Camber vs. stretch?

[nuhhsaxx]

So as far as tire wear is concerened, i have a question.
I am currently running 195/50s on an 8" wheel with 8 degrees of camber.
Now if i were to run say 165/50s and 4 degrees of camber would my tires last longer?

I heard that running more stretch and a smaller tire increse wear.
So basically correct size tire and lotsa camber? Or hella stretched tire and not quite as much camber?

Thanks for any info

stretch and wear dont affect each other AFAIK.

Camber and wear...yes, kinda. People always ask(tell) about camber making the inside of the tire wear faster. My answer to that is no, it makes the outside wear less. Then when they have that poker face, I explain what I mean. And what I mean is the wear is relative to normal. Yes the inside wears more than the outside but not necessarily more than normal. Its the toe that kills tires

I agree camber and toe will effect tire wear. As far as wear, its more of a distribution of force thing. Once one's camber is past zero, the more camber that is added results in less of a contact patch during straight line driving (for cornering, depending on the suspension setup, more camber will increase traction up until a certain degree camber).

Getting back to the distribution of force thing: with zero camber, the weight of the car (downward force) is spread out across the whole width of the tire that connects with the road (the contact patch). An increase in camber will reduce the contact patch and focus the weight of the car (force) into a smaller area (smaller contact patch); so more stress (friction with the road) will be put on the tires more in one area; hence the uneven camber wear.

Now for stretch versus tire wear, it really depends on what one is comparing. The subject of focus for this would be the sidewall and how much it "gives" under stress. for example a 245/45/R18 tire on an 18"x8.5" wide wheel will allow for some sidewall "give" during cornering; kind of like softer suspension. This "give" takes some lateral friction stress off of the tire compound. So without this "give" (say a 245/45/R18 on a 18"x10.5" or small sidewall tires), I would predict that there would be a slight increase in tire wear when compared to a tire with the same tread compound.
