Anyone else had any problems with the Goodyear tires that come on the 2013 Shelby?
I have had a blow out and the dealership has replaced it but now they tell me I can't drive it below 45 .

Hello this is Oklahoma . It's below 45 in the winter. I won't drive in rain or snow unless I'm caught in it but they forgot to tell me until I bring the blowout in to be fixed.

Any idea what tires I should replace on the car? 19 on front , 20 on back.

You could never drive the good years below 45 mph. Read your owners manual. Replace them with winter tires pirelli sottozero series II. 255/40 front and 285/35 rear. Again read your SVT owners manual all of this is in there

[Supercop29]

I try not to drive below 45 mph , but they are saying 45 degree ...
My complaint is they should have told me before or as I was buying car.

They didn't so ill live with it,

Even Goodyear provides the disclaimer regarding temperature.  In order for the tires to perform as advertised, they need to be hot.  A lot of cold weather daily drivers replace the GY with Michelin or Nitto's but there are several options.  Also, a lot of cold weather daily drivers keep the GY and are aware of their limits.

I live in OK too. I just keep them on and drive carefully. Too much trouble removing and adding tires. Bad things tend to happen over-handling 20" rims and low profile tires. If I was rich I would get a new set of rim/tires for winter.

Something to keep in mind.

Thanks Snoopy, good to know.  Thankfully my car is garaged so it doesn't get too cold, but I'm going to be extra careful for sure.

The dealers don't know much about their cars in my experience, much less the tires, so they are unlikely to inform you that the high-performance tires are relatively useless in lower temps.  So, it's left up to the customer to just "know" and the auto companies and dealers believe that, since everything and anything is CYA's with gazillions of disclaimers on brochures, signs, websites, documents or whatever, that there is no need to say anything.

Mine is a daily driver and I replaced mine at 16,000 plus miles before the second winter came up.  We don't get many days below 40 degrees, but I did notice I'd kind of skip and hop when going around a corner at lower to medium speeds until the tires warmed up a few times.  Once the tires were warmed up a bit, and I don't mean a smokey burnout, they were okay.  I never did like (i.e. trust) the wet handling of the Goodyear F1's that came on the car.  They were great on dry warm days.  I replaced mine with Continental Extreme Contact DW Tires and have been very happy in daily driving to include wet and colder weather.

My 2008 has a sticker on the door jamb stating that the car is not to be driven below 40 degrees with the factory tires.
My 2013 Focus ST has a similar sticker. But the Focus one isn't as strongly worded.

I also am running Continental Extreme Contact DW. They are another summer only tire not intended to be driven in freezing or near freezing temeratures. But, they stick to the road in the cold way better than the Goodyears did.

There's a warning label on your cars B-pillar (door frame) that clearly states you should not drive with those tires on cold days. I think my 2010 says 42d but I'd have to check to be sure.

And it doesn't even take that low of a temp to turn your Goodyears to stones.

I've posted previously (and had others confirm it) that on a 53d day my car acted like it was on ice going around corners.

If you drive it on cold roads, you're on your own.

It's not just listed on the B-pillar, it's in the owners manual too. And possibly in the glovebox on the inside of the door.

It's the *tires* that keep you from driving the car in cold climates so change the tires to all weather tires and you can drive your car safely in cold weather. But then they aren't going to grip like the F-1's or G-2's when the weather warms up so when you spin it out in good weather....(i.e. same boat: "You're on your own").

Your car has 662HP, it's not a Datsun! You *need* grip, cold OR hot weather.

I basically choose to drive on my original tires as-is during the winter, but certainly not on any snow or ice.

I drive very carefully and slow, knowing traction is minimal. My only concern is damaging the tires.  WIll they become damaged in cold weather if I drive very slowly and carefully?  No fast corners, no fast acceleration.  Last winter is seemed to work out fine.

From the 2013 GT500 Owners Manual Supplement:

