The fact is THE TIRE MANUFACTURE does not recommend that size PERIOD. FACT!

So what! If they said they will be jumping off a cliff because everyone else does it does that mean you will do it?

Get real. Like I said, find a article, data, that says that its safe to run those sizes on a 8 inch wheel. We are waiting.

Till then, if you ever go to MSR and run that size, make sure you run in the novice group and are no where near me. I don't plan having you loose control of your car at 100 mph due to a blowout.

 

For others that want to reference sizes, here is the list for Hoosier A6 tires.

9-11" rim for 275+ size.

 

Ummm, until the bead wire (actually, cable) breaks, that tire is staying on the rim. Period. It's not rubber that holds the tire on the wheel, it's rubber-coated steel.

Otherwise, you could just take tires off without a machine.

Please come back when you have more than a few events under your belt, and you're no longer spouting the opinions of others (who have about as much seat time as you) as fact.

 

And what stops it from popping off the rim? LOL!

Sorry but I have a ton of events under my belt. There is a reason my car had white letters on my windshield. You know what that means right? Contact Rich at DriversEdge events for MSR.

No opinions. FACT IS FACT. Show me proof that a manufacture supports those sizes on that size rim. I am waiting. Until then STFU.

 

 

on 8" wheels? I agree with another poster: show US a manufacturer that shows an acceptable wheel range for running a 275/285 on an 8" wheel.

 

Face it. Every manufacturer today is out there to cover their asses. They purposefully instill margins into all things in everyday life to cover liability issues.

I don't care that the manu says run a 275 on a 9-11" wheel. Day in and day out people run more tire than is 'manufacture recommended' and nothing to my knowledge has happened to them. Can you list occasions where a tire has blown off a wheel since it was to wide? I think that would be a better argument than using the manufacture rating.

FACT: We have many people on this thread and in the SCCA community that run wide tires on 8" wheels.
FACT: No one to my knowledge has experienced any issues with this in regards to safety.
FACT: You have not shown us specific occasions that have resulted in tire blow outs. and I'm not even talking about 1 occurance. Show us that this is something that happens regularly in the racing community then I'll start to agree with anything you say. The reason I say more than 1 occurance is, hell, with X amount of people running this tire size out there, there is bound to be 1 or 2 people who have had issues. Does that mean it was probably the tire size that was the issue? Maybe, maybe not. But until I can see a trend, a manufactures rating means nothing to me.

The law of large numbers comes into play here. Enough people run it to prove to most of us that this is a common place activity. Until you show us documentation otherwise, byebye.

 

Good thread. Manufacturers do not reccommend fitments that the average tire shop cannot mount nor would they support a combination that is outside of conservative design estimates. Liability is a fact of life and lawyers are not starving.

However, I like the combination of 285/30/18 710s on a stock size wheel. Mounting is a serious b*tch but a friend has the touch and technique. They are so tight on the rims that it takes almost as much effort to take them off as put them on.

I find there is an advantage to the roll that someone mentioned. With little camber in the Z, the tire edge moves flat in the corners and the tire wears evenly. Never had the wheels touch pavement in 2 years and 4 sets but I guess you could with the wrong pressures. I have gotten over 120 runs on a set though they were heat cycled out at 80. Old ones are great for regional events and Test & Tunes. We took the life out of an old set this weekend at a regional. Time to toss them.

The disadvantage is the price of the tires. I'll go through 3-4 sets this year (2 down already). I run a lot of events around the Southeast and the tire bill is getting my wife a bit edgy with me.

I've also ran the Hoosier 275s (A5 & A6) on stock size rims and they are pretty easy to mount. The tire bead is offset in toward the center so they slip on easily. They are fine for 20 runs and then they have to be flipped. Both sets were corded in about 50 runs. A shear waste of money for me.

If I have a point it's that I'm comfortable with my choice just as those that choose to not exceed manufacturer's reccommendations are. Let's go autocrossing and beat some RX-8s.

 

As usual, you have yet to prove yourself like we asked.

 

Amen to that. Time to stop feeding the trolls that think because others have them its the right way to do it.

 

I did, sad part is your ignoring it. I have 18 years of autox experience, and 4 years of Road-Racing experience. You are a college student that barely has any years of experience with no job.

I provided all the manufacture links, and facts. Like I said to the other guy, until you provide proof that its safe from a manufacture standpoint or SCCA/SEB group, STFU.

Edit: I will say that for a AUTOX standpoint using those sizes would be fine. But on a Road-Race standpoint where speeds get extremly high over 100 mph it is seriously not recommended by most people who race. Even the Corvette guys won't do it they say because of the safety issue. Just buy a bigger wheel.

 

I'm a student too. Does that have any bearing on the matter? Why do you personally attack everyone? Neither this nor the g35driver thread had a level of rancor till you joined them both. That seems to be the pattern for you, Russ.

 

Proves your age. Proves that you don't have near the experience us older folks have.



Sorry if your the one that wishes to continue on about this. We await your facts from SCCA/SEB or manufacture. Sorry if I don't like wrong information being given out. I hate for someone to have a blow out and wreck their car and come on here and lay into you or sue you for the advice you gave that was unsafe.

Wow you know my name, seems you know me. Who are you? Pattern for me? lol and you have 17 posts here and you know my pattern. You make me laugh.

 

I'm 32. I never made any claims for which I did not support evidence. I'm generally a lurker and aparently have too much spare time these days. Your tirades are unavoidable unfortunately.

 

Your supported opinions mean nothing. Support it with facts.

 

Support what exactly?

 

OMG nevermind.

 

I can read, thanks. Yes, you provided manufacture links. Fantastic! Awesome! Now where are the links of the cars that have wrecked and horrific accidents that have happened due to using too wide tires??

Since I have been autocrossing for about 4 years now which apparently means I have no experience, I guess you have absolutely no experience in road racing? The people who know me on here know I'm capable of driving. So, until you get your facts straight, which apparently you have not done this whole thread and are only intelligent enough to use the same manufacture link blah blah blah crap as your only argument, you should take your experience and go win nationals or the runoffs on 235s!

PS. Everything else you say is true... I mean, I'm only a college student at one of the top ranked business school in the countries.. Currently I'm working at the largest insurance broking firm in the world, Marsh, and have the potential to make 6 figures out of college, thanks!

PPS. Also, not to say I have an amazing ability at driving, but if memory serves me correctly I was the 2nd fastest 350z driver in BS at day 1 of nationals, although I know that there are many faster drivers out than I, some of which, have posted in this thread agreeing with my opinion.

 

Sorry my facts are straight.

I am done arguing with someone that can't see the light.

 

I was hoping for a rebuttal. You're no fun.

I guess I should just go to bed now, gotta wake up early for my apparently non-existing job tomorrow morning!
