A quick search showed that the difference between 111 rating and 109 is 60kg per tyre, with the 109 able to support 1030kg. Four tyres supports max 4130kg therefore, and gross laden weight of F-pace quoted at around 2400kg (depends on spec). Unless you’re pulling 2g or on 2 wheels round corners, can’t see what the problem is! 109 rated all weathers readily available (and was fitted to heavier Freelander 2 as OEM) Am I missing something?

Heatha05, I haven't had any issues with the load rating it is finding tyres of the right size and speed rating. Some that Jaguar show as All Season the manufacturer (at least in the UK) says are Summer only, many manufacturers don't make 255 55 R19 all season tyres at all, at any load or speed rating.

Some of the tyres shown for the US and Canadian markets shown as all season for those locations on the JLR recommended tyres sheet are shown as Summer only in the UK on the manufacturers web sites, so are they different tyres between markets but with the same name or does all season mean different things in Europe than it does in the US and Canada.

I'm not sure where you have been looking, in the UK several makers have all weather tyres in that size listed. Some members have reported fitting Goodyear Wranglers and are listed at £120 plus fitting on Black Circles, that seems a good choice at a sensible price.

The Wranglers aren't available in W speed rating, see my earlier comments regarding speed rating. The Eagle F1 Asymmetric SUV AT is available and is shown on US sites as being all season, but are shown as summer only on the Goodyear UK site. It is also shown as an all season option in the US and Canada on the JLR tyre list but is not recommended as an all season tyre for use in the UK by JLR.

At the moment JLR are not recommending any all season tyres for the 19" wheels in the UK.

Ideally I would like a tyre that matches the current tyres in terms of size as well as speed and load rating, failing that I will consider what is available as an alternative. I was hoping to get some guidance from JLR but so far they are not offering any.

I guess it's a case of perceived liability not recommending all seasons on the FPace which is sold as a sports car not a off roader and different standards apply in other countries. From a practical point of view either fit the recommended winter tyres or take on any potential liability yourself, V rated tyres are good for 150mph so you have a good safety margin on a 2.0D.

Very interesting thread. I have driven a lot in Scandinavia and Germany in winter conditions. I have driven in Sweden on studded winter tyres (the older sort with metal protrusions) and in Germany on winter compound tyres. I have got into the habit of switching tyres in late Oct and early March even living in the UK. It is more of a security blanket for me living in London with perhaps just a handful of slushy days a year but in Germany two years ago and in scotland there was quite a bit of snow and the winter compound tyres really came into their own even on my current front wheel drive Audi. In Germany and Scandinavia you must have the M & S plus snowflake symbol on your tyres in winter otherwise if you have an accident you may not be covered by insurance. All Seasons tyres are OK providing they have the symbols.

I am awaiting delivery of my F Pace which will have 22" rims and there is currently no Jaguar recommended Winter tyre for 265/40 R22. There is a Pirelli Scorpion winter tyre and All Season tyre in this size and I note that Mbadger has fitted the All Season tyres in this size. My question is - if Jaguar don't recommend a tyre type, what does this do to the warranty on the vehicle if you use them? My second question then is, would it be better to get a set of Jaguar 20" rims and 255/55 R20 winter tyres and switch to those in the winter or would changing the wheel spec on my F Pace also invalidate the warranty? Catch 22...

My understanding is that it is not necessary to buy the same brand but owners/drivers are advised to get tyres of the same specification as those fitted by the manufacturer. This is for a number of reasons:

1. You need to ensure the tyres are legal for the vehicle - speed rating, load rating, fit, etc. I.e. if the speed or load rating are below what the car requires then it should be an MOT fail, I.e. H rated tyres (130 mph) on a car capable of 150 mph, irrespective of what speed you normally drive at.

2. The car's balance and stability are affected by changes in the stiffness and flexibility of the tyres and those with the same rating should be similar across manufacturers. This is why it is recommended that owners follow the recommendation of the manufacturer in terms of the full tyre specification. For my 19" wheels JLR recommend 255 55 R19 111 W tyres.

A difference would be between summer and pure winter tyres where it is not uncommon for a lower speed rating to be used than that recommended for summer use. I'm guessing this may be due to the lower stiffness in the tyre walls which presumably would help with grip, I.e. it is also not uncommon to slightly under inflate tyres in snow or ice conditions to improve traction.

I also lived in Northern Germany for 11 years, a few decades ago.

I am definitely not an automotive engineer or expert and the above is thanks to Google, so may also be BS :D

Interesting thing . . if you go on the Velar configurator and spec an R-Dynamic S D180 model (just for example) it comes factory fitted with 19" wheels with All Season tyres as standard. Basically almost the same car as an FP, so doesn't it follow that whatever brand of tyres LR supply on the Velar they'd be just as suitable for the FP...?

Yes Catwoman,
I was thinking the exact same thing.
I read a post in the Velar forum where the Michelin Latitude all season was used in snow with great success so started hunting around for these tyres to see if they were suitable.
It's the same chassis greater weight but same W speed rating.

I have noticed on my search that continental and oponeo do not show the new FPace engines in their drop down so have emailed both to get the corrected information. Continental say they are going back to Jaguar , oponeo said "oh yes well look into this".

I posted further back in the thread the FPace after market choice from topix so here is the Velar after market choice from Topix too

What I find is strange though is the Michelin Latitude Tour HP according to Michelin is a summer tyre
But has homolgation to Landrover.