Tires
Your SVT vehicle is equipped with low profile, high performance tires that are designed to optimize the driving dynamics you expect in a SVT vehicle. These tires are not optimized for off-road or winter (snow or cold weather) performance, and their ride, noise and wear characteristics are different than non-performance tires. Also, because of their lower profile, the tires are more susceptible to damage due to potholes and rough roads. To make sure that your tires perform as intended, it is important that you maintain your tires properly:
• The Shelby GT500 original equipment tires are optimized for performance in both wet and dry conditions. Ford does not recommend using the original equipment tires when temperatures drop to approximately 40°F (5°C) or below (depending on tire wear and environmental conditions) or in snow/ice conditions.
• The Shelby GT500 P265/40-19 front, P285/35-20 rear directional tires were designed for track use and may exhibit significantly reduced tread life and increased tire noise compared to the standard equipment tires under normal driving conditions. Increasing the front camber settings beyond the factory settings may further accelerate tread wear and induce tire noise.
• Note: Do not use tire chains on the original wheels and tires of your vehicle. The use of any type of tire chain on these tires may damage your vehicle.
• For tire pressures, see the placard located on the B-pillar inside the driver’s door.
• Always maintain your tire pressures according to the tire information placard on the driver’s door jamb, using an accurate gauge.
• Tire pressures are specified cold and should be checked after the vehicle has been parked for at least 3 hours. Do not reduce pressure of warm tires.
• Check your tire pressure often to maintain it properly. Tire pressure can diminish over time and fluctuate with temperature.
• Do not overload your vehicle. Maximum vehicle and axle weights are listed on the tire information placard.
• Extra caution should be taken when operating the vehicle near its maximum load, including assuring proper tire pressure and reducing speeds.
• Extra caution should be taken when operating on rough roads to avoid impacts that could cause tire damage.
• In the event that you encounter an abnormally harsh impact, inspect your tires for damage.
• Inspect your tires for damage on a regular basis. If a tire is damaged, replace it immediately.
• Proper suspension alignment is critical for maximum performance and optimal tire wear. If you notice uneven tire wear, have your alignment checked.
• Rotate tires as recommended in the following section Tire rotation.
• When replacing tires, the only way to maintain original performance is to use the original equipment tire. If a different tire is used, it should be the same size, speed rating and load rating and be replaced as a set of four. Never mix tire brands.
WARNING: For vehicles equipped with performance package tires (P265/40-19 front, P285/35-20 rear), only replace wheels and tires with the EXACT original brand, size and construction tire with which your vehicle was originally equipped. Use of any other wheel/tire combinations, even with identical size ratings, may result in insufficient running clearances, tire rubbing and eventual puncture.
Loss of tire pressure could lead to a loss of vehicle control leading to serious injury or death.

Summer Tires
The Shelby GT500 is equipped with D.O.T. approved ultra high performance summer tires with track capability. The rubber compounds used in these tires lose flexibility and may develop surface cracks in the tread area at temperatures below 20°F (-7°C). Always store your tires indoors at temperatures above 20°F (-7°C). If the tires have been subjected to 20°F (-7°C) or less, warm them in a heated space to at least 40°F (5°C) for at least 24 hours before installing them on a vehicle, or moving the vehicle with the tires installed, or checking tire inflation. Do not place tires near heaters or heating devices used to warm the room where the tires are stored. Do not apply heat or blow heated air directly on the tires. Always inspect the tires after storage periods and before use as outlined in the Owner’s Manual. Ford does not recommend using these high performance summer tires when temperatures drop to approximately 40°F (5°C) or below, or in snow or ice conditions.

Winter Driving
The original equipment tires on your SVT vehicle are designed for maximum performance in dry and wet summer conditions. They are not designed for winter use on ice or snow and cannot be used with snow chains. If you will be operating your vehicle in these conditions, winter or all-season tires must be used.
• Use winter tires with a V speed rating and a 93 load index or higher for all models. You may also use P255/40R19 winter tires with a V speed rating and a 93 load index and 19 inch wheels from the 2010-2012 model year Shelby GT500. Using these wheels will provide adequate brake and suspension clearance.
• Do not use a winter tire with less than a V speed rating, and even with clear, dry driving conditions do not operate your vehicle above posted speed limits while using winter tires. Never perform high speed driving with winter tires.
Please call the Ford Performance Info Center at 1-800-FORD-SVT (367-3788) for specific winter tire recommendations.

Tire Rotation
Note: Your Shelby GT500 tires (P265/40-19 front, P285/35-20 rear) are directional. Tire rotation is not recommended for directional tires.
Note: If your tires show uneven wear, ask an authorized dealer to check for and correct any wheel misalignment, tire imbalance or mechanical problems.

Driving with the GYs in colder temps is not a good idea. Could cause damage to the tire, but more importantly you are putting yourself and others at risk as your braking distances in am emergency situation could increase substantially.

If money is an issue sell your GYs and buy All Seasons. If not, keep them and get the Pirelli Sottozeros as mentioned above. Good insurance either way.

[1sgt]

I'm thinking of putting NITTO GEN all-season high performance redial on my 2014 when I get it . I really don't want to spend money on 2nd set of rims . I'm hopping these would be the answer to it it ??

So took the car into Ford. Both front tires cracked. They said I have a few options.

1. Replace them with same GY F1 (not what I want)

2. Buy new FRONT tires, my choice and they reimburse me difference between GYF1 and the tire. I like this, but what to get? Michelin PSS or Nitto 555? And what size? Service guy says upsizing hurts suspension, bearings etc.

3. Wait to see whats on the 2014 GT500 and get those.

Thoughts?

Just a FYI: As a rule of thumb, you DO NOT MIX tire brands or types.

In other words, if you're going to replace the fronts you need to replace the rears with matching tires (not SIZE, but brand, compound, ply ratings, load ratings, etc. etc. etc.).
