Quick advice.... A slow leak started in my rear tire.

Im losing 1 psi about every hour. Tire was down 20 psi this am . this isn’t exactly a slow leak but it’s not a blowout.

Before I waste my time: is a leak producing this rate of air loss one that can maybe be patched or should I just go right for a replacement? I can not find/feel the damage so it’s not a sidewall.

I know it’s not much to go on but I need to leave the car for a whole day just to find out about the patch and if you guys think: “ don’t waste your time, that’s too big of a leak to patch” then I’ll go a different direction

I personally have no problem with a patch plug. Take it to a tire store,

Plug it, as long as it’s not near a sidewall. Don’t use plugged tire on track.

Depends where the leak is located at. If in the repairable area, it should not be any problem. Tire shops will not plug the tire if not located in the proper area.

spray soapy water around the tire, you will pinpoint the leak in 5 mins. 20psi/hr with weight of the car is not bad

All good advice given above. I would add that you should go to an auto parts store and buy a tire plug kit and learn how to use it. It is possible to generally plug a tire while it is inflated and on the car within 5 minutes - no need to hassle with leaving a car at a store, finding a ride, etc.

With the lack of spare tires these days, everyone capable should learn how to plug a tire for street use. Just don't push the limits and try to plug anything near the sidewall as noted above.

By the way, original Windex works great for locating leaks.

Good luck.

Just a thought, but I got a nail on my Cayman S and parlayed it past The Boss into a set of new Michelin P4S. Worth a shot.

Plugging from the outside is great for emergency repair, but a long term fix requires dismounting the tire and installing a patch plug from the inside (after inspecting the inside of the tire for damage--sometimes a tire should not be plugged, even in the tread area).

This. Why take a chance?

If u have wheel/tire insurance the tire will be replaced for free... I dont know what your specific situation is

vodkag

do a plug patch (ones that they remove the tires and do it from the inside) and you be fine

(as long as it is in the repairable area)

Any tire repair means the tire loses its speed rating and is compromised. Keep that in mind if you intend to drive your Porsche aggressively.

Personally, I will never plug the tires on my Porsche, I replace them. My old truck that I take to Home Depot - I have no problem at all with plugs in the tires since its not going very fast to the hardware store.

DIY plug kit s/b only for an emergency till you can get to a tire shop for a proper plug + patch repair, such as done by Discount Tire. (Assuming the leak is in a repairable area & the hole is not too big.)
If you need a new tire, you may want to either buy 2 tires or have the new one shaved to match the tread depth on the other side.
Not good to have significantly different tread depth on same axle.
