Often 2 or even 3 stints on the same set of tires.

Curiously, I have heard several (more) independent comments recently echoing the sentiment - re Le Mans, anyway.

Actually, there is an interesting Autosport article on the subject, though I am sure you will have read it. Gascoyne's comments were relevant & perceptive, I thought.

In the other thread it was said that Bridgestone want 80 mil$ from F1 to supply tyres. Michelin will not be asking for less. If the teams have to choose between 18 inch rims and paying 2 million more each team the discussion will not be very long. The poorer teams will all vote with their pocket books. So they better think how they want to implement it with the least fuss. A shake up like new suspension design isn't such a bad idea anyway. At the opportunity they can go back to wide 2000 mm tracks and 450 wide rear tyres, make the front wing visibility mandatory from the driver position and cut downforce to one ton maximum.

Might suit Michelin, JT. Apparently Michelin supplied 75% of the Le Mans starters in 2009 - most, if not all, using 18 inch rims....
Also.. I still say.. so what? 18", 17", 16", whatever.. big deal. And I'm sure every tire company I can think of already makes 13" bead diameter tires commercially anyway. Michelin certainly will be making more 13" radial race slicks in the next years whether they get the F1 contract or not.

What's the synergy between a 18" Le Mans tire, and a potential 18" F1 tire? Different loads.. different speeds.. different springrates.. different tracks.. different endurance requirements.. the list goes on.

Bottom line, there is no need to develop a totally new tire platform. Why bother, especially given that it's going to affect so many other suppliers and parts of the car?

Agree with your comments, except that I'm not totally sure the loads will be dramatically different. Neat way of hitting the reset button, though, if it turns out they are in a competition....

Is this a rumor...could be none of the tire producers are interested
in building the 13s, if so then its time to roll up the sleeves and
start with the new chassis.

13" rim are the most popular size for open wheels racing, the only reason for for going bigger is to fit bigger brakes. Also a stiffer wheel will mean that the suspension will have to move more than current. Which would adverse effect the Aero as the ride height would constanly changing. I think the FIA want to go back to the wide 18" tyres no increase the diameter. If they do that i would like to regulate the front rear wings and bring back ground effects and 2m wide track.

Motor racing has never been, and never needs to be 'relevant' to your every day car and driver. More often than not, technology is developed OUTSIDE of F1 and brought in, rather than developed in F1 and pushed out. That's the way it's always been.

Switching to 18" bead diameter tires just seems like extra cost for everyone for no real gain.
Totally agree. No idea why people think F1 should or could be this magical lab that can come up with better solutions than the already huge R&D labs present in big car manufacturers, despite having very different objectives such as say.... winning races.

I just happen to have a little more confidence in Michelin to know where the synergies are than in Jersey Tom from Akron. They have been in the business for 121 years and have quite a reputation.

For once I agree with WB, if the suggestion comes from Michelin, they should know what they are doing.

But anyway, I have a problem with the numbers here, a 5" increase of the rim, that's huge. Any ideas what that will mean for the tyre diameter, the same 5" and the cars will look totally unproportional with the same track-width, no?

I think they look great. Wider rear tyres and tracks would be even better.

They do indeed WB, but the tire-profile looks much less than today's 13", correct?
Increasing the track would be for the best in any context, the narrow track since 1998 has always looked odd to me.
