The rules require a .375" width for the front of the F1. Looking at pictures throughout the blog it appears that some people run front tires wider than required. Opinions?

Thank you.

They look better.

They look better according to today's slot car sensibilities. To create a look closer to the real '60s F1 cars, they would be no wider than about 5/8 inch and the rears would be a bit over an inch tall!
I don't know if wide fronts hurt you much (except for rotating mass). In the turns, I doubt that much is in contact other than the outer edge of the outside cornering tire, regardless of the width.
Just this racer's 40% of a nickel.

Never complacent - striving to race to ever increasing levels of mediocrity!


The only thing I know about slot cars is if I had a good time when I leave the building! I can count the times I didn't on one hand!

The notion that one can have their slot car racing and EAT IT, too!

At HVR we make our wheels wider than minimum so they can be trimmed and/or retreaded by the owner without worrying about sanding the hub too much.

Most of the available tires are .375" to .400", so they're not hugely wider. JK makes a pair that are .420" wide, but they are not expressly made for Retro F1... but they work, and I have used them. I think the hub on those has a different offset.
