Rear tire goes plum flat after two days cant find any thing in it or when I put air in it at 45 psi cant hear any air leak

Check the air lines for leaks especially around the right rear tire area. chances are the flat tire severed or pulled loose one of the lines from compressor

Are your rims bent,causing it to leak out.

It's very possible the rim has a slight bend in it, causing an imperfect bead and a slow leak. Only ways to loose air in a tire are:

1. Loose valve stem
2. Bad bead (contact between the tire and rim)
3. A leak in the tire itself due to a puncture

either a new tyre valve sensor or the reciever ,but in the snow it could have got too cold for the electronics to work ,you might find that when it warms up it will work ok

Your tyres need checking for slow punctures or leaking valves. If you want to do it yourself. You'll need a tub or pool big enough for a complete wheel. Fill it with water, then, remove one wheel at a time and put it in the tub/pool. look for bubbles, the puncture is where the bubble come from.

Of course you could go to a tyre shop and get them to check, once done and you know your tyres are in good order, the only other thought is that it may be someone having fun at your expense, you could get some lockable valve caps.

Hi.

This are rice tires. The pressure depends on what you want to get from your tires.

Ideal pressure for races range from about 5 PSI below maximum pressure to a value near to maximum pressure. A good value for racing will start at about 45 PSI, up to 50 PSI.

Keeping the tires at race pressure (use 45/46, not 50) will give you good performance, but driving will be quite harsh.
For a good performance on everyday driving you can keep the tyres at 35 to 38 PSI, depending on terrain.

Here specs table.

On the driver door opening decal the recommened tire pressures if not there its in the rear door opening and it's in the owers manuel under tires. The kind of whells or options need to be obserbed as the differt options may have different recomended pressures and the rear may have a different than the fornt if all the stickers are gone and the owers manuel is too 32 PSI is a safe best bet some 50 or 45 series tires need as much as 45PSI never put more pressure in the tire than what it says on the sidewall but the maximun pressure is safe but might not give the best ride quailty

Spray some soapy water with a spray bottle on the asi struts and check for leaks first.

when the compressor is running do you hear air blowing off? If so, check the manual blow off valve to see if it stuk open. The regulator controls the pressure check it for leaks

most likely there is a small hole or crack in the tire, and when you drive the rubber gets hot and losens up allowing the hot air inside that is expanding to escape. my recomendation is to replace the tire. better safe than sorry when it comes to tires. good luck to ya
