Hey,
Just curious as to the load rating for a magna 98. Ive been told its 95 but what happens if you get something with a lesser rating ie 94,93? Also ive heard that a 225/45 tyre will change the speedo reading where as a 225/50 doesn't, is this true or is it just some salesman being a jerk?

Thanks

Yes the load rating for a 98 TF is 95. Although i think it might be possible to get an updated placard from mitsu giving your car a 94 load rating, something that I've heard not 100 % sure if its true. As for wheel dimensions, do a google search or search this site, as there are plenty of calculators out there that you can use to calculate overall diameter, thus working out effect on speedo, for most you need both specs of old (stock) wheel and of new ones.

if u have a lesser load rating then ur placard its defectable and insurance can void ur policy

Welcome. 235/45R17 is almost the same as 225/50R17 for the rolling circumfrence. Loadrating wise, I'm sure it would be 95 but you'll have to check your placard. If it says 94, ask Mitsubishi to check it with your VIN. 235/45R17's have a rating of 97 and 225/50R17 have 94 so the 235's are the way to go if your insurer is happy for you to have a wheel the width required for a 235. My Falkens should be on a 7.5inch but they fit fine on my 7. My insurer didn't care what width the tyre was, as long as it fits. They wouldn't however allow 7.5 wide rims but that didn't matter as I was after the VR-X ones. They wouldn't allow a substandard load rating either. Now, I've fit in with what they've said, but I don't know if it will hold up under scruitineering, not that I plan on finding out.

235/45R17's have a rating of 97 and 225/50R17 have 94 so the 235's are the way to go if your insurer is happy for you to have a wheel the width required for a 235.

Aren't load ratings tyre specific? Not really having anything to do with tyre dimensions, more to do with tyre brand/make?

I'd have thought so but they're supposed to be made to specific standards so they may have to be certain ratings. Dunno. All 225 and 235's I looked at had ratings of 94 and 97 respectively.

The load rating is not solely based on the size of the tyre, but also its construction. Obviously thou the wider and higher the profile the greater the load rating in most cases.

A lot of 235/45 R17 s are only 94 rated. A 235 should be on at least a 7.5 rim. There is a Tyre and Wheel association (or whatever its called) that sets the standards (mating) for rim widths and tyre sizes. If you don't meet these standards you are in just as much trouble with insurance as if you had an incorrect tyre loading. There is probably a reason why Mitsi has a 225/50 on the 17x7s found on higher spec magnas.

In any case a 235 on 7 inch rim doesn't look as good as a 235 on an 8 inch rim. It looks 'balloony'. But each to their own.

I have also heard about the replacement tyre placards for the 95 load rated magnas being issued by mitsubishi, I have not investigated this thou. I understood it was because of the lack of 205/65 R15 tyres that are rated at 95 (most are 94).

It absolutely sucks that a manufacturer can just at a whim make up tyre placards to suit themselves, but we have to go down the engineering path. The tyre load rating should be based on a formula involving 4 passengers at 80kg, 50kg of luggage and the wet kerb weight of the vehicle + say 300kg safety margin giving total load divided by 4.

How the hell can an HSV senator with a DRY weight of nearly 1700kg, and a towing capacity of 2000kg get away with 91 load rated tyres!!!! :mad: :mad: :mad:

Are they? I can't recall seeing any. Anyway, there are standards which have to be followed, (for a reason), and the end result is load ratings and specs which we should follow. All tire fitters should follow the association and manufacturers specs.

You're proably right. Mine don't appear too bad but I'm yet to see a 235 on a rim wider than 7 inch :(.

Yup, we get shafted.

I did. It's not legal.

Yeah thanks for the info people.. much appreciated. Found it to be extremely hard to find tyres with that load rating, most are around the low 90's. Seems impossible to find high load rating 225's apparnetly they need re-enforcing which seems to be to much effort and expensive. Yeh it does seem so dumb how mitsu put such a high load rating on the car. But I found Toyo's 235/45/R17 load of 96 for $175 each which was the only available at a decent price.

Anyone know the effect of using 235/45 instead of 235/50 will have on the speedo. Apparently the 50's have the same circumfrence and obviously the 45's a lil bit thinner. Will this be a big decrease is speedo accuracy or nothing to worry about?!

Thanks

235/45 17 will read marginally faster than actual speed, but you work it out and its only about 0.5km/h, 235/50 will definitely read slower than actual speed. turbo charade posted a link to calculate speed variations!! :) (see above)

Typically a 225/50 or 235/45 tyre will be load rating <95 however if you go for the ones which are marked 'reinforced' they are often quite high, such as 97. You can usually tell how a tyre is going to sit on a wheel just by looking at the sidewall design. I have found that almost all tyres which have the wheel protection flanges will sit quite flat, however ones that don't will get that balloony look.

Michelin Pilot Preceda are one of the very few tyres in 235/45 which are certified (by manufacturer only) to fit on a 7" wide wheel. Ideally I would have bought 8" wide wheels but insurance would not allow it so I am forced to run 235 on a 7" wide wheel, however have not had any problems thusfar. If I could find a 215/50 tyre in 94load or higher and ultra high performance compound that would be the best tyre for a 7" wide wheel.

