As okay as they look, the rims are just another answer to a question no one asked.

Here's the question - why? Why make the change? All fundamental changes like this are extremely expensive for all involved, so what's the justification?

I would much rather see wider rims and tires, than larger rim diameters.

I have to agree with this. This isn't a case of applying F1 technology to the road, these tyres are not designed to be anything like that, so just give them fat rear tyres and drop the wing levels.

It will be interesting to see how the brake shrouds would change with larger brakes.

Brakes such as those used in WEC might work pretty well. Those brakes are good enough to stop cars twice the size of F1 cars and last 24hrs doing it too...

I liked the rims. I have to accept that I was skeptical but that car looks better with the those rims. And it looks like teams may develop around that area if it is allowed to do so.

Would like to see what 15" look like.

If I am correct they are also looking at 18" rims due to the fact that Michelin would only comeback to F1 if they changed the 13" rims... Also look at LMP1

Brake thermal management is always going to be an issue, big or small. The bigger one could be more of a problem as it could cool down too much and glazing the surface.

It wouldn't have to be as hot in the first place. So i wouldn't expect that to be as big a problem as with these tiny 11 inch ones or whatever they are.

or they can "keep" the old temperature range and make the brake caliper much much smaller thanks to greater distance of the pad contact patch from the wheel rotation axis (larger diameter brake disc)

most likely it would depend on if they need that head to radiate to the rim and help with the tire temperature management

edit: anyway, would be interesting to see what teams would come up with, except, most likely, it would again be "locked" down by myriad of complexly worded, non explanatory regulations, which can be used by CW to direct the development any way he may like it to go, to keep the show going

Has it been stated that the regulation concerning maximum brake disc diameter will change if there's a move to 18-inch wheels? Thus far, it's been discussed like an increase in brake diameter is a given with larger wheels, but I've seen not seen it addressed directly from a regulatory standpoint.

11.3.2 All discs must have a maximum thickness of 28mm and a maximum outside diameter of 278mm.

I'm afraid that's what a lot of fans will do, and , unless the FIA takes steps to Speed up our beloved F1 cars, they'll see that they are slower than other series, such as LMP. ....And the LMP cars look more spectacular too...I hope this is a small piece of a large package...

am i the only one that isn't keen on the 18s? i just think that the 13s with big profile tyres have been the staple of F1 for so long its a quintessential part of how they look for me. Maybe with time i can get used to it like other changes we've see but currently these bigger wheels seem ott to me like some MAX POWER magazine hot hatch a few years back complete with tiny brakes. The rear wheel doesnt look so bad with its deep rim but the front looks awful

I guess that makes two of you.
