Ok, I went to Kumho's website to get the skinny on whether or not 7 inches is appropriate for our stock 17s.

If you go to this website: http://www.kumhousa.com/pages/pass_uhp_712.htm, you will find out that y2kse is indeed correct. 235/45-17 Kumho ECSTA Supras are not supported on 7" rims.

Here's an excerpt from that table: (The ideal rim width is in parenthesis.)

225/45ZR17 7.0 (7.5) 8.5
235/45ZR17 7.5 (8.0) 9.0

y2kse, this is the hard data that I was looking for. It wasn't that I straight out thought you were lying or anything, I just wanted to find some hard facts to back up your claim. That's all.

Spending money on tires that I can't use makes me hesitant to throw them away or spend more money to buy new wheels.

As far as I'm concerned, the argument is over.

 

Thanks, TCm. As between us the argument is over. But I suspect that many others will not acknowledge the facts even when they're staring them straight in the face. So I'll continue to keep an eye out for posts in which opinions attempt to prevail over facts and bring the facts to light. I invite you to do the same.

 

Manufactures give a good safety margin for the tires. a 235 will fit on a 7.0 rim without a problem. Here is a picture of one:

http://www.5thgenmaximas.com/russmaxmaniac/245stock17s/

 

I see no facts except a safety margin. People who have experience tires for years know what a tire can take and where it should end. 235 is perfectly safe. Why you think many professional road race drivers go oversized tires on wheels? Do you see them having any worries or problems? Didn't think so.

 

Thank you for your OPINIONS, Russ. Once again, all you have to do to prove your point is have just ONE tire manufacturer state in writing that it's safe to mount 235/45R17 tires on a 7"-wide rim.

Are you up to the challenge, Russ? Or are we just going to continue to hear your opinions?

 

If someone wants to put 235s on 17x7s let them. Quit arguing about how its unsafe, its getting annoying. NEALOC187 runs 235s on his Maxima(17X7) and does Autocross and roadracing with no problems. Many of the mods you put on cars have liability issues, just look at the sheet that comes with aftermarket springs.

 

OK.Let me try to end this dispute and put it in english.All Y2kse is saying is that no tire manufacturer will back up the claim in writing that a 235/45/17 on a 7" rim will be covered by ANY insurance nor will the manufacturer hold any responsability if a accident or injury should occur with the 7" rim setup.Any of you play golf,ski or go to amusment parks.You do these things but at no time are the establishments(manufacturer) or owners(insurance) reliable if you get injured or killed while not adhearing to the rules or guidlines(Hense the term at your own risk).All that is being said is that if you put a 235/45/17 tire on a 7" rim you are "AT YOUR OWN RISK" and have nobody to blame or sue(not a leg to stand on nor a prayer in hell) if something should occur.Cant we all just get along.

 

Who's arguing, MAX2000JP? The facts are the facts. They cannot be disputed. And I've already stated that what somebody does to their car is none of my business.

Enjoy the ride!

 

Ahhh . . . someone with a grasp on reality. How refreshing!

 

y2kse is the man
If you don't like bruce then you can go suck a lemon and ima kick you in your d!ck

 

Suhweeeet!

 

So, IF I put 235/40/17's on my 7" rims and run a 150 shot of mos through my stk 02 3.5 and while doing a burn out at the red light my tire flys off the rim (and the my motor dies) and kills a bystander at the bus stop I can't blame the tire manufacture?

Of course those in the org with common sense know that the above is said in jest but.......it could happen huh?

SAFETY 1ST PEOPLE!

Can I quote you on that, ssiperko?

 

BTW I went with the michelin A/S Pilot Sport

 

Excellent choice!

 

you may be right, but for your own good, can not go out of specs. This may become an issue of liability. In case of an accident, insurance company MAY look into this, and the guilt will be the one whose equipment wasn't "safe" (within specs). So I'd say, to protect your behinds, do not install a 235x45R17 on a 17x7.0 rim.

 

Kev, it would my absolute honor to have you quote me!!!

 

Thanks for your input, Y2KMaxGXE-R.

Our forum is populated by those who want to increase the performance and looks of their Maximas. I join in that pursuit. On the other hand, there are times when discretion is the better part of valor. One of those times is when it comes to risking safety or financial security for the sake of increasing performance or looks. Mounting out-of-spec tires on our Maximas exposes us to both of those risks.

Whether you decide to run 235/45R17 tires on your stock 7"-wide rims is up to you. Just make certain you understand and are prepared to accept the consequences of your actions.