Are they? Spewing! I looked at Michelin and couldn't work out their stinking website so I gave up. Also thought that those ones would be pretty expensive. Any idea what they're worth? Are they any good? Might look into them next.

Precedas in that size are only around $280. I wanted them but Michelin were out of stock for weeks following their glowing review in Wheels Mag, and I had to get my wheels that week so I settled for the Falkens. Now I'm not sure if I should get the Michelins next time as the Falkens are very impressive.

Agreed. I'm impressed with mine.

Load rating varies depending on brand of tyre. Load rating for magnas are 95, hence causes a slight problem finding tyre to fit. I have 235/45 17's they are kuhmo's and have the required load rating. I know Goodyear F1'a have the right rating also but are expensive. Do not go under the load rating, your insurance is void if you do. Do not get a new tyre placard, you insurance will be void and it's also very illegal.

Keith, you're alive! Welcome back!

Thanks, been a very busy person and haven't had much time for the net but will try to be here more often.

Dude, send me a PM with your e-mail address and I send u an .xls to play with and u can see exactly what size does what. Diameters, speeds etc. Unfortunately I cannot place such file on to this Forum for everybody to view.

Clams: I have 235/45/17 97 Toyo TPG on 7" rims. Recommended rim 7.5 - 9.0. I recently had a claim via Justcar (Magna was broken in to etc - not driving accident) and there was no crying from their part. They could have refused the 3 G claim based on the "incorrect fitting" if they wanted/knew. But they didn't.

Oh, the Michelin tyres might be rated to fit the rim but they've got a load rating of 94 in the 235/45R17 size so aren't legal for most of us.

my rear tyres are dead set as smooth as a baby bum, so im looking at getting some new tyres on the cheapy cheap.

prices of these 235/45/R17 thus far:

Hankook something or other, load rating 97, $139
Simex, load rating 95, $154
Toyo, load rating 97, $155

places reckoned that the Simex were the best value for money, especially in terms of tyre wear

Yeah, crappy stuff this load rating business. I wonder if Mitsu did a deal with Bridge so we could almost only use the Superdooper RE 92 STD rubber... I can smell conspiracy there.
This "fit" stuff is interesting, cos depending on the manufacturer, a 235/45/17 can be fitted to 7, 7.5 or 8 inch rim as per minimum recommendation.
I had an insurance claim few months ago (break-in) and JustCar paid ok - had they considered my 235 Toyos illegal on 7" ROH, they would have gladly bounced my claim (worth $ 3000+). Touch wood, tho....
Also, I doubt it very much that Radar Operators would carry the tyre vs rim specs for every manufacturer with them to bust guys like us.... Eh? Then again - they are known to go to extreme lengths to catch car owners!

So in 225\50's the max is 94 load rating??? anyone found a 95 or higher load rated 225\50???

Where are the toyos available for that price??

No, nothing higher exists.

No, nothing higher exists.
This is becoming a cruel joke.

I own a 2000 Sports model with 215/60 95 tyres on 16"s. The exact same car except bodykit (VRX) has 225/50 94 on 17's.

From what i understand.... i can legally fit the 17x7's from the VRX from both height and width perspectives - but i can not fit the standard 225/50 94 tyres as their load rating is one less than mine?! :nuts:

No other 225/50's have a 95+ rating. :shock:

In order to get a trye with a rating of 95+ i need 235/45's.......which are again technically illegal on a 7" wide rim. :cry:

I could possibly get an 18 inch rim to allow access to more tyres with higher load ratings - but apparently 18x7's are rare as hens teeth and ugly as bat poo. :mad:

Somebody correct me if i'm wrong - but there must be some sort of common sense answer here that can please insurance companies and the RTA? :confused:

My 2002 series II Sports also got std 215/60 95 tyres but my tyre playcard says 94. so i suppose iam on the safe side and i can go and get 94 load rating tyres. :D

May be you can have a look at your tyre play card as you also drive a sports too.

Sweet!! :cool:

Your right it is 94!

My gf has my car today & i couldn't check the placard, so i was looking at info for my car i found on the net that said it was 95. Bloody incorrect!

I called her and made her look for me!!

Great news for me :D - still bad for all those with vurtually identical cars that say 95 :cry:

Great news for me :D
Maybe. That's assuming the placard hasn't been changed. There are some here who think changing the placard makes it legal. I'd say you're car is fine but it doesn't hurt to find out from MMAL based on your VIN.

Got my car serviced at the Mitsu place in Ipswich yesterday. They rang to fill me in on how it went and stuff. Also pointed out that my tyre selection isn't legal. I knew that but was impressed that they a) noticed b) told me.

Changing the placard doesn't help much - RTA etc know the tricks and check them.
Hu? When I was taking mine to LPool Mitsu (not any more) and even had some front end work done under used car warranty they said nothing... and back then I had them illegal 8" ROHs. Where as now I"m more legal with 7". But still on 235s tho!
Just proves how they all differ.
