One option, is 215/60R16 tyres fitted to 7Jx16 ET45 rims from the Yeti. However, if you like 225 tyres, then 225/55R16 would fit those rims. 7Jx16 ET45 rims were also fitted to the Superb MK2, but whereas the Yeti used 215/60R16 tyres on this specification of rim, the Superb MK2 used 205/55R16 tyres which have about a 5% smaller outside diameter than 215/60R16 tyres. The outside diameter of 205/55R16 tyres is far too small for the Karoq because the speedometer would over-read by about 10%, ie. 70mph on the speedo would mean an actual speed of about 63mph, and 50mph on the speedo would mean an actual speed of about 45mph, etc. The difference in ride comfort between 225/55R16 and 225/40R19 is night and day. As you can see from the two links below, 16" tyres including new rims can be cheaper than 19" tyres on their own.

To get the comfort of a 225/50R17 from a 225/40R19, you would have to underinflate the 225/40R19 by about 7psi. To get the comfort of a 225/55R16 from a 225/40R19, you would have to underinflate the 225/40R19 by about 9psi. So, if you want a night and day difference from a 225 tyre on the Karoq, go for the 225/55R16 option (although 225/50R17 isn't far behind). In the above chart, I haven't taken into account rim width, and because the 225/40R19 tyre size is normally fitted to a rather wide 8J rim on the Karoq, the difference is even bigger than shown when changing to a smaller rim diameter. Compared to 225/40R19, 225/45R19 increases the gearing by 3.4% so the engine won't pull the gears so well. If you want more sidewall and more comfort, it's probably best to choose a smaller diameter rim size so that the outside diameter of the tyre is still about the same as standard.

The Fabia MK1 1.9TDI 130HP VRS uses 6Q0413031BL sports/lowered ride height front shock absorbers. Bilstein B4 22-196309 front shock absorbers are listed against 6Q0413031BL. The Fabia MK1 1.9TDI 130HP VRS uses 6Q0513025AD sports/lowered ride height rear shock absorbers. Bilstein B4 19-196312 rear shock absorbers are listed against 6Q0513025AD. Some of the Sachs shock absorbers on autodoc are incorrectly shown as compatible with the Fabia MK1 1.9TDI 130HP VRS because they don't have either of the above two OEM part numbers listed against them. Sachs 300032 isn't compatible because 6Q0413031BL isn't listed against it. Sachs 290887 isn't compatible because 6Q0513025AD isn't listed against it. Sports/lowered ride height springs are stiffer and therefore more uncomfortable than standard ride height springs.

The Fabia MK1 1.9TDI 130HP VRS uses 6Q0411105BF sports/lowered ride height front springs which are stiffer than standard ride height springs. The Fabia MK1 1.9TDI 130HP VRS uses 6Q0511115AA sports/lowered ride height rear springs which are stiffer than standard ride height springs.

The Fabia MK1 VRS has 288mm front brake discs, so 15" rims are needed to clear the front brake calipers, ie. 14" rims won't fit. The comfort provided by 185/55R15 fitted to 5.5Jx15 ET40 rims (from the Fabia MK4) wouldn't be far off the comfort of 185/60R14 fitted to 6Jx14 rims.

Front brakes discs on the Octavia MK3 150HP are 288x25mm which is build code 1ZE. It's a TRW brake system.

The Fabia MK1 1.4TDI 70PS has 256mm front brake discs, so how did you manage to fit 13" rims as 13" rims only fit over the smallest 239mm front brake discs?

Does your car have electronically adjustable shock absorbers? What are the OEM part numbers of your original front and rear springs and your original front and rear shock absorbers? Which Bilstein B6 and Monroe shock absorbers are correct for your car? If you contact Bilstein and Monroe directly, maybe they can tell you by reference to your car's VIN number. Maybe these rear shock absorbers are correct for your car, but you would need to check with Bilstein and Monroe directly? I can't see any OEM part numbers listed against the Bilstein B6 20-267537 rear shock absorbers, but there's a long list of OEM part numbers shown against the Monroe C1521S rear shock absorbers, as listed below. Note, that these two rear shock absorbers might not be correct for your car. You would have to check. I'm not sure Bilstein B6 shock absorbers would be ideal for lowered ride height springs. That's normally Bilstein B8, and Bilstein B8 are not electronically adjustable. So if you've got electronically adjustable shock absorbers, maybe go for standard ride height springs? You could always select a slightly stiffer standard ride height spring if you are finding your current springs too soft. Perhaps try two weight range stiffer rear springs? Together with top quality shock absorbers such as Bilstein B6 you should notice quick a difference. Bear in mind, that if you fit difference springs to standard such as lowered ride height springs, the shock absorbers that are correct for your original springs might not be ideal for your different springs.

