about 5 months ago i bought some wheels for my car, 17x7 ROH furys. and they look sweet. But after reading stuff on these forums i am worried about the rubber they put on them. They are 235/45/R17 93V. From what i have read i cant have 235's on a 7" wide wheel and the load rating isnt high enough.

The guy said its all fine when i had them put on but im not so sure now. Are they illegal, would insurance still cover me, and could i make them swap them to a different tyre or would they charge me for it?

i have a TE by the way

According to the Tyre & Rim Assoc, you can't legally have a 235/45/17 on a 7" rim.

Also check the sticker on the door panel which will tell you the minimum load rating you need. On the TJ its 94.

I would go back and have a word to this tyre place.

it should be a 225/50/17 but the 235 will be fine. we put that size on 7" all the time, there is no problems, but the only tire you will find that meets the load rating is a goodyear eagle f1, i work in a tyre shop so i should know this

it should be a 225/50/17 but the 235 will be fine.

Unfortunately legally it's not. If you have an accident the insurance company has a right to refuse the claim as the car is unroadworthy. The TRAA sets these standards which apply across Australia.

If the tyre place misled you then they must either fix up the problem or refund your money.

Are you sure a 235 will be fine, please dont give an answer if your not 100% sure. I dont want to find out after iv crashed (if i was to crash) that they are illegal. Thanks for the quick answers though!!

Sorry man, but the Bridgestone Grid II's, Potenza GIII's and Dunlop LM702's and Pirelli P6000's all come in 225/50/17 and have a load rating of 94. There must be others.

u wont have a problem with insurance, chances are it will look a bit odd but legally you shouldnt have a problem, but if u are in doubt dont ever take anything said on the internet for serious

sorry, i was looking at the wrong thing, goodyear revspecs and rs-02s. thats with 94v and there is plenty more with 94w

They're not legal. I would take them back and get them replaced. Being from a Tyre Shop they should know it is illegal. If you ever got into an accident, you could sue them for putting wrong tyres on.

alright cheers everyone for the responses i might go and chirp them about it, see what they say.

I spent the morning looking at wheel and tyre packages for my VRX. Ideally I wanted 17x7.5 with 235/45/17 tyres. Most of the wheels I liked (not many) didn't come in 7.5 width. It is either 7 or 8. I figured the 8's would run more risk of scraping something, so I concentrated on the 7's. However, when I told the guys that 235/45/17 wasn't legal on a 7" rim they laughed at me. They said they've been fitting them for years. That was Jax, Beaurepairs, Bob-Jane and a couple of independants. All said the same thing. I told them to look in "the book". They all pulled out the same guide, that showed that a 235/45/17 was not specified to fit on anything smaller than a 7.5" rim. Some of them conceded that they had never looked it up before and some of them even said the book was wrong :bowrofl:
So I was faced with either using the more expensive and harder to get 225/50/17 on the 7" or getting 8" rims with the 235/45/17.
I rang NRMA and they said they didn't care about wheel size (as in 17 or 18 or 19 inch) or even what tyres you put on it. All they cared about was that on a TJ Magna, the widest wheel they will 'allow' is 7".
So that narrows it down, doesn't it :cry:
All I can 'legally" get and be insured as well, is 225/50/17 on 7" rims.
Back to the shopping list :sook:

hey birdman.. ta for clearing some stuff up for me also - i asked nrma the other day what was the max width for me, they said 7".. thats fine...

also when i go get new rims fitted.. they include tyres in the package...
are these packages any good - like decent tyres? im not sure what "225/50/17 " is 9liek twhat the numbers mean).. care to elaborate? i dont want to breech insurance policy :D so what type of tyres would i be looking at getting that would be insurable and roadworthy...

(ive got a TE)

Edit*: just curious... does nrma like to go above a 17" on a TE? i forgot to ask...

ok I'll just add what I was told by nrma insurance around a year and a half back when I got my rims. Basically they would allow you to go 2" larger than stock (magna advance comes stock with 15 so 17 max on my model and I had to stick with 7" width) this really narrowed me down in choices. Unfortunately at this stage I hadn't been warned about tire load ratings and legalities of 235's on a 7" rim so now i'm having to look into it all over again.

