Newbie- basic Q's on me new motor!

Tbh I don't see the point of expending that effort in a post, to not only offer zero help.. but also just cuss me. Ignored.
The point being chaps..
Ive never had these sort of tyres before. IE slim profile big ones, wider ones.My question again then:
I was asking: if the tyre pressure says "inflate to 51 psi maximum".. would you A) inflate to the max figure, or maybe B) inflate to a lesser figure as a general rule, or C) maybe as its summer, I don't know, inflate to another figure maybe.
And D) taking into account my single odd rear tyre which is "56 max psi".. should I have all 4x psi the same, maybe, I don't know (I shall make an arbitrary guess here as an example) @ 45 psi??
Alas
Hi James.
Even if the info on the side, says 51 psi max-?
Once I know- never need ask again. I just don't ever really like inflating tyres! I get a bit jittery & wanna be sure/ safe (especially my new "sporty numnums" car, the Red Fox
)
The info provided on the data sticker in the vehicle is all you need to abide by, or the owner's manual. Ignore what the tyre sidewall says.
51 PSI is way too high.
36 PSI (approx 2.2bar) is adequate middle ground.
51 PSI is way too high.
36 PSI (approx 2.2bar) is adequate middle ground.
Those tyres will be available for a number of vehicles and the max pressure is an absolute limit, you ALWAYS follow what the plate on the car says. 51 psi is what vans that carry heavy loads need.
I would follow what a few people have said and do 36 psi all round, that way it is a nice balance between comfort, economy and wear.

Tyres are designed to fit a wide variety of cars, which will all weigh differently.
The 51 psi is the maximum pressure the tyre can take, but would only be used on a very heavy vehicle.
As others have said the manufacturer's recommended pressures will.be either on a door pillar or inside the fuel cap. However bear in mind that the manufacturer needs the car to achieve the best fuel consumption, so the recommended pressures will be higher than the optimum for tyre life or ride comfort.
For example the manufacturer recommends 39 psi for my Cupra ST, this gives great fuel comsumption but at the expense of a harsh ride.
My independent garage suggested 35 psi as being better for ride comfort, tyre wear and handling, but I get slightly worse fuel consumption.
Apologies I forgot the pillar sticker has info on it for tyres (I recall I was prompted to look at it before, but for what I can't remember -my memory is getting awful- was it tyre pressures then? I can't even recall discussing this!!).
Great I'll go with 36 then.
I do recall in my old golf4 1.4, that the -firmer- the tyre, the more "crashy" it was. I think. It's odd then that since this low pressure warning in the Seat FR, it's seemed crashier.
I haven't ventured into the "Individual" setting yet, but it would be ideal if I could dial in a softer suspension.. as some of our UK road surfaces are fkn appalling. The A44 west of Leominster I use alot, especially, is car-damagingly-bad: I have to slow to 15mph in a good few sections. The warning lamp started just after one very bad bit with frost dmg & potholes. In strong late pm sun, you can't see to avoid or slow for the bad bits hidden in shadows all over the road. Crunch! You plough thru another shitty bit. Makes me SOO godamm mad. In my new red fox.
Thanks.
You are totally right Zoot in that different brands of tyres can have an effect on ride quality- i have found in my experience that Michelin tyres usually are more comfortable than for example Falken. Best thing to do is read reviews of the tyres you are considering and they should hopefully guide you.
It is possible that the potholes are the reason behind the tyre pressure loss, get them pumped up and monitor them because you may have a slow puncture.
The individual mode allows you to adjust throttle response, steering weight and ambient lighting. For example you could have sport throttle response and red ambient lighting with normal steering weight. It doesnt give any extra power in sport but changes how the throttle reacts.
You may find as the car gets older the ride does get more crashy as parts wear but you could either
1. Changes the tyres to a softer compound.
2. Fit new suspension components
This depends on how desperate you are to change the ride and how much you want to spend.

Many thanks DanMcG.
Aha, presumably the Individual Mode then is "saved"? It'll be interesting to see the throttle changes. But a bit of a shame I can't dial in softer suspension setting. I'm sufficiently brave enough to dive into it then now at least.
It's either the pothole crunch/ warning light re. pressure loss, as cause of the sudden crashy thing happening.. or it's the same as it was & I'm just suddenly super-aware of it.. or as you say, maybe some supsension parts wear thing: I really hope not: I can't afford any more after my recent £300 bill for 2x £35 switches to be fitted. The diesel hike cost has been clobbering enough for me.
Appreciated chaps. Zoot
Found the label thing today, in the fuel door.. seems an odd place for tyre info, but anyway; yes I saw there it says 32 psi for light loads, to 38 psi for heavy loads. Right under my nose all this time! I was looking on the door pillar sticker before.
So I put in 35 psi as a midway. Anyway then saw how to SET in the tyre pressure info, so the warning now dissapeared.
The question does remain though, at what point does the thing decide it's Low Pressure? (I mean if the alarm is set to go off at 34psi.. then this will happen again in a few months). But I don't suppose anyone knows the answer to this.
Anyway, let's see if the crashy thing has been rectified. Quite like the INDIVIDUAL setting: I can choose a sporty throttle, & a normal steering. That seems the best of both worlds, with the steering a bit too 'light' to me, on the SPORT setting itself.
Mind you, the difference are extremely small between NORMAL & SPORT, to me anyway, assuming my Mode thing is working as it should be.
Grateful chaps, much oblidged. Zoot

^^^^ Yes, the 'low pressure' warning may go off in a month or two, as air slowly seeps through the rubber of tyres.
That's why it's important to check and adjust pressures periodically, say, once a month and before long journeys.
Safe motoring.

You can reduce the frequency of TPMS low pressure warnings by doing as @Bahnstormer_vRS has recommended - checking your tyre pressures regularly (doing this monthly and before long journeys is a good recommendation), adjusting the pressure if necessary and then re-setting TPMS to recognise the adjusted pressures if / when you’ve needed to add any air.
I check my tyre pressures monthly, and also do a visual inspection of the tyres for damage and also check the tread depth at the same time. It only takes a few minutes and IMHO it’s much better to be proactive rather than reactive (same with under bonnet fluid levels) and minimises the risk of being left stranded at the roadside because of an issue that could have been prevented by a few simple regular checks.
Our Leon's don't measure tyre pressure directly like some cars do with a small pressure sensor in the tyre. Our Suzuki has this system.
Leon's rely on your wheel speed sensors and an algorithm to try to detect tiny differences in wheel speed to estimate if one tyre has lost some pressure - not the best system, and doesn't work if all 4 of your tyres slowly loose air over time (as all tyres do). Also doesn't work if you have one tyre blow out, well it would do eventually by which time it would be too late.
Basically don't rely on it telling you your tyres need pumping up! and check their pressure regularly.
Yeps, exactly this. I almost learned the "hard way" with my previous car. My Mercedes CLS55 AMG was known for eating up the inner part of the tyres and this caught me by surprise. I only found out about it when I had it on my lift, as the outsides still looked good...
A lot of weight on the front axle and a little camber does this to front tyres (255/30/20). Mercedes is/was known for this btw

This angle clarifies a lot, when steering it leans heavily on the insides of the tyres
