Thread: Goodyear 2703 and 2704 Tires

  1. #1
    I was curious if anyone has tried the new tires by Goodyear yet? We are considering a switch from the Hoosiers to the new Goodyears....

    Since it won't be until early next year until we have access to tire data, I was hoping to see what experiences other teams have had with it.

    We're actually still using an old set of 2696's in those videos.

    We'll be jumping onto some fresh 2704s in about a week and then we'll get back to you.

    We just got a set, but have yet to run them on any decent surface. We are driving at a new location this weekend (hopefully better surface quality), so I'll post back if/when we get anything useful.

    We had taken them to the event but unfortunately.... we turned out to ineligible to even appear in the scrutiny. Maybe in a few days, we may be able to share the data.

    We recently ran the 2704 at FSAE Japan coming from the 6inch wide Hoosier which we ran at the 2010 Australia Comp. Whist we didnt do back to back testing, for our car id say they are good for an instant 1-2 sec for an 800m lap.

    The conditions in Japan were a lot different than aus (30+deg and a very smooth grippy track, compared to aus with 20deg temp and normal road surface), but to compare we went from 5.6 to 5.1 in skidpad with the 1st timed loop being the quickest of the lot. We drove the absolute pants off the car in the enduro and they didnt degrade at all.

    From my opinion in the seat.
    Avon - Grip like you would not believe for 1 lap then nothing
    Hoosier 6inch - Good life but takes half the endro to really start working
    Goodyear - Not as quick as the avon but lasts like the hoosier

    Thanks for your input on the tires Matt. So basically it seems like the middle of the road tire between the Avon and the Hoosiers. What about tire weights? Has anyone been able to confirm the actual weight?

    I'm looking forward to what some of the other teams think as well on here.

    2704 Weight is less than 4kg (or 8.5 lb) per tire totally green.

    We will be testing ours as soon as the car is back together after paint.

    We got 9.0 lbs on a pretty accurate scale.

    I think the pre-production ones were slightly lighter (8.5 lbs-ish).

    Yeah I know they were stating about 8.5 lbs for the prototypes in an older thread on here, so I was wanting to see what the actual production units weighed. So it looks like they are pretty close to the claims made in said older thread.

    Even 9 lbs is pretty light. I think the Hoosiers were around 10.5-11 lbs or so if I am not mistaken.
