ET streets.....

On the street put them at 30. I do not have a problem with the rear end wondering around and I have had it on the expressway. 10 at the track. I do not have tubes. Air will leak from them over time but nothing serious. Tom.
 
I too run about 30 street 10-12 at the track. I have never had any issues and never had them lose air, even over the winter. They hook great but not on the street. Too much dirt, sand, oils, and whatever else is on the road that causes them to slip. You will get better traction than a street radial, but no 5000 launches.

Just dont get caught in the rain!
