I upped the PSI to my tires from 29 to 35 and...

Sweet, I will up my PSi to 75 and see what happens. lol, no, I am kidding, I may go to 40-45 later.

Thanks!

And 55psi isn't a big deal. Search Google for "Factor of Safety" - it's one of the few engineering terms that's to the point in what it is I've been having trouble finding the FoS for modern tires, but bias ply tires were designed with an FoS between 4 and 11 with optimal FoS at 7. That's 7 times what's rated on the side. And, no doubt, modern tires at least meet this criteria. I'm not worried

Plus, added benefit of less tendency to hydroplane (something important to me given my location).

I have mine at 50 (rated at 44 max sidewall). There are lots of guys running higher than max with beautiful and even wear across the tire. As Treb said, modern tires do not bubble out in the middle. Did you read that article I posted a link to in your intro thread?

Yep, I did read it and I shared it with everyone I knew too.

I only worked at the tire shop for a short time, but I did manage to see a LOT of nasty things wrong with tires. Ive seen tires worn in the middle. What else would cause it?

Xcel on cleanmpg has had his tires at 55+ psi for years now. I got to see them a couple weeks ago. Completely even wear across the tread, with some tread depth left (4/32-5/32). And that's at 96,000 miles on 60,000 rated oem tires.

Ok, I have a friend that sooo denying the fact inflating your tires more than what is recommend is BAD, can you guys supply me with more links to prove him wrong that is credible?

[PaleMelanesian]

Oh, and mine are at 60psi right now. Only 10,000 miles so far, so too early to tell about wear.

They're rated max 44psi. My car calls for 32. The last set of tires, I ran at 35psi the whole time, and they wore out on the edges = pressure too low.

I have over 30,000 miles on my tires at 50psi as well (labeled as 44psi max), and they are dead even wear as well, I ended up getting two of them replaced recently after running over some nails and bolts in the road, plugged the tires, inflated them to 50psi again and drove another 2,000+ miles before I got around to replacing the tires, they did just fine with plugs in them at that pressure, other then a slow leak and a little bump where the 3 plugs were, but that bump was there even at the lower pressure.

I managed to get a tread depth gauge years ago. You could use a little ruler instead.

When I got my new tires I checked the tread depth. Slightly deeper in the center than at the outer areas. Been running them at 52-53 psi for about 14K miles now. 44 psi sidewall rating. Still slightly deeper in the center than the outer areas.

I've also heard:

1) They will last longer at higher pressure due to less rubber flexing and heat buildup
(I completely expect that to be true).
and
2) They don't need rotation because they will wear more slowly and cleanly (I'm not sure if I buy that one completely but there's probably LESS need for rotation at higher pressures).

Thanks for all the post, I like reading from people that is actually doing the higher PSI. Learned a lot here...
