Running 37-38 psi which is the recommend PSI for lightload setting. I’ll try lowering them a bit to see what happens
Replacement tires
Looks like my Eagles are running low, hence considering options.
Wanted to go wider, but front suspension seemingly won't accept anything more than 255 (on 20") without spacers which I prefer not to, especially already lowered.
So out of 255/50R20 with appropriate load rating, the selection of not outrageously pricey performance tires of proven brands is not that big:

- same Goodyear Eagle Sport which I think could have better traction;
- Continental DWS 06 Plus which looks pretty great but still $300 a piece (and I've replaced 3 tires in past year due to punctures);
- maybe some Pirellis (Scorpion Zero ?).

Only on aftermarket rims with lower ET or with spacers, because front strut clearance on 245s is less than 10 mm.You could go with 265/45R20. Minimal difference, I wouldn't even get the ECU reprogrammed. Tire Size Comparison
otherwise yes, 265 would be a sweet spot
Correct. run the two sizes in a good program and compare. I repeat the dealer cannot reprogram the ECU so it is imperative the math is correct and the rolling diameter is within spec. 3% variance is the max. The sticker on the driver's side door regarding the tire sizes contains important information that must not be ignored if one is considering an aftermarket package, or a 19" or 21" rim size for example.You could go with 265/45R20.

In my case my winters are 255/60/R18. I believe Jag recommends a 245 width tire for winters, which is NOT for me based on my experience and comfort level with winter driving.
ok to make this simpler for everyone, any aftermarket rim/tire package or any Jaguar wheel combination that fits a Jaguar F-Pace will also fit the I-Pace.
Categorically.
Categorically.
FYI, 19" wheel options became available with MY21+. Tyre size is 235/60 R19 107V. Recommended pressures are 37/37 for light load and 38/45 for normal load....

wow. 235 is pretty pathetic. That is probably a funny looking car.
In New Zealand the Goodyear Eagles are standard but they just did not seem like the right tyres to me for a number of reasons. Just as they wore out at 25k Michelin released their Pilot Sport SUV. We fitted a set of 265/50/20, slightly bigger but no rubbing.Any of those 3 options should be an improvement over the Eagles, but if I needed a set of tires today I'd probably go for the DWS06 Plus. They're supposed to be pretty good tires, but I've never owned a set. I wish Michelin made a Pilot Sport A/S 4 in this size. That series was my tire of choice for my previous 2 vehicles.
A bonus was that the larger circumference brought the speedo indicator down from the ridiculous 6k over to just 2k at 100kph true. Quieter, grippier (dry and especially wet) and more comfortable than Eagles. I run Pilot Sports on my 3 other ICE Jags and the iPace was transformed just like the XJ12s and XJR were. The Comfort/Dynamic option works really well with these tyres but the Dynamic mode (if driven hard) is more fun for the driver than passengers. Our iPace has done 60,000 km on them, with another 10,000 km still there judging by the depth bars. We have ordered another set.
Unfortunately Michelin will not be bringing their new Pilot Sport EV tyre into New Zealand with the right size for the iPace (too few on the road here so far apparently). It is derived from their racing tyre in Fornula E, but it would be great to hear from anyone on the Forum who can get them.
Interesting ! Can you check how much clearance the new tire has against the strut in the front ? I was under impression that any 265 will be touching it. Same rims BTW.We fitted a set of 265/50/20, slightly bigger but no rubbing.
Agree this is interesting. I thought 265 was too wide also. I would probably opt for the slightly shorter 265/45R20, where Michelin makes a Pilot Sport A/S. This opens up a lot more tire options.Interesting ! Can you check how much clearance the new tire has against the strut in the front ? I was under impression that any 265 will be touching it.

Front strut is clear. But all four wheel well liners need checking because the mouldings are not uniform and a bit floppy and the fittings can be loose. I had to tie a couple back. Best done at home with the wheels off before the tyre shop tells you the 265/50 do not fit.Agree this is interesting. I thought 265 was too wide also.

I wonder if you have the problem described here: Rear wheel arch liner (WAL) may sag and contact the tire...Front strut is clear.

Weird. I just checked and on my still relatively new 245/50/20 tires the speedo is 0.5 mph off at 75 mph ... less than one percent.A bonus was that the larger circumference brought the speedo indicator down from the ridiculous 6k over to just 2k at 100kph true.
My speedo reads about 1 mph low at 40-50 mph with the 245/50R20 tires. My car came from the factory with 18's though which has a slightly larger tire OD. It's still more accurate than the BMW's we've owned. They read closer to 5% low.
The 245/50/R20 Eagle Sports have always been at least 1 mph slower than the speedometer. I believe at 75mph (speedometer reading) I often read that I am going between 73 and 74 mph actual speed. I have often wondered if those running 22" rims with the original 255/40/R22 are running the actual speed since they are turning 692 rev/mile compared to my 704 rev/mile. Just curious.
It has been my experience that Goodyear tires (any size) seem to cause that mph variance. I changed to same size but a different brand for my Range Rover when the original Goodyear tires wore out. It is now reading spot on. YMMV. Some variance will occur during the life of the tires as they wear down.
Volkswagen once got sued because it was determined that they had improperly programmed their clusters, or their supplier assembled the clusters with indicator needles, to always be 2.5 mph higher than reality. This seemed to be another method to get people to have closer to fuel mileage ratings. People driving 2.5 mph slower than indicated would get better fuel mileage than if the car actually travelled the indicated speed.

I've always read that speedometers were designed to err on the side of reading high to avoid accidental speeding tickets. Euro regs specifically mandate that a speedo can't read low, but is within spec if it reads high as long as it isn't more than 10% plus 6 kph ... which sounds like a lot to me. I don't think that there is any reg like this in the US, but our tort system would produce a similar result.
There is no federal regulation in the US for non-commercial passenger cars but there is for commercial vehicles. "The speedometer must be accurate to within plus or minus 8 km/hr (5 mph) at a speed of 80 km/hr (50 mph)."
However, Honda was sued due to 6% inaccuracy in its passenger cars cutting short the warranty period by having the cars reach the mileage limit per the odometer before actually covering the mileage limit. Honda had to extend the warranty by 6%.
There may be local (such as state) laws. Florida has a 3 mph variance limit as an example.
Accuracy does matter when it comes to speeding tickets and accident investigations.

Hi, Do you recall what the original 18" tire size was?My speedo reads about 1 mph low at 40-50 mph with the 245/50R20 tires. My car came from the factory with 18's though which has a slightly larger tire OD. It's still more accurate than the BMW's we've owned. They read closer to 5% low.
This makes complete sense! I had completely forgotten about this... Here in Canada those Pilot Sport 4s would be at the high end of the market for any vehicle but by far the best tire for your money. I'm biased because I think Michelins are the best, period.Just as they wore out at 25k Michelin released their Pilot Sport SUV. We fitted a set of 265/50/20, slightly bigger but no rubbing.

Can you order the tires from a shop Australia or have a set delivered to a friend/relative in Australia or somewhere else local? That is what I would do. Its an extra step to organize shipping yourself but at least you wont have to endure the Goodyears. 60k to 70k on a set is amazing!

Years ago there was a federal <5mph at 50mph, limit on speedometer error. I had never heard it was only for commercial. I had 2 Honda motorcycles. Both had speedometers that read 5 mph high at 60mph. One of them was 5mph off at all speeds (they glued the needle on wrong and the low peg was at 5mph), The other was also 10 mph off at 120mph. (wrong spring)However, Honda was sued due to 6% inaccuracy in its passenger cars cutting short the warranty period by having the cars reach the mileage limit per the odometer before actually covering the mileage limit.