If I was doing that job, I would also recommend 10 years just to cover myself. Personally, I would go up to 20 years if there's no signs of cracking, no bulges, no cuts, etc. It only needs to last up to 50 miles on the car driven slowly at up to 50mph. If it would pass an MOT, it's good enough for me. And the MOT doesn't fail tyres just because they have passed some sort of artificial use by date. Old bus and HGV tyres have been know to explode when the tyres are over 10 years old, but that tends to be low mileage vehicles that are left standing exposed to the elements for years, not tucked away unused in the boot of your car away from the elements and away from UV rays. It's easy to check a spare tyre because you can view both sidewalls for signs of cracking, cuts, bulges, etc., unlike tyres that are fitted to the vehicle where it's not so easy to check the inner sidewalls, as these are out of sight.

That makes sense, as I doubt there's much demand for all-season tyres in Norway because everyone changes to winter tyres in the winter...often the softer compound "Nordic" winter tyres rather than the "Central European" winter tyres. Here in the UK, most of the winter tyres that are sold are of the "Central European" winter tyre variety because they are designed to work well above 0 degrees Centigrade as well as below, whereas the "Nordic" winter tyres don't inspire confidence above 0 degrees Centigrade and would wear out quickly at warmer temperatures due to their very soft rubber compound. Continental SportContact 7 245/40R19 98Y XL (Euro label C A 72dB) Goodyear Eagle F1 Asymmetric 6 245/40R19 98Y XL (Euro label C A 70dB) Michelin Pilot Sport 5 245/40R19 98Y XL (Euro label C A 72dB)

The need for good grip in 0-10 degrees Centigrade temperatures rules summer tyres out. The below three tyres should all be capable of over 65,000km if you don't drive them too hard, but you would need to rotate them front to back at the halfway point, ie. 32,500km, if the front tyres are wearing quicker than the rear tyres. All Season tyres have the 3PMSF symbol. 3PMSF means that a tyre is winter rated, which means that it has passed a test for good traction in the snow. Don't take any notice of M+S, as it doesn't have a standardised test.

Do you want UHP Ultra High Performance summer tyres or All-Season tyres? In the 245/40R19 tyre size, perhaps Continental, Goodyear, or Michelin. If you go for summer tyres, the grip drops off rapidly below about 7 degrees Centigrade. So if you're going to use the tyres all year round, then using all-season tyres makes sense. If you did get any rubbing with your 8.5Jx19 ET40 rims, then just change to the standard 8Jx19 ET44 rims with the slightly oversize 245/40R19 tyre size. Continental also has a winter tyre in this size.

Many people paid extra insurance premiums because they informed their insurance company that they had fitted winter tyres in the winter, because many insurance companies incorrectly classified fitting winter tyres as a modification. All those who didn't inform their insurance companies that they had fitted winter tyres were still fully insured. I doubt many secondhand car buyers even check whether their tyres and rim specifications are exactly what the car left the factory with. Accidents are caused by drivers, not wheels. So it's a shame insurance companies don't just let you fit what you want. Even in the same size, tyres vary enormously, from UHP (Ultra High Performance) summer tyres to cheap Chinese remoulds. That would make a lot more difference than a small change in tyre size. In the US, they seem to be able to fit what they want regarding wheels, even having the tyres sticking out of the wheelarches by up to an inch. I don't agree with sticking out because that could cause damage to the windscreen of a following motorist.

245/40R19 on 8Jx19 ET44 have been tried and tested by a number of forum members, without rubbing. With 8.5Jx19 ET40 rims, I would try 255/40R19 first by purchasing just just one tyre to try in all 4 positions on the car. With 245/40R19 it's possible that you could get rubbing with 8.5Jx19 ET40 rims, but I wouldn't have thought so, as it's not much different from 245/40R19 fitted to 8Jx19 ET44 rims. However, there's always risk involved when trying a larger tyre, hence the suggestion to try one tyre first. Outside diameter of tyres 235/40R19 670.6mm 245/40R19 678.6mm (+1.2%) 255/40R19 686.6mm (+2.4%)

There's a huge number of cat thefts from petrol cars...perhaps 100,000 thefts each year...and rising rapidly. Extremely expensive to replace if you can even find a replacement (many are sold out because of the huge number of thefts), and the thieves often return for second helpings. For that reason alone, I would go for a diesel. On gentle runs, you could also get about 65mpg out of the diesel so way better than the petrol. Also, diesels don't have annoying spark plugs that you keep having to replace. And diesel engines and diesel turbos are far more durable than their petrol equivalents. Yet another advantage is the better low down torque of turbo diesel engines. No problems pulling top gear at about 1,750rpm for example. This again helps the fuel economy as it's very easy to drive in an economical manner.

