Odd problem
 

I just looked at my right rear tire and it was every low 7.5 lbs. I took it off and did not see any obvious problem. I have filled it back up and will keep an eye on it. if it goes flat again I will bring it somewere to have it looked at.

Here is my problem. I am running Potenza RE750's and they are fairly new. I bought the car with them on it but they can't have more the a couple of thousand miles on them.

So if I do need to replace the tire you can't get the RE750's any more. Should I just replace both back tires and keep the left one for emergences.

If I do decide to do that I would stay with Potenza'a to at least have the same manufacterer on the car.

I was looking at the RE760. Has anyone run these and if so what is your opinion of them.

Also I know there are different tread width's for tires. I looked on Tirerack.com and the 760 has a Tread width 8' and the 750 is 7.2". Is the 760 closer to the OEM spec tire?

Thanks in advance for any help.

mlc

i would just replace both rears if that one tire is not repairable.

I agree. Have the tire checked and if it can not be repaired I would replace the two ties with the RE760. They are the most similar tire with better handling that the RE750.
If I can help let me know.

:iagree:

Could be a slow leak due to a valve stem problem.

A tire store can try to figure it out for you. They can put the tire in a dunk tank and look for the leaks.
