GY Tires & Z66 Rims And A Loss Of PSI

Don't know if this may turn into a bigger problem later on, but our experience with GY tires has never been very good. Our 300M has terrible Eagle LS's that we're howeling noisy, rode & handled poorly, and both vibrated and wobbled constantly.

Our Av Z66 now has the stock OWL Wrangler HP's with 11k miles. Lately, the tires seem to be losing air quite frequently, and not always just a few pounds. We check often, and last week, the one front was down from 35 PSI to 18! You can usually tell to, because the Av starts to wobble more on the road and isn't all that stable feeling.

What's the general life expectancy of these treads? with 11k so far, wear seems to be very minimal and they almost look new. Anyone else seem to be having loss of air problems? Wobble/vibration issues? They still seem to be moderatley quiet and ride quite well, but I think most of that is because of the Av's superior suspension and insulation.

I'll tell you what I would do if it were mine ;D....some new 20"ers and significantly upgraded tires, and maybe a slight suspension tweak to make things just a little tighter on the road.