Is your steering wheel centred on the steering rack? So although the steering wheel is now straight when driving straight ahead, do you get exactly the same number of steering wheel turns when you go fully left and fully right. Let's say you get 1.75 turns left and 1.75 turns right. That would be good. But 2.0 turns left and 1.5 turns right from the straight ahead position would not be good...and would mean that the steering wheel wasn't centred on the steering rack.

8.5Jx19 but what offset? ET40 to ET44 should be ok. If you fit 235/40R19 to the front 8.5J rim, then fitting 245/40R19 to the rear 8.5J rim will mean that the rear sidewalls have less support than the front sidewalls. So not really a good idea, as you want at least as much sidewall support for the rear rims as the front rims. Many Australian owners fit 245/40R19 instead of 235/40R19 to their Superb MK3s due to it being a cheaper tyre size and providing a little more rim protection...both from kerbing and pothole damage, and that's on standard 8Jx19 ET44 rims. ETRTO approved rim widths 235/40 8.0-8.5-9.5 245/40 8.0-8.5-9.5 255/40 8.5-9.0-10.0

The steering wheel not being straight is a separate issue from wheel alignment. You can have correct wheel alignment and the steering wheel not being straight at the same time. It just means that someone has put the steering wheel on the wrong spline. I've changed front springs and shock absorbers a couple of times, and there's never been any need to do an alignment, ie. adjust toe-in/toe-out. After 30,000 miles the front tyres are wearing evenly and the steering feels as good as new.

Nigel, let's say you had a Fabia MK3 with 215/45R16 tyres, and you wanted to put a 185/60R15 spare tyre in the boot that didn't come with the car when it left the factory, as let's say it only came with a puncture repair kit. Would you contact your insurance company to check if you needed to pay extra for carrying the non-standard spare wheel (just to be on the safe side)?

I'm not surprised it was hard work. You can't a rational conversation with someone who doesn't understand tyre sizes and rim specifications, ie. the wheels. Does your insurance company even know what your standard tyre size is? So what happens if your car comes with 225/45R17 tyres as standard but you want to use 205/55R16 winter tyres in the winter? In this example, let's say that 205/55R16 is the only size that is approved for the use of snow chains.

All UK insurance companies are governed by UK courts. That doesn't leave them room to deny cover on the basis of an insignificant factor.

Some Superb MK3 owners upgrade their standard 235/45R18 to slightly oversize 245/45R18 using the standard 8Jx18 ET44 rims, as shown in the below thread. Slightly oversize 245/45R18 on Superb MK3

I think you will find that it's not about whether something is a modification but whether something is a "significant" modification. After all, if a modification is not significant, it's not going to affect the insurance group of the car. When I phoned my insurance company the main thing they seemed to be concerned about was that you didn't increase the performance of the car. They also said that changing to a one size different tyre size from standard was not a problem. When you buy a new car, you might be able to choose from a range of tyre sizes, and I'm not aware that choosing 225/40R18 over 205/55R16 for your factory build increases the insurance group of the car, where all other things are equal such as engine and trim level, etc. As you can see in the ETRTO chart below, 205/55 fitted to a 6.5J rim is perfectly normal, so I woudn't regard that as a signicant modification over fitting a 205/55R16 to a 6J or 7J rim. Also, if Skoda had been selling the Superb MK2 with 205/55R16 tyres fitted to all of the allowable rim widths, ie. 5,5J, 6J, 6.5J, 7J, and 7.5J, the insurance group would be the same for all cars providing all other things were equal. ETRTO approved rim widths 205/55 5.5-6.5-7.5

The below rim sizes are shown in the Skoda parts catalogue for the Superb MK2, except for the 6Jx16 ET50 and 6Jx17 ET45 winter tyre size rims which are shown in the owner's manual for the Superb MK2. Superb MK2 standard tyre and rim options 205/55R16 6Jx16 ET50 (winter tyre size) 205/55R16 7Jx16 ET45 205/50R16 6Jx17 ET45 (winter tyre size) 225/45R17 7Jx17 ET49 225/45R17 7.5Jx17 ET49 225/40R18 7.5Jx18 ET46 This is the only 7Jx17 ET49 rim that I've seen in the Skoda parts catalogue.
