Alloy wheels.

Hello

Do you mean the Alko wheel lock? Well you could use a good enough substitute like a Millenco Wraith, which in my experience is far easier to fit actually, or as you say swop the wheels over, I know what you mean by looking stupid to you, I'd be highly conscious of the fact too, but in reality no one sees both wheels at the same time and I suspect no one would notice. Or find an alloy wheel that looks more or the less the same?

Also steel rims are heavier, not sure if this would affect anything?

I assume you've tried caravan breakers? Just do a google search and few national ones come up.

Oh and check with your insurance about using a different wheel lock, some do stipulate a certain type.

If you can’t source one alloy wheel, why not find 2 steel wheels which will then match aesthetically and in terms of weight. You will, though, need more expert advice than mine as to size, stud fixing and type. Get those wheels balanced too 👍🏻
