tires and led lights

[habo]

Good Evening


Tires, which do we prefer 93 or 97 XL? to a C4 Grad Picasso?
Now it wears 97 XL just like when I got the car, but I was wondering if the 93 has softer sides and so I have less noise from the rear.

Has anyone installed low beam philps led lights? do we need canbus adapters?

I have fitted Philips Ultinon Xtreme LED H7 bulbs in our Peugeot 308's dipped beam. They do not cause any warning lamps or messages on the dashboard but they do store errors in the BSI. Maybe canbus adaptors would stop these errors but as they doesn't seem to cause any problem why bother?

Philips have introduced lower cost LEDs in the last year or so and I don't know how those behave.

Surely these are still not road legal to install into Halogen lamps....

Paul-R thanks, a friend put the Philips H7 Ultinon Essential Led 12V 24V 20W 6500K in a C4 model 2013 and they are fantastic, they did not need adapters and we tested at night, I drove against it and saw that they do not dim (but they were perfectly adjusted ).
But I would also like an opinion from someone who has put in GP.

GiveMeABreak I know they are illegal just here in the (-expletive removed-) where I live they are full of everything, cars and tractors with Chinese leds, which shine wherever they go. It's a war and I have to defend myself.

Does anyone have an opinion on the 93 vs 97 XL tyres?

Be aware - now not legal for MoT - at all. Also tyres over 10 years old.

I live in Greece .
I change tyres every 33,000 miles or every 4 years , about

I think Greece is still in the EU last time I checked and the same law applies, so be aware if you have an accident and are caught with them - insurance may decline to pay as an illegal mod..... Your choice, but we don't condone it on the Forum.

As much as my lights are dreadful in the Aircross, the first thing I did was upgrade the bulbs to road legal brighter halogens. I know I'll get a shorter life span out of them, but at least they are brighter than stock bulbs.

To clarify for anyone wondering why all the fuss about LED upgrade lamps - one of the main issues is that road use approved halogen lamps all have their filaments in the same position. An H7 lamp made by Philips will have its filament in exactly the same position as one made bt Ring as one made by Osram. Headlamps for use with halogen lamps will have their reflectors designed to utilise that filament location. LED lamps can have a somewhat random positioning of emitters which can wreck the headlamps beam pattern.

I'll just quote the updated Rules March 2021 here in the UK:

Current

Section 4.1.4 of the current MOT inspection manuals for both motorcycles and cars and passenger vehicles states ‘Existing halogen headlamp units should not be converted to be used with high intensity discharge (HID) or light emitting diode (LED) bulbs. If such a conversion has been done, you must fail the headlamp.’

Changes:

From 22 March 2021, we’re changing these rules so that not all motorcycles and vehicles will fail the MOT test if their halogen headlamp units have been converted to be used with HID or LED bulbs.

Class 1 and 2 motorcycles

Class 1 and 2 motorcycles must not be failed for the defect ‘Light source and lamp not compatible’.
Headlamps must comply with all other requirements of the test and headlamp aim.
The motorcycle inspection manual will be updated shortly, and the ability to select the defect within the MOT testing service will be removed.

Class 3,4,5 and 7 vehicles

For class 3,4,5 and 7 vehicles, the defect ‘Light source and lamp not compatible’ only applies to vehicles first used on or after 1 April 1986.
Should a vehicle be presented for an MOT test with conversions before 1 April 1986 they must not be failed with immediate effect.
Vehicles presented with converted halogen headlamp units first used on or after 1 April 1986 will continue to be failed.
Headlamps must comply with all other requirements of the test and headlamp aim.
The cars and passenger vehicles inspection manual will be updated shortly.

bobins are both right and wrong. OSRAM has started the process of certification of old car models with led lamps
Here are the ones that have been certified so far that they can use led .https://www.osram.com/am/campaigns/vehi ... /ledcheck/
So there are halogen reflectors that can accept led.
It is a matter of money to check all the old models. And if it is certified and legal in Germany it is legal in all EU countries.

An opinion on tyres; has anyone put in GP 93 load?

Not correct - see the small print in your own link Habo:

I had to counter your post with this info as it can be misleading to others
