Regular 555's up front right? The R's are pretty good out back. In the 20's, the sidewall should be stiff enough. A little soft on mine out back but not enough to worry. I've pushed mine pretty hard around some turns and they have yet to even really squeal. You should be pleased. Especially when it warms up.

 

Hard to say at this point, only about 25 miles on them total and all of that has been rather pedestrian. I can say that they feel...different, is about the only word I have for it right now, over bumps and grooves, like the driveway or a parking lot, which I know is EXACTLY the description you were hoping to hear from me. Road travel has been relatively similar to the stock tires/wheels, even with the extra inch in diameter. I have driven it in both comfort and sport, but just not aggressively enough yet to really feel what the tires are doing. With it being sunny tomorrow (hopefully), I plan on putting a good 50 miles on it under varying conditions, including hard starts/stops and some fast corners, if the tires build up my confidence enough and if I can get them warm enough. I've heard good things about Nittos from a lot of people, and I'm hoping I share their experiences. This is an incredibly difficult car to get to behave under hard acceleration with the stock wheels/tires. I know everyone has said it, but the torque is just otherworldly. Like I told Gary, I've never experienced anything like it. If the Nittos can tame (or rather, semi-tame) the rear end, then I can let the engine do its job and focus on keeping the front end pointed in the right direction. If these 555's up front don't cut it, I honestly don't know what I'd do at that point. I might be asking for more than the tire--or suspension--can give, and may end up staring an entire suspension overhaul in the face.

But that's ok. I learn more about this car and cars in general every day, and I am finding myself gravitating to the garage even when I'm sick, like earlier this week when it was Wisconsin-cold in South-central Texas and I was putting the new shoes on with a fever. It gives me an excuse to be under the car/hood or behind the wheel, and that's never a bad thing. Er...let me qualify that statement by adding the caveat, "as long as you're not trying to find out what just broke off and came flying out behind you."

 

Post a pic of the bigger tires. The extra rubber will definitely not disappoint.

 

That's good to hear. That's very, very good to hear indeed. Yes, regular 555's up front, the R's are in the rear. My wife scoffed at the "tread" on the R's, and said I get to explain to the cop when he stops me for having racing slicks on the rear in six months that "they came with treads, I promise!!" She can be so hurtful, sometimes.

The sidewalls are one of the things I'm focused on with the fronts, specifically because I don't want the front to push and roll over on the side walls too much. I'm sure you're very familiar with the feeling I'm referring to, and it's a sickening one when you suddenly realize you don't have enough grip to keep your grille from being painted "infield green" or worse, "outfield gravel." You're not the first person to tell me that the 555's up front are an excellent tire for just such a purpose, but you're the first one to do so with a car so similar to mine. That puts a smile on my face. I know the Shelby will push some; it's too heavy, and especially too front-heavy not to. It won't ever corner like a Boss. But if I can reduce the push even just a little bit with the front tires, it gives access to all of that torque earlier in the turn exits.

Looks good. Really wanted to see it from the side to check out the profile. I wouldn't worry about the sidewall rolling enough to cause a big problem. You ain't gonna push your car that damm hard.

 

**** me!

It's not enough I got a $65k car. Now I gotta drop more just to get wheels and tires to make it drive like it should.

 

That's what I'm talking about, not on the street at least. Even with mine bone stock with stock tires you can't push it anywhere near it's handling limit on the street without going to jail or endangering the lives of yourself and anyone else on the road. If you drive it into a turn on the street hard enough to get it to push, you are an idiot or have a death or jail wish. The grip and balance (under normal conditions) is that good.

It feels like much lighter of a car than it is, I thought my SGT handled good and that this one would feel like a pig, but there is no comparison between the two.

 

I pushed mine kinda hard last week around a really curvy road. Pushed it till I ran out of nerve pretty much. And I forgot my helmet was in the trunk and banging every time I went around a good turn. Gotta take that thing out of there.

 

Just don't end up like this guy

 

You're absolutely right, and no, it will never be pushed anywhere near that hard on the street. The track is another story, but knowing the car has as much performance under it as it does, and being confident enough to go all the way down to the bottom of that barrel when the turn is bearing down on you at 100+ mph are two different things. I don't know that I'll ever push the car, under any conditions, to the point that I begin to stress its ability to handle what I ask of it. That's a heck of a lot of money to be slinging around a tight turn at 5mph too much. I think the car is far more capable of handling high-performance driving than I ever will be, and that's probably a very good thing.

Besides, I'm pretty sure if I wrecked it, my wife would ask the car, "Worry about my husband later, ARE YOU OK?!?"

 

I imagine you have some great stories! I played with a younger gentleman who was trying to make the NGA (Hooters) or Web.com Tour a few years ago at TPC Scottsdale (Stadium). I had just as much fun watching him play as I did myself. I am a horrible golfer, but enjoy playing. Keep saying I am going to take some more lessons. Perhaps this winter I may actually do so.

 

Good news today is the sun is out!


Bad news is I'm at work for the next few hours.

 

I was going to take more pictures today, but I took one look outside at the sunshine and grabbed the keys instead of the camera. Couldn't resist a drive.

 

It's been warm enough to drive with the summer tires here, but been very grey and somewhat wet.

 

Well I didn't drive the car today. Just got out of work and the sun is setting.

 

Nice, tempted to put insurance back on the Boss and drive it, but my bill for the last two months has been less than $10, total.

 

I was wondering what the savings would be if I did that? But only 10 dollars in savings?!? I'll keep mine fully insured all year for that pittance of a savings!

 

No, my bill for the last two months has been under $10.

 

I dyno'd my stock 2013 Shelby last month and it was already laying down over 500 lb/ft of rear wheel torque at just 2,000 rpm. Insane! That's torture for tires...and why it's so easy to spin this car in 1st, 2nd and even 3rd. The torque curve on the dyno sheet was almost vertical as soon as we hit the throttle!

 

Headlights don't work??
