Leaking/seeping issue with toyo proxes4's on 5zigens fno1r-c
 

Hey guys, I don't know what is wrong but hopefully someone can point me in the right direction. These rims and tires are only a week old. The tires and rims are brand new and nothing is wring with them. It is a 235/40/18 tire on 18x7.5 rims. Air seems to be seeping out where the rim and tire meet. Definitely not the valve stem. why? how? Are toyo proxes known for this issue?

The fronts leak and level out around 25psi and the rears stay at a constant 35 psi. The max psi that the tires can handle is 50... Anyone with some advice would be helpful.

Is 25psi safe to drive on?

If they're new, then there is a warranty. Take it back to the shop and tell them about it. The tire could have been installed improperly or there could be a razor-thin slit somewhere.

are my tires too wide?

I've run 235's on a 7" before, so they should be fine on a 7.5" Check the tire manufacturer to see the recommended range of wheel widths for that particular tire size.

Your tires may be too wide. Toyo recommends 225/45/18's on a 7.5" wide rim. I believe the only other size available for that width is the 245/45/18" Proxes 4.
