Painting the inside of resin wheel?

[rollindown75]

Guys,
Working on a piece that has resin wheels. Got the outside of the
wheel/tire painted black but, I'm wondering how to paint the inside rim.
(which is red) Normally, the wheels i use (Hepra,Promotex,etc) I take
the rim loose from the tire, paint the rim, then slap it back on. Good
to go.In this case, The tire and rim are one. Any suggestions/ideas on
how i can paint the inside of the rim without painting the outside tire?

Paint the wheel first, then the tire. Then, if you make a small error, you can go over it with the darker tire color.

If you can make an axle for the wheel, you can rotate it while holding the brush steady, which makes keeping the width and placement of the paint easier to control

I find that unless you are modeling a set of BRAND NEW, less then 1 mile on then set of tires that color black isn't quite right. Even Flat Black looks too "clean". I like Floquil Weathered Black for my tires. It's not too black and givrs a looks a little "used". Kind of dirty like car tires look. Also unless your modeling a newer car the wheelwells are not Flat Black like lots of peolple paint them. If you look at older cars the wheel wells and bottom of the car is actually Grey! To each is own. I will admit that I don't always follow this rule. Sometimes the wrong colors look better. a good example is on model trains from the steam era. USPS mail boxes should be painted Olive Drab. However dark Blue with a Red top a looks a lot more like a mail box.

Flat black is even wrong for new tires. It's actually too strong a shade. Even new tires are actually dark gray and usually have have a slight brownish cast (what's called a "warm" gray). The longer they have been on the road, the more pronounced the brownish-gray color. This is because of road dust and other grime.

Weathered Black is good, as is Testor's "Rubber" though rubber is better for tires that are used offroad or unpaved roads, like military vehicles or farm trucks. I have also used a mix of a little flat black with Rail Tie Brown.

Try experimenting a little bit with various mixes. Take a look at the tires on your own vehicle.

First off, let's try to put these kind of questions in the "Workbench" section. There's a basic rule in modeling that lighter colors be painted first, that being said the above advice on painting the rim first is right on. I airbrush one piece wheel/itres the color I want first by putting them on some double sided tape and mounting them on a scrap of wood or cardboard. Again the above advice on tire color is correct. Dark gray with a spot of brown is most convincing. I've been using PolyScale oily black for this and paint the tire part by hand. I just posted a good example in the "all done" thread (Chester-finished) of the one piece plastic wheels from Roco.

Thank you all for the advice on tire colours. I am quite tired of having to mix new shades of brownish greyish black every time I have to paint wheels. I will have to go get a "weathered black" and an "oily black" and compare the results.

I use a round object like a bottle cap to hold resin wheels for painting. Tape the wheel to the center of the cap. Then you can easily turn the cap so that your brush is always at a comfortable angle for painting the rim.
