Tyres losing pressure constantly

    Got a 2nd hand 2016 4x4 at end of June and as part of the deal the garage were to put new tyres on. They put on some brand called MRF. In the last 3 weeks the driver side front tyre is loosing up to 1/2 the recommended pressure in less then 36 hours and the other 3 tyres are loosing up the same amount over a few days. I pumped all tyres up Wednesday to recommended pressure and this morning had to do it again. I had thought it might be a slow puncture on 1 tyre but with all tyres loosing pressure Im either thinking the tyres werent fitted/glued properly 1st time and air is seeping out or they are just ****e tryes and its better to replace all with a better brand. Any suggestions??

    I'd start by checking the valves.

    The wheels themselves could also be damaged. Did you see the 4x4 before they fitted the new tires? They could have put new ones on solely because they thought it might be tires and that's a quick way out for'em.

    Fill your bath half full. Pump the tyres and remove the wheel and put in the bath, you should see where air is escaping, mark that with a crayon and check the valve core is tight at the same time.
    The rubber monkeys might have not cleaned the sealing surface well enough to allow the tyre to seat properly.
    Sometimes you get corrosion on the inside of the wheel that stops them sealing as well.
    I'd be inclined to bring it back and find out who fitted the tyres and get them to reseat them with tyre lube.

    I had a cracked alloy before and while the tyre and vales were brand new it kept losing pressure.

    As said already it's either the valves leaking or it's leaking on the rim. Either way you'll need the tyre off or at least have the bead broken down to fix it.
    Find out who done the tyres and bring it back.

    Bit of soapy water onto the valves should show any leakage. Finding a leak on the rim may need the wheels to be taken off and laid flat on the ground (and to check in inside rim)

    Buy a 5e can of sealant and put it in, was having a similar issue and it worked for me no issues in well over a year.

    I know little enough about car tyres but BKT Agrimax are a tractor tyre brand from India and are excellent. Well up there with the competition and good value. Not attacking anyone, just saying.

    Maybe this, I got a 320i a few years back. Keep having to put air in the tyres. Eventually had them looked at. All 4 alloys cracked & had been welded a few times before that.

    I was possibly thinking that too, I had an a4 on 18" rims that had all been cracked and welded too, but a 4x4 would be on much heavier rims with more rubber on the tyres that would be a lot harder broken.

    If the wheels are aftermarket replicas then there would be serious questions about their strength. The OP doesn't mention the wheels on the car, but if they are after market I'd be worried about cracks tbh.

    A good trick to check the seals is to make up a batch of very soapy water and brush it around the bead of the tyre and the valve. You should see bubbles soon enough if there's an issue.

    I've a friend who bought a VW Amarok that had BMW wheels fitted to it.... no idea about the spacing needed for them to work. I told him not to buy it because if somebody is stupid enough to put BMW wheels onto an Amarok....what else have they done? So who knows what rims are on the 4x4?

    Needless to say my friend has had a lot of issues with his Amarok...
