Hi all, got my new tires ST225/75r15d. they are rated for 65psi for weight of 2540 per tire x4. Now all I read is never fill to max. Mr Big-o tells me the tire is make for 65 psi max.(cold) so going down the heated highway my tires go to 72psi. I really don't know. now on my 2004 Lincoln Navigator they want P275/65R18 and the tire is 44psi max, so fill to 35. is suv tires not like the st tires? they make room for heat, but not the trailer. what is the thinking here?
thanks and happy camping.
