Tight wheels

Bought a set of alloys to go on my td5 90, the steels went on and off fine, but the alloys (off a 2010 90) are a really tight fit. They go on ok but coming off they need a whack with a rubber mallet to get them moving.
There’s a slightly raised edge on the inside of the hub, seems to be what’s making it tight. Wire brushed the hub and wheel, surfaces all clean.
Attached a pic so you can see the wheels.
Are they usually that tight??
If anyone has any ideas I’d be grateful of why it might be doing it!

Are they new or used?

They were used. No corrosion tho.
Came off a 2010 defender 90.
Different hubs possibly?

I may be wrong but it was my understanding that alloys centre using the hub centre unlike steels which centre using the conical nuts. if this is the case surely it is supposed to be tight as that is what keeps the wheels central on the hub.
I also know that to remove the alloys on my dads peugeot you used to had to really clatter on them with a soft headed mallet and they were the original factory wheels. That was apparently something do do with the dissimilar metals of the wheel and the steel hub. So may not be a problem.
I however have no experience with alloys on my 110, I prefer a wheel which can be hammered back to vaguely round with a rock when you bend them in the field

Yeah knew alloys usually hold on the hub as well as the nuts, just seems really tight.
It’s ok unless I get a puncture!!! Now added a wooden block and the rubber mallet to the tool kit!

Maybe a clean up of the wheel center with some wet and dry and a smear of copper slip?

As above, post #4 - alloys mount to the hub, steels to the studs and held by the conical nuts

Of the 15 (!) LR Freestyle alloy wheels over two D1's, most are just a nice push fit, but two of them are quite tight - and one of these is a cow - IMHO, it's "normal" more or less, but a good wire brushing of the hub, and some copper grease ( as post #6) should help matters.... If you CBA'd ( ) you could try moving the wheels round to see if wheel "#3" prefers ( ) hub #2 etc....

Failing the CBA'd - just use a bigger mallet

Get the grinder out.

I was wondering if they have been powder coated and some has got in the centre? Also was it cold? The alloy will contract quite a lot compared to the steel hub. Be interesting to see what the fit is like after some heavy braking. I agree they centre on the hub, but they don't need to be an interfearnce fit.

Wire brush and copper are the next things to try, grinder is on standby!

Hadnt thought about the cold, the hubs were warm I’d guess but can’t see it’s make much difference. Hub would warm the alloy! Can see where your coming from tho. Ideally a cold hub and warm wheel!!

This would be my first action
