Just a good article comparing lap times with different sized tires. Iirc the narrower tires were faster.

Do stretched tires compromise grip/handling?

No. Basically there is sidewall rigidity, as stated above, hence why drift cars run stretched tires more often than not. Having too much sidewall though, will give you rollover, and will sacrifice grip and stability. Best to have a nice square setup for track.

Why isn't it? You do it on a track :)
I run stretched 195s on a 15x8. Not a huge stretch in most cases but meh. I run it specifically for less sidewall flex.
We are really splitting hares here (lol). a stretched 195 as opposed to a non stretch 195 will probably grip better if you're dealing with like a 70 sidewall. When you get to bigger diameter rims where sidewalls aren't that tall, it doesn't make as much of a difference. Floppy sidewalls make cars shimmy in corners and not retain grip well. The stretch isn't what effects it, the sidewall does. You shouldn't be using 60-70 sidewalls on a track anyway. But if you have to, stretch em. that's probably the only time it's worth it. Even then, you've dumped so much money into rims to stretch them on, get good tires to begin with.
TL;DR get 275s with no stretch, be happy.

You just want to argue with me today :) Despite the fact I'm agreeing with you.
My point is, if you have 195/70/14s as your ONLY tire choice. I'd rather have them stretched than not. It would help you grip int hat situation. In reality, this isn't true and for grip driving, there is virtually no reason to stretch.

I'm not even sure what this thread is about anymore.
I found out yesterday my 245s are too meaty in the rear to tuck even with rolled fenders. Although, I'd fit them if I would take off the 1 inch spacers. But then my front track would be 2.5" wider on EACH SIDE than my rear.

rim

tire
Noun: A rubber covering, typically inflated or surrounding an inflated inner tube, placed around a wheel to form a soft contact with the road.

rims- not the rubber
tire- not the metal
wheels-rubber and tire together as a combo

Stretching the tire takes up the sidewall flex it would normally have, resulting in a more rigid tire. Stretched tires have a lot less give, and are more likely to lose their grip in hard driving situations. But the other side with a straight wall, while having more flex and giving more feedback as to when it's going to lose grip with a more comfortable ride.
Unless you track it, you'll never really notice the instantaneous grip loss that can occur. But it will be less comfortable and more likely to bend/scuff a wheel.
Now, mind you, this is all dependent on amount of stretch too. A mild stretch can be a good thing for spirited driving with a tire that doesn't have a reinforced sidewall. But, those tend not to have the best grip out there anyways.
There are those that will argue tooth and nail that it makes zero difference.. It's the extreme examples that are the worst. But a little stretch never hurt anybody, and is common out on the track when you can't afford higher performing ones.
My thought is, and always has been. Use a wider wheel for what it was intended. A wider tire
