Too narrow or too wide of a tire on a given rim is not good for handling. I would rather be on the wide side than the narrow side. The streched sidewall deal that people like right now is horrible for handling.

That's also not 100% correct. Too narrow (within reason) will almost always perform better than too wide. A 275 on a 8" wheel will deflect a lot in turns, whereas a 225, a bit too narrow won't budge in a turn.

While I see that you like to try and correct me. I have owned and raced 7 BMW's and a few were ///M cars, I understand handling and tires more than I could type in a paragraph. I used to do the rolling diameter calculations just for the heck of it with the formula memorized. Sure a 245 Kumho MX or Bridgestone S-03 will run wider than say a Dunlop SP Sport 9000 or Kumho Exsta Supra 712, but my above recommendations are damn close to spot on.

I realize you're a domestic owner at heart, and I...well...hate the damn cars, barring the Vettes, a car that can actually perform ALL AROUND well, and not be built like poo. But there's no need to argue with me on common sense things. A 245 tire will always perform better than a 265 on a 8" wheel, it fits the wheel correctly giving more precise handling. And no, I don't run euro stretched tires, just CORRECT for the wheel, that's all.

maybe Autox is a different animal.

but I've pulled better times with my 275/40 on a 8" wheel then i did with a 245/45 on an 8.5"

same car just different wheels/tires

and the 275s were more worn.

I understand that Proper size is key to optimal handling but stating that it will "ALWAYS" perform better isn't true.

the 275 on an 8" wheel isn't ideal but when restricted to 8" for either $$ or class purposes it's better than a small tire (assuming it doesn't cause any other adverse effects of rubbing, breaking things, not heating up enough yada yada) (when talking about autox).

i refer to Autox b/c that's what I know, i'm not a road racer (yet ;) ).

Russelt3hpirate is absolutely correct. There is no "absolute" answer here. Saying a 245 will always perform better than a 265 is just incorrect. I have seen and experienced many times that wider is generally better within acceptable limits. There is a correct range of tire for a given rim.

Your sizing list is accurate, but by no means is it the end all be all when performance is concerned. You can go wider with success if you have the ability to do so. Do you need go to the absolute limit on a Yaris for maximum performance? Probably not.

What you have owned and raced are irrelevant to this topic as are rollout calculations you have memorized. No offense, but just because you have driven a BMW around a track dosen't mean you are any good at it, or that you are some supreme source of automotive knowledge. If you are wrong, you are wrong.

Let me hit some of that good shit you are smokin.
I have been doing tires since the day I turned 18, and I can state fact and back it up to disprove everything you have stated above....
let me hit that good shit one more time

BTW... I geuss you think my 225/50VR15 handle and preform like crap because they are "too wide" for the wheel and skinnier is better.... I can out corner a stock yaris all day everyday
