

Yes they will fit. It seems some commenters have missed that it's about 12" rims and tyres.

I have been running 165/60R12 on standard steel rims for a while now with no problems. They are not nankangs but that is not really relevant. Thay do "bag out" a little more than on 4.5 rims but its not a problem. Thay will be fine.

I have heard of owners running an additional 4 or 5 PSI .

Just out of curiosity.....what does the J stand for as regarding width?

[stuart bowes]

it's a reference to the 'lip' or bead profile

 

I'm not sure if that's because it's a J shape physically or because A to I didn't work

[weef]

The letter "J" corresponds to the wheel bead profile, other letters are used but "J" is the most common on car wheels.

If you google "j designation on a wheel" there's lots of info.

Thanks all for the replies everyone. Really appreciate it 👍
Nice to know they will fit ok.
