What is the best track tire for the Boss that is still streetable ?
I to had problems with the front tires the roll center is to great. 450 lb springs in the front and a good adjustable sway bar will solve the problem. No matter what tire you put on the left front will burn up with out spring changes on the track. I will be trying the Trefo once I go thru this last set of Corsa.s. Woodman says the Corsa is a street tire designed for the track. The Trefo is a track tire designed for the street. Good luck
Original thread question. And Bossman302F I interpret your question as to which tires are suggested to replace the OE Pirelli P Zero Corsa tires, ie you want to maintain the Ford developed stagger geometry and keep the 19" rims.
Hey Jim the Trefo tires do look interesting. The Pirelli website on this tire seems to comment in several locations it is not the best wet tire and was really developed for, “Designed for racetrack driving on dry asphalt.... P Zero™ Trofeo is not recommended for use in very wet track conditions.” My only concern with the recommendation is the tire might be a bit compromised in wet street driving, if that is an important consideration for Bossman302F. The picture of the “tread” looks a bit shallow to achieve the DOT street rating. It certainly looks like a good candidate for track and limited street use. Also a plus is this tire system is available in our OE tire sizes.

Ford20, the PSS’s will certainly do both track and street uses. As I stated in my post, I discussed follow on tires for my Boss when the PO Corsa’s were worn out with a driver who has tested/evaluated several brands and he very highly recommended the PSS’s as soon as I could. He indicated the difference is significant. I am told the Boss “team” wanted the Michlen’s OE but there were some internal hurdles which just could not be surmounted and Ford has had a longtime and good relationship with Pirelli (since Firestone Wilderness AT issue).

I appreciate the responses!
These are not for a DD.

I just ordered a set of sumitomo htr ZIII in 275/40/18 rear and 255/45/18 front for my track wheels. Have run these before in my Audi and while they are not the grippiest out there with treadwear of 300 they hold up very well and are cheaper than basically all other options.
That said I will likely go with nitto NT01's for my next round of track tires.

Although the formal introduction of the SVT Mustang is a ways off, (some say Spring 2014, some say Fall 2014) and testing/evaluation of many components continues in earnest, the photos offered in Post #11 (October 2013) of

clearly show the Michelin PSS's are being evaluated for this Mustang application. And to be fair along with Pirelli and Goodyear's offered in other spy shots. These tires would be Daily Driver tires for wet as well as track conditions. We will have to wait to see the ultimate selection but my next set will be the PSS.

What is the load rating on the 295/35R18? it might not seem important but a trunk full of luggage, a tank full of gas, defeating the speed limiter and trying to impress a car with your three favorite plus sized chicks could lead to some difficulty if the tires are over loaded.
My Hoosier recommendations ARE Department of Transportation (DOT) “approved” tires. See page 19 of the Hoosier catalogue under the category “Sports Car D.O.T. – Radial”. The tires have two small grooves in the mostly smooth tread to allow them to be legally driven on the street. However, Hoosier prominently displays on all its catalogue pages the disclaimer,
WARNING: DOT labeled Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire including DOT tires on public roads. The prohibited use of Hoosier Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in vehicle crash and possible injury or death.
I know owners in Arizona and California who routinely drive their Boss with these tires. They too do not drive their car in the rain which is what the thread originator stipulated. I personally would opt for the Michelin Pilot Super Sport tires as discussed in other threads.

I think if you are looking for a track/street tire you need to just view some tires like the Hankook RS3, BFG Rivals, etc. and spend the little bit of money and get a set of 18 inch rims. Once purchased the tires end up being alot less expensive, more choices , etc. over the years. Though one of the best choices , I believe , is to get used Continental Slicks from GT Racing ( at 100 a pop), or scour the Hoosier site for Continental slicks on sale , and just mount those on your 18 inch rims that you purchased. You will stick alot better, have more fun, and just keep your street tires for just that, as frankly can't say the Pirellis are a great tire for our car. Like others that listed about them, I destroyed a set of Corsas in a very, very , very short time, and two seperated.
So simple suggestion..........buy some Enkei rims, get used race slicks or get a set inexpensively from Hoosier Direct , and drag those to the track when you want to play.

DG, certainly understand your opinion not to run Hoosiers on the street. And just because many do does not make it “right” but the fact remains many do.
One question though, if “The DOT rating is irrelevant to that fact” as you opine, why did Hoosier bother to spend the time to certify and test their tires to DOT standards (if it is irrelevant)? From a business standpoint that does not make sense. And in my opinion it is certainly relevant.

The point is that being DOT approved does NOT make them good on the street...it simply means you won't get a ticket for driving them on the street. And since the guy said he wants them for "street performance" it would be best to suggest something that actually works well in street applications (i.e., tires that don't need to be warmed up to actually grip anything), instead of a track tire that just doesn't operate well outside of track environments.
Thanks, Joeywhat. Exactly my point. The DOT rating IS relevant!

Please reread my post. I already did this.
Yes you recommended a street tire...after recommending what is basically a track only tire in terms of usefulness.
We mount and balance all of our own tires and I am another one that would NEVER advocate running the Hoosiers on the street. They have a VERY light carcass and would likely fail very easily if you hit a piece of debris that a "normal" tire might handle very easily. DOT rating is cool so that in a pinch you could run from the track to a nearby gas station and not get a ticket. They're "da-bomb" on the track, but choose something with a little better headroom for running on the street!
FWIW, our favorite track/street tire for the Mustangs is the Hankook RS3's.
