The size itself is not a problem.

What air pressure do you have in the tires?

 

I have pressure 50 is that good? or what do you recomend? also how do i reset the tire pressure sensor to this tires? becuase the TPM light comes on, can i take my H3 any where or do I have to take it to de Hummer dealer?
