What is "tire stretch?" Help me prove a couple idiots wrong

I have been arguing with a couple idiots on Audizine about tire stretch.

I am saying that for a tire to be considered stretched, the tire has to be mounted on a wheel, where the width of the wheel is wider than the maximum approved width by the tire manufacturer.


For example, a 265/35/20 has an approved wheel width range of 9"-10.5 inch by the manufacturer.  VVG and lx4life are saying that a 265/35/20 on his 20x10 wheel is a "moderate stretch'.  I say, NO it is not a stretch.  In a 35 series tire, he would have to go to a 245/35/20 (approved wheel width of 8.5-9.5")  on a 20x10 before it would be considered a stretch.


This is a pic of his 20x10 with a 265/35/20

TIRE STRETCH EXPERTS (who have registered at least six months ago and have at least 200 posts)
Is this considered a tire stretch?




Next question...
Is a 255/35/20 (approved width 8.5-10.0) a tire stretch when mounted on a 20x10?

I say NO, not a stretch.  The idiots say YES.


Experts, is 255/35/20 on a 20x10 a tire stretch?




Thanks in advance for settling this for us!!!

Sorry, just noticed I was supposed to post in the New members section first.  Made a post there now to introduce myself.

I guess Im an idiot too lol cause I think it's a stretch. But a mild stretch. Welcome to VSC

agreed. anything that pulls the sidewall at an angle beyond square i would consider stretched.

Cute stretch

Thanks for the welcome.

Since I originally posted, I have found that most people agree with what you say.  It doesnt make sense to me how something within manufacturer specs with no sidewall stretch can be considered stretched, but it appears that I am in the minority.  So, I take back the idiot comment.

Its all good buddy. No need for name calling in the car community either lol. Although there are a lot of idiot car enthusiast wannabes. Especially the know it alls. don't be afraid to ask questions either, you'll get good answers and some bad answers but at the end you'll feel better knowing there's some real smart car guys that don't know everything lol

Thanks man.  I have been modding cars for over 20 years now, with it mostly being Audi's for the last ten years or so.  So, I kinda got the lay of the land.

My latest project is a v10 S6.  Check it out if you have the time...

A 215/35 would've been an excellent stretch on the 10
