Pop on wheel caps.

Might get a better response if we knew which model Hyundai you drive??

I have a 98 Pajero but they are aftermarket wheels, The caps are roughly 4in across.

Might get a better response if we knew which brand/type aftermarket wheels.............

Yeah,photograph your wheels ---without the caps and if you have any photographs of vehicle prior to theft this may also help.
Goodluck.

Interesting, I took my 96 pajero plastic centre caps off when the car was new so they wouldn't get lost on corrugations, or chipped/smashed by a stone, and placed them up on a beam under the house.

Painted the wheel centre and hub black and it doesn't look too bad.

How do you manage when travelling, or do you take them off for a trip and put them back on for around town?

The Mitsubishi ones off a 96 GLX most probably won't fit your non standard rims? Am in Brisbane.

I got some ROH caps and stick out watchamacallits the caps go on for a 15" alloys. Going back to standard toyos cause i picked up a bargain with coopers on with 95% tread. Might hold onto the wheels as get a bit more height and bag down well but couldn't be bothered holding on to the pretty bits.
