My car manual tells me what tyre pressures to use for normal driving, and what to use for going over 100mph. But nothing about the fully loaded pressures, and in fact what I’m doing is towing a caravan although from the cars point of view that’s probably similar to fully loaded.
I’d go for the over 100mph pressures except I can’t get above 90mph with the caravan, so I’m not sure...?
I’m dying to know what kind of car gives tyre info for driving at over 100mph but is also built for towing.
Assume there’s nothing inside the filler door? Mine lists pressures for normal, extra economy (at the cost of ride) and loaded up.
'The correct inflation pressures for your car tyres can be found in the vehicle handbook, inside the fuel filler cap or on a plate located on the driver’s door sill. In the absence of special towing recommendations, the rear tyres of cars should be set at the ‘fully laden’ pressure. Where full load pressure does not differ from that for normal driving , the rear tyre pressures should be increased by 4 to 7 psi (0.3 to 0.5 bar).'

That’s the thing - it gives me the default and the ‘over 100mph’ pressures (for ze Germans), but nowhere - not the door sticker or the manual nor the manufacturer website- does it tell me the fully laden tyre pressures.
100mph plus - it’s a Toyota Verso MPV FFS!
Thanks BWD, I’ll just do that.
Go for 36psi at front and 38psi at rear...
Based on nothing other than posting some numbers.
Ok, I’ll go for that on the left. Any suggestions for the right side of the car?

Are you going clockwise or anti-clockwise?
What car? Michelin used to have lookup tables for every vehicle on their website.
I think what you need here is a bit more commitment - 100 is easily achievable if you maximise cornering exit speed and use the hard shoulders to overtake when necessary
It's all in the stw progress guide
There's a table here (linky) for current models (published 12/2017) after the FAQs; add a bit according to the footnote, which only applies to diesel engines, so maybe there is only one pressure (and 100+)
except I can’t get above 90mph with the caravan,
I hope your ATC works ok.
& you don't get nicked.
& if your ATC doesn't work & it all goes tits up, you don't hurt someone else in the process.
(I assume your'e joking obviously 🙂 )

Nobody’s going to get much above 40 on the A82 today!

Not necessarily. It only adds 80 or so kg to the back of the car, mine is rated to something like 500kg load. However what I find is that unless I pump the tyres up the lateral loads are felt a bit more, so it feels less stable. But then I don't have low profile tyres. Generally I pump them to near the tyre max which is about 44psi from 38, which is the same as the recommendation for load.

Most cars above compact size. My ultra boring Passat does 130mph and is quite driveable at that speed because it's made for a European market that includes Germany; and it's a pretty typical towing car. Nothing remarkable about it.
