it can accept but super ugly, and rim very easy to scatch, not only that its dangerous, if puncture cos the tyres is stretch to the side,  when puncture the risk of tyre dislodge from rim is higher.

it can be accepted when u got no choice. u got no option.

but if u are a paying customer, and u not in a hurry to change at once, why would u compromise on it?? 

 

WELL SAID ,

tires manufacturers claimed is acceptable meaning can fit.

they do recommend Idea or optimum size matching.

tire and Wheel matching is a Technical and Safety issue not Cosmetic or Appearance.

please be a Wise consumers .

thanks for Sharings

Different brand of tyres with the same "official" width, may not end up having the same width after inflating and mounting.

Both are "205" but you can see the difference. Some tyre manufacturers declare the inflated tread width. For example, on the right is a 205/50R16 RE71r, after inflation is 8.4", which fits a 16x8 rim. 

Left: 205/45/17

Right: 205/50/16

Wow you actually went to  stack them up and take a picture.  Thanks!

 

But one point,  the 16" are fitted  on 8j rims? I think 8j is too wide for 205 tyres. And are the r17 rims 8J as well ? the wide of 7j and 8 j is one inch difference, I am sure it makes some diff to the overall fatness of tyres

The photo is what I got off the Internet when I was at work. I took one tonight, of my own tyres. 

Ventus TD on the right, 195/55R15, 35"

Michelin PS3 on the left, 205/50R16, 34"

When inflated, the section width varies with manufacturer and type of tyres. I cannot find the specs for Ventus TD and got something similar instead, Proxes R888. For a 15" 195, the section width is 7.9", meaning it can cater up to a 7"-7.5" width rim and not look stretched. The side-walls are also super hard. Eco tyres of the same dimensions would look different mounted on the exact same rims.

225/50/R17(656mm overall wheel diameter)  is only 1.1% smaller in total diameter from 215/60/16(664 mm wheel diameter).  If you change to 215/17, that will still give you 0.6% larger diameter than the original. You will not be able to  find the exact diameter once you change the rim size. Visually, no one could tell the diff among the three. 

What did your agent say is wrong ?  is he referring to the offset that is wrong or the wheel size is wrong ? 

What is the original offset? 

did you ask the agent what should the correct size ?

he should not just say wrong and walk away.  Dont panic, go clarify with your agent. 

On 8j vs 7j, 8j fits 225 nicely, whereas 215 fits 7j better. both 225/8j and 215/7j are correct.   

Lets hear from other bros. 

 

 

Hi,

 

To be exact, the wheels are protruding out too much. 

Agent clarified that 215/55/17 will be acceptable, but not 225/50/17.

Factory rim offset is +55, but I was sold +42.

Actually 225 fits 7.5” very well, in terms of visual appearance. And 215 for 7”. 8” with 225, Stretches the tire by that’s wee bit to make the sidewalls a bit straighter and give slightly better handling. 
Stock is 215/60/16 with 7x16 et55. With 8x17 et42, the wheel face moving approx 26mm outwards or approx 1in will make it more flush with the fender. 

i think the tire options on 225/50/17 are more performance oriented than 215/55/17, which is the recommended specs. I wholeheartedly agree with what Stamford put on. 

Yes you are right. On 8", my 225 seems a bit stretched.

No doubt it's more performance oriented but I did emphasize to follow manufacturer's setting and I emphasized 215/55/17 a multiple times..

For this car, if I am looking at performance, I would have went for 225/45/18 and given even more options of rims.

The only reason I am upgrading because 16" is too puny.

End up, not only I am facing a harsher ride, slower pick-up, I had to face the challenge of wider u-turning as well as a drop of fc.

 

I was also upset on the hard selling and not delivering me what I asked for (multiple times). I was too kind and trusting to walk away without checking.

Nonetheless, I have visited another branch and they have amicably resolved this issue for me.

215.55.17 is more accurate then 225.50.17.

  +0.4% dia vs -1.1% in dia

frankly speaking, its very very small different. but given that your rim is 17x8 u got no choice other then to use 225 width tyre.

in fact i feel 17x8 should use 235 already .( but 235 width tyres for 17' rim is extremely rare and odd) so for your rim 225.50.17 is the best choice

generally i feel

17x7 for 215

17x7.5 for 225

17x8 for 235

 

 I have settled for 17x7. Still insistent on 215 😂

Yes, 225 on a 7jj may make a tyre side wall looks rounded also.

Anyway I dont know why the agent said was wrong, some of these SAs are clown, or maybe next they will say warranty void 😤😤

Honestly, this SA I been engaging with for 10 over years.

Nope, warranty will not be voided, he assured me this and I have his words.

It is indeed wrong as 215/55/17 is factory approved.

The reason why he flag out to me is because the wheel is protruding out too much. Else, he also won't notice anything.

Relax bro - this small difference is very insignificant.

Most important is there is no rubbing on the fender when you do a full turn (Either left/right)

You can always change to another tyres spec when this set worn out. 

Just felt cheated. Nonetheless, had the rims changed to 7".

But i will finish this sets of tyre first. Maximum another 10000km to go. Continental not cheap 😭

That's a very good picture.

Can I ask for the (left) 17", is it inflated to any rims?

seems like performance tyre are more 'wider' in the same width regardless.

bro naimed also have his performacne tyre wider.

Factory rim offset is +55, but I was sold +42.

So the problem is the offset , not the tyre size. The offset of +42 from +55 caused the wheel to be extended out by13mm, plus your wider 225(5mm more from center line), total is 18mm further out from the original.  Fuel saving and comfort won't go with wider tyres but with that 10mm increase in tyre ,   the difference can only be felt in the heart,  not so much on the actual outcome. Since you feel larger turning radius, higher fuel consumption , harsher ride and slow acceleration after changing tyres  it is best you stick to original to save the anxiety.

good Evening 

wheel protruding is mainly because of the Wheel width and Wheel Offset , is rather common to see this on the road especially the Front wheel of Front Wheel drive vehicle (your HRV is one typical example) and you can see this Honda be HRV or Vezel (they are 99.99% same car)in any car park .

Be a wise Consumer , next time do highlight your expectation when you are looking for ang change of  wheel.

happy to heard you have solved your issue

glad you fix the issue. didn't realize it was protruding. i thought even with the large vezel /hrv wheel well it should be more or less flushed. offset is wrong then.

Actually although flush look very nice, some time it will touch your fenders, esp when u got full load u go over hum slightly harder abit.

then u see your tyres got lines from cut at the sidewall. even more so if your tyres size is slightly bigger .

but its very hard to have best of both world, when u modify🤣

They are mounted on stock Mazda 17x7 rims. The 16" tyres are mounted on Enkei RPF1s 16x8.

So its actually the 16" tyre on 8jj that mades it looks thicker than the 17" tyre on 7jj.

But I see your point that even if both are on the same jj the 16" will still looks thicker. Seems more evident on sports tyre with hard sidewalls.

just stick to Original size or Original factory recommended optional tyre size if your car not Sure or In doubt
