Sorry I know this has been discussed but I am not having any luck searching for it. What are people doing and reccomending for tires for their Shelby.

Buy ones that are round!

Whats wrong with the originals?

The GY F1 Supercar tires are a very good tire. Have you pushed your car on wet or dry roads? You may be able to find a quieter tire but highly unlikely you will find a better overall performing one. Or are you looking for smaller studded tires for winter. lol

The stock tires are not recommended to be used in under 40deg F temps!

I don't need to put my 2 cents in here, but I will! The OEM tires are a bit noisy, but I don't have anything to compare them with. The other top notch tires might be noisy, too, right?

But, I have looked at some stuff other folks have said here and there and a lot of guys seem high on the BF Goodrich tires, I forget which exact ones. And good things are said of the Yokohama and Nitto tires, as well. I am thinking that these last two tires might be softer and maybe have a little more traction.

There is another tire I have seen on several cars at the shows and it is a Goodyear F1, but it has a different tread design. It sort of looks like V's stacked around the tire. Anyway, I like the tread design a lot!

Now some of you guys that actually know about tires help us out!

Thanks!

PS: I think the ones I mentioned are all round!

Actually, to be more accurate, tires are closer to toroid in shape rather than round. Toroid meaning doughnut-shaped.

Sorry, the geek in me slipped out again. :D

I think these tires you are talking about are street stickeys.These are DOT approved street slicks and they can be used on the street or on the drag strip.Nittos are probably the best

No I dont have a problem with the tires, I dont even have my car yet, I just thought it would be neat to have the original tires from the car put away, to have in case I ever had to sell the Shelby. I am just looking for a replacement, I am sure if they work for Ford they will work for me. I did however call my local Goodyear dealer and they dont even have a price for them, anyway, round or toriod i dont care just something I wanted to do.

Keep in mind, tires do have a limited shelf-life. Just sitting in the corner, tires will last 5-6 years before they are unsafe to use. They dry out and crack.

old, The tires that come standard on shelby are Goodyear F1 Super Car tires!

The pricing I got at discount was 200 for each front and 240 for each rear. They had them in stock.

Yes, I know what the standard tires are. The tire tread I like is the Goodyear Eagle F1 GS-D3. I found it at The Tire Rack, but it might not be available in the 285's.

I like the looks of the tread design! Yokohama has one that is very similar to this, the Yokohama AVS Sport.

The Michelin Pilot Sport tread looks very similar, also. I found it in the 285.

I don't know how good these are, I just like the way they look!

Is there not something that you can put on them to make them last longer? I know maintenance on a tire that you're not using seems strange but I would think that you could treate them every so often to keep them soft.

I suppose putting them in a hermetically sealed container of some sort would slow dehydration of the rubber, and the addition of some sort of non-petroleum based tire dressing may help. I've never tried storing tires for an extended period of time, so I couldn't tell you what works for sure.

I had a 67gt500 with an original spare in the truck looked good after 35 years there. and it had non-original but 1967 dated tires on the rear that looked super still after 35 years. you could store them out of the sunlight and they should still look good for show 40 years from now just not sure if i would run them.

As an old Mustang buff from way back I can fully appreciate the desire to "save" those old tires but really, what did you buy the car for, a concours show piece or a 500HP fun machine? Don't tell me.... save the tires so I can pull them out in 30 years... after I pull off the small pulley, the nitrous and the No-cat exhaust! Ok, to each his own.

I do plan to get another set of tires and wheels though. A set of sticky track tires for those 130MPH weekends so I don't tear up those nice F1's in about 3 or 4 weekends. I'll save them allright; for the street!

Seriously, I read somewhere that the design team had done extensive research on the tire/wheel combination on this vehicle and had found that the 18" wheel actually had advantages over a larger 19"+ size. Something about rotating mass and unsprung weight, etc. I'll have to look around to find that article. Anyway, I think staying close to the factory size of 18x9.5 will probably yeild the best results. Even the FR500C uses 18x10's and the FR500GT gets 18x11"F/12"R. So bros, resist the 22's if new wheels are in your future. And tires I guess it all depends on your usage; cruising, show, drag, road race, maximum fuel economy and tread wear, well maybe not that, but whatever.

