The roads are terrible on the Isle of Wight but the ride in the TDI 4x4 with 19" 225/45 is not bad at all. Running 37psi all round.

Karoq Crater 19" Crater vs. Kodiaq 19" Triglav...

 

Karoq Crater - 235/40 R19...

 

 

Kodiaq Triglav - 235/50 R19...

 

 

40 to 50 profile makes a significant difference.

silver1011, are the above charts screen shots from somewhere? My Edition 19'' Craters are shod with 225/45/R19 tyres, as per Vectis. The link to the Tire Size Comparison website shows quite a significant size difference between the 235/40 and 235/50, whereas the difference between 225/45 and 235/50 is marginal. The reason I'm asking is that I have a set of Sirius 19" wheels which I intend to fit with full winter tyres later in the year.   

 

According to the Slovenian configurator, the supplied tyre size also depends on drive type.

 

On 17" rims you get 215/55 R17 tyres with 2x4 but 225/55 R17 with 4x4;

on 18" rims you get 215/50 R18 tyres with 2x4 but 225/50 R18 with 4x4;

on 19" rims you get 235/40 R19 tyres with either drive type.

Mine are Michelin premacy 3  215/50 18" on a  1.5 fwd.

The Karoq tread width IS 225 mm.

 

 

As you have now gathered 225 is only on 4wd. Either way, this makes very little difference to the fact that 18' on a Kodiaq have a sidewall roughly an inch taller than 18' Karoq, not 5mm as alluded to previously.

Now that we are picking nits, 16 mm actually. https://www.wheel-size.com/calc/?wheel1=225-50-18X7ET45&wheel2=235-55-18X7ET45&fcl=50mm&scl=50mm&wcl=30mm&sr=0mm

 

That was not the point. The point was that any standard tyre fitted on the Kodiaq (and the Karoq too for that matter) has the same rolling diameter, and hence no real difference in how they float over potholes.

I have only ever talked about 18' Karoq vs 18' Kodiaq. Someone said the difference in sidewall is 5mm.  Rolling diameter is irrelevant when there is a variance in the amount of sidewall height (a pertinent metric for ride quality).

 

Now that you are picking nits:

2wd - 215 x 50 vs 235 x 55 : 107.50 vs 129.25 = 21.75mm (granted not quite an inch!) - that's the one I am really interested in as it's surely 90% of the market.

4wd - 225 x 50 vs 235 x 55 : 112.50 vs 129.25 = 16.75mm

 

In neither case the delta is 5mm like someone suggested, is it ? It's either over 3 times or 4 times more - that's the only point I have ever made in this thread as it explains the difference in how both cars on 18's are going to "float over potholes", no prizes for guessing which will have the comfiest ride, assuming the kinematics are set up the same way.

I got them from Skoda UK's 'Karoq Pricing & Specification' brochure (April 2018)...

I guess there are two elements at play here, the cars ability to shield its occupants from the effects of driving over rough road surfaces and the ability of the wheels and tyres to protect themselves from damage from potholes.

 

It's only personal opinion but I think the profile, or the height of the tyre sidewall, plays the biggest part here, hence my preference for a higher profile and also my observation that the larger alloys fitted to the Karoq might be coming at the sacrifice of tyre profile?

 

Given the choice I'd choose a tougher and more durable set-up over handling and aesthetics.

 

The reason I made reference to the Kodiaq is that you seem to be able to get a decent mix of both a large diameter alloy for aesthetics as well as a sufficiently sized tyre profile for durability and ride comfort on poorly surfaced roads.

4x4 version has better rear suspension, so that surely gives a boost in comfort.

^^^ You might well think so, but just go drive them and see, compare, seat of the pant feeling,

it is not always the case that multi link is a boost in comfort for the driver or even gives better road handling, but if you do drive a vehicle at Revenue Weight it can be.

It is a bit difficult to compare the Karoq  multi link suspension from the torsion bar one. Only 4x4 vehicles are built with the multi link rear suspension. At the same time, they have the 2.0 diesel engine. A Karoq 2.0 TDI DSG 4x4 weighs about 200 kg more than the ever popular 1.5 TSI manual gear version.  The added weight is from the heavier diesel engine, gearbox with PTO and drive shaft to the Haldex coupling and heavier rear axle component plus slightly heavier wheels. It would not be silly to assume that the front spring rate and damping characteristics also are different due to the extra weight up front.

 

In essence, the Diesel 4x4 is a different vehicle from a suspension standpoint than the FWD petrol vehicle.

But it has considerably more weight to deal with which is a key reason why the multi-link arrangement is retained. It's possible that the added weight takes away some of the possible benefits of the 4wd kinematics ? But I don't know how much. All I know is the rear damping of our 2wd 1.5 manual works well in conjunction with 17' from a comfort POV.

2WD Karoq and my only critism regarding the suspension is that one road I go down has ALOT of speed bumps and if you take these at any more than crawling pace you get quite a noticeable 'thunk' as you come off the hump as the suspension drops. Never got this in my Octy, so wonder if it's the increased suspension travel, I don't notice it in general driving just over the bloody annoying humps !

I know ithis is an ancient thread but "YES" from me on that one.  If I take a road hump a little too fast then on the exit phase of the hump the front suspension crashes down and sounds like its broken or one of the bushes is knackered.  I took it it to the stealership to check and they said there was nothing wrong.  Another one of those slightly red faced moments (of embarrasment rather than anger) 🙂

 

I run my 215/50 R18's (on my 2wd) at 35PSI as this seems to be inbetween the "unloaded" pressure recommendation and the "Eco" or heavily loaded recommendation in the flap.  I did notice a few weeks ago when it was serviced that the service team did reduce the pressure on all 4 corners (I think if I recall correctly) to 31PSI. Maybe they were trying to give me a hint 🙂   Being the tight wad I am - I popped them back to 35PSI to get those all important extra 4mpg but I do suffer from a bit of lively wheelspin in the damp with the DSG box and the lighter 1.5TSi engine.  Maybe 31PSI is the best bet afterall ??

Interesting that the tables and pictures above indicate 235/40 19 tyres on Crater wheels. My 2021 car has 225/40 19 tyres on Crater wheels.

If I am reading this right - the Type Approval does already cater for that size though so at least that's okay 🙂   the chart was from 2018 so I guess they changed that spec for 2021.

 

I was half wondering if there might have been a new type approval but here it is in black and white (red arrows):
