Hi,

I really like most aspects of my 2017 2.0 DSG Superb Sportline, which I've had 5 years now , except for the ride and the road noise.

I 've already replaced the front Adaptive shocks with Bilstein one's (cost 850Euro ) after only 100,000 KM, that has helped for sure, they are well better than the Monroe's.

But I find even in comfort setting its, too noisy and too rough a ride, very v bump sensitive. I had a standard superb on loan recently and it was way better. Comfort is king! 

I was thinking to replace the rims with 18s (or even 17s prob not as they looks poor) but then was wondering if I could go to a 45 tyre to give a bit more tyre between car and road on the 19s.

Has anyone put a larger depth tyre/tire on the 19inch rim (not larger in the tyre wide - 235 size), I'd be happy to go 225/ 45/ R19 - would that fit?

Seems to be lots of clearance around the wheel.

 

The 40 to 45 difference would be marginal but it might just make it a bit better which would do me, for a zero outlay.

Rim replacement involves messing with the tyre sensors etc.

Any help would be greatly appreciated thanks.

+3.4% in diameter looks too much

visit https://tiresize.com/comparison/

 

as several years tested i can confirm fitment of 225/55r17 instead stock 215/55r17

which gives +1.5% in diameter

+10mm in width

+5mm in height

thx MartiniB,

based on what you say I need to be careful as you got 5mm in height, but the 55 part of the tyre was the same number.

I thought that was the height measurement but the width part seems to also impact it.

Thats a good site - I'm considering the 215/ 50/ R19  based on that.But the tyre width at the wheel may be too thin. 

more investigation needed 🙂

Well sort of. A 225/50 tyre is 225mm tread width and 225/50% sidewall height for 112.5mm wall height. If there were such a thing a 225/100 tyre would have a wall height of 225mm.

thank you, you have definitely given me paws4thot there 🙂. Didnt know that at all, despite all the sites I looked at.

No disrespect meant to you but I wondered if you knew about tyres when you put comfort is king yet you have 19" wheels with 40 profile tyres.   For decades now the fashion has been to have bigger wheels and wider width shorter height sidewalls tyres.  This is the equivalent of wearing a party frock and high heels when you really need to be in sensible clothes (nearer suiting race tracks than our 3rd-world roads).

 

The size of the wheels is primarily to get over the brakes and take fully loaded weight of the car, the tyre size is also about taking the weight of the fully loaded car.

 

The tyres are a very undervalued very complex very important component on the car, they have great effect on the braking, steering, suspension, road holding, ride comfort and noise.  The size of the tyres in themselves in road holding and grip are not that greatly influenced within a the range of sizes the manufacturer offers but more abut the design, build and composition of the actual tyre chosen or compared.  So say a 215/55ZR15 tyre of one make and model could be superior to, and outperform, a 235/40/ZR19 of another make and model.

 

Just for your info some of the sizes given for tyres are nominal, good enough for size comparisons but not strictly accurate, if you look in a tyre manufacturer's catalogue you will see the tyres can vary in size very slightly and things like new tread depth can vary, e.g. one tyre may start with  7-8 mm tread depth against another that starts with 6.5 mm.  That doesn't mean you've been diddled out of 0.5-1.5 mm of tread depth, different tyres wear the tread depths at different rates (though much will be about the car, how and where it's driven).

 

Have a look at the links below to help see the differences in different tyre sizes to your car.  It may help you to know that 80% profile tyres were a standard decades back (and well before that 100%) and 70% was low-profile, and 13" and 14" wheels were standard, 15" for sportier and/or heavier cars (the cars then weren't as bloated and lardy as they are now though, they were much lighter).

 

Have a look at the 'Tyres & Wheels' forum on this site (link below) for all those swapping from larger wheels and tyres to smaller wheels and tyres for comfort (you do not lose  much, if any, handling but it depends on the tyres you choose), you can no doubt also find such threads on this forum.  You can also sometimes see these changes in the 'Wheels & Tyres For Sale' and 'Swap Zone' in the 'Marketplace' section of this site.

 

HTH.

@BennyGil - many many Superb owners with the 19" rims have gone up from the factory 235/40/19 tyre size to 245/40/19 tyre size.

 

It's more comfortable (thicker sidewall), more readily available and hence cheaper.  The Speedo is also more accurate with the GPS reading.

 

If u have DCC, 19s r just as comfortable as smaller rim sizes.

Thx Nta16 , some v useful links there. I bought the car 1 year old (limited edition colour Dragon skin - especially in Ireland) so had to compromise on the wheels. Didn't expect them to be an issue, considered a swap, or new alloys, but want to try the higher sidewall first. Just now need to fix up a crash on a Micra by my son so alloys out. Previous owner decided to not get a back wiper also which is annoying but cant be helped!

Lovely looking motor JR n great to get a recommendation of someone who has done this. I'm going to give that a go on the front shortly. Much appreciated 👍 thx.

Thanks.

 

Please make sure u don't put different sized tyres between the front and rear!!

All 4 must b the same.

Hi,

Before i commit to buying 245/40/19

Has anyone put a larger depth tyre/tire on the standard 19inch (235/40/19) rim (not larger in the tyre width - 235 size), from the guides i read It looks like some other 45/R19 sizes  would fit? Like a 225?, i dont tend to drive on the edge of the handling.

Seems to be lots of clearance around the wheel.

Thx,

Benny

(Apologies for slight repetition)

There's more to the tyre's handling than a width number.

 

Comfort (braking, steering, handling, road holding and noise) will depend on the quality of the tyre, its design, build and materials quality, any decent tyres in 19" size won't be low priced but could be "cheap".

 

You do need to check that a different size tyre will fit and work correctly on your car.

 

Tyres sizes (dimensions) can be nominal and vary very slightly and fit differently even if of exactly the same (on paper) size.

 

According to this "tire" size calculator you get 5 mm (+5.4%) more on the sidewall height and of course (a nominal) 10 mm (+3.2%) tyre width the extra "rubber" may translate to more comfort but there are a lot of variables to consider as to how much.  Having used and unworn brand new tyres should give improvements over used and worn tyre anyway but again this depends on variables.

 

Select a tyre that is good quality and has characteristics and reports of giving a comfortable ride, don't put too much faith in the tyre label ratings and bear in mind with reviews that they not relate to your model and type of driving.   Good luck
