255 tire Auto-x

IGoFast1589 · 02-12-2007, 11:11 AM

If you are running a 255 size tire isn't that better suited for a track than an auto-x? Would that hurt you at on an auto-x because wouldn't it take away from the dartiness of the car?

Um.....NO!!
Its all about grip when it comes to auto-x! The bigger/stickier the tire the better!

Also, a darty car is one that has a good amount of grip!

True a 255 probably isn't big enough but if you were in a different car on say 295's I feel that would affect your ability to turn in quickly.

?

More tire = More grip

With added camber/caster and proper toe, you can only do yourself better with a bigger tire...

From your sig it looks like you would be in STU as long as you go with 245's. You can go bigger if you don't care about that. I ran 275's last year and my only problem was pushing through a corner too much because of the lack of rotation. (and going to fast)

Ok I see thought maybe it would have an affect but apprently not.

it all depends on what wheel it is on.

on a narrower rim the turn in is sacrificed but the added grip more than makes up for it.

on a properly sized rim (at least 9") a 275 has no adverse affect on handling.

it may have adverse affects on your fenders if you're not smart and do it with out research.

You see the reason I thought this is because when you have a wider tire, it increases high speed stability correct? So then while your driving at low speeds, like when your at an auto-x, it would have a more negative affect than if you had a tire that was less wide.

well going from a 225 RE070 to a 255 RT615 i got faster at autox.

Yeah I believe you I just thought maybe it did make a difference. I'd be happy with a 245. Thats plenty of tire for me

there are sti autocrossing with 315 ... Its all about grip... You might ahve a tougher time turning the steering wheel...

TraSTi · 02-13-2007, 05:11 PM

The compromise of Stability Vs Dartiness is more a product of aligment... Specifically Toe in/out...

there is a point where you get too wide.

that point is where the tire can't heat up and becomes partially useless, therefore negating the point of having the wider tire.

TraSTi · 02-14-2007, 05:25 PM

then go softer compound same size.... so really the size is not the problem ...;.. tecnically its the compound... but then there is a point where you can't go any softerl.
