Hi Guys,

Looking to get a new set of treads for my AWD. At the moment I'm running 225/50/R17 on the standard ralliart rims. I've received mixed opinions from tyre shops as to whether 235/45/r17's will fit. The reason I ask is they are a much more common size and hence have a wider range and are cheaper.

By going to the 235's will there be any issues with rubbing or the tyre sticking out, and is a 235 tyre too wide for the ralliart rim. Keep in mind this is an AWD which has a little knuckle very close to the tyre on the rear. Would appreciate opinions from AWD owners specifically.

235 wide tyres are illegal on 7" wide wheels, full stop. IMO, get the 225/50R17 Hankook
Optimo XQ tyres. Way better then the OEM Bridgestone Grid II (in both mileage and grip)
and cheaper too.

..but to answer the question, will the 235 wide tyre fit? Say on a 7.5" or 8" wheel?

Do a search for wheelmaster on AMC to find the link to it. In there. You can specify what
you currently have and what you want fitted. It will tell you how much your speedo is out
(how much smaller/bigger the overall diameter is), how much futher it sticks out or in etc.
Very useful site when buying wheels and tyres.

So is jay walking, doesn't mean half of us here don't do it.

To answer your question I don't think the 235's fit on an awd, I think something fouls on the rear.

when i was looking at tyres an rims etc a lil while ago, talking to the tyre places thier books say that you can fit a 255 under all four corners of an AWD!!
but that is a bit too wide from experiences they have had and dont recomend doing it - only go to 245.

how that relates to your question directly, im not sure, because you have the ralliart rim and i was looking at rims and rubber.
but its something to think about.

sticking out wise tho, it depends upon the offset that the rims have to if they will or wont stick out.
if they do - just get the guards rolled slightly IMO :)

I have no problem with mine

I own a KL AWD running 17x8 rims with 235/45/R17 tyres and have no problems with fouling. And these rims came off my old TH.

Choice is yours!

so long as the offset is correct (+38 from memory) you wont have many issues with fouling the upper control arm on the rear suspension, the FWD have a similar setup i have 235/40R18 on mine atm and no issues here.

235's fit perfectly on an AWD.

I have dunlop Maxxs on.

Work great.

I have the same rims and tyres on an AWD - it looks (and feels) like there is absolutely no clearance (you cannot fit your little finger between the tyre and suspension arm) BUT I have never had rubbing issues or anything else, and it gets loaded up with a lot of gear.

As I said, legally, 235 is not allowed on 7" wide tyres. If an accident happens because the
tyres came off the wheel in heavy cornering, you are out of insurance. Also, most
235/45R17 tyres do not have the minimum load rating for AWDs. Again, if an accident
happens due to overloading the tyres, you are out of luck. Don't forget that because
AWDs have so much more grip, there is a lot more dynamic weight put upon the tyres esp
when cornering.

Tyre manufacturers suggest that 8.0" wide rim is optimum width for 235/45/17 tyres. Minimum width as 7.5" and maximum as 9.0" .
Exception to this would be Michelin Pilot Primacy with 7.5" optimum, 7.0" min. and 8.5" max width rim.

On the other hand 7.0" rim is optimum width for 225/50/17 tyre (6.0" minimum and 8.0" maximum), which happens to be choice for ralliart .

It is annoying and frustrating that 225/50/17 is more expensive and choice is much smaller in that size than in 235/45/17.

It will change soon. Holden is not using 235/45R17 for their 17" wheels. I think they are
using 225/55R17.

Tyre rating,
That is why I fitted the Dunlops on 8" rims.
Rating is OK.

Set of 4 wheels and tryes fitted were $1200 a couple of years ago.

According to dunlop's website, 235/45R17 SP Sport MAXX tyre only has a 94 load rating
and not 95. Check your tyre placard. They don't have an XL series.

With my tyres, there are two versions, ones without the XL badging (93 load rating) and
ones with XL bading (98 load rating).

I fitted the Maragoni Mythos 235/45 17 to my TL AWD, with the 97 load rating. To me this seems logical and legal in terms of size. Looks nice to me and is great to drive.

that is a very much under sized tyre for your AWD. It is 3% smaller (more than the max
allowed). It would not have the adequate load rating as well. I won't want an accident if I
were in your shoes.

VLAD,
Load rating recommended is 97.

My Dunlop tyres are 97 rated.

3% error is good. Better to have the speedo overeading with all the speed cameras around!!

OK cool with the load rating, however, you need to check the rules wrt size differences.

Vlad,
For your education. In NSW the RTA states :-
The outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter
wheel and tyre combination specified for the vehicle and not more than 15mm below the smallest diameter wheel
and tyre combination specified for the vehicle.
I measured the circumference of the new 17" tryes versus a brand new spare. Within 3mm so I am well within the 15mm allowable diameter variation.
Also each tyre has a different rolling radius. E.g a Dunlop will mot likely be different to a Goodyear. Also each tyre model can be different within a particular manufacturers range.
You'll have to look at overseas sites for some of this information.

Yes, I know the rule, it is nation wide.
The tyre/wheel specified for the AWDs (215/60R16 on 16x6 wheels) has an OD of 664.4mm
The 235/45R17 on 17x8 wheels has an OD of 643.3mm
That is a difference of 21mm. Even with manufacturing tollerances, the difference would
still be more than 15mm.

I'm just not fussed. The fitment is to factory 380 wheels. The look is factory. To my reading of the tyre placard speed and load ratings are fine.

The 380s had different standards and its placard will be different to the Magna/Veradas,
especially the 380 GT/VRX ones.