To quickly explain the naming convention on tires for you take the "225/50/17" above for example. 225 is the width of the tire, 50 is the ratio of the height of the tire to the thinkness (this is where you will often here the term low profile) and 17 is pretty obviously the wheel size

Dee,

225/50/17 means 225 mm wide, 50 means the ratio of wall height to tyre width ie 50% (the lower the number, the lower the profile) and the 17 means the wheel size it will fit (in inches).

So the 235/45/17 tyres are a little wider but a slightly lower profile. When these tyres are put on the same width rim, the wider tyres will 'balloon' out a bit more than the 225/50/17 because they are wider. When you increase the tyre width on the same size rim, you must lower the profile (ratio) so the overall rolling diameter of the tyre is preserved. If it isn't then your speedo will not read correctly.

Now I don't know the reason why the 235/45/17's are not legal on a 7inch rim. Maybe that little bit of ballooning is enough to potentially rub on your struts.

I think I will just get the 7inch wide wheels and shop around for some deals on 225/50/17 tyres.

What ur saying BirdManVRX about an 8inch rim and tyre package rubbing is not true.

Take a look at Cummins Ralliart or Booya's car Booya is running if i remeber 9" or 8.5" and Cummins is running 8" at the front and 9.5" at the back.

so there is nothing wrong when fitting 8" wide rims just the fact that insuracne is less likely to insure you.

Tom

can someone please tell me what tires they have on their TE to fit a 17x 8 inch wheel and have a load rating of 95. Im finding it pretty much impossible to find one that is a resonable price. (or anyone that works at a tire shop might be able to help me out aswell. I need the model and stuff.

\thanks heaps

So the 235/45/17 tyres are a little wider but a slightly lower profile.
235/45R17's and 225/50R17's share the same profile height.

Yup. I'll explain something further on *

People, here's what you need to consider when looking at rims and tires.

a) your tyres must conform to the tyre placard issued with the car from the factory regarding load rating
b) your tyres must conform with the tyre and rim Bible regarding fitment to rims
c) your tyres and rims must conform to your local authorities regulations for roadworthy acceptability *
d) your tyres and rims must conform to your insurance companies regulations

Failure to observe all of the above allows your insurance company to void your cover in the event of a claim.
* Manufactures list their rolling circumference so you can stay within the tolerances dictated by your local road authority to keep your speedometer within an ADR tolerance.

Here's a couple of situations which you must be aware of.

You purchase your new Magna from a Mitsu dealership and it has 18 inch wheels on it but that model only had 15's from factory. Chances are, it's unroadworthy. If it had 16's then you're probably okay. If it had 17's then the tyres probably don't match sit within the rolling circumference tollerances.

Tyre companies for the most part don't observe the tire and rim Bible, ask Killer about his episode. Don't worry, Magna's aren't the only vehicle that get the problems. Commodores and Falcons also have some issues but not as wide spread. You are responsible for your car so choose your tyres and rims carefully.

Swapping your tyre placard is illegal and won't mean jack come claim time when your insurer takes your VIN to Mitsubishi to see what it should be.

Most insurance phone monkey's know very little about technical specifications and what their company actually covers. Ask to talk to one of their tech staff.

Falken have 235/45R17's that will conform. Your problem will be that an 8 inch wide rim probably isn't legal by either your insurer, local traffic authority or both.

Other non-mainstream insurers are more flexible but still usually need to conform to some level of roadworthiness hence Booya having 19's which wouldn't be legal / insurable normally. You need to discuss this with one of their staff.

Toyo Tranpath in 235/45R17 is 97 load rated. Most tires in this size will be labelled as REENFORCED if their load rating is higher than 93-94.

235/45R17's and 225/50R17's share the same profile height.

235 * 0.45 = 105.75
225 * 0.50 = 112.5
215 * 0.50 = 107.5

The tire should be 215/50R17. You are allowed to change your overall diameter by no more than 15mm. So a 225/50 will still be legal (it comes in about 11mm larger) but your speedo will read about 1.5% out which isn't huge :).