"An ounce of prevention is worth a pound of cure!"

 

Sorry ssiperko. I'm not Kev. But you're not the first to make that mistake and you won't be the last.

(PS: Kev is a secret admirer of mine. So I know he doesn't mind it when people mistake me for him. Right Kev? )

 

You're right, Russ. They do fit. As a matter of fact, check my sig. I'm running 235/45-17 on the stock rims, too.

And despite all the safety warnings I've heard, I don't think I will be switching tires or wheels, at least not right now. I plan on using that money to go towards buying a house.

In the future, I plan on getting aftermarket wheels and at that time I will make sure they are at least 7.5" wide.

 

Sorry man,

hows this.............If I say it you may quote it!!! Everyone has a right to their own opinion ---- even though it (most of the time it is) may be wrong!!!

ThanX--SS

 

Define "fit", TCm. If by "fit" you mean "falls within specifications", then 235/45R17 tires never have and never will "fit" on 7"-wide rims. And just because something looks like it fits doesn't mean that it actually does. I can put on a pair of shoes that are a half-size too small and they'll look like they fit. But it won't take long before I have to visit my podiatrist. I assume you understand the analogy.

 

Argueing again, don't you ever give up!? GEEZ!

 

Congrats, Russ. You're the first person to ever go onto my official "ignore" list. Have a nice life.

Now is there anyone else who would prefer to mount a personal attack on me rather than face the facts?

Never underestimate the power of denial!

 

Good Y2KESE, people were getting tired of your reposts of your info anyways, so I am glad I got you to block one person. At least I knew I got to you


BTW, straight from tirerack...

Well to support Y2KSE here, are some responses I got from manufactures. I guess he won't see them since he doesn't care.

Here are my responses from different tire manufactures:

-----
The 7.0" rim is too narrow for a 235/45R17 - sorry. We currently do not make a 225/50R17 or a good optional size for your vehicle/rim combination.

Thanks for considering Kumho tires, Frank S
-----
The recommended rim range established by the Tire and Rim Association of America for tire size 235/45R17 is 7.5" - 9.0". Yokohama does not recommend going outside those established TRA recommendations. For this reason, we could not recommend size 235/45R17 for your vehicle as it is equipped with 7.0" wide rims. I hope this information has been helpful. Thank you for contacting Yokohama Tire Corporation.

Mr. Zotz:

The 235/45R17 is an acceptable replacement size for the 225/50R17, with only a -2.3% change in overall diameter, and a slightly higher load carrying capacity.

However, the 235/45R17 is designed to fit 7.5" to 9.0" rim widths. Your 7" width would not be recommended, and could cause tire problems if used.

Russell,

Thank you for contacting our web site. While they will fit the rims, I do not list them as an authorized optional size for that application.

I accept your apology, Russ. You are no longer on my ignore list.

I think it's interesting to note the differences in response between a tire dealer (Tirerack.com) and every tire manufacturer Russ queried. Russ didn't make the point, but it ought to be pretty clear to everyone who you can and cannot not trust when it comes to deciding whether to run 235/45R17 tires on your 7"-wide OEM rims.

In all fairness, however, it should be noted that Russ failed to indicate to Tirerack.com that he was planning to run 235/45R17 tires on 7"-wide rims. Whether or not that would have changed their recommendation is open to question.

Thanks for the info, Russ. FWIW, you've earned my respect for doing your homework and being honest.

 

No problem...

 

AWE crap!!! and i was gonna buy some 245/40/17's and install them on stock 7" rims...........thanks alot, my lawyer was lickin his chops at the though of me loosin control and takin a ride with the emt's.
Seriously though, NICE work RussMaxManiac. 4 everone who even considers doing something so UNRESPONSIBLE this is a great read!
thanks - ss

 

Not to split hairs or anything, Russ did mention to the guy at TireRack that the width is 17x7". It's at the bottom of his email to TireRack.

As a note of my progress with TireRack regarding getting my tires replaced, they are refusing to answer my emails. I will be calling them but I doubt I will get any retribution from them.

 

Thanks TCm. I stand corrected.

A refund would be better than retribution, TCm. I'd suggest you contact your salesperson at Tirerack.com and discuss the information Russ gathered. Once again, if your salesperson knew that the 235/45R17 tires you purchased were for use on 7"-wide rims, he MATERIALLY MISREPRESENTED their adequacy for your application. Frankly, I don't think Tirerack.com has a leg to stand on. And remember, the squeaky wheel gets the oil.
