There is a line between slightly stretched and ridiculous wouldn't you agree? When you can see the barrel of the wheel I believe we have crossed that line.

Herra frush kills the game.

David, you and I both know these guys are more concerned with looks than performance. No argument from me about that

But to argue that the car is suddenly dangerous or undriveable is just plain false

<-Can't believe he is the voice of reason for stretched tire setups

I understand this is a very debatable topic. I'm not trying to ruffle any feathers, just get some info. My car is getting lowered in the next couple of weeks, already on it. Was trying to decide on the possibility of changing the tire setup before I did that. The more research I'm doing the more I am reading about the potential dangers of going with stretched tires. Again, I'm not looking for what I would call an extreme stretch, like this. I do not find this appealing nor what I consider this safe even looking at it.

I'm looking more for something like this, which in my opinion is tasteful, really exemplifies the lip of the wheel.

My 370 is a weekend toy, not a daily driver. I don't ever plan to race it, but if I decided to take a run up into the mountains and I want to open it up I would like the peace of mind to know the tire setup I'm running is not going to kill me.

The top would be probably the equivalent of a 235 on your rear wheel. The bottom would be a 265 by my guess.

Why do you want to go to a stretched tire? Just like the look? Or are you going to lower it to the point where you are tucking the tires/wheels?

as soon as you lower your car you will see that it will completely change the look and fitment of those wheels. you may just end up keeping the tires as is.

as far as clean dressup, my G is about that pict you posted. very mildly stretched sidewall and lowered for a nice clean and fluid look with the arches.

btw, if you want that clean looking sidewall, get the S04's. stay away from DW and PSS with their rounded sidewalls, it wont look as clean.

I think there are many different setups for a Z that can look good. But I really like the look of a mild stretch. As I mentioned above I think it really brings out the entire lip on the wheel. I would never move to that setup if I felt it was going to be unsafe or cause an extreme loss in performance. I don't have any plans to lower to the point of tucking tire, just enough to get rid of that wheel gap. I agree, I think a 265 is probably what I'd be looking for. Just have to figure out if I want to do it or not. Thanks for the input :tup:

Ha, I was just starting to look at other tires for sidewall appearance. Thanks for throwing that out. I'll checkout the S04's.

yah, for some reason 275/35/19 is very narrow for S04, so go with 285/35/19 for the rears. they look :yum:

but then RE11's look even :yum:-er

OP's question still hasn't been answered. I would agree; stretched tires on most (especially a sports car platform) is silly but when talking a very mild amount, it won't be a huge deal.

I had a 255/35 on a 20x10 with a previous car. It was not to the ridiculous and awful looking, tire inside the lip of the wheel because it's so stretched look.. the sidewall of the tire was just simply stretched outwards to fit on the lip of the wheel. 255 was very conservative on the 10" wide wheel in terms of "fitment" or "stretch".

On your 10.5" wheel, you will be fine with a 255/35 but I'd advise taking your front tires and moving them to the rear for the 265 on the 10.5" wheel, if you must go this route. As for the 9.5, I wouldn't want to go any smaller than 235/35 but that is just a mild stretch, as you were looking for.

Sounds like a solid idea. Thanks for your input.

On a separate note... Does anyone here running a wider setup have issues getting pulled all over the road? With my stock setup I didn't have any issues, but as soon as I threw on the 295 R/265 F setup I started getting pulled all over by every little disparity in the road. Feel like I'm fighting the car half the time, which definitely is not as enjoyable to drive. Anyone else have these issues?
