What I did to get a good feel for paths, was to make a box using four points and dragging the sides to make it a circle out of it. It's fun to make crazy curved paths, too.

Amazing PM. I like the texture you have in the tyre

Unfortunately I cannot get past the first airbrush step. It doesn't look correct.
I have tried the bump map step but it still isn't looking right. Specially if I am to have a plain area outside and inside the tyre. It's not happening for me

Looks like I am the only one having trouble. Have tried 4 times unsuccessfully now.

Thank you Photomaster, great technique for getting the rubber Tyre effect. I think I get what you mean sallyanne, I'm going to have another play to get some smooth radial strips.

RJKD, It looks like some monster truck tire you have there!

Sallyanne, what's happening when you try?

I think I got the paths down pretty well now. Here's a modified version as a Drag Slick....

Racer-x, that came out awesome!!

PhotoMaster - thank you for the tut/learng exercise; great idea to create bump maps.

The Downunda Wunda! I love the fancy rim!

Sorry didn't see your reply yesterday (I will try it again and if it comes out the same I will post the xcf so you can see)

Cool name OMG!

Only thing I did different yesterday was I saw the 15% as 18% (85% I saw correctly) so put the guides in the wrong place. [The airbrushing was either filling the whole image and leaving just the corners.]
I have finally done a simple tyre - no background. I didn't run the 3D bevel on it either as I cannot find it in gimp. I have installed it twice. I never have trouble with installing scripts and finding them

hehehe....really funny, Sallyanne!

I love it Sallyanne!