I'm w/you CajunCobra...I read that same article somewhere, but damned if I can find it now...there was a considerable amount of time spent @ the track using different tire/wheel combos on the test mules before the engineers arrived @ the final destination. Perhaps 07 can chime in regarding the early stages of testing :confused: I'm pretty sure our Prez and staff physicist (rpretzel) can give us the scoop on the physics of the whole deal...If its a certain look a person is trying achieve, they may end up chasing their tail and going backwards w/regard to the cars handling characteristics...:)

I plan on lighting them up too but I just thought it would be nice for show or even when I go to sell it to have the OG's to throw on, thanks I kind of looked into the 19's and found the same thing, if 18's are good enough for Ford they will work for me.

At first I was considering purchasing different rims and preserving my original rims for posterity sake. Upon delivery of my Shelby I liked the stock rims so much I decided to purchase an additionsal set of stock rims for the future and enjoy the ones that came with the car and doing a rubber change when old Abe said it was time. Just found the stock rim price on Ford Racing and they are not as bad as I had expected. $299 per rim including the SVT center cap. Alot less than I had expected so that is my plan. Just thought folks would like to know. I will try and get my dealer to get me the rims at dealer cost and will post that price when it is available.

yeah thats a good idea too, i am a pretty big fan of the stock rims myself, man i was looking at the dates in which your car was shipped and delivered etc, mine could be here anyday, I can't wait. Its only supposed to be 55 deg here this week but I wont notice it with the top down.

I believe the owners manual states the tires are rated to a minimum temp of 40 degrees F. I'm guessing that below 40 degrees, the rubber hardens to a point where you begin to lose traction.

Yes it is true,like Rpretzel said 40-42F you start losing traction and a lot of wheel hop.If you are in a cold climate and you are going to drive it in the winter it is recommended you change tires.

Aldy

Thanks rpretzel and 07. My car goes into strorage the beginning of November so I'll make sure not to drive the car if the temps go below 40 until then.

Under 40 degrees F? We might get down there 10-20 days a year here in the Charleston, SC area. We lose traction running over squashed mosquitoes here!

This is a myth. The tire companies will use this scare tactic to sell tires. I purchased Dunlop GT Qualifiers for my '69 Camaro in 1987 and am still driving on them today. If anyone can show me one documented case of a tire failing simply because it's old, I'll buy them lunch.

Ok how about Outback?

I have '68 Stang that had BF Goodrich T/A's. I'm not sure how old the tires were but when I bought the car it had those tires and I've had it for about 6+ years. The tread depth was fine with probably over half the normal wear still left. Air pressure was kept within specs, no rough driving either. This car is a cream puff. Anyway, one day my daughter complained of a vibration in the car at highway speeds. I checked it out and a belt had slipped or something inside the tire and there was a lump forming that progressively got worse until it was noticeable at 10MPH. Off with the tire and on with another (Dunlop D40) I had lying around. About a week later, another one on that car did the same thing. Changed it and kept driving. Another week later, same thing. So, I went and bought whole new set. Whether the fourth tire would have failed will always be a mystery but it is strange that it all happened about the same time.

With several old Mustangs around here many don't get driven many miles as I would like but I do my best to wear the tires out instead of the alternative. This car was just such a cream puff it didn't get the kind of attention that wears out tires. Anyway that's my story...

OK, How about Sonic?

It would be interesting to see the bump you describe. Almost all tires (except Bridgestone I believe) are made with 2-piece molds. For this reason there is a parting line in two places on the tire, and you can see this on the sidewall. Some people call this a "bump". Perhaps yours was something different...can't say without seeing it. Good to know you're safe now though.

Dave

James Lanier
11-02-2006, 06:26 PM
All those tires are gone now so the location of the "bump" will always remain unconfirmed but the bump was more than a ripple in the sidewall. The tire size was 235-14-60. After the "bump" appeared, it looked like a 70 or 78 series tire in one spot and a 60 series tire on the rest of the tire. Weird!
