This is a wider replacement rear tire for the Brick McLaren F1 10330. It's about 50% wider and needs a few very minor alterations to the model (shorter 3-axle, floor needs to be set back bij one brick) which anyone can do.

It's still a work in progress. The current model is good enough to share.
I've been printing it in PLA up to now. It would be better off by printing it in TPU with the rim in ABS. Will try that in the future.

A special thanks to Balazs from RacingBrick who inspired me to make the model :-)
