What kinda air pressures a good starting place for 275/50-15 MT ET Street Radials for the strip? ...and the street?

They say 44 psi max, but, they have to be NUTS to run them at anything even close to that, even on the street...

What do you guys that own these tires, think?

Well, if they are designed for 44PSI max Cold Pressure, then you should run atleast 40PSI in them on the street to promote even tread wear, and gain maximum sidewall support.

At the track, I see no reason why you couldn't start at 25PSI and go down. You can get you one of the Pnacake style air compressors to take with you to bring them back up to pressure to drive home.

I am not sure wha the minumum cold air pressure is on them, but I know that some offroad tries are designed to run as low as 15PSI.

Thanks for the reply!
I found some info I thought I would pass on for those interested (from MT's website) ...

MT ET Street Radials...
(on strip)
295 and larger 11 to 14 psi
275 and smaller 12 to 16 psi

NEVER EVER under 11 psi for any of them
and for the drive home (on the street)
75% of the PSI listed on the sidewall.

Designed to heat up quickly, so no long burnouts required

I run 15 psi and found that to be the best pressure.

I ran 17.5 last time and normally run 22 or more. I am not sure I like the lower pressure. My times went up even as the evening got cooler.

I drove to the drag strip last time with my MT's on and it was pretty hot. I think I started out with like 32psi and then it hit me on the way to the track that number would be alot higher when they are hot. Got out and checked them and they were at 44psi.

Moral of the story, if you put them on at the track, recheck your air pressure after your first run. It will be much higher. I usually try to run 20psi.
